Detailed Description
In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 2 is a schematic structural diagram of an electronic device according to an embodiment of the present invention, where the electronic device includes a main control unit 201, and further includes at least two fast charging and charging circuits 202 and a battery 203, where the battery 203 includes a battery cell 211, and charging and discharging interfaces 212 and protection circuits 213 that are the same in number as the fast charging and charging circuits, and the charging and discharging interfaces 212 are positive and negative interfaces of the battery; wherein,
each fast charging circuit 202 is sequentially connected with a corresponding protection circuit 213 and a corresponding battery core 211 through a charging and discharging interface 212 of the battery 203, and each fast charging circuit 202 is connected with the adapter 204;
the main control unit 201 is configured to control at least two fast charging circuits 202 to be powered on to charge the battery 203, send a first voltage control signal to the adapter 204, and control the adapter 204 to output a first fixed voltage, where the first fixed voltage is greater than a working voltage of the battery 203.
Specifically, in the embodiment of the present invention, the electronic device includes at least two fast charging and charging circuits 202 and a battery 203, where the battery 203 includes a battery core 211, and charging and discharging interfaces 212 and protection circuits 213 that are the same in number as the fast charging and charging circuits 202, and each fast charging and charging circuit 202 is sequentially connected to a corresponding protection circuit 213 and the battery core 211 through one charging and discharging interface 212 of the battery 203. When the battery 203 is rapidly charged (fast charged), the main control unit 201 controls at least two fast charging circuits 202 to be powered on, and sends a first voltage control signal to the adapter 204 to control the adapter 204 to output a first fixed voltage for charging the battery 203, wherein the first fixed voltage is greater than the working voltage of the battery 203 in order to ensure the normal charging of the battery.
In order to realize quick charging of the battery cell, the charging current of the battery cell needs to be increased, but along with the increase of the charging current, the heat generation of the quick charging circuit and the protection circuit is increased, for example: when the normal charging mode is adopted (normal charging), the resistance of the quick charging circuit is R1, the resistance of the protection circuit is R2, the charging current corresponding to the charging voltage is I, and the heating power of the normal charging quick charging circuit isI2R1The heating power of the protection circuit is I2R2Total heating power is I2R1+I2R2. In the existing quick charging mode, in order to quickly charge the battery core of the battery, the charging current is increased to 2I, and the heating power of the quick charging circuit is (2I)2R1The heating power of the protection circuit is (2I)2R2Total power of heating is (2I)2R1+(2I)2R2The heating is 4 times of that of the common charge. Because at least two fast charge and charge circuits, a charge and discharge interface of the battery and a corresponding protection circuit are connected in parallel between the battery core and the adapter in the embodiment of the invention, for example, two fast charge and charge circuits connected in sequence, and a charge and discharge interface of the battery and a corresponding protection circuit are connected in parallel between the battery core and the adapter of the battery, when the charging current to the battery core is 2I, the current flowing through each fast charge and charge circuit and the corresponding protection circuit is I, and the heating power of each fast charge and charge circuit is I2R1The heating power of the protection circuit is I2R2Total heating power is 2 (I)2R1+I2R2) The heating is 2 times of the common charging, when the electric core of the battery is rapidly charged with the same charging current 2I, the heating power is one half of the existing rapid charging mode, the heating of the rapid charging circuit and the protection circuit is reduced while the electric core of the battery is rapidly charged, and the damage of the rapid charging circuit and the protection circuit caused by the overheating of the rapid charging circuit and the protection circuit is prevented.
And with the increase of the number of the quick-charging circuits, the charging and discharging interfaces of the battery and the corresponding protection circuits which are connected in parallel and are sequentially connected between the battery cell and the adapter, in order to achieve the same charging effect, the charging current flowing through each quick-charging circuit and each protection circuit is reduced, the heating power of each quick-charging circuit and each protection circuit is reduced, and the total heating power is reduced. For example: four fast charging and charging circuits, a charging and discharging interface of the battery and corresponding protection circuits which are connected in sequence are connected in parallel between the battery cell and the adapter, and the protection circuits are used for protecting the batteryThe charging current of the battery cell is 2I, the charging current flowing through each quick charging circuit and the protection circuit is I/2, and the heating power of each quick charging circuit is (I/2)2R1The heating power of the protection circuit is (I/2)2R2The total heating power is 4((I/2)2R1+(I/2)2R2) When the battery core of the battery is rapidly charged with the same charging current 2I, the heating power is the same as that of the ordinary charging, and is one fourth of that of the existing rapid charging mode, so that the heating of the charging and discharging protection circuit is further reduced.
In the embodiment of the invention, the electronic equipment comprises at least two quick charging circuits and the battery, and when the battery is charged, the main control unit controls the at least two quick charging circuits to be electrified to charge the battery, so that the charging current of the battery is increased, the charging efficiency is improved, and the requirements of users are met.
Example 2:
in order to facilitate the detection of the voltage at the two ends of the battery and the current flowing through the circuit of the protection circuit, the protection circuit 213 includes an electric quantity metering circuit, the electric quantity metering circuit is used for detecting the voltage value at the two ends of the battery and the current value flowing through the protection circuit 213 where the electric quantity metering circuit is located, and the main control unit 201 obtains the voltage value and the current value detected by the electric quantity metering circuit through communication with the electric quantity metering circuit.
Specifically, each of the charge and discharge interfaces further includes a communication interface of the electric quantity metering circuit. Through each charging point electrical interface, the main control unit can obtain the voltage value and the current value detected by the electric quantity metering circuit.
The main control unit 201 obtains the voltage value and the current value detected by the electric quantity metering circuit through communication with the electric quantity metering circuit, and determines the current value for charging the battery 203 through the at least two fast charging circuits 202 which are powered up according to the current value flowing through each protection circuit.
Example 3:
in order to improve the charging efficiency, on the basis of the foregoing embodiments, in an embodiment of the present invention, the main control unit 201 is further configured to send a second voltage control signal to the adapter 204, and control the adapter 204 to increase the output voltage based on the first fixed voltage according to the set first voltage increment so as to increase the first current value of the powered fast charging circuit 202.
Specifically, when the battery is charged, the battery can be charged at a first fixed voltage, and because the first fixed voltage is greater than the operating voltage of the battery, the electric quantity of the battery can be ensured to be increased continuously.
To further improve the charging efficiency, in the embodiment of the present invention, by increasing the output voltage of the adapter 204 connected to the fast charge circuit 202, the current flowing through each powered fast charge circuit 202 can be increased, thereby increasing the current for charging the battery 203.
In this embodiment of the present invention, the main control unit 201 may further send a second voltage control signal to the adapter 204, and control the adapter 204 to increase the output voltage of the adapter 204 according to the first voltage increment on the basis of the first fixed voltage, so as to increase the first current value of the fast charging circuit 202 that is powered on, where the first voltage increment may be a fixed voltage value such as 0.2V, 0.3V, and 0.5V. For example: the first fixed voltage value is 8V, the first voltage increment is 0.2V, and the adapter 204 is controlled to increase the output voltage of the adapter 204 according to the step of 0.2V.
When the adapter increases the output voltage based on the first voltage increment and the first fixed voltage, the output voltage may be increased at a preset time interval, and the time interval may be preset, for example, 5s, 10s, one minute, and the like.
With the increase of the output voltage of the adapter 204, the current for charging the battery 203 is also increased, in order to prevent the battery 203 from being damaged by the excessively fast increase of the current, so as to affect the normal use of the battery 203, on the basis of the above embodiments, in an embodiment of the present invention, the main control unit 201 is further configured to obtain a first current value flowing through the powered fast charging circuit 202, and if the first current value reaches a preset first current threshold, send a third voltage control signal to the adapter 204, control the adapter 204 to increase the output voltage according to a set second voltage increment so as to increase a second current value of the powered fast charging circuit 202, where the second voltage increment is smaller than the first voltage increment, and the second current value is greater than the first current value.
Specifically, after the main control unit 201 controls the adapter 204 to increase the output voltage based on the first fixed voltage according to the set first voltage increment, the main control unit 201 obtains a first current value flowing through the powered fast charging circuit 202. The main control unit 201 is connected to each fast charging circuit, and the main control unit 201 can be used as an element in the fast charging circuit, so that the main control unit 201 can have a current statistics function to count the current flowing through each electrified fast charging circuit; in addition, the main control unit can acquire the current flowing through each electrified quick-charging circuit through communication with the circuit metering circuit. The first current value obtained by the main control unit 201 and flowing through the powered fast charging circuits 202 may be a current value flowing through each powered fast charging circuit 202, a current value of any one of the powered fast charging circuits 202, or a total current value flowing through each powered fast charging circuit 202.
Because the circuit structure of each fast charging circuit is known, the impedance relationship of each fast charging circuit is known, and the first current threshold value can be set according to each fast charging circuit, or the first circuit threshold value can be set according to the number of the electrified fast charging circuits. Wherein the first current threshold is less than the corresponding nominal current value. For example, the total rated current for charging the battery 203 quickly is 8A, and the first current threshold may be set to 5A, 6A, etc.
Preferably, the circuit structure of each fast charging circuit is the same, only one fast charging circuit may be set to set the first current threshold, and if the total current value flowing through each powered fast charging circuit 202 is obtained, the corresponding first current threshold is determined according to the number of the powered fast charging circuits. As long as it is ensured that the obtained first current value corresponds to the adopted first current threshold.
If the first current value reaches a preset first current threshold value, the adapter is controlled to reduce the current acceleration rate, a third voltage control signal is sent to the adapter 204, the adapter 204 is controlled to increase the output voltage according to a set second voltage increment so as to increase a second current value of the powered fast charging circuit 202, wherein the second voltage increment is smaller than the first voltage increment, and the second current value is larger than the first current value.
Since the rated current for charging the battery 203 is constant, when the charging current for the battery 203 reaches the rated current, it is necessary to stop the increase of the charging current, that is, to control the adapter 204 to stop increasing the output voltage, so as to prevent the damage of the battery 203 due to the excessive charging current for the battery 203. The main control unit 201 is further configured to obtain a second current value flowing through the powered fast charging circuit 202; if the second current value reaches a preset second current threshold, a fourth voltage control signal is sent to the adapter 204, and the adapter 204 is controlled to output a second fixed voltage so as to increase the first voltage value at the two ends of the battery 203, wherein the second current threshold is greater than the first current threshold, and the second fixed voltage is greater than the first fixed voltage.
Specifically, the second current threshold may be a rated current value corresponding to the second current threshold, and when the main control unit determines that the second current value reaches the preset second current threshold, it indicates that the current for charging the battery 203 reaches the rated current for charging the battery 203, and the main control unit sends a fourth voltage control signal to the adapter 204, and controls the adapter 204 to output a second fixed voltage to charge the battery 203. At this time, the adapter charges the battery with the second fixed voltage, and the first voltage value output from the two ends of the battery 203 is increased continuously during the continuous charging process.
Example 4:
when the electric quantity of the battery is saturated, the output voltage at the two ends of the battery is constant, and if the battery is charged at the moment, the battery will be damaged, so that on the basis of the above embodiments, in the embodiment of the present invention, the main control unit 201 is further configured to obtain the first voltage value at the two ends of the battery 203, in order to protect the battery and prolong the service life of the battery; if the first voltage value reaches a preset first voltage threshold value, a fifth voltage control signal is sent to the adapter 204, and the adapter 204 is controlled to reduce the output voltage according to a set second voltage increment, wherein the second voltage increment is smaller than the first voltage increment.
Specifically, the first voltage threshold may be not greater than an output voltage when the electric quantity of the battery is saturated, and if the first voltage output from the two ends of the battery reaches a preset first voltage threshold, it indicates that the current electric quantity of the battery 203 is close to saturation, and at this time, the control adapter 204 reduces the output voltage output to the fast charging circuit, reduces the charging current of the battery 203, and avoids damage of overcharging the battery.
Example 5:
in order to prevent the damage of the overcharge of the battery 203, the main control unit 201 is further configured to obtain a third current value flowing through the powered fast charging circuits 202 after the adapter 204 decreases the output voltage according to the set second voltage increment, and if the third current value is smaller than a preset third current threshold, close at least one fast charging circuit 202 in the powered fast charging circuits 202.
With the continuous charging of the battery 203, the electric quantity of the battery 203 continuously increases, the output voltage at two ends of the battery 203 continuously increases, and with the decrease of the output voltage by the adapter 204 according to the set second voltage increment, the difference between the voltage output by the adapter 204 and the output voltage at two ends of the battery 203 continuously decreases, so that the current for charging the battery 203 continuously decreases, if a third current value flowing through the powered fast charging circuit 202 acquired by the main control unit 201 is smaller than a preset third current threshold, it is indicated that the current electric quantity of the battery 203 is close to saturation, in order to prevent the damage of the battery overcharge, at least one fast charging circuit 202 in the powered fast charging circuits 202 is turned off, and the current for charging the battery 203 is reduced by reducing the number of the powered fast charging circuits 202.

Example 8:
the embodiment of the invention provides a charging control method based on the electronic equipment, which is applied to a main control unit in the electronic equipment and comprises the following steps:
the method comprises the steps of controlling at least two quick charging circuits to be powered on to charge a battery, sending a first voltage control signal to an adapter, and controlling the adapter to output a first fixed voltage, wherein the first fixed voltage is larger than the working voltage of the battery.
Specifically, when the battery is charged quickly, at least two quick charging circuits are controlled to be powered on, and a first voltage control signal is sent to the adapter, so that the adapter is controlled to output a first fixed voltage to charge the battery. To ensure normal charging of the battery, the first fixed voltage is greater than the operating voltage of the battery.
In the embodiment of the invention, when the battery is charged, the battery is charged by electrifying at least two quick charging circuits, so that the charging current of the battery is increased, the charging efficiency is improved, and the requirements of users are met.
Example 9:
in order to improve the charging efficiency, on the basis of the foregoing embodiments, in an embodiment of the present invention, the method further includes:
and sending a second voltage control signal to the adapter, and controlling the adapter to increase the output voltage based on the first fixed voltage according to the set first voltage increment so as to increase the first current value of the electrified quick-charging circuit.
Specifically, when the battery is charged, the battery can be charged at a first fixed voltage, and because the first fixed voltage is greater than the operating voltage of the battery, the electric quantity of the battery can be ensured to be increased continuously.
In order to further improve the charging efficiency, in the embodiment of the invention, by increasing the output voltage of the adapter connected with the quick-charging circuit, the current flowing through each powered quick-charging circuit can be increased, so that the current for charging the battery is increased.
In the embodiment of the present invention, a second voltage control signal may be further sent to the adapter, so as to control the adapter to increase the output voltage of the adapter according to a first voltage increment on the basis of the first fixed voltage, so as to increase the first current value of the fast charging circuit 202 powered on, where the first voltage increment may be a fixed voltage value such as 0.2V, 0.3V, or 0.5V. For example: the first fixed voltage value is 8V, the first voltage increment is 0.2V, and the control adapter 204 increases the output voltage of the adapter 204 in 0.2V steps at set time intervals.
When the adapter increases the output voltage based on the first voltage increment and the first fixed voltage, the output voltage may be increased at a preset time interval, and the time interval may be preset, for example, 5s, 10s, one minute, and the like.
In order to prevent the battery from being damaged by the excessively fast increase of the current and thereby affecting the normal use of the battery, on the basis of the above embodiments, in an embodiment of the present invention, the method further includes:

and if the first current value reaches a preset first current threshold value, sending a third voltage control signal to the adapter, and controlling the adapter to increase the output voltage according to a set second voltage increment so as to increase a second current value of the electrified quick-charging circuit, wherein the second voltage increment is smaller than the first voltage increment, and the second current value is larger than the first current value.
Specifically, after the output voltage is increased based on the first fixed voltage according to the set first voltage increment, a first current value flowing through the electrified fast charging circuit is obtained. The first obtained current value flowing through the powered fast charging circuits may be a current value flowing through each powered fast charging circuit, a current value of any one of the powered fast charging circuits, or a total current value flowing through each powered fast charging circuit.
Because the circuit structure of each fast charging circuit is known, the impedance relationship of each fast charging circuit is known, and the first current threshold value can be set according to each fast charging circuit, or the first circuit threshold value can be set according to the number of the electrified fast charging circuits. Wherein the first current threshold is less than the corresponding nominal current value. For example, the total rated current for charging the battery 203 quickly is 8A, and the first current threshold may be set to 5A, 6A, etc.
Preferably, the circuit structure of each fast charging circuit is the same, only one fast charging circuit may be set to set the first current threshold, and if the total value of the current flowing through each powered fast charging circuit is obtained, the corresponding first current threshold is determined according to the number of the powered fast charging circuits.

Because the rated current of the battery during quick charging is constant, when the charging current of the battery reaches the rated current, the increase of the charging current needs to be stopped, namely, the adapter is controlled to stop increasing the output voltage, so that the damage of the battery caused by the overlarge current for charging the battery is prevented. After controlling the adapter to increase the output voltage by the set second voltage increment, the method further comprises:
acquiring a second current value flowing through the electrified quick charging circuit;
and if the second current value reaches a preset second current threshold value, sending a fourth voltage control signal to the adapter, and controlling the adapter to output a second fixed voltage so as to increase the first voltage value at the two ends of the battery, wherein the second current threshold value is greater than the first current threshold value, and the second fixed voltage is greater than the first fixed voltage.
Specifically, the second current threshold may be a rated current value corresponding to the second current threshold, and when it is determined that the second current value reaches the preset second current threshold, it indicates that the current for charging the battery reaches the rated current for charging the battery, and sends a fourth voltage control signal to the adapter, so as to control the adapter to output a second fixed voltage to charge the battery. At the moment, the adapter charges the battery at the second fixed voltage, and the first voltage value output by the two ends of the battery is increased continuously in the continuous charging process.
