In this embodiment, for convenience of description, the following description will be made with the charger as the main body of execution.
Currently, a battery is a common component for generating electric energy, and is widely applied to various mobile devices. The types of batteries are various, including lithium batteries, lead-acid batteries, and nickel-chromium batteries. Different batteries have different electrical characteristics, and therefore, different electrical parameters such as charging voltage and charging current are required for charging.
However, the existing charger cannot accurately identify the type of the connected battery, so that potential safety hazards exist when the battery is charged.

It should be noted that, the execution body of the present embodiment may be a computing service device having functions of data processing, network communication, and program running, such as a charger. The present embodiment and the following embodiments will be described below with reference to a charger.
The charger applied to the implementation of the technology of the present application will be described below:
referring to fig. 1, fig. 1 is a schematic view of the internal structure of a charger. The charger comprises a battery connection terminal, a voltage detection circuit, a current detection circuit, a relay, a power circuit and a micro-processing controller.
The battery connecting terminal is respectively connected with the microprocessor controller, the voltage detection circuit, the current detection circuit and the relay, and is used for being connected with the battery.
The voltage detection circuit is respectively connected with the micro-processing controller and the battery connecting terminal, and comprises a high-precision voltage divider circuit and an analog-to-digital converter (ADC), and after the voltage detection circuit acquires the initial voltage and the on-load voltage of the battery through the voltage divider circuit, the analog-to-digital converter is used for converting the initial voltage and the on-load voltage into voltage digital signals, and the digital signals are transmitted to the micro-processing controller.
The current detection circuit is respectively connected with the micro-processing controller and the battery connecting terminal, and comprises a high-precision current sampling circuit and an analog-to-digital converter (ADC), and after the current detection circuit collects the current of the battery during charging through the current sampling circuit, the current value is converted into a current digital signal by the analog-to-digital converter, and the current digital signal is transmitted to the micro-processing controller.
The relay is connected with the micro-processing controller, the battery connecting terminal and the power circuit respectively, and is used for stopping charging the battery or continuing to charge the battery according to the control signal when receiving the control signal sent by the micro-processing controller.
The power circuit is connected with the micro-processing controller and is used for outputting current and voltage under the control of the micro-processing controller.
When the micro-processing controller detects that the micro-processing controller is connected with the battery through the battery connecting terminal, the micro-processing controller receives a voltage digital signal of the initial voltage sent by the voltage detecting circuit and controls the power circuit to output current and voltage so as to initially charge the battery. After the battery is initially charged, the voltage digital signal of the first current carrying voltage sent by the voltage detection circuit is received, the current digital signal of the first current sent by the current detection circuit is received, and the target battery type of the battery is determined according to the first current, the first current carrying voltage and the initial voltage. After determining the target battery type of the battery, a charging parameter corresponding to the target battery type may be determined, and the current and voltage output by the power circuit may be controlled according to the charging parameter.
In this embodiment, according to the initial voltage of the battery when connected to the charger, and the parameters such as the first current and the first current load voltage after the initial charging, the reaction characteristics of the battery, such as the internal impedance and the voltage change, can be analyzed, so that the target battery type of the battery can be deduced according to the internal impedance and the voltage change of the battery. Meanwhile, after the target battery type of the battery is determined, charging parameters such as charging voltage, charging current, charging time and the like suitable for the battery can be determined according to the target battery type, so that the charging efficiency can be effectively improved, the service life of the battery is prolonged, overcharge, overdischarge or improper charging current can be avoided, the risks of thermal runaway and damage are reduced, and potential safety hazards during battery charging are avoided.
In addition, when the battery is charged, the voltage and the current output by the power circuit are adaptively adjusted by using the charging parameters, so that the charger is suitable for batteries in different types and states, and the applicability of the charger is improved.
Based on this, an embodiment of the present application provides a battery charging method, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the battery charging method of the present application.
In this embodiment, the battery charging method includes steps S10 to S40:
step S10, when connection with the battery is detected, initial voltage of the battery is collected, and the battery is initially charged.
Step S20, collecting a first current and a first current load voltage of the battery.
In this embodiment, the initial voltage may be a voltage when the battery has not been charged yet. The first current on-load voltage may be a voltage of the battery at a current time after the charger is connected and charging is started. The first present current may be a current through the battery at a present time after the battery is connected to the charger and charging is started.
Specifically, when the charger detects that the charger is connected with the battery through the battery connecting terminal, the initial voltage of the battery can be collected through the voltage detection circuit, and the power circuit is controlled to output current and voltage to initially charge the battery.
It should be noted that, in order to reduce short-circuit or other safety risks of the battery during initial charging, and ensure safer charging process, as an alternative embodiment, initial charging of the battery may be adapted to be constant-current charging of the battery, that is, charging the battery with a set initial constant current value.
After the battery is initially charged, a first current on-load voltage of the battery can be acquired through a voltage detection circuit, and a first current through the battery can be acquired through a current detection circuit.
Step S30, determining a target battery type of the battery based on the first present current, the initial voltage, and the first present on-load voltage.
It will be appreciated that different types of batteries (e.g., lithium ion, lead acid, nickel hydrogen, etc.) have different internal resistance characteristics, and thus when determining a target battery type for the battery based on a first present current, an initial voltage, and a first present on-load voltage, a first internal resistance of the battery may be determined based on the first present current, the initial voltage, and the first present on-load voltage. After determining the first internal resistance of the battery, a mapping relation can be searched for, a target battery type corresponding to the first internal resistance is determined, namely, a voltage difference between an initial voltage and a first current on-load voltage is determined, the first internal resistance of the battery is determined based on the voltage difference and the first current, the mapping relation is searched for, and the target battery type corresponding to the first internal resistance is determined, wherein the mapping relation comprises the mapping relation between the first internal resistance and the battery type.
Step S40, determining a charging parameter corresponding to the target battery type based on the target battery type, and charging the battery using the charging parameter.
In order to prevent the situation that the battery aging causes the target battery type of the battery to be determined to be wrong when the battery is charged by using the charging parameters, further, as an optional implementation manner, after step S40, the method further includes:
step S41, under the condition that the battery is detected to enter the next charging stage, collecting a second current carrying voltage and a second current of the battery.
Step S42, the battery is stopped from being charged.
Step S43, collecting a third voltage of the battery.
Step S44, determining a second internal resistance of the battery using the third voltage, the second current on-load voltage, and the second current.
Step S45, searching the mapping relation and determining a new battery type corresponding to the second internal resistance.
Step S46, it is determined whether the new battery type is consistent with the target battery type.
In step S47, if the new battery type is inconsistent with the target battery type, the charging of the battery is stopped.
In step S48, if the new battery type is consistent with the target battery type, the battery is charged in the next charging stage.
Specifically, the charging process of the battery is mainly divided into three charging stages of trickle stage, constant current stage and constant voltage stage. During battery charging, it may be determined whether the battery enters the next charging stage by the battery voltage.
For example, the voltage detection circuit may collect the battery voltage of the battery, after the battery voltage is collected, the charging stage of the battery may be determined according to the battery voltage range corresponding to each charging stage, for example, the battery voltage is 3.9V, the battery voltage in the trickle stage is lower than 3V, the battery voltage in the constant-current stage is 3.0V to 4.2V, and the battery voltage in the constant-voltage stage is not lower than 4.2V, where the charging stage of the battery may be determined to be the constant-current stage.
And under the condition that the battery is detected to enter the next charging stage, acquiring a second current carrying voltage of the battery through a voltage detection circuit, and acquiring a second current of the battery through a current detection circuit. After the second current load voltage and the second current of the battery are collected, the relay can be controlled to be disconnected, the battery is stopped from being charged, and the third voltage of the battery is collected. In order to obtain a more accurate battery voltage, the step S43 may be adapted to collect the third voltage of the battery after stopping the charging for a preset period of time, for example, after stopping the charging for 2-3 seconds, and collect the third voltage of the battery through a voltage detection circuit.
After the third voltage, the second current load voltage, and the second current of the battery are obtained, a voltage difference between the second current load voltage and the third voltage may be determined, and a second internal resistance of the battery may be determined based on the voltage difference between the second current load voltage and the third voltage, and the second current. After the second internal resistance is obtained, the mapping relation can be searched, a new battery type corresponding to the second internal resistance is determined, and whether the new battery type is consistent with the target battery type or not is determined.
When the new battery type is inconsistent with the target battery type, the battery may be aged to cause detection errors, and in order to avoid equipment failure caused by charge mismatch, the battery is stopped from being charged. When the new battery type is consistent with the target battery type, the battery is not in a situation of detecting errors, and the battery is charged in the next stage.
In this embodiment, when the battery enters the next stage, the second internal resistance of the battery is determined based on the third voltage, the second current load voltage and the second current, the new battery type of the battery is determined by using the second internal resistance, whether the new battery type is consistent with the target battery type is determined, and whether to continue charging the battery is determined according to the comparison result, that is, when the battery enters the next charging stage, the battery type of the battery is identified, so that detection errors caused by battery aging are avoided, and accuracy of battery type identification is ensured.
It will be appreciated that different battery types have specific charging requirements, such as voltage, current and charging time. If mismatched charging parameters are used, overcharging, shorting, or other safety hazards may result, and even fire or explosion may be initiated. After determining the target battery type of the battery, it may be determined whether a charging parameter corresponding to the target battery type exists in the charging data stored inside the charger, and when the charging parameter corresponding to the target battery type exists, the battery is charged by using the charging parameter. And stopping charging the battery when the charging parameter corresponding to the target battery type does not exist, namely determining whether the charging parameter corresponding to the target battery type exists, if so, charging the battery by using the charging parameter, and if not, stopping charging the battery.
In this embodiment, since the different types of batteries have unique electrical characteristics, according to the initial voltage of the battery when connected to the charger, and the parameters such as the first current and the first current load voltage after the initial charging, the reaction characteristics of the battery, such as the internal impedance and the voltage change, can be analyzed, so that the target battery type of the battery can be deduced according to the internal impedance and the voltage change of the battery. Meanwhile, after the target battery type of the battery is determined, charging parameters such as charging voltage, charging current, charging time and the like suitable for the battery can be determined according to the target battery type, so that the charging efficiency can be effectively improved, the service life of the battery is prolonged, overcharge, overdischarge or improper charging current can be avoided, the risks of thermal runaway and damage are reduced, and potential safety hazards during battery charging are avoided.
