In an embodiment of the present disclosure, the calculating the total electric energy conversion efficiency of each charging current distribution scheme according to at least the electric energy conversion efficiency function of each charging management unit includes:
and calculating the total electric energy conversion efficiency of each charging current distribution scheme according to the electric energy conversion efficiency function, the output charging voltage and the input charging voltage of each charging management unit.

according to the following formula:
wherein,

Fig. 2 is a flowchart of a charging method according to an embodiment of the disclosure. As shown in fig. 2, the method includes the following steps.
In step S201, an electric energy conversion efficiency function of each of at least two charging management units is obtained, where the electric energy conversion efficiency function is used to indicate a numerical relationship between the electric energy conversion efficiency of each charging management unit and the output charging current.
As shown in fig. 3, the electronic device is configured with at least two charging management units, the at least two charging management units are connected in parallel with each other, the at least two charging management units are both connected with the charging interface, so as to input a charging voltage from the charging interface, and the at least two charging management units are both connected with the battery, so as to output a charging current to the battery. In the embodiment of the present disclosure, in order to improve the electric energy conversion efficiency during charging, each charging management unit may be further connected to a processor configured in the electronic device, so that the processor may control the output charging current of each charging management unit according to a charging current distribution scheme. It should be noted that the charging management unit may be an independent charging management chip, or may be a functional unit in an integrated chip, and the specific form of the charging management unit is not limited in this disclosure.
The electric energy conversion efficiency of the charging management unit refers to the ratio of the output electric energy to the input electric energy. Specifically, the charging management unit outputs a charging current with a specified intensity to the battery electric core based on the input charging voltage, so as to realize a charging process, in which the electric energy input into the charging management unit often cannot be converted into the output electric energy, that is, for a charging management unit, the ratio of the output electric energy to the input electric energy is smaller than 1.
The present disclosure recognizes that there is a specific numerical relationship between the electrical energy conversion efficiency of the charge management unit and the output charging current, which may be represented by an electrical energy conversion efficiency function. This electrical energy conversion efficiency function is described in more detail below in conjunction with fig. 4. Fig. 4 is a diagram illustrating a function of the electric energy conversion efficiency of the charge management unit a, with the abscissa representing the intensity of the output charging current and the ordinate representing the electric energy conversion efficiency. As can be seen from fig. 4, for the charging management unit a, each intensity of the output charging current corresponds to an electric energy conversion efficiency, for example, as shown in fig. 4, for the charging management unit a, when the output charging current is 1A, the electric energy conversion efficiency is 91%.
Further, the electric energy conversion efficiency of the charging management unit has a specific numerical relationship with the output charging voltage, and the electric energy conversion efficiency function may have a plurality of variables, so that the numerical relationship between the electric energy conversion efficiency of the charging management unit and the output charging voltage may be indicated. Fig. 5 is a schematic diagram of the power conversion efficiency function of the charge management unit a considering different output voltages. As can be seen from fig. 5, when the output charging current is the same, the electric energy conversion efficiency is different for different output charging voltages, for example, as shown in fig. 5, for the charging management unit a, the output charging current is 1A, when the output charging voltage is 3.6V, the electric energy conversion efficiency is 91%, and when the output charging voltage is 3.9V, the electric energy conversion efficiency is 90%.
The present disclosure also recognizes that the power conversion efficiency of each of at least two charging management units configured with the electronic device is different for each of the charging management units. Fig. 6 is a diagram illustrating a function of the electric energy conversion efficiency of the charge management unit B. Comparing the electric energy conversion efficiency functions of the charging management unit a in fig. 5, it can be seen that the electric energy conversion efficiency functions of the charging management unit a and the charging management unit B are different.
Based on the above-mentioned knowledge, in order to improve the total electric energy conversion efficiency when the at least two charging management units configured in the electronic device output the charging current together, it is necessary to obtain the electric energy conversion efficiency function of each of the at least two charging management units, perform calculation based on the electric energy conversion efficiency function of each of the at least two charging management units, and further determine the optimal charging current allocation scheme. In practical application, the electric energy conversion efficiency function can be detected when the electronic device leaves a factory, stored in the electronic device and then acquired when needed, or the working condition of the electronic device can be detected by the charging management unit when the electronic device is charged and then acquired when needed.
In step S202, at least two charging current distribution schemes are determined according to the required total charging current and the number of the charging management units.
The charging current distribution scheme is a scheme for determining how much charging current each of the charging management units needs to output. For example, for an electronic device configured with two charge management units, a charge current distribution scheme may be determined, the charge current distribution scheme including: the charging management unit a outputs a charging current of 1.1A, and the charging management unit B outputs a charging current of 0.9A.
In a preferred embodiment of the present disclosure, in order to accurately control the total output charging current, the above-determined charging current distribution scheme should satisfy certain conditions. Specifically, the at least two charging current distribution schemes are determined according to the required total charging current and the number of the charging management units, so that in each charging current distribution scheme, the sum of the charging currents output by each charging management unit is equal to the required total charging current. For example, when the total required charging current is 2A and 2 charging management units are configured, then in the determined charging current distribution scheme, the sum of the charging currents output by each of the 2 charging management units should be 2A, that is, the charging current distribution scheme may be: the charging management unit a outputs a charging current of 1.1A, and the charging management unit B outputs a charging current of 0.9A, instead of: the charging management unit a outputs a charging current of 1.1A, and the charging management unit B outputs a charging current of 1.2A.
In step S203, a total electric energy conversion efficiency of each charging current distribution scheme is calculated according to at least the electric energy conversion efficiency function of each charging management unit.
In the implementation of the present disclosure, the total electric energy conversion efficiency of each charging current distribution scheme of the at least two charging current distribution schemes is calculated according to the electric energy conversion efficiency function of each charging management unit and the output charging voltage and the input charging voltage. Specifically, according to the formula:
wherein,
calculating the total electric energy conversion efficiency of each charging current distribution scheme in the at least two charging current distribution schemes;
in the formula, the first step is that,represents the electric energy conversion efficiency function, VinRepresents the input charging voltage, VoutIndicating the output charging voltage, n indicating the number of charge management units, s indicating the reference number of charge management units,indicates the input charging current of the charge management unit with reference number s,denotes the output charging current, Q, of a charge management unit denoted by the reference statolRepresenting the overall power conversion efficiency of either charging current distribution scheme.
For example, for one charging current distribution scheme: the charging management unit A outputs a charging current of 1.1AThe charging management unit B outputs a charging current of 0.9AAssume that the output charging voltage is 3.6V (V)out3.6V), charging voltage 5V (V) is inputin5V), the function of the electric energy conversion efficiency of the charge management unit a is shown in fig. 5, and it can be determined from fig. 5 that the electric energy conversion efficiency of the charge management unit a is 92%The function of the electric energy conversion efficiency of the charging management unit B is shown in FIG. 6, and according to FIG. 6, it can be determined that the electric energy conversion efficiency of the charging management unit B is 85%Then:
calculating to obtain:
that is, the total electric energy conversion efficiency of the one charging current distribution scheme was determined to be 89.6%.
It should be noted that, the above process of calculating the total electric energy conversion efficiency only takes the case of "calculating according to the electric energy conversion efficiency function of each charging management unit, the output charging voltage and the input charging voltage" as an example to illustrate the charging method provided by the present disclosure, and in practical applications, the total electric energy conversion efficiency may also be calculated according to the electric energy conversion efficiency function of each charging management unit in combination with other charging parameters, for example, the total electric energy conversion efficiency is calculated according to the electric energy conversion efficiency function of each charging management unit, the output power and the input charging voltage, and the present disclosure does not limit the specific implementation manner of calculating the total electric energy conversion efficiency.
In step S204, a target charging current distribution scheme is determined according to the total electric energy conversion efficiency of each charging current distribution scheme, wherein the target charging current distribution scheme has the highest total electric energy conversion efficiency among the at least two charging current distribution schemes.
In the embodiment of the present disclosure, the total electric energy conversion efficiency of each charging current distribution scheme is compared, and the charging current distribution scheme with the highest total electric energy conversion efficiency is determined as the target charging current distribution scheme. For example, for two charging current distribution schemes, the first one outputs a charging current of 1.1A for the charging management unit a, the charging management unit B outputs a charging current of 0.9A, and the total electric energy conversion efficiency is determined to be 89.6% by calculation, the second one outputs a charging current of 1A for the charging management unit a, and the charging management unit B outputs a charging current of 1A, and the total electric energy conversion efficiency is determined to be 88.4% by calculation, because the total electric energy conversion efficiency of the first one is the highest among the two charging current distribution schemes, the first charging current distribution scheme is determined as the target charging current distribution scheme.
Further, for the plurality of charging current distribution schemes, the charging current distribution scheme with the highest electric energy conversion efficiency may be determined by sorting the plurality of charging current distribution schemes according to the electric energy conversion efficiency.
In step S205, each of the charge management units is controlled to output a charging current according to the target charging current distribution scheme.
In the embodiment of the present disclosure, a control command carrying a target charging current distribution scheme is sent to the charging management unit through the control interface of each charging management unit, so that the charging management unit outputs the charging current according to the target charging current distribution scheme. The specific form of the control command may be a control current, and may also be other forms, for example, a digital control signal, etc., which is not limited by this disclosure.
According to the charging method provided by the embodiment of the disclosure, an electric energy conversion efficiency function of each charging management unit in at least two charging management units is obtained; determining at least two charging current distribution schemes; calculating the total electric energy conversion efficiency of each charging current distribution scheme at least according to the electric energy conversion efficiency function of each charging management unit; determining a target charging current distribution scheme according to the total electric energy conversion efficiency of each charging current distribution scheme; and controlling each charging management unit to output charging current according to the target charging current distribution scheme. By adopting the charging method, when the plurality of charging management units output the charging current together, each charging management unit can output the charging current according to the distribution scheme with the highest total electric energy conversion efficiency, and further, on the basis of ensuring the charging speed, the electric energy conversion efficiency in the charging process is improved.
