A reverse charging device is a device that receives electrical energy provided by an electronic device as a power source. During reverse charging, the electronic device and the reverse charging device need to be kept within a chargeable distance range. When the charging request indication is a reverse charging indication, the electronic device can detect whether there is a reverse charging device. Specifically, when the electronic device receives a charging request sent by a reverse charging device, it determines that a reverse charging device exists; the electronic device A reverse charging enable signal may also be sent through the coil, and when a connection request from a reverse charging device based on the reverse charging enable signal is received, it is determined that a reverse charging device exists.

The charging power of the first charging mode is lower than the charging power of the second charging mode. Equivalently, the first charging mode is a general charging mode; the second charging mode is a fast charging mode.

The second power threshold is a preset power threshold corresponding to forward charging of the electronic device. In one embodiment, wired charging and wireless charging may correspond to different power thresholds. The second power threshold can be set according to application requirements, and is not set here. For example, the second charge threshold may be 20%, 30%, 40%, 50%, or the like.

When the real-time detection that the remaining power value is greater than the second power threshold value, it can switch to the first charging mode to perform the charging operation. For example, when the charging request indication is a wireless charging indication, if the remaining power value is greater than the second power threshold, the electronic device can use the wireless general charging mode to perform the charging operation; if the remaining power value is less than or equal to the second power threshold, the electronic device The wireless fast charging mode can be used for the charging operation, and when the remaining power value during the charging process is greater than the second power threshold value, the charging operation is switched to the wireless general charging mode.

In one embodiment, if the charging request indicates that multiple charging modes cannot be supported, the electronic device may perform the charging operation according to the charging request indicating the corresponding charging power.

FIG. 3 is a flow chart of performing a charging operation in one embodiment. As shown in FIG. 3, in one embodiment, the provided charging management method further includes:

Step 302: Obtain the measured temperature of the battery during the charging process and the corresponding initial charging parameters, and obtain the predicted temperature according to the preset control function and the initial charging parameters.

The measured temperature is the battery temperature detected by the electronic device in real time during the charging process. The initial charging parameter is the charging parameter used by the electronic device when the measured temperature is detected. The charging parameters may be charging voltage, charging current, and the like.

The control function is used to express the functional relationship between the charging parameters and the ideal temperature. The electronic device can preset the control function, and substitute the initial charging parameters into the control function, that is, the corresponding predicted temperature can be obtained. Taking the charging parameter as the charging voltage as an example, during the charging process, the charging voltage and the battery temperature are usually distributed around the sine function, and the electronic device can use the sine function as the preset control function.

Step 304: Obtain the temperature error and the error change rate between the measured temperature and the predicted temperature.

The temperature error is the difference between the measured temperature and the predicted temperature. The error rate of change can be expressed as the difference between the last temperature error and the current temperature error.

Step 306 , analyze the predicted temperature deviation corresponding to the measured temperature and the temperature error through the error inverse model.

The error back model may be a (back propagation) neural network model. The error inverse model is a neural network model that uses the gradient descent method and gradient search technology to minimize the error mean square error between the actual output value and the expected output value of the model. The electronic device can input the error inverse model according to the measured temperature and temperature error during the charging process, and the error inverse model can learn from the measured temperature and the temperature error, and can obtain the predicted temperature deviation corresponding to the measured temperature and the temperature error. The predicted temperature deviation may include at least one of deviation proportion, deviation integral, and deviation differential.

Step 308 , obtain target charging parameters according to the temperature error, the error rate of change and the predicted temperature deviation through the deviation control algorithm, and perform the charging operation according to the target charging parameters through the power supply controller.

The deviation control algorithm is a control algorithm that corrects the deviation of the feedback output by the control object through closed-loop control. Optionally, the deviation control algorithm may include a PID (Proportion Integral Differential, proportional, integral and differential) algorithm. The electronic device can obtain the target charging parameter according to the temperature error, the error rate of change and the predicted temperature deviation through the deviation control algorithm, and perform the charging operation according to the target charging parameter through the power supply controller.

During the charging process of the electronic device, the electronic device can cyclically execute the charging operation process provided in Figure 3 to achieve closed-loop control of the battery temperature, avoid serious battery heating during the charging process, and improve the accuracy of charging temperature control and battery stability.

FIG. 4 is a schematic diagram of battery charging temperature control provided by an embodiment. As shown in Figure 4, the entire battery charging temperature control process is a closed-loop control process. The electronic device detects the measured temperature Y of the battery in real time, and the predicted temperature X can be obtained by substituting the measured temperature Y into the control function X=T0sin(ωt), thereby obtaining the temperature error e between the measured temperature Y and the predicted temperature X, and the error change rate de/dt, where de/dt=e(t)-e(t-1); then, the error inverse model can perform self-learning on the state between the predicted temperature X and the temperature error e obtained by the control function, Obtain the predicted temperature deviation Kp, Ki, Kd; the deviation control algorithm can determine the target charging voltage according to the predicted temperature deviation Kp, Ki, Kd, the temperature error e and the error rate of change de/dt, and the battery is charged by the power controller according to the target charging voltage. Carry out the charging operation.

By introducing the error reverse mode to self-learn the state between the control function and the error, the adjusted predicted temperature deviation can be obtained to calculate the target charging parameter, which can avoid the large over-adjustment of the deviation control algorithm and cause the charging stability. The low problem can improve the charging stability, and the introduction of the error rate of change can speed up the dynamic response speed of the temperature control, reduce the adjustment time, and improve the performance.
