Description

Charging method and related equipment Technical Field The application relates to the technical field of charging, in particular to a charging method and related equipment. Background When an electronic device such as a personal computer (Personal Computer, a PC) is charged through the adapter, in a high-load scene such as a heavy-load game, a power failure situation is easy to occur, so that the electronic device can not be charged, a performance mode can be exited, and a displayed charging icon can be switched back and forth, thereby affecting the use of a user. Disclosure of Invention The application provides a charging method and related equipment. According to the method, the electronic equipment can adaptively adjust relevant parameters of the adapter, such as parameters for indicating peak current of the adapter, delay time for determining peak current of the adapter and the like, so that maximum output power of the adapter is improved, the peak current of the adapter is determined by delay, response time of discharging of the battery can be adaptively adjusted by the electronic equipment, the adapter delays switching from a charging mode to a discharging mode, frequency of power failure of a system is reduced, frequency of switching from a charging management module to the discharging mode is reduced, and continuous discharging of the battery is avoided. In a first aspect, the present application provides an electronic device. The electronic device may include a charge management module, a controller, and a battery. The charge management module in the electronic device may be connected to the controller in the electronic device and the battery in the electronic device, respectively. The charge management module in the electronic device may also be connected to the adapter. The charge management module may be configured to receive the power output by the adapter and charge a battery in the electronic device. The controller may be configured to send at least one of the first current parameter and the first duration to the charge management module and send the first information when the adapter is in an operational state and the system is powered down (i.e., the electronic device is powered down). The charging management module may be further configured to maintain the operation mode of the charging management module in the charging mode when it is determined that the duration of the system power failure is less than the first duration based on the first information. Wherein the first current parameter may be used to indicate a peak current of the adapter, which may be used to determine a maximum output power of the adapter. The first current parameter indicates that the peak current of the adapter is greater than the current peak current of the adapter. The first duration may be used to indicate a waiting duration between receiving indication of a power down of the system by the charge management module and switching the operating mode to the discharging mode. The first time period is greater than the current waiting time period, i.e., the first time period may be greater than the waiting time period currently set by the electronic device. The first information may be used to indicate that the system is powered down. In the scheme provided by the application, when the charging management module in the electronic equipment is in a charging mode (namely, the charging management module receives the power output by the adapter to charge the battery), if the adapter is in a working state and the system is powered down, the adapter can adjust at least one of the first current parameter and the first duration, and then the obtained first current parameter and/or the first duration are sent to the charging management module. The charging management module can improve the peak current of the adapter based on the first current parameter, so that the maximum output power of the adapter is improved, the power-down frequency of the system is reduced, the frequency of switching the working mode to the discharging mode and the probability of successfully switching the working mode to the discharging mode can be reduced to a certain extent, and continuous discharging of the battery is avoided. The charging management module can further increase the waiting time between receiving the indication information of the power failure of the system and switching the working mode to the discharging mode based on the first time, so that the electronic equipment is not powered down before the charging management module starts to switch the working mode. It should be noted that, under the condition that the controller adjusts the first current parameter to increase the peak current of the adapter and increases the first time length, on one hand, because the first time length increases, the controller has sufficient time to complete the adjustment of the first current parameter before the charge management module starts to switch t
