Battery over-charge and over-discharge protection system and battery protection method able to release a protection state

摘要

A battery protection system applicable to an electronic device includes a battery, a control module, a message generating module and an input interface. The control module is electrically connected to the battery for detecting if the battery is in an abnormal state. The message generating module is electrically connected to the control module for generating a battery-error warning message when the control module detects that the battery is in the abnormal state. The input interface is electrically connected to the control module for transmitting a user command to the control module after the battery-error warning message is generated, thereby enabling the control module to release the abnormal state of the battery according to the user command. A battery protection method is also provided.

1. A battery protection system for protecting a battery, applicable to an electronic device, the battery protection system comprising:
a control module electrically connected to the battery for detecting an abnormal state of the battery, including an over-charge protection state of the battery; a message generating module electrically connected to the control module for generating a battery-error warning message when the control module detects that the battery is in the abnormal state; and an input interface electrically connected to the control module for transmitting a user command to the control module after the battery-error warning message is generated, thereby enabling the control module to release the abnormal state of the battery according to the user command, wherein the control module is further configured for controlling the electronic device so that when the control module detects that the battery is in the over-charge protection state, the electronic device charges the battery according to the user command after the control module releases said over-charge protection state of the battery.
