Abstract: A battery detection circuit and a battery detection method are provided. The battery detection circuit includes battery gauge circuits and a processing circuit. The battery gauge circuits read battery information of batteries, and the battery information at least includes a current battery capacity, a current temperature and a current cell voltage. The processing circuit receives and processes the battery information, and performs: determining whether a battery temperature of any one of the batteries is greater than a designated temperature; if negative, determining whether the current cell voltage of any one of the batteries is lower than a designated voltage, and if affirmative, adjusting the corresponding current battery capacity to generate a reported battery capacity.

Abstract: A battery safety management procedure applicable to a battery safety management system is provided. The battery safety management system includes a controller, storage, and battery. The battery safety management procedure is stored in the storage and executed by the controller to perform steps of: determining whether a power level of the battery is greater than or equal to a power level threshold and determining whether a power storage time is greater than or equal to a time threshold; and performing a discharging procedure when the power level of the battery is greater than or equal to the power level threshold, and the power storage time is greater than or equal to the time threshold. Time control and power level control prevents the battery from being in a prolonged state of high power level to reduce the chance of battery swelling, leaks, abnormalities, and damage, thereby extending battery service life.

Abstract: A charging method includes detecting whether two battery modules are balanced, simultaneously charging the two battery modules by a first charging current when the two battery modules are balanced, and executing a specific charging procedure when the two battery modules are not balanced. The step of executing the specific charging procedure includes charging by the first charging current a first battery module between the two battery modules that is not balanced and disconnecting the other between the two battery modules, and simultaneously charging the two battery modules by a second charging current upon the first battery module reaching balance, wherein the second charging current is less than the first charging current.
