Battery management system and method for a bucking and discharging to battery based on a safety of battery storage

Abstract

This disclosure provides a battery management system. The battery management system comprises a buck converter, a discharge loop, and a microprocessor. The microprocessor comprises a battery status monitoring circuit, a timer, and a controller. When the status of the battery is in a static state, the timer starts counting a time. If the time counted by the timer is greater than or equal to a time threshold, the controller controls that the buck converter executes a bucking to an output voltage of the battery, and then controls that the discharge loop executes a discharging to the battery. Accordingly, when the status of the battery is in a static state, the battery capacity can be discharged to a safe value moderately, so that the safety of the long-storage of the battery can be ensured, and the life of the battery can be prolonged.
