The embodiment of the invention relates to a state of charge determination method and device, electronic equipment, a medium and a program product. The method comprises the steps of obtaining a first charge state of a battery and starting a coulombmeter when it is determined that the battery management system meets a dormancy condition, obtaining an accumulated charge quantity of the coulombmeter during a dormancy period of the battery management system when it is determined that the battery management system is awakened, and starting the coulombmeter according to the first charge state and the accumulated charge quantity. A second state of charge of the battery is determined. By adopting the method, the estimation error of the state of charge of the lithium iron phosphate battery can be reduced.

    本公开实施例涉及一种荷电状态确定方法、装置、电子设备、介质和程序产品。所述方法包括:在确定电池管理系统满足休眠条件的情况下,获取电池的第一荷电状态并启动库仑计,在确定电池管理系统被唤醒的情况下,获取库仑计在电池管理系统休眠期间的累积电荷量,根据第一荷电状态和累积电荷量,确定电池的第二荷电状态。采用本方法能够减小磷酸铁锂电池荷电状态的估算误差。
