The invention relates to a method, device, equipment and system for determining the charging state of a storage battery, and relates to the technical field of automobiles. The method comprises the following steps: receiving a first charging request message and a second charging request message sent by a BDC, wherein the first charging request message and the second charging request message are two charging request messages sent continuously; determining a target time interval and a target discharge capacity, the target time interval being a time interval between a moment when the first charging request message is received and a moment when the second charging request message is received, and the target discharge capacity being a discharge capacity of the storage battery included in the second charging request message, the difference value is the difference value of the discharge electric quantity of the storage battery included in the first charging request message. And when the target discharge capacity is greater than a preset discharge capacity threshold and the target time interval is less than a first preset duration, determining that the charging state of the storage battery is an abnormal charging state. Therefore, the effectiveness of the storage battery can be judged in the charging process of the storage battery.
本申请涉及一种蓄电池补电状态的确定方法、装置、设备及系统,涉及汽车技术领域。该方法包括接收BDC发送的第一补电请求消息和第二补电请求消息,第一补电请求消息与第二补电请求消息为连续发出的两次补电请求消息。确定目标时间间隔,以及目标放电量,目标时间间隔为接收到第一补电请求消息的时刻与接收到第二补电请求消息的时刻之间的时间间隔,目标放电量为第二补电请求消息中包括的蓄电池的放电电量,与第一补电请求消息中包括的蓄电池的放电电量的差值。在目标放电量大于预设放电量阈值,且目标时间间隔小于第一预设时长的情况下,确定蓄电池的补电状态为异常补电状态。由此,实现了在蓄电池补电过程中,对蓄电池有效性的判断。
