在预置时间延迟后，根据所述目标电压与预期标准电压进行对比，判断所述快充继电器是否故障。
在本申请实施例中，考虑到所述快充继电器上报所述目标电压需要消耗一定时间，为了防止电池管理系统误报故障，可以设置一定的预置时间，在预置时间后对所述目标电压进行延迟对比判断，从而避免了由于上报所述目标电压获取延迟可能导致的误报。
示例的，当电池管理系统发出快充继电器驱动电平后，20ms内快充继电器可闭合，然后电压采样电路副边的单片机可采集到电压，这个过程需要5ms，25ms内通过串口发送给DPS(Digital Signal Processing，数字信号处理芯片)，然后充电机在20ms-40ms内上报所述目标电压，由于具体时间难以计算，为了保证电池管理系统诊断的准确性，可以设置在200ms的预置时间延迟后开启诊断快充继电器是否处于断开状态。
进一步的，当所述配电盒内仅包括快充正继电器时，参照步骤301b，步骤302可以通过以下示例实现，
所述电池管理系统接收充电机上报的所述目标电压，将所述目标电压与所述预期标准电压根据下表2进行对比，
表2
步骤303，若无故障，根据判断结果输出检测报告。
在本申请实施例中，所述电池管理系统通过将所述目标电压与所述预期标准电压进行对比进行诊断得到判断结果，若判断结果为正常，则所述电池管理系统输出所述快充继电器粘连正常的检测报告。
进一步的，所述方法可以还包括：
步骤304，若故障，关闭电路并根据判断结果输出检测报告。
在本申请实施例中，若所述电池管理系统通过诊断得到的判断结果中出现故障，则根据判断结果，输出包含有具体故障类型的检测报告，并关闭电路防止出现人身与财产损失。
