The invention discloses a multi-pile charging fault diagnosis method and device and a vehicle. The multi-pile charging fault diagnosis method comprises the steps that system information of a power battery, state information of the whole vehicle and charging information of at least two charging piles are obtained; according to the system information, the state information and the charging information, charging fault information of the power battery, fault information of the whole vehicle and pile end fault information of the charging pile are determined; the fault degree of the multi-pile charging process is judged according to the charging fault information, the fault information and the pile end faults; and controlling the charging process of the charging pile based on different fault degrees. According to the fault diagnosis method provided by the invention, processing can be carried out when a fault occurs in the process that the multiple charging piles charge the automobile at the same time, the battery protection and charging efficiency in the multi-pile charging process is improved, and the efficiency and safety of the automobile in the multi-pile charging process are ensured.

    本发明公开了一种多桩充电的故障诊断方法、装置及车辆,包括:获取动力电池的系统信息、整车的状态信息和至少两个充电桩的充电信息;根据系统信息、状态信息和充电信息分别确定动力电池的充电故障信息、整车的故障信息和充电桩的桩端故障信息;根据充电故障信息、故障信息和桩端故障判断多桩充电过程的故障程度;基于不同的故障程度控制充电桩的充电进程。本发明提供的故障诊断方法可以在多个充电桩同时为汽车充电过程中发生故障时进行处理,提高了多桩充电过程中对电池的保护及充电效率,保证了汽车在多桩充电过程中的效率和安全性。
