The invention discloses a fault processing method for an electric automobile crane and the electric automobile crane, the crane comprises a high-voltage system, the high-voltage system comprises a plug-in operation system and a get-on operation system, and the processing method comprises the steps that under the condition that the plug-in operation system and/or the get-on operation system breaks down, the fault level of a fault is determined; determining the current operation condition of the crane; determining a target operation condition of the crane according to the faulted operation system, the current operation condition and the fault grade of the fault; and controlling the crane to be switched from the current operation working condition to the target operation working condition so as to deal with the current fault. And aiming at different working conditions of different systems with faults, the working conditions of the systems are switched based on the fault levels, and the influence of the faults on the use of the whole vehicle is reduced under the condition of ensuring the high-voltage safety of the whole vehicle. And high-voltage safety management of the pure electric automobile crane is realized, so that the viability of the pure electric automobile crane in field operation is exerted to the greatest extent.

    本申请公开了一种用于电动汽车起重机的故障处理方法及电动汽车起重机,起重机包括高压系统,高压系统包括插电作业系统和上车作业系统,处理方法包括:在插电作业系统和/或上车作业系统发生故障的情况下,确定故障的故障等级;确定起重机的当前作业工况;根据发生故障的作业系统、当前作业工况以及故障的故障等级确定起重机的目标作业工况;控制起重机从当前作业工况切换至目标作业工况,以处理当前发生的故障。针对不同发生故障的系统在不同工况下,基于故障等级切换其作业工况,在保证整车高压安全的情况下,降低故障对整车使用的影响。实现纯电动汽车起重机高压安全管理,从而最大程度发挥纯电动汽车起重机野外作业的生存能力。
