本发明的实施方式
在相关技术的汽车充电过程中，不论是有线充电方式还是无线充电方式，一个充电桩只能检测到本充电桩的状态，如本充电桩的输出电压、电流等，多个充电桩之间并无信息交互，也没有全局性的后台管理支撑。汽车只能检测到自身的状态，如蓄电池电压。而实际上整套充电系统需要关心的参数不仅仅这是些，例如市电的参数波动、充电电路中每个子模块的输入与输出、每个部件温度对充电过程的影响等，无法全面掌握和了解。这种方式下，一旦出现充电异常，很难判断问题出在哪里，造成故障排查难度大，业务中断时间长，设备有效利用率低等情况，整体充电过程中的用户感受降低，充电桩运营商在维护和管理方面也会增加成本。
因此，相关技术的汽车充电过程中无法对整个充电系统进行监控，进而导致充电异常时无法快速判断故障原因，使得业务中断时间长的问题。
