The invention relates to the technical field of overcharging, and discloses an electric vehicle overcharging system and a control method.A battery charging parameter monitoring module obtains time-varying data of charging voltage and charging current of each single battery in the overcharging process in real time, and a battery temperature parameter monitoring module monitors temperature parameters of the battery; the method comprises the following steps of: acquiring temperature change data of each single battery along with time in an overcharging process in real time, then analyzing the data of the single batteries, judging whether the single batteries have faults or not, if not, analyzing whether the single batteries have potential faults or not in a charging process, eliminating charging risks of each single battery, and then determining whether the single batteries have the potential faults or not. And analyzing the battery pack data, judging whether the battery pack has a fault or not, and if not, analyzing whether the battery pack has a potential fault or not in the charging process, so that quick charging is ensured, and meanwhile, the fault in the charging process of the battery is also avoided.
本发明涉及超充技术领域,公开了一种电动汽车超充系统及控制方法,本发明通过电池充电参数监测模块实时获取超充过程中各个单体电池的充电电压和充电电流随时间变化数据,通过电池温度参数监测模块,实时获取超充过程中各个单体电池的温度随时间变化数据,然后,对单体电池数据进行分析,判断单体电池是否出现故障,若未出现故障,则分析单体电池在充电过程中是否出现潜在故障,排除各个单体电池的充电风险,然后,对组电池数据进行分析,判断组电池是否出现故障,若未出现故障,则分析组电池在充电过程中是否出现潜在故障,保证快速充电的同时,也避免电池充电过程中出现故障。
