The invention discloses an electric automobile charging early warning out-of-control protection device and method. The device comprises a charging control box arranged on a charging loop between a charging pile and an automobile charging port. The control box body is provided with indicating lamps in three colors so as to indicate the corresponding state of thermal runaway. The control box obtains the charging electric quantity of the electric vehicle in the rapid charging process, the temperature sequence of each battery module under the dynamic power and the SOC of the battery in real time, and obtains parameters such as the output power, the temperature and the charging interface temperature of the charging pile in the rapid charging process in real time. And the lightening states of the three color indicating lamps are controlled according to the parameters obtained through monitoring. The device has the advantages that the states of the electric vehicle and the charging pile in the charging process can be monitored, an alarm can be given to remind an operator when abnormity occurs, the device can also isolate the linkage effect on other equipment when the electric vehicle or the charging pile spontaneously combusts, and the problems proposed in the background technology are intelligently solved.

    本发明公开了一种电动汽车充电预警失控保护装置及方法,包括设置在充电桩和汽车充电口之间充电回路上的充电控制箱;所述控制箱体上设置有三种颜色指示灯以指示热失控的对应状态;所述控制箱实时获取快速充电过程电动汽车的充电电量、动态功率下各电池模块的温度序列以及电池的SOC,实时获取快速充电过程充电桩的输出功率、温度,充电接口温度等参数;根据监控获取的参数来控制三种颜色指示灯的点亮状态。本发明的优点在于:能够监控充电过程电动汽车和充电桩的状态,当出现异常时会发出警报提醒操作人员,此装置也能够隔绝电动汽车或者充电桩自燃时对其他设备的连锁效应,智能化的解决背景技术中提出的问题。
