左图是应用示意图，红色虚线框内是该产品原理图。它集成一个承载大电流的熔断体TCO1，发热片R1&R2和温度保险丝TCO2，隔离的温度保险丝TCO3。 BMS监测电池异常时，输出信号触发MOS管导通，发热片R1和R2开始加热。温度保险丝TCO1受热后断开，永久性切断主回路。随后温度保险丝TCO2断开切断发热片。与此同时，温度保险丝TCO3也受热断开，产生一个独立开关信号给BMS。 The left figure is the principle and application note. Inside the red square is ITCO, which integrated TCO1, R1&R2,TCO2 and TCO3. When the BMS detect the abnormal behavior of EV battery, The BMS output a signal to activate the MOSFET. Then the heater R1&R2 is power on and heat. The thermal cutoff(TCO1) blow and disconnect the circuit. After that, The TCO2 blow and disconnect the heater, the TCO3 blow at the same time and output a remote signal to BMS. |
