Device positive and negative anodes processed, if causing the controller positive and negative anodes of five in one and battery plus-negative plate to be reversely connected, battery due to the operation error of people
Control system BMS can not have found, corresponding relay close commands can still be issued, after the completion of closure, by motor control
Device issue failure order after be given to VCU, then VCU is transmitted to after BMS system, be likely to discovery fault message, still, at this time by
In positive and negative reversal connection, the IGBT of pre-charge resistance inside controller, discharge resistance and electric machine controller may cause
Damage, causes permanent fault, causes the paralysis of whole system.
According to problem above, a kind of device is needed now, the reversal connection of five in one controller external input, BMS system can occurring
System between power input positive and negative anodes without detecting before being closed internal heavy-current relay, when being reversely connected, rapidly by event
Barrier order passes to BMS system, prevents the generation of failure.
Technical problem as above exists in the prior art, the present inventor combines years of researches experience, proposes a kind of new energy
Source automobile five in one controller counnter attack connection device.
