KIA Niro: Safety Plug Description and operation
Kia Niro - First generation - (DE) (2017-2022) - Service and Repair Manual / Hybrid Control System / Main/ Sub High Voltage Battery / Safety Plug Description and operation
Description
Safety Plug is installed on the rear side of the high voltage battery and it
can mechanically shut the
high voltage circuit off when servicing the high voltage system. (i.e. High
Voltage Battery, Power
Relay Assembly, HPCU, BMS ECU, Hybrid Drive Motor, Inverter, HSG, LDC, Power
Cable, etc.)
It includes a fuse in order to prevent the high voltage system from overcurrent
