CONSTRUCTION
The hybrid battery junction block assembly consists of System Main Relays (SMRs), a precharge resistor and a HV battery current sensor.
The SMRs consist of the SMRB (+), SMRG (-) and SMRP (precharge).
A large amount of current is generated due to the connection of the power cables. As a result, SMRP and SMRB (+) are turned on first to let the current enter the circuit in a controlled manner through the precharge resistor to protect the circuit. After that, the SMRG is turned on and SMRP is turned off.
