Durability Testing of BDU

Durability Testing of BDU

Simulating the long-term current ripple durability of the high-voltage box and the long-term rapid disconnection of the high-voltage box pre charging relay under the operating conditions of the entire vehicle, it was found that the insulation resistance of the high-voltage box decreased, the impedance increased, and the pre charging resistor generated severe heat;
Pack Current Ripple lnjection

Pack Current Ripple lnjection

The battery pack was injected with current ripple, but no resonance point was generated but there was a noticeable whistling sound. Subsequently, the BDU was injected with current ripple, and it was found that the 18kHz accessory had resonance, and a buzzing sound began to appear at 2kHz, with decibels increasing with the ripple frequency;
