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; Pack Voltage Ripple Injection Inject voltage ripple into the battery pack, and the working state does not change due to the superimposed sine voltage; But the impact of voltage ripple injection varies in different states; Self-Generated Ripple of Pack and HV System We have a complete set of ripple testing solutions that can collect and analyze the ripples generated during the driving of the vehicle or the charging and discharging process of the battery pack AC Self-Heating of Pack and Vehicle By using high-voltage ripple devices for AC self heating of packs and the entire vehicle, the heating efficiency can be significantly improved, thereby enhancing the charging rate of new energy vehicles in low-temperature environments;
