Modeling and Analysis of a Battery Management System for Electrical Vehicles

The power distribution unit (PDU) is an essential part of the high-voltage electrical distribution system on an electric vehicle system. PDU is involved in both the charging and driving modes of a vehicle. PDUs can fail in several ways depending on the circumstances. Vehicle usage can increase the risk of PDU failure because bus bars, fuses, and HV contactors can get hot. A high voltage power source and a high voltage/current load bank are needed to replicate the real-world vehicle scenario on a bench level. With the resistive load bank, there is a 100% loss of power, or energy. set up a test facility with an EV DC fast charger and battery emulator to prevent the power loss (by 85%). This test configuration helps to determine the likely source of the problem and solve it at the bench level by simulating the actual state of the vehicle on the junction box.
