This work presents a high-voltage (HV) Transceiver used in Battery Interconnect Module (BIM) for electrical vehicle (EV) Battery Management System (BMS). To realize a HV (300 ~ 400 Volts) BMS for EVs, the HV Transceiver in the BMS shall be fabricated using an advanced HV semiconductor process to sustain high voltage drop of battery modules. Besides, the proposed HV Transceiver is better carried out without using any isolator. The proposed HV Transceiver is measured and proved to transmit and receive data with a -32 ~ +32V common mode voltage.
