Modern automotive battery management systems (BMS) compete with challenging performance and safety requirements and need to monitor a large amount of battery parameters. In this paper, we propose power line communications (PLC) for high voltage (HV) traction batteries to reduce the BMS wiring effort.
The base station power cabinet is a key equipment ensuring continuous power supply to base station devices, with LLVD (Load Low Voltage Disconnect) and BLVD (Battery Low Voltage Disconnect) being two important protection mechanisms in the power cabinet.
The HVIL circuitry alerts the battery management system (BMS) of an open connection and allows the BMS to immediately shut off the high voltage power to prevent arcing during disconnect. This also protects against a floating high voltage for a loose wire.
The HV battery supplies the electric power train and the DC-link capacitor . The BMU is connected to the 12 V on-board power supply and the control area network (CAN) of the EV.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
