Designing a Reliable Battery Disconnect Unit (BDU)

Quality Components are Essential for Reliable Operation of a Battery Disconnect Unit

Innovative Battery Management System Components from Panasonic

Panasonic is proud to be at the forefront of developing advanced safety and high-quality components for the automotive industry including battery disconnect units (BDU) and Battery Management Systems (BMS). To ensure reliable and efficient operation, Panasonic Industry provides robust EV relays (DC contactors), automotive-grade passive components, and connectors for designing sophisticated control circuitry and precise monitoring systems that the BDU and BMS require. EV relays are responsible for opening and closing the circuit between the battery and the vehicle, while the control circuitry ensures proper sequencing and timing of the disconnection process. The monitoring systems provide real-time feedback on the status of the battery and the disconnection process.
