Battery Disconnect Unit

The Battery Disconnect Unit (BDU) ensures the safe and reliable connection of the high-voltage battery with other high-voltage components in the vehicle, such as the onboard charger or the traction inverter. It also helps determine the state of charge of the high-voltage battery and disconnects the battery from the rest of the vehicle in safety-critical situations. Thanks to many years of experience in injection molding, stamping, and mechatronic system design, Swoboda offers customized BDU solutions for automotive applications.
