Pre-charge circuitry and contactor closing/opening is controlled independently for each channel to allow for connecting and disconnecting the individual loads. The Vanner High Voltage Distribution Module (commonly referred to as HVDM in this document) is an efficient and highly reliable method of distributing high voltage, 400 to 800VDC, derived from a traction battery system. The high voltage is distributed to two fused output channels via high voltage. The High Voltage Power Box combines the functionality of an Onboard Charger (OBC), a DC/DC converter and a PDU (Power Distribution Unit). The OBC is the interface between the car and the public grid. It converts the energy from the network grid AC (Alternative Current) source to DC (Direct Current). Our HV PDUs are characterized by a compact and robust design that enables flexible configuration options and the integration of a wide range of control functions. They ensure safe, reliable, and efficient distribution of high-voltage power across vehicle systems and industrial applications. Our portfolio of HV PDUs enables controlled power flow. Our high voltage wire processing solutions give you the power needed to terminate high voltage connectors in a flexible, affordable and compact bench-top solution.
