High Voltage Connectors Handle up to 450A in Electric Vehicles

By Nick Flaherty, Contributing Editor

Rosenberger GmbH, based in Tittmoning, Germany, has launched a new series of high-voltage connector systems developed especially for power transmission in electric and hybrid vehicles.

The harmonized system consists of Rosenberger HV connectors for current loads up to 50 A and 450 A for cable diameters from 2 x 4 mm² to 120 mm² as well as power distribution units for customer-specific assemblies. A generation of 48V connectors will be available on request.

The HVR300 connector system is currently in the development phase and is available on request. It has a maximum current carrying capacity of 320A combined with minimal space requirements. The product portfolio includes a 2-pole angled coupler for shielded cables and a cable cross section of 70 mm² along with the corresponding header. A cross section of 50 mm² is available on request. The lever locking mechanism is secured with an additional slider (CPA – Connector Position Assurance) to prevent accidental unmating.

The HVR420 connectors have the highest current carrying capacity at 420A even in the 95 mm² variant. With the largest cable cross section of 120 mm², current intensities of up to 450A can be achieved at a temperature of 85°C. The additional slide locking mechanism prevents the connection from unmating accidentally in applications such as the supercharging of electric vehicle batteries with up to 450 kWh.
