The future belongs to innovative electric and hybrid vehicles. However, they also engender new problems because of the high, potentially fatal currents required. In order to prevent electric shocks during accidents, fires and short circuits, the electrical energy must be safely distributed. This places particularly high demands on the wiring and its screening. HUBER+SUHNER offers customer-specific, high-voltage distribution solutions for vehicles of this kind.
Distributing the electrical energy safely between the storage devices and the drive assemblies is only one of the challenges that electric and hybrid vehicles pose. Further constraints such as restricted space, light weight and positioning in the vehicle increase the demands. Customised solutions are generally required. This is where HUBER+SUHNER comes into its own. The team supports customers from the planning and prototype stage right through to series production.
High-voltage distribution systems and adapter plates
The specially-developed High Voltage Distribution Units (HVDU) distribute energy between the battery, generator, charger and other secondary assemblies in electric vehicles. They are designed to customer specifications and delivered with assembled wiring. A special feature here is the cable routing in the distribution station. The cables are fed directly into the box in an extremely compact manner through a connection plate. HUBER+SUHNER also develops adapter plates for hybrid vehicles. The optimum transfer of energy is a decisive factor for the efficiency of hybrid vehicles. The customized add-on components for power electronics provide for space-saving and safe distribution of energy between the vehicle battery and motor or generator.
Connection system catalogue
While the adapter plates and HVDUs require customized solutions, the innovative, shielded RADOX® Automotive Connection System (RACS) can be purchased directly from the catalogue. It connects the HVDU and high-voltage assemblies safely and efficiently by means of an innovative direct connection in extremely confined spaces. RACS is also supplied as a customer-specific assembly with RADOX cables and a connection plate in a one, two or three-pin versions. As HUBER+SUHNER specialises in customised solutions, the experienced team is often confronted with tricky special cases, whether for on-road or off-road vehicles.
