Powerful electric vehicles usually use two battery banks, each with 400 volts, interconnected to form an 800 volt system in the drive train. This ensures high performance while driving. Only a few 800 volt high-performance charging stations are available. However, interlock contactors enable 800 volt electric vehicles to charge quickly and easily at 400 volt charging stations. For this purpose, interlock contactors of the C801 series configure both battery banks during the charging process so that they are charged in parallel. The robust, durable contactors do not require inert gas and have a high current-carrying capacity.
A patented mechanical interlock system ensures extreme shock resistance during normal operation. This prevents uncontrolled closing of the main contacts and the possibility of a short circuit of both battery units in the event of a collision.
