Bender GmbH & Co. KG is a globally active medium-sized family company and leading provider of top-class electrical safety products and solutions. The basic aim is to be able to charge electric vehicles from virtually any socket. This means different networks and protective measures can come together during the charging process. This requires careful coordination and implementation of all measures in order to guarantee comprehensive electrical safety for the user here too. In the vehicle, there are various voltages which require careful coordination of protective measures to control them. Insulation faults in the Class B voltage system (on-board network) caused by, for example, contamination, humidity, faulty connections, etc. must be avoided or detected and remedied. Bender devices make sure that electric vehicles (EV) can be charged safely and reliably – in accordance with the normative requirements for the charging process.
