New Mobility - DC under control
For tomorrow’s mobility solutions
Powerful lithium-ion batteries are currently the most common battery type used for electromobility. Schaltbau’s DC contactors play a key role within the safety circuit: They reliably disconnect in case of failure and therefore ensure galvanic isolation between the battery and the rest of the vehicle’s electrical system.
DC interlock contactors C801 with innovative interlocking system
Interlock contactors enable 800-volt electric vehicles to be charged quickly and easily, even at 400-volt charging stations. For this purpose, DC contactors of the C801 series configure two 400 V battery banks during the charging process so that they are charged in parallel. During operation, a patented mechanical interlock of the main contact system ensures extreme shock resistance up to 120g/20ms. This prevents the possibility of a short circuit of both battery banks, e.g. as a result of a vehicle crash.
DC contactors in battery test stations
The development of new batteries and battery management systems requires exhaustive tests and validations – particularly with regard to safe functionality. Battery systems for electric vehicles are tested for the purpose of quality assurance at battery test stations at the end of the production line. Schaltbau contactors must switch currents of up to 480 A safely when charging and discharging the battery.
High-voltage contactors for the mobility of tomorrow
High-power battery systems are used in vehicle with electric drives. DC contactors from Schaltbau play a key role here in the BDU (Battery Disconnect Unit). It isolates the high-voltage battery from the high-voltage network along with all the electrical components of the vehicle in the event of danger.
