In accordance with the requirements of ISO 6469 and IEC 60664, the contactor ensures galvanic separation between the vehicle electrical system and the battery. During normal operation, the contactors are switched on after a 95% pre-charge of the filter capacity and they have to switch off up to 30 A at 450 V per drive cycle.
DC contactors play a key role in the battery management system. They are used to control the connection and disconnection of the battery pack, to realize the charging and discharging management and protection of the battery, and to ensure the safe operation of the battery pack.
Therefore, for galvanic separation after turning off the vehicle or in the event of a failure, fuse and relay combinations are used at the interface between the traction battery and the electrical board net. In this article, the EVC 250 main contactor (EVC 250) is presented.
The main contactors must keep full functionality, i.e. carry or separate the overcurrent, as long as the fuse has not tripped. The open contactors must ensure a sufficient insulation resistance between the energy storage system and the vehicle after a switch-off under fault conditions.
Consider factors such as the rated voltage of the coil drive power supply, the stability of the power supply, and the power supplied to match the coil control requirements of the DC contactor. DC contactors are widely used in electric vehicles such as electric cars, electric bicycles and electric motorcycles.
Based on the typical fuse characteristic as shown above and assuming a system response time of 200 ms, the contactor must be able to carry a current of up to 6,000 A for 5 ms or 2,000 A for 20 ms without damage and to switch off a current of 2,000 A. 2.2. Service conditions / ambient requirements
