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.
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.
Here are key steps to consider when selecting an HVDC contactor: 1. Operating Voltage: Ensure that the rated operating voltage of the DC contactor meets the voltage requirements of the system. 2. Operating Current: Select a DC contactor with sufficient carrying capacity according to the current load demand of the system. 3. Short-circuit Current:
High Voltage DC Contactor is an electrical control device used in an automated control circuit. It is actually an “intelligent control switch” that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic regulation, safety protection and conversion circuit in the circuit.
Most of the contactor manufacturers share necessary information in datasheets. Thus, a wise approach would be making a comparison table to cover basic specifications like thermal and mechanical initially. After pre-selection based on datasheet values, we should consider system specifications.
Because the maximum breaking current is 3000 A according to the above table, the incomplete short circuit can be safely handled by contactor. Therefore, giving a 15% safety margin, the minimum breaking current of the fuse must be 2550A at maximum. Temperature affects contactor selection significantly.
