All sizable electric vehicles, including cars, trucks, boats, and rail locomotives, use electric vehicle (EV) contactors as the primary contactors in their electric vehicle driving circuits.
The primary contactor’s job is to open under a potential short circuit load (up to 3,000A or more), protecting the motor drive electronics as much as possible during normal operation of the car and in an accident when a fire could start from a potentially dangerous, high current short circuit.
The pre-charge contactor, having served its purpose, opens when the primary contactors close, disconnecting the resistor and preventing excessive heat and power waste.
The car is stationary and the filter capacitors are fully charged at the moment the main contactors close, allowing the vehicle to move.
The Global EV Main Contactor Market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Main Contactor EVC 250, a Texas Instruments high-voltage contactor for hybrid and battery-electric cars (HEV, PHEV, BEV). The energy storage system for hybrid and electric vehicles must be safeguarded against thermal overload just like the petrol tank in a regular car.
Therefore, fuse and relay combinations are employed at the junction between the traction battery and the electrical board net to prevent galvanic separation after the vehicle is turned off or in the event of a failure. The EVC 250 was especially created with the needs of this application in mind.
