A capacitor pre-charge circuit can be used in electric and hybrid vehicles to decrease the initial surge currents from the battery to the inverter input capacitors upon power-up. The relay is one of the most compact products of its kind available.
Electromechanical switches called pre-charge relays are used to switch high voltage loads.
With the inclusion of capabilities that enable their use in high voltage applications like battery disconnect units (BDU) and charging systems supporting the future of mobility, these relays function in the same way as electromechanical relays.
It has a highly effective magnetic circuit that aids in putting out magnetic arcs that could harm the contact surface.
The Global EV Precharge Relay 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.
Omron is providing the G9EJ-1 relay, which is specifically made for the task, for circumstances when this is accomplished using a resistor and relay. It is 30 x 27 x 31mm and weighs about 50g, and it is rated for 25A at 400Vdc. The bigger 200A at 400Vdc G9EC (11W coil), which switches the motor circuit once pre-charge is finished, is likewise part of Omron’s selection of power relays.
The NEW small Durakool DG17M pre-charge relay solution for high voltage advanced automotive hybrid and electric cars is offered by American Electronic Components Incorporated (AEC). Only 26.5 x 21.5 x 21.5mm in size, this highly efficient, reasonably priced device for electric mobility vehicles is designed to permit switching loads of up to 10A at 450VDC.
