Explaining the mechanism and selection of "safety switches" that support EV and battery storage systems! <Free explanatory column material available>
In recent years, the proliferation of electric vehicles (EVs), hybrid vehicles (HEVs), industrial energy storage systems (ESS), and solar power generation has led to an explosive increase in opportunities to handle direct current (DC) power at high voltage and large current. The important component responsible for the safe and reliable opening and closing control of these DC circuits is the DC contactor, also known as a direct current electromagnetic contactor. DC contactors are essential as "safety switches" that not only control the ON/OFF operation of the system but also instantly disconnect the high-voltage main circuit in the event of overload or abnormal occurrences, ensuring the protection of equipment and the safety of human life. *For detailed content of the column, please refer to the attached PDF.
