标题: High Voltage DC Relay for New Energy Vehicles: Key Component for Safety and Performance The High Voltage Direct Current (HVDC) relay plays a pivotal role in the rapidly evolving field of new energy vehicles (NEVs), including electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). As these vehicles increasingly rely on high-voltage battery systems to deliver efficient propulsion and auxiliary power, the HVDC relay ensures both operational safety and system reliability. Its function extends beyond mere switching; it serves as a critical guardian of the vehicle’s electrical integrity and the occupants’ safety.
