pre magnetic contactor in EV vocabulary is the precharge (pre-charging) contactor: a small sealed HV DC contactor that closes first through a precharge path so the DC-link capacitance charges under controlled current, and only then does the main contactor close \u2014 limiting inrush that would otherwise erode or weld main contacts, with device choices audited against published HEV series fields. This explainer is for EV powertrain and BMS engineers who inherited the term from supplier lists and need it mapped onto real precharge design.
