Pre-charge control

close

Pre-charge circuits are often used in electric vehicles (EVs) such as battery management systems and onboard chargers. In EVs, high voltage (HV) positive and negative contactors are used in this system to act as an emergency disconnect when the regulator fails. Without a pre-charge circuit, welding can occur within the contactor as it closes and there could be a brief arc resulting in pitting.
