The high-voltage components are mainly three electric parts, including power battery, driving motor and high-voltage distribution box (PDU) of electric control system. For batteries, there are DC contactors, high-voltage relays, precharge resistors, etc. for motors, there are stators, rotors, current sensors, AC contactors, etc. for electric control systems, there are on-board chargers, PTC, electric compressors, high-voltage line contacts, OBC / DC, DC two in one controllers, etc. Among them, the high-voltage suitable distribution box used in new energy vehicles (pure electric) inclu |
