In a battery the contactors are a switch that can be operated by the control system. They are essentially a relay. These contactors are designed to be able to break (switch off) the circuit under full load (maximum current and at maximum system voltage). There are two main types of contactors: Normally Open (NO) and Normally Closed (NC).
Main contactors, pre-charge contactors, and DC charge contactors are mostly located in the battery junction box (or battery disconnect unit). AC charge contactors are likely to be placed in the battery power distribution unit which is adjacent to the onboard charger.
The main positive contactor is between the positive battery pole and the traction inverter while the main negative contactor is between the negative battery pole and the traction inverter. Both these contactors are required for safety robustness.
For battery EVs, another pair of DC fast charge contactors is inserted to establish a connection between the traction battery and the DC fast-charge equipment. The DC fast charging is essential for long distance driving and large battery EV fleets.
They are essentially a relay. These contactors are designed to be able to break (switch off) the circuit under full load (maximum current and at maximum system voltage). When the battery pack contactors are closed onto a motor and inverter there will be an inrush of current into the inverter capacitor.
Request the S neg contactor to close. Measure the voltage across the S neg contactor, from the positive terminal of the battery to the negative terminal of the DC link. If the measured voltage equals the battery voltage, the contactor is closed with no indication of being stuck open.
