6 FAQs about [Function of new energy battery contactor]
What is a battery contactor?
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).
How does a high voltage contactor work?
As a key safety device in new energy vehicles, a high-voltage contactor needs basic functions that are resistant to high voltage, load, shock, strong arc extinguishing, and breaking capacity. An appropriate current is applied to the coil such as using an IC, such as DRV3946, to ensure proper force to drive the contacts for robust operation.
How does a contactor work?
In accordance with the requirements of ISO 6469 and IEC 60664, the contactor ensures galvanic separation between the vehicle electrical system and the battery. During normal operation, the contactors are switched on after a 95% pre-charge of the filter capacity and they have to switch off up to 30 A at 450 V per drive cycle.
Why do contactors have two different electrical circuits inside?
Therefore, contactors have two different electrical circuits inside: one is for actuation and the other one is to carry currents during the switch-on state. There are two main types of contactors: Normally Open (NO) and Normally Closed (NC). A NO contactor does not allow current to flow when the actuation circuit is not powered.
What is the difference between EV contactor and NC contactor?
A NO contactor does not allow current to flow when the actuation circuit is not powered. However, an NC contactor connects the external circuit when the contactor actuation coil is not energized. Therefore, we use EV contactors as NO to switch off the circuit in case of loss of actuation circuit supply.
Should a fuse and main contactor separate the battery system?
Fuse and main contactor must securely separate the battery system from the motor in case of over currents, e.g. in the event of a crash [IV]. The main contactors must keep full functionality, i.e. carry or separate the overcurrent, as long as the fuse has not tripped.
