1000V DC Contactor, because of some problems in material and life, there is a risk of contactor closing age or very sticking. When the 1000V DC Contactor is at the closing age, the output contactor is always in a closed state.

The charging gun head of the charging pile is charged, and there is a danger of personal safety in engineering applications. When the contactor is open and connected, the input is also in a disconnected state. At this time, the charging pile has no way to charge the electric vehicle, which will also cause a waste of resources. In order to solve these problems, most of the industry uses the output contactor of the node to be feedback. This principle is that this type of contactor feedback and receives the current opening and closing status, so as to determine whether the 1000V DC Contactor is abnormal.
There is a prerequisite here, that is, the signal of the feedback node must be correct. If the feedback signal fails, there will still be some risk of misjudgment. And under the same selection parameters, the output cost of the output contactor with feedback node is much higher than that without feedback node. For contactor suppliers, it is also much less. How to use output contactors without feedback nodes can accurately and reliably determine the contactor adhesion.
Failure has always been a problem that plagues the development of this industry. The judgment method of 1000V DC Contactor adhesion failure is to include the following steps before charging:
1. The DC output contactor of the DC charging pile adopts the type without anti-node.
2. When the DC charging gun is plugged into the charging port of the electric vehicle, the physical connection must be intact
3. When charging starts, the charging pile and the DC output contact point are disconnected, and the charging pile and the battery management system establish a handshake communication
4. The charging pile detects the battery voltage U1. If U1 has no voltage, then you can proceed to the next step, otherwise the charging pile will stop charging and send an alarm on the man-machine interface.
5. The charging pile controls the power-on output voltage of the charging module.
6. Compare the battery voltage with the module voltage. If the electronic voltage is not equal to the module voltage, it means that the voltage on both sides of the contactor is equal, and the 1000V DC Contactor is actually in a closed state, indicating that the contactor and the miscellaneous adhesion are abnormally charged. The pile stops charging, and sends a contactor and adhesion warning on the man-machine interface. If the battery voltage is not the same as the module voltage, it proves that the voltage on both sides of the 1000V DC Contactor is not equal, and it is actually in an open state. This is normal and you can proceed to the next step.
