Contact Spring of Dc charging pile
Main component
Concept:
The Contact Spring of DC charging pile usually refers to a key component in the DC contactor, which plays a crucial role in the charging pile. Dc contactor is an electrical component used for circuit control, mainly used to cut off or connect the path of DC current.
Function:
The role of Contact Spring in DC charging pile is mainly reflected in the following aspects:
Current connection and disconnection control: Contact Spring is used for current connection and disconnection control with the battery charging system to ensure that electric vehicles can be charged safely and efficiently.
Protect the charging system: by disconnecting the circuit to prevent equipment damage caused by overcurrent or overvoltage, especially in the charging process, if there is a short circuit or other failure, Contact Spring can quickly cut off the circuit to ensure the safety of the charging pile and electric vehicle battery.
Working Principle:
The working principle of Contact Spring is closely related to its role as a control element:
Power on: When the charging pile is connected to the electric vehicle, the electromagnetic coil of the DC contactor will receive the control signal. Under the action of the electromagnetic force, the contact of the contactor is closed, and the current can flow into the battery system through the contactor.
Charging process control: During the charging process, the Contact Spring will keep the state closed according to the change of charging current and voltage until the end of the charging process. At this time, the contactor contacts will remain stable to ensure the smooth charging of the battery.
Disconnect the power supply: When charging is complete or failure occurs, Contact Spring will automatically disconnect the circuit and cut off the power supply. This automatic disconnect function can effectively avoid safety hazards such as overcharging and overheating.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
