Release mechanism in mechanical locking device
In the design of charging piles and electric vehicle (EV) charging interfaces, the release mechanism is an important part of ensuring that the charging gun can be safely and quickly disconnected from the EV. The reasonable release mechanism not only improves the user's operating experience, but also ensures the safety when disconnecting and charging, avoiding accidents in the state of high voltage and high current. Therefore, the design of efficient and safe release mechanism is the key link in the design of charging system.
Main component
concept
The release mechanism means that after the charging gun is connected to the electric vehicle interface, they are separated quickly and safely by some method or device to complete the charging process and prepare for the next charge. The release mechanism is designed to ensure that no electrical failure or safety incident will occur when disconnected.
Working Principle
The release mechanism usually needs to complete the process from the charging state to the disconnection state when the user or the device issues an operation instruction.
This includes the following steps:
Detection status: The charging pile monitors the connection status between the charging gun and the electric vehicle through the electronic control system.
Active unlock: In the case of ensuring safety, the electronic control system issues instructions to trigger the release mechanism.
Physical separation: The release mechanism separates the charging gun from the interface, either mechanically or electrically.
Summary
The release mechanism plays a crucial role in the design of charging interface of charging pile and electric vehicle. A reasonably designed release mechanism can improve the charging experience and efficiency on the premise of ensuring user safety. In the future design, mechanical reliability, user friendliness and corresponding intelligent control technology will be the key elements to improve the overall performance of charging equipment. Continuing to advance automation and digitalization trends will make the charging experience smoother and more in line with the needs of future mobility.
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.
