Unlocking Innovation: Reliable Manual Mechanisms in Guchen CCS2 DC Charging Sockets

Customer Inquiry

Do you have a mechanism for manual unlocking? I see that in the technical document, but if the lock cannot be reached outside the vehicle, it may be possible to manually unlock it with the help of a wire etc.?
 

Technical Background

When charging an electric vehicle, the charging gun with a cable is inserted into the charging socket installed on the vehicle. After proper connection, power is supplied to begin charging. Once charging is complete, the charging gun is removed from the charging socket. To prevent accidental disconnection of the charging gun during the charging process, which could result in safety hazards, a locking mechanism is implemented between the charging socket and the charging gun.
Taking CCS2 connector for example, currently, an electronic lock is typically installed on the charging socket. The electronic lock’s latch is controlled via electronic signals to engage or disengage with the lock hole on the CCS2 charging gun, ensuring secure locking and unlocking. However, the operation of the electronic lock relies on electricity, and in the event of a power failure, the electronic lock cannot unlock or lock the latch electronically. Therefore, according to standards such as GB/T 20234.1-2015, it is mandatory to include a manual unlocking mechanism,  a critical solution for instances where the electronic lock becomes inoperable. This article explores the manual unlocking designs of both Guchen front-mounted and rear-mounted CCS2 inlet configurations.
 

Manual Unlocking for Front-Mounted CCS2 Sockets

For front-mounted inlets, the design ensures direct accessibility to the electronic lock.Users can easily reach the unlock lever and manually release the lock by hand.
  This straightforward approach reduces complexity and ensures a seamless user experience while maintaining the reliability of the system.
 

Manual Unlocking for Rear-Mounted CCS2 Sockets

Rear-mounted sockets, often situated in less accessible areas of the vehicle, require an additional mechanism for manual unlocking. To address this, a pull cord is integrated into the design. In scenarios where the electronic locking system is non-functional, users can manually unlock the socket by pulling the cord. This cord is thoughtfully designed for easy operation and durability, resembling standard solutions widely recognized in the industry.
  The inclusion of a pull cord ensures that even in challenging circumstances, such as electronic lock failures or power outages, EV users can rely on a robust manual unlocking method.

The manual unlocking mechanisms for Guchen CCS2 DC charging sockets underscore the commitment to safety and user convenience. Whether through direct access to the unlock lever in front-mounted configurations or the provision of a durable pull cord in rear-mounted setups, these solutions ensure that EV users can address unexpected locking issues effectively. By prioritizing accessible and dependable designs, Guchen sockets continue to support the seamless integration of EVs into everyday life, promoting confidence in the growing EV ecosystem.
