Connector design for mechanical locking devices
Main component
Key elements of connector design
Shape and size: Connectors must comply with charging standards such as CCS, CHAdeMO, Tesla, etc., ensure compatibility with different brands and models of electric vehicles, and consider the insertion direction of the plug to facilitate the user to connect and disconnect under different conditions.
Locking mechanism: includes automatic locking and manual release to ensure the security and convenience of the connection.
Material selection: High-strength, wear-resistant materials are used to ensure durability, while highly conductive materials are selected to ensure good current transmission.
Electrical compatibility: The design needs to consider electrical parameters to be compatible with different models of electric vehicles and meet the high currents required for fast charging.
User experience: Design with ease of use and comfort in mind, including intuitive connection cues and ergonomic design.
Connector type
Combo Charging System (CCS) : A widely used DC fast charging standard that combines AC and DC charging capabilities, with two additional DC pins in its connector to support higher charging speeds.
CHAdeMO: An international standard proposed by Japan, designed for Japanese electric vehicles, supports high-power charging, and has a unique locking mechanism.
Tesla Connector: Tesla's exclusive connector design is designed to charge quickly and provide seamless integration with its vehicles, ensuring a productive user experience in the Tesla Supercharge network.
Summary
Connector design is critical to the safety and user experience of DC charging pile charging gun heads, and needs to be continuously optimized to adapt to technological developments and user needs. Future design trends will focus more on versatility, compatibility and ease of use to improve the efficiency and safety of EV charging.
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.
