Electric vehicle charging guns serve as crucial tools for powering electric vehicles. These guns essentially serve as the intermediary link between the charging infrastructure and the electric vehicle's rechargeable battery. To ensure a consistent and reliable connection between the charging pile and the gun, mandatory standards are imposed by the state, binding all charging pile manufacturers and electric vehicle producers to adhere to these specifications.
The charging gun is segmented into 7 joints for AC piles and 9 joints for DC piles. Each joint signifies a distinct power source or control signal, with specific regulations outlined in the national standards.
At the heart of a portable car charging gun lies the control box, a seemingly inconspicuous element housing pivotal technology. Within this control box lie several components tied to invention patents, highlighting its significance in the charging system.
