充电枪的插拔检测电路及充电枪
By designing a plugging and unplugging detection circuit in the charging gun, different voltage signals are output from the input module and voltage conversion module to detect the plugging and unplugging status, count the number of charging cycles, and transmit data through the control module and communication unit, the problem of the charging gun being unable to autonomously detect the number of plugging and unplugging cycles is solved, enabling timely inspection and maintenance.

AI Technical Summary
Technical Problem
Existing charging guns cannot automatically detect the number of plug-in/plug-out cycles, nor can they automatically read the charging frequency, leading to inconvenience in maintenance.
Method used
A charging gun insertion/removal detection circuit was designed, including an input module and a voltage conversion module. The circuit detects the insertion/removal status of the charging gun by outputting different voltage signals, and counts the number of charging cycles through a control module. The storage unit and communication unit transmit the data to the host computer.
Benefits of technology
This technology enables the charging gun to count the number of plug-in/plug-out cycles, allowing for timely maintenance and ensuring the quality and lifespan of the charging gun.
