This charging pile with battery detection and battery repair functions converts the input AC power into DC power suitable for battery charging through the charging module. The current is transmitted through the wires to charge the electric vehicle battery, realizing the transmission and conversion of electric energy to meet the battery charging needs. During the charging process or when performing a separate test, the internal resistance detection module obtains the battery's electrical signal through the adapter cable, detects the battery's internal resistance and other parameters, and evaluates the battery's health status by analyzing the changes in the battery's internal resistance, such as whether the battery has plate sulfation, capacity attenuation and other problems. The detection data is then transmitted to the relevant control system through the adapter cable to provide a basis for battery repair.

[0015] 2. The charging pile with battery detection and battery repair functions obtains the electrical signals required for work through the pulse repair module according to the instructions of the control system through the adapter cable. The pulse repair module generates a specific pulse signal, which is transmitted to the battery through the adapter cable and wires to repair the battery.

[0016] 3. The charging pile with battery detection and battery repair functions accelerates the flow of air inside the pile body after the cooling fan at the top of the pile body is started, and discharges the heat generated inside through the exhaust port on the side wall of the pile body, thereby realizing active heat dissipation and reducing the temperature inside the pile body.

[0018] 5. The charging pile with battery detection and battery repair functions is equipped with a slider that slides in the slide groove on the inner wall of the support plate. The support rod at the bottom of the slider extends to the outside of the support plate.
