Precautions for using AC charging connection devices: After the charging pile is powered on, when the wiring is correct, the power indicator light will illuminate. The charging current indicator lights for 1 to 30A will illuminate, along with the first constant charging and second constant charging indicator lights. It is recommended to charge for more than 10 hours when the battery is in a depleted state. When the battery voltage is low, control the current to charge at a relatively constant rate. When the battery voltage reaches a certain level and is close to full, ensure that the battery voltage rises slowly at a certain speed to guarantee a full charge. Therefore, the main charging methods for electric vehicle batteries can be summarized as constant current charging, constant voltage charging, and pulse fast charging. Depending on the specific situation, one charging method or a combination of several methods can be chosen. Modern intelligent battery chargers can be configured with different charging methods.
There are several key points to pay special attention to when using AC charging connection devices. Before each charging session, I make it a habit to walk around the vehicle to inspect the surroundings. The charging gun plug must be kept dry - avoid water splashing onto the interface during rainy days. The operation sequence is crucial: first unlock the vehicle port before inserting the gun, and remember to press the switch button until the indicator turns green when removing it. Don't randomly pull the cable during charging - I've seen people trip and nearly cause accidents. After charging completes, don't rush to pull forcefully; wait for the system to indicate charging is finished before disconnecting. Also avoid having the cable pressed under wheels or pinched by doors - my neighbor once crushed the cable and wasted money on repairs. It's best to inspect the gun head and interface for any burn marks every six months for safe usage.
