The charging principle of a charging pile

The charging principle of a charging pile

The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with charging plugs for charging electric vehicles. Charging piles generally provide two charging methods: regular charging and fast charging. Users can swipe a specific charging card on the human-machine interaction interface provided by the charging pile to perform corresponding charging operations and print cost data. The display screen of the charging pile can show data such as charging amount, cost, and charging time.

Precautions for Cleaning Photovoltaic Modules

Precautions for Cleaning Photovoltaic Modules

Safety Inspection: Before cleaning the components, check the monitoring records for any abnormal power output entries, analyze whether it may be caused by leakage, and inspect the connection wires and related components for any damage or adhesion. Additionally, use a voltage tester to test the aluminum frame, brackets, and tempered glass surface of the components to eliminate the risk of electric leakage and ensure personal safety.

The role of a solar photovoltaic (PV) controller.

Protecting the battery: Prevent overcharging and over-discharging of the battery to extend its lifespan. When the charging voltage exceeds the protection voltage, the controller will automatically stop charging the battery to prevent overcharging; when the battery voltage falls below the protection voltage, the controller will automatically shut off the output to prevent over-discharging.
