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

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.

The main functions of solar photovoltaic inverters include:

The main function of a solar photovoltaic inverter is to convert the direct current (DC) generated by photovoltaic modules into alternating current (AC) for household or commercial use, allowing the electricity to be smoothly connected to the grid and providing a stable power supply for various electrical devices. The photovoltaic inverter plays a crucial role in solar power generation systems.

What are the control mainboards for new energy vehicles?

BMS (Battery Management System Controller): BMS is the core component for protection and management in the power battery system. It is mainly responsible for monitoring the state of the battery, preventing overcharging and over-discharging, and extending the battery's lifespan. BMS controls the charging and discharging of the power battery pack through contactors and reports the substrate parameters and fault information of the power battery system to the Vehicle Control Unit (VCU).

The working principle of a solar water heater is based on the conversion of solar energy into thermal energy. It typically consists of a solar collector, a storage tank, and a circulation system. 1. **Solar Collector**: The solar collector absorbs sunlight and converts it into heat. It usually contains a dark-colored surface that maximizes heat absorption. 2. **Heat Transfer**: The heat absorbed by the collector is transferred to a fluid (usually water or a heat transfer fluid) that circulates through the system. 3. **Storage Tank**: The heated fluid is then directed to a storage tank where the hot water is stored for use. 4. **Circulation System**: A pump may be used to circulate the fluid between the collector and the storage tank, ensuring efficient heat transfer. 5. **Usage**: When hot water is needed, it is drawn from the storage tank for various applications such as bathing, cleaning, or heating. Overall, solar water heaters are an efficient and eco-friendly way to harness solar energy for heating water.

The working principle of a solar water heater is mainly based on the process of photothermal conversion, which utilizes solar energy collection devices to convert solar radiation into thermal energy, thereby heating water and storing it for use.

Photovoltaic Module - EVA

The material used for encapsulating crystalline silicon solar cells is EVA, which is a copolymer of ethylene and vinyl acetate. EVA is a thermosetting hot melt adhesive that is non-adhesive at room temperature for ease of handling. Under certain conditions of heat and pressure, it undergoes melting adhesion and cross-linking curing, becoming completely transparent. Long-term practice has proven that compared to other materials, EVA has achieved quite satisfactory results in solar cell encapsulation and outdoor use.
