LED screen

LED screens, a type of display made using LED technology, are widely used in various fields due to their vivid colors, high brightness, wide viewing angles, and energy-saving advantages. These displays typically consist of multiple red, green, and blue LED beads, and by controlling the brightness and flicker frequency of these beads, they can display text, images, and videos. Their length can be customized, reaching up to several dozen meters, or even over a hundred meters. LED screens play an important role in outdoor advertising, stage backgrounds, public transportation information displays, and more. Additionally, with advancements in technology, the resolution and picture quality of LED screens continue to improve, leading to their widespread use in televisions, computers, and other areas. In summary, LED screens have become an indispensable part of modern life.

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).
