Generally, the EV charge station are outdoors, so most of the LCD screens selected by the charging piles are also high-brightness LCD screens. The main core of the high-brightness LCD screen is the packaging process of the DLED backlight and its application to light efficiency. Above, if the technology is not up to standard, then the light efficiency will not be improved. The high-brightness screen may emit more heat. At the same time, it also needs its heat dissipation technology to reduce the temperature of the backlight, so as to ensure the DLED backlight. Normal usability, when used outdoors, it is an environment that produces heat. At present, there are companies on the market that add aluminum profiles to the back cover of the screen to dissipate heat, but this does not solve the fundamental problem.
What are the general types of LCD screens on EV Charger?
There are two ways to divide the charging pile LCD screen model. First, according to the size: 10.1inch,12.1inch ,19 inches, 22 inches, 32 inches, 42 inches, 47 inches, 55 inches, 65 inches. Secondly. Divided by brightness: 1000cd, 1500cd, 2000cd.
1. High brightness: most of the charging piles are installed outdoors, and the outside light is sufficient. The general LCD screen can not see the display content under strong light, so choose a high-brightness color LCD screen or a monochrome semi-transparent LCD screen. Ensure that the display content on the LCD screen can be seen clearly under high brightness
2. Normal operation at low temperature: Since most of them are installed and used outdoors, the influence of temperature changes must be considered. Components with a lot of temperature will not start. Therefore, low temperature LCD screens should be used to ensure that they can work normally when the temperature is too low. Frostbite the device
3. Anti-interference: charging piles are mostly installed in various parking lots (residential, commercial buildings, enterprises, roadside parking spaces, etc.), special charging stations (bus, logistics, transportation hubs, high-speed processing stations, etc.). Comparison of electronic equipment in these places It will cause interference to the charging pile, so the LCD screen must have anti-interference function。
EV Charger can be fixed on the ground or on the wall, and are generally installed in public buildings, residential quarters parking lots or charging stations. They can charge various types of electric vehicles according to different voltage levels. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided on the charging pile to perform the corresponding charging method, charging time, and charging time. Cost data printing and other operations, the LCD screen on the charging pile can display some data such as charging amount, cost, charging time and so on.
