Industry Overview


With the deployment and implementation of new energy strategy , Electric vehicles are bound to enter thousands of households . The charging pile application will also be installed in public buildings on a large scale 、 The mall 、 Public parking lot, residential parking lot or charging station . From the form of charging pile , There is a large integrated cabinet machine , There are also small wall hanging machines installed on the wall , Either way , The application of charging pile serial port screen has gradually become standard , Because the charging amount can be displayed through the serial port screen 、 cost 、 Charging time and other data , Amicable HMI The man-machine interface can realize the simple use of the charging pile .


At present, the serial port screen of charging pile mostly adopts 7 " 、10.1 Inch majority , At present, the market competition in the industry is fierce , Competition mechanism makes cost control the focus . To this end, Qiming cloud specially launched based on Lexin ESP32-C3 Low cost and small size serial port screen with high cost performance : Such as 1.54 " 、2.0 " 、2.4 " 、2.8 " , It provides a practical method for the application of charging pile, especially small movable charging pile HMI Human computer interaction solutions .
