With the continuous development of China's economy and the improvement of people's living standard, the car has become a necessary means of transportation for every family to travel, but with the increasing number of cars, a large number of car exhaust emissions, leading to increasing environmental pollution in China. In order to solve the problem of environmental pollution, a new energy vehicle came into being. Electric vehicles are a good solution to the problem of exhaust emissions, and electric vehicles are powered by electricity, so charging piles are installed in many public places to solve their charging problems.
The charging pile uses a touch screen to realize the human-computer interaction function. The touch screen provides information such as sweeping code, power level, and equipment status, etc. By using the touch screen to operate the charging, the user will automatically detect the battery status of the system battery through the equipment when charging, in order to accurately predict the appropriate battery charging time current remaining time, power level, and real-time cost, etc.
The functions of the touch screen applied on the charging pile are as follows:
1、Interface display: displaying user IC card information, charging-related information and other contents;
2、Identification: read the information in the IC card, enter the password, identify the user's identity and license plate number;
3、Charging operation: after swiping IC card, confirm automatic charging and interrupt charging;
4、Parameter setting: set charging voltage, charging current, charging duration, fast charging; formula selection models such as small cars, hybrid buses;
5、Charging status: charging status display curve, history data table such as start time, license plate number, set voltage, current, charging duration;
6、Downloading historical data: equipped with U disk to download data function;
7、Network monitoring: monitor the current status of battery and charger, and send the data to the charging station system monitoring center.
