一级直流充电桩检定数据

随着电动汽车的广泛使用，公众场合付费的充电桩也越来多，根据《电动汽车非车载充电机（试行）检定规程》JJG1149-2022对送检的一级直流充电桩开展检定，确定被检直流充电桩是否符合规程要求，为政府监管、消费者使用提供参考和技术支撑。1.数据采集:名称、型号、送检单位 厂家、编号、外观及功能检查、温度、电压、电流、按照检定规程要求测得的充电开始时电能被检示值、充电停止充电电能被检示值、标准表测量的电能示值、充电桩显示时间、标准时钟显示时间等信息，2.数据处理:(1)电能示值差=充电停止充电电能被检示值-充电开始时电能被检示值；(2)单次误差=（电能示值差-标准表测量的电能示值）/标准表测量的电能示值；(3)工作误差=(单次误差1+单次误差2)/2；(4)时钟时刻误差=电桩显示时间-标准时钟显示时间,具体运用了TEXT函数；(5)是否符合要求，规程要求外观及功能检查合格、工作误差为±1%、时钟时刻误差≦3s,外观及功能检查、工作误差、时钟时刻误差都符合规程要求的为符合，反之为不符合，具体用了IF、AND、VALUE函数。With the widespread adoption of electric vehicles (EVs), paid public charging piles have become increasingly common. In accordance with the Verification Regulation for Non-on-board Chargers of Electric Vehicles (Trial Implementation) JJG1149-2022, verification is carried out on submitted class 1 DC charging piles to confirm whether they meet the regulatory requirements, providing reference and technical support for government supervision and consumer usage. 1. Data Collection: Collected information includes name, model, unit submitting for verification, manufacturer, serial number, appearance and function inspection results, temperature, voltage, current, the measured energy indicated value at the start of charging, the measured energy indicated value at the end of charging, the energy indicated value measured by the reference standard meter, the display time of the charging pile, the display time of the standard clock, and other information as required by the verification regulation. 2. Data Processing: (1) Energy indicated value difference = Measured energy indicated value at the end of charging - Measured energy indicated value at the start of charging; (2) Single-shot error = (Energy indicated value difference - Energy indicated value measured by the reference standard meter) / Energy indicated value measured by the reference standard meter; (3) Working error = (Single-shot error 1 + Single-shot error 2) / 2; (4) Clock time error = Display time of the charging pile - Display time of the standard clock, with the TEXT function specifically applied for this calculation; (5) Compliance judgment: The regulation stipulates that the appearance and function inspection shall be qualified, the working error shall be within ±1%, and the clock time error shall be ≤3s. Items that meet all the above requirements are deemed compliant, otherwise non-compliant. The IF, AND, and VALUE functions are specifically used for this judgment.
