交流充电桩检定数据

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《电动汽车交流充电桩检定规程（试行）》JJG 1148-2022对送检的交流充电桩开展检定，确定被检交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，规程要求一级交流充电桩外观及功能检查合格、工作误差为±1%、时钟时刻误差≦3s；二级交流充电桩外观及功能检查合格、工作误差为±2%、时钟时刻误差≦3s，当外观及功能检查、工作误差、时钟时刻误差都符合规程对应等级要求的为符合，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 grown increasingly common. Per the *Verification Regulation for AC Charging Piles of Electric Vehicles (Trial)* JJG 1148-2022, inspections are carried out on submitted AC charging piles to verify whether they meet the regulatory requirements, providing reference and technical support for government supervision and consumer usage. 1. Data Collection: Collected data includes the name, model, submitting unit for inspection, manufacturer, serial number, results of appearance and function inspection, temperature, voltage, current, the measured display values of electric energy at the start and end of charging as specified by the verification regulation, the electric energy display value measured by the standard meter, the time displayed by the charging pile, and the time displayed by the standard clock, among other information. 2. Data Processing: (1) Electric energy display difference = Electric energy display value at charging end - Electric energy display value at charging start; (2) Single-charge error = (Electric energy display difference - Standard meter measured electric energy value) / Standard meter measured electric energy value; (3) Working error = (Single-charge error 1 + Single-charge error 2) / 2; (4) Clock time deviation = Time displayed by charging pile - Time displayed by standard clock, for which the TEXT function is specifically utilized; (5) Compliance determination: The regulation specifies that for Class 1 AC charging piles, the appearance and function inspection must be qualified, the working error must fall within ±1%, and the clock time deviation must be ≤3s; for Class 2 AC charging piles, the appearance and function inspection must be qualified, the working error must fall within ±2%, and the clock time deviation must be ≤3s. A charging pile is considered compliant only if it satisfies the corresponding grade requirements for appearance and function inspection, working error, and clock time deviation; otherwise, it is deemed non-compliant. The IF, AND, and VALUE functions are specifically employed for this determination.
