Technical Problem
当车辆在恶劣工况下完成补能和用能后，转而在良好工况下再次补能时，前后补能阶段所记录的电能差异可能与实际消耗存在出入，可能导致用户认知和电站计费系统显示数据之间出现不一致的情况，也导致补能计费结果出现误差
Benefits of technology
通过将采集单元布置在车辆的电池电芯组与高压箱之间，当电池电芯组发生充放电动作时，也就是车辆用电时，采集单元，例如霍尔传感器能够即时响应并生成相应的感应电流，为后续的数据处理提供准确数据。计量单元接收采集单元输出的感应电流，可通过例如直流计量芯片将瞬时感应电流转化为计量信号，从而实现了对充放电总量，也就是车辆实际用电量的准确计量。在与计费装置连接后，通讯单元可将计量单元输出的计量信号发送至例如计费平台的计费装置。在低温环境下电池储能能力下降时，计量单元仅记录实际的计量信号，而非基于标称容量的理论值，从而消除因工况差异导致的误差。计费方可以根据获取到的计量信号进行计费，保证计费平台可以获取准确的车辆用能，减少车辆补能计费误差。
