A DC meter (1) for an electrical vehicle charging station having a pair of DC power supply lines (27a, 27b) extending from a charging station controller (40) to an electrical vehicle connector (28), the DC meter comprising a meter unit (2) and a sensor unit (3). The meter unit comprises a user interface (9), a sensor interface (11) for connection to the sensor unit (3), a metering interface (30) for connection to the charging station controller, and a microprocessor (10) configured to receive and process signals received from the sensor unit (3), to exchange data with the charging station controller and to receive commands from the user interface and output information to the user interface. The sensor unit is separate and connected at a point distal from the meter unit via an interconnection cable (25) for the transmission of measurement signals, the sensor unit being coupled to one of the pair of DC power supply lines (27a, 27b) configured for measuring the current flowing through said power line, the sensor unit further comprising a voltage sensor (6) for coupling to each of the pair of power supply lines for measuring a voltage difference therebetween.

    用于电动车辆充电站的DC仪表(1),具有从充电站控制器(40)延伸到电动车辆连接器(28)的一对DC电源线(27a、27b),DC仪表包括仪表单元(2)和传感器单元(3)。仪表单元包括用户接口(9)、用于连接到传感器单元(3)的传感器接口(11)、用于连接到充电站控制器的计量接口(30)和微处理器(10),其被配置为接收和处理从传感器单元(3)接收的信号、与充电站控制器交换数据以及从用户接口接收命令并向用户接口输出信息。传感器单元是分离的,并经由用于传输测量信号的互连线缆(25)在远离仪表单元的点处连接,传感器单元耦合到一对DC电源线(27a、27b)中的一条DC电源线,被配置为测量流过所述电源线的电流,传感器单元还包括用于耦合到一对电源线中的每条电源线的电压传感器(6)以测量该对电源线之间的电压差。
