IEC TS 61851-3-4:20 23 IEC 61851的这一部分是一项技术规范，适用于在供电网络和电动道路车辆或可拆卸可充电储能系统（RESS）之间进行电力传导传输的CANopen通信或电动道路车辆的车载可充电储能系统（RESS）。 用于控制电池系统和电压转换器单元(VCU)之间的功率传输的能量管理系统(EMS)为可以参与能量管理控制的所有设备提供通信。 能源管理系统（EMS）的基本应用概况由IEC TS 61851-3-4、IEC TS 61851-3-5、IEC TS 61851-3-6、IEC TS 61851-3-7组成。

IEC TS 61851-3-4:2023 This part of IEC 61851, which is a Technical Specification, applies to CANopen communication for the conductive transfer of electric power between the supply network and an electric road vehicle or a removable rechargeable energy storage system (RESS) or on-board rechargeable energy storage systems (RESS) of an electric road vehicle.
The energy management system (EMS) for control of power transfer between battery systems and voltage converter units (VCU) provides the communication for all devices that can take part in energy management control.
The basic application profile for energy management systems (EMS) consists of IEC TS 61851-3-4, IEC TS 61851-3-5, IEC TS 61851-3-6, IEC TS 61851-3-7.
