Electric vehicles conductive charging system. DC EV supply equipment where protection relies on double or reinforced insulation. General definitions and requirements for CANopen communication | Status: Current

1 Scope 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.
