Overview

IEC TS 61851-3-7:2023 is a Technical Specification from the International Electrotechnical Commission (IEC) that covers CANopen communication for DC conductive charging between the supply network and an electric road vehicle (EV) or a removable Rechargeable Energy Storage System (RESS) / traction battery. It applies specifically to DC EV supply equipment where protection relies on double or reinforced insulation and specifies the battery system application objects used for battery-to-charger data exchange.

Key topics

Scope and purpose: Defines the CANopen-based message and object model for battery system communication during conductive DC charging.

Finite State Automaton (FSA): Operating principles and state definitions for battery system interaction with DC EV supply equipment.

Object dictionary / application objects: Detailed definition of produced and consumed CANopen objects for battery systems (examples in the TS include objects such as 6100 Type of battery cells, 6164 Relative battery system Wh capacity (SOC), 6176 SOH, temperature, cell voltages and capacity counters).

Data types and structures: Complex data types, grouped sub-indices and object value structures to ensure consistent interpretation.

Battery-specific parameters: Temperature limits, maximum/minimum cell voltages, capacity metrics (Wh / Ah), balance and lifecycle counters, and charging/discharging rules where applicable.

Optional and mandatory objects: Differentiation between strictly required objects and optional objects for enhanced monitoring (relevant for swap/rental battery systems).

Applications

Enables interoperable communication between DC charging stations and EV battery systems using CANopen.

Supports battery management and safe charging control, including state of charge (SOC), state of health (SOH), cell voltage monitoring, and temperature-based protections.

Useful in battery swap / rental models where mandatory identification and cell-voltage objects are needed for safe interchangeability.

Applicable to manufacturers of DC EV supply equipment, EV OEMs, battery pack designers and integrators, and software developers implementing CANopen profiles for charging.

Who should use this standard

EV and RESS/traction battery manufacturers implementing CANopen interfaces.

Charging station OEMs designing DC EVSE that rely on double or reinforced insulation.

BMS engineers, system integrators, test laboratories and compliance teams verifying battery–charger interoperability.

Fleet operators and service providers managing swap/rental battery systems.

Related Standards (if applicable)

Part of the IEC 61851 series on electric-vehicle conductive charging systems and aligns with CANopen communication practices. Implementers should consult other IEC 61851 parts and CANopen (CiA) documentation for complete system-level requirements.

Keywords: IEC TS 61851-3-7:2023, CANopen, DC EV supply equipment, conductive charging, battery system communication, SOC, SOH, BMS, RESS, double or reinforced insulation.
