Full title and description

IEEE Std 2030.1.1-2021 — IEEE Standard for Technical Specifications of a DC Quick and Bidirectional Charger for Use with Electric Vehicles. This standard defines technical specifications for direct-current (DC) quick chargers and bidirectional DC chargers (vehicle-to-grid / vehicle-to-home capability) to promote safe, interoperable, and consistent rapid charging of battery electric vehicles and the interface between vehicle and off-board DC charging equipment.

Abstract

Provides design interfaces, electrical and control characteristics, performance and interoperability requirements, and recommended practices for DC quick chargers and bidirectional chargers used with electric vehicles. The standard addresses charger types, power levels, communication and control considerations needed for safe fast charging and for supporting bidirectional power flow where vehicles act as energy storage resources.

Scope

Specifies the technical interface and requirements for off-board DC quick chargers and bidirectional DC chargers used to charge and, where supported, discharge energy from battery electric vehicles. Topics include electrical characteristics and ratings, interconnection and protection, functional behavior during charging/discharging, basic communication/control interactions with the vehicle, and guidance for interoperability to enable widespread, safe, and reliable fast charging infrastructure. The scope is focused on DC (off-board) charging systems rather than on-board AC conversion.

Key topics and requirements

• Definitions and classifications of DC quick chargers and bidirectional chargers (power levels, connector types, operational modes).
• Electrical ratings and power delivery characteristics (voltage/current ranges, steady-state and transient behavior).
• Protection and safety requirements (isolation, grounding, fault protection and safety interlocks).
• Communication and control interfaces between vehicle and charger (protocol considerations to coordinate charging, authorization and charge session management).
• Requirements and guidance for bidirectional operation (V2G / V2H use cases, control of power flow, interoperability considerations).
• Interoperability recommendations to align with other EV charging standards and connector specifications.

Typical use and users

Used by EV charger manufacturers, electric vehicle OEMs, charging-network operators, infrastructure planners, electrical engineers, test laboratories, and procurement/specification teams involved in deploying DC fast-charging stations or integrating bidirectional charging capabilities. Also used by utilities and system integrators when defining requirements for grid interconnection and managed charging programs.
