Full title and description

ANSI/UL 2202 — DC Charging Equipment for Electric Vehicles (Third Edition). Standard that sets safety, construction and testing requirements for off‑board DC conductive charging equipment used to recharge propulsion batteries in over‑the‑road electric vehicles; reflects trinational harmonization for North America.

Abstract

UL 2202 (3rd ed., Dec 15, 2022) defines safety and performance requirements for DC fast‑charging equipment (EV chargers and associated power cabinets) intended for input supplies up to 1000 V AC or 1500 V DC and outputs not exceeding 1500 V DC. The standard addresses electrical, mechanical and environmental construction, protective features, marking and instructions, and type and production testing required for listing/certification.

Scope

Applies to DC conductive charging equipment intended to be supplied with a maximum input of 1000 V AC or 1500 V DC for recharging propulsion batteries of electric vehicles, in equipment intended for dry, wet or damp locations as specified. The standard excludes on‑board chargers and some other charger categories identified in its annexes, and it does not cover DC charging equipment intended for use in certain hazardous locations (for example immediate proximity to fuel dispensing). The output of equipment covered shall not exceed 1500 V DC.

Key topics and requirements

• Electrical safety: insulation, grounding, overcurrent and short‑circuit protection, isolation monitoring and residual current considerations.
• Voltage limits: equipment input up to 1000 V AC / 1500 V DC; output limited to 1500 V DC.
• Environmental and mechanical: suitability for dry, wet, or damp locations; enclosure strength, stability, and protection from sharp edges.
• Personnel protection interfaces: references to related personnel‑protection standards (e.g., protective devices and systems used in EV supply circuits).
• Testing: type, performance and production tests for electrical, mechanical, thermal and environmental performance required for listing.
• Marking, instructions and installation requirements to ensure safe deployment and use.
• Harmonization: aligned with trinational requirements (Canada/USA/Mexico) where applicable to support cross‑border conformity assessment.

The key topics above reflect the standard’s technical scope and the kinds of requirements manufacturers and test houses must address.

Typical use and users

Manufacturers and designers of DC fast chargers and power cabinets; test laboratories and certification bodies; component suppliers for EVSE; charging network operators and integrators; utilities, electrical contractors and authorities having jurisdiction (AHJs) who review installations and compliance; and procurement/specification teams evaluating EV charging equipment for safety and interoperability.

Related standards

Commonly referenced companion standards include UL 2594 (EV supply equipment, AC), UL 2251 (plugs/receptacles/couplers), UL 2231‑1 and UL 2231‑2 (personnel protection systems for EV supply circuits), and regional trinational documents such as CSA C22.2 No. 346 and NMX‑J‑817 (harmonized DC charging equipment requirements).

FAQ

Q: What is this standard?

A: UL 2202 is the ANSI/UL standard that specifies safety, construction and test requirements for off‑board DC conductive charging equipment used to recharge electric vehicle propulsion batteries (third edition published Dec 15, 2022).

Q: What does it cover?

A: It covers DC fast‑charging equipment (chargers and associated power cabinets) up to the specified input/output voltage limits, addressing electrical protection, mechanical design, environmental suitability, marking, instructions and testing. It excludes on‑board chargers and certain hazardous‑location uses described in its scope and annexes.

Q: Who typically uses it?

A: Product manufacturers, test labs and certification bodies, charging network operators, installers, utilities, and AHJs use UL 2202 to design, evaluate and certify DC charging equipment for safe deployment.

Q: Is it current or superseded?

A: The third edition (December 15, 2022) is the published edition that supersedes the prior 2009 edition. Note: standards publishers and bodies occasionally publish update notices — for example a standards update notice from 2023 indicated a planned 12/15/2024 edition cycle; always check the UL Standards catalog or the standards publisher for the absolute latest edition, amendments or corrigenda.

Q: Is it part of a series?

A: It is part of the family of EV/EVSE standards (UL 2594, UL 2231‑1/2, UL 2251, etc.) and is harmonized in North America with CSA C22.2 No. 346 and related NMX documents for cross‑border conformity.

Q: What are the key keywords?

A: DC charging, EV charger, EVSE, fast charging, safety standard, UL 2202, DC conductive charging, certification, CSA C22.2 No. 346.
