EVs & Related Equipment
From the electric vehicle charging station and its cables, adapters, and couplers to your EV’s fuses, wires, and batteries, our standards are hard at work keeping you safe from potential hazards and risks.
What is the Risk to You?
The moment you plug in your electric vehicle and begin charging, an extraordinary amount of electricity instantly passes through the charging cable and into your EV battery — sometimes enough to power an entire house.
UL standards help you avoid harm from hazards posed by EVs. And as the number of EVs in use has grown exponentially, along with the associated risks, safety standards have evolved to help you protect yourself.

Standards in Action
A safety standard is like an instruction manual put together by experts to guide the testing of products, services, and systems to make them safer for you.
Our standards library for EV technology is broad and growing, not only addressing the batteries, fuses, and polymeric electrical equipment in your vehicle, but also charging systems, cables, and couplers, as well as wireless power transfer equipment and more.
Updated Standard Contributes to EV Battery Circularity
Every day, hundreds of EV batteries reach the end of their initial service life — but that doesn’t mean they have to end up in the landfill. Learn UL 1974 helps repurpose these retired power sources (which still hold up to 80% capacity) into vital energy storage systems. From maintenance protocols to remanufacturing requirements, this standard provides the rigorous framework needed to help safely extend the service life of EV batteries. Keep reading to learn more.

most commonly asked
How likely are EV batteries to catch fire?
EV fires are statistically rarer than conventional vehicle fires, but fires caused by lithium-ion batteries, which power EVs, are faster and more aggressive than other fires.
Fires can occur from damage, manufacturing defects, or charging system failures. Damaged or malfunctioning lithium-ion batteries, which power EVs, may slip into thermal runaway — an uncontrollable, self-heating state that can end in fire.
Our catalog of standards for EV technology not only covers the batteries, fuses, and polymeric electrical equipment in your vehicle, it also covers charging systems, cables, and couplers, as well as wireless power transfer equipment and more. Additionally, our standard for evaluation for repurposing or remanufacturing batteries provides requirements for the sorting and grading process involved in repurposing batteries from their original configuration in electric vehicles to use in other applications, such as energy storage.
Yes, damaged batteries pose risks from stranded energy — remaining electrical charge that can cause fires or shocks. Let first responders handle crashed EVs and follow manufacturer protocols.
EV batteries typically last 8–10 years on average. Most manufacturers warranty batteries for this period. Performance gradually declines to about 70–80% capacity, at which point replacement or repurposing is recommended.
By using proper equipment installed by qualified electricians, you can minimize the risk of charging electric vehicles at home. Such home charging systems have multiple safety features, including ground fault protection.
Key features include ground fault protection, thermal monitoring, overcurrent protection, and proper weatherproofing. Equipment should meet safety standards such as UL 2594 or UL 2202.

EV Safety Standards
Safety standards have the power to save lives. Explore UL standards that improve EV technology safety for you.
UL 2580: Batteries for Use in Electric Vehicles
UL 2580 is a standard for EV battery systems that covers the safety aspects of these systems’ design, construction, installation, and operation. It specifies requirements and tests to help protect against electric shock, fire, mechanical, and environmental hazards. It also guides the proper handling, transportation, and recycling of EV battery systems.
UL 2750 Wireless Power Transfer Equipment for Electric Vehicles
UL 2750 covers wireless equipment for transferring power to a stationary electric vehicle. It includes requirements for testing any foreign object detection and living object detection systems to evaluate for reliability in protecting persons from hazards.
UL 2596: Test Method for Thermal and Mechanical Performance of Battery Enclosure Materials
This test method evaluates the thermal and mechanical performance of battery enclosure materials in response to stresses representative of the thermal runaway of lithium-ion cells used in EVs.
Our catalog includes more than 1,700 safety standards and documents that are regularly updated and added to. Click below to keep exploring how our standards are making the world safer for you.
Get Involved
The best standards are made possible by diverse voices and deep collaboration. Be part of the process by helping inform the next generation of standards.
Technical Committees
Each TC is a diverse group of experts representing a broad range of perspectives and interests, including consumers, manufacturers, regulators, supply chain professionals, and more.
As a TC member, you will review proposals for new or revised standards and work collaboratively to achieve consensus through balloting in our transparent process.
Stakeholders
Stakeholders can submit, review, and comment on proposals for new standards or revisions to existing standards. While these individuals cannot vote, the TC considers their input during the standards voting process. Since standards affect everyone, all are welcome to participate as stakeholders.
