EV Battery SoH Certificates
Independent Assessment and Verification Brings Trust and Transparency to EV Battery Health
Certified Test Results Build Trust
The CARA Battery Health workgroup is established to create common standards to facilitate remarketing and support residual values of used cars through trust in the battery of a BEV, easily to be communicated to buyers, by an independent assessment and certification.

THE STANDARD
The current standard for certified electric vehicle battery diagnostics was developed by Europe’s Car Remarketing Association, or CARA. Manufacturers of EV battery diagnostic tools that have been successfully tested by CARA carry the Battery Health Check CARA Approved® seal. The seal is included on each EV VERIFIED Certificate.The CARA Battery Health workgroup was established to create these common standards to support residual values of used cars through trust in the battery of a certified BEV and to be easily to be communicated to buyers, by an independent assessment and certification.
The workgroup aims to deliver what follows:
- Facilitate remarketing and support residual values of used BEV cars
- Provide buyers’ confidence in the battery
- Provide a clear and comprehensive presentation of the result
- Establish an independent assessment and certification process Deliverables
- Set the standard for a State of Health (SOH) Measurement (CARA Approved Battery Health Check ®) for the remarketing industry in Europe
- Evaluate technology and process possibilities for vehicle individual battery assessment
- Review, validate and real-life test technologies for obtaining SOH data
- Propose a settlement process in case of disputes of buyers (warranty management; not in Scope of Step one)
EV BATTERY HEALTH TEST FAQs
Answers to frequently asked questions about EV battery tests.
Q1. What Makes and Models does EV VERIFIED test?
A complete list of EV VERIFIED, Inc. EVs tested is listed on the MODELS page and includes over 50 of the most common makes and models of electric vehicles.
Q2. How long is a high-voltage EV battery test?
A Premium Test is an in-depth, dynamic diagnostic test that requires the vehicle to be charged to 100% and then driven down to 10% charge (usually within 7 days) to measure live degradation and cell performance.
The benefit of a Premium Test is better forecasting of future range and degradation based on live degradation and cell performance data collected over several days.
Q3. What does the battery test measure?
Commercial-grade, EV battery State of Health, SoH, tests measure vehicle communications, sensors, temperature, current, battery management system, the battery pack and battery cell voltages.
Q4. What is EV battery State of Health, SoH?
High-voltage EV battery State of Health, SoH, is the percentage of remaining battery storage capacity from the 100% it had when it left the factory. This measurement helps to determine remaining range and current value of a used EV. A bad EV battery replacement could cost as much or more than the vehicle sale price.
Q5. What State of Charge, SoC, should my EV be at for the test?
High-voltage EV batteries receiving a rapid test should be at 40-80% State of Charge, SoC. Premium Tests require the electric vehicle to be fully charged to 100% before the test commences.
