EV BATTERY HEALTH TEST: HOW MUCH BATTERY CAPACITY HAS IT LOST?

EV Channels Review

This video provides a practical demonstration of an EV high-voltage battery state-of-health test using the Autel MaxiSys Ultra EV scan tool. The reviewer, Greg, highlights the importance of this test for both prospective used EV buyers and current owners. He walks through the process on a Fiat 500e with approximately 8,000 km, noting its history of frequent DC fast charging and low-state-of-charge usage. Despite these potentially harsh conditions, the test results were surprisingly positive, indicating a 99% state of health. Greg expresses skepticism towards common claims of rapid EV battery degradation, suggesting that many skeptics are misinformed. He concludes that the Fiat 500e's battery is in excellent condition and unlikely to require replacement soon. The video also touches upon the industry practice of using a 70% state-of-health threshold for battery replacement versus the tool's suggestion of 80%, and the concept of unlocking hidden battery capacity. Greg offers his services for this test to viewers in the Montreal area and suggests that battery health certificates should become standard for used EV sales.
