State of Charge and State of Health Analysis for EV Battery Condition
A live webinar hosted by TST and Motor Age Training, sponsored by Autel
Summary
As electric vehicles become more prevalent, accurate evaluation of battery health is essential for ensuring safety, performance, and longevity. This webinar, featuring “G” Jerry Truglia and Pierre Respaut of Technicians Service Training (TST), explores proper diagnostic methods for assessing both State of Charge (SOC) and State of Health (SOH) — two critical indicators of an EV battery’s true health condition.
Attendees will gain insights into:
- The principles behind SOC and SOH analysis and what they reveal about battery performance
- The differences between on-board diagnostics and direct testing methods
- How to safely perform high-voltage system measurements and interpret results
- Common challenges in diagnosing EV and hybrid batteries and how to overcome them
- Real-world best practices for maintaining reliability and safety during testing
This session will help vehicle technicians better understand the science and strategy behind comprehensive EV battery evaluation.
