Battery State Of Health (SoH)
State of health shows remaining battery capacity compared with new.
What is Battery State Of Health (SoH)?
It is given as a percentage. It decreases with age. Tests measure it. Some cars show the value in a menu or app; otherwise a workshop or specialist tester can read it. Independent battery certificates are becoming common when selling used electric cars. Battery warranties often guarantee around 70 percent of capacity after a set number of years or kilometres.
How it works
The BMS estimates capacity.
Why it matters for your car
Readings vary by method. Warranty often covers a minimum.
