What should I check if an EV battery report shows more than 100% SoH?
A percentage above 100 can look like proof of an unusually good battery. Before accepting that interpretation, what definitions and calculations should be checked?
EVVerity explains
A closer look
Check the denominator first
An estimate above its chosen reference produces a percentage above 100 by arithmetic. Ask whether the reference is a nominal figure, a measured original value or a provider-specific baseline. That distinction matters more than calling the battery better than new.
Ask for the measurement explanation
Check units, usable versus gross capacity, software version and the provider’s stated uncertainty. Do not cap the number silently or turn it into a purchase recommendation. Keep the reported result as reported and explain why its interpretation needs confirmation.
