Hybrid battery health check (State of Health / SOH)

The hybrid battery is one of the most expensive components in a hybrid vehicle, which is why understanding its real condition is very important. This evaluation is called a hybrid battery health check, also known as SOH - State of Health. During the diagnostic process we analyze battery parameters through the vehicle's computer system. This includes checking the voltage of individual battery modules, the balance between cells, battery performance under load, and how the battery charges and discharges. Over time every battery naturally degrades and some modules may become weaker than others. That is why it is important to evaluate the battery based on real operating data, not only on fault codes. This diagnostic service helps determine the true condition of the battery and can help prevent unexpected hybrid system issues.
