Battery State of Charge Reference Chart
INFORMATION
This chart indicates the approximate open circuit voltage when the SoC (State of Charge) of the battery is known: either from an energy diagnosis test plan or as displayed in the Kombi when in transport mode.
The values below are for AGM (Absorbed Glass Mat) batteries and may vary slightly, depending on temperature.
The Open Circuit Voltage (OCV) is the voltage of the battery without a current load.
The vehicle must be in sleep mode for at least 6 hours without being disturbed in order for the OCV to be accurate.
