Method and device for determining the state of function of an energy storage battery
First Claim
1. A method for determining the state of function of an energy storage battery, the method comprising:
- determining a characteristic value for the state of charge of the energy storage battery;
determining a characteristic value for the state of heath when an electrical load is placed on the energy storage battery, the state of health being the suitability of the energy storage battery to emit a specific amount of energy to the at least one load while maintaining a minimum voltage; and
determining a characteristic value for the state of function by linking the characteristic values for the state of charge and for the state of health.

Abstract
In a method for determining the state of function SOF of an energy storage battery, in particular a starter battery for a motor vehicle, as the capability to supply at least one load with an amount of energy, by determining a characteristic value for the state of charge SOC of the energy storage battery and a characteristic value for the state of health SOH when an electrical load is applied to the energy storage battery, with state of health (SOH) being the suitability of the energy storage battery to emit a specific amount of energy to the at least one load while maintaining a minimum voltage, a characteristic value for the state of function (SOF) is determined by linking the characteristic values for the state of charge (SOC) and for the state of health (SOH).
