Energy management function activation method for e.g. electric vehicle, involves activating function when state variable involves specific set state, and changing variable from default state to set state by defined external reset signal

摘要

The method involves detecting and/or determining a parameter for determining a current state of a battery (40), and representing validity of values of the detected and/or determined parameter by a state variable (24). The variable is adjusted after a reset operation and/or battery change to a default state. An energy management function (12.1) is activated only when the state variable comprises a set state representing OK. The state variable is changed from a default state to a set state by a defined external reset signal (72). An independent claim is also included for an arrangement for activation of an energy management function in a vehicle.
