The invention relates to a method for determining a value of the state of energy (SOE) of a rechargeable battery (5) in a vehicle (1; 1), said battery (5) being connected to an electric consumer (4); said method comprising: determining the state of charge (SOC) as a measure of the present capacity of said battery (5); and determining said state of energy (SOE) as an indication of at least the remaining charge and discharge energy of said battery (5). The method according to the invention further comprises: calculating and determining said value of the state of energy (SOE) based on at least one parameter (I, R, SOCmax, SOCmin) which is related to the operation of said electric consumer (4) and where said at least one parameter (I, R, SOCmax, SOCmin) varies depending on a mode for operating said vehicle (1; 1) or electric consumer (4) during charging or discharging of said battery (5). The invention also relates to an arrangement for determining a value of the state of energy (SOE) of a rechargeable battery (5) in a vehicle (1; 1). |
