The present invention relates to a method (1) for controlling the preconditioning of at least one traction battery (201) of an electric vehicle (200), the method (1) comprising:charging (101) an auxiliary battery (202) from at least one power source (203); estimating (102) the amount of auxiliary battery charge required to precondition the traction battery (201); obtaining (103) charge rate information indicative of at least one charge rate affecting property of said at least one power source (203), wherein said at least one charge rate affecting property includes weather forecasts, driving schedule of the vehicle, time of day, day of week, week of year, historical charge rate data, and/or said at least one power source's (203) output voltage, output current, and/or output power; estimating (104) a charge rate of the auxiliary battery (202) based on said charge rate information; comparing (105) the estimated amount of charge required to precondition the traction battery (201) with the estimated charge rate of the auxiliary battery (202) and allocating (106) an overcapacity thereof to the powering of at least one auxiliary system (204) of the vehicle (200).
