At time t1 an ignition-off command is received. In response, a CPU refers to an estimated battery temperature map to obtain an estimated battery temperature corresponding to an outside air temperature obtained at time t1. At time t2, an ignition--on command is received. In response, the CPU obtains an actual battery temperature obtained at time t2 and from the estimated battery temperature and the actual battery temperature calculates a modified, estimated battery temperature for the first received ignition-on command. Furthermore the CPU updates a value corresponding to the outside air temperature obtained at time t1 in the estimated battery temperature map to be the corrected, estimated battery temperature. |
