摘要：
At time t1 an ignition-off command (IGOFF(1)) is received. In response, a CPU refers to an estimated battery temperature map to obtain an estimated battery temperature (#Tb(1)) corresponding to an outside air temperature (Tout) obtained at time t1. At time t2, an ignition-on command (IGON(1)) is received. In response, the CPU obtains an actual battery temperature (Tb(1)) obtained at time t2 and from the estimated battery temperature (#Tb(1)) and the actual battery temperature (Tb(1)) calculates a modified, estimated battery temperature (#Tb_NEW(1)) for the first received ignition-on command (IGON(1)). Furthermore the CPU updates a value corresponding to the outside air temperature (Tout) obtained at time t1 in the estimated battery temperature map to be the corrected, estimated battery temperature (#Tb_NEW(1)).
