<P>PROBLEM TO BE SOLVED: To provide a battery system allowing a battery to discharge with a suitable discharge pattern, for example, to control progress of deterioration of the battery, as well as a vehicle and a battery-loaded device equipped with such a battery system. <P>SOLUTION: The battery system includes a lithium ion secondary battery having a power generating element and an electrolyte containing lithium salt, a discharge control means for controlling a discharge current DC from the lithium ion secondary battery, and a voltage detection means for detecting a battery voltage. The discharge control means has relation acquisition means S20, S30 for sequentially acquiring a relation between a lapsed time TD since the start of the discharge and the battery voltage in a series of discharge period JD during which the discharge current continues to flow, and controls an amount of the subsequent discharge current based on the already acquired relation between the lapsed time and the battery voltage in the series of the discharge period. <P>COPYRIGHT: (C)2010,JPO&INPIT |
