CONTROL DEVICE FOR ELECTRIC VEHICLE, AND CONTROL METHOD FOR VEHICULAR BATTERY

摘要

PROBLEM TO BE SOLVED: To suppress discharge reserve variations by preventing a gas generation amount from being varied between power generation elements that are accommodated in a plurality of accommodation parts, in terms of control.SOLUTION: The present invention relates to a control device for an electric vehicle comprising a battery 15 with which power generation elements 15d are accommodated in a plurality of accommodation parts 15b. When internal resistance of the battery 15 is defined as R, a terminal voltage of the battery 15 is defined as V, a current that flows through the battery 15 is defined as I and an electromotive force of the battery 15 that is calculated under V+I×R is defined as E, the electromotive force E of the battery 15 is monitored and charge of the battery 15 is controlled in such a manner that the electromotive force E does not exceed a predetermined upper limit value. The predetermined upper limit value is determined by a temperature of the battery 15 and the current I that flows through the battery 15.SELECTED DRAWING: Figure 1
