摘要： A battery state determining apparatus is provided which can accurately determine a state of a lead battery in an automotive vehicle. The apparatus calculates a corrected engine starting voltage Vst1 from an open-circuit voltage (OCV) measuring section that measures the open circuit voltage Vst of the lead battery at an engine starting time in accordance with a temperature of the vehicle. The apparatus further calculates a battery determination voltage Vst_th representing a voltage of the lead battery at an engine starting time when a growth rate of internal resistance of the lead battery reaches a predetermined value from the open-circuit voltage OCV. The apparatus then determines the battery state of the lead battery by determining whether the corrected engine starting voltage Vst1 is larger than the battery determination voltage Vst_th and whether the corrected engine starting voltage Vst1 belongs to a predetermined region on a characteristic map.
