摘要 |
<P>PROBLEM TO BE SOLVED: To a discharge ability estimating system for estimating a discharge ability of a battery without directly measuring or estimating an internal resistance or a maximum discharge current amount of the battery. <P>SOLUTION: This engine ECU 40 estimates the discharge ability of the battery 21 that supplies power to a motor 23 which rotates a crankshaft 19 of the engine E to start the engine E. The engine ECU 40 estimates the discharge ability of the battery 21, based on an angular acceleration state of the crankshaft 19 in a rotation start period of the crankshaft 19. <P>COPYRIGHT: (C)2013,JPO&INPIT |
