<p><P>PROBLEM TO BE SOLVED: To calculate a SOC (state of charge: charging rate) by utilizing a correlation relation of pseudo OCV (Open Circuit Voltage: open terminal voltage) and the SOC by making an internal part state corresponding to open of an on-vehicle battery. <P>SOLUTION: A vehicle is provided with an on-vehicle generator 7 to be driven by an engine, a voltage control device 8 for adjusting power generation amount of the generator 7 and the on-vehicle battery 5 for accumulating power generated in the generator 7. The voltage control device 8 temporarily stops the power generation of the on-vehicle generator during working of the engine. When the power generation amount is gradually increased, battery voltage is detected when charging/discharging current of the battery is in a very small prescribed range. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
