Filed: 2001-03-21
Abstract: PROBLEM TO BE SOLVED: To provide a voltage correction method and a voltage correction device, capable of determining output voltage during a stable period of a high rate battery, immediately after keeping a main relay in a conducting status. SOLUTION: After a charging relay 6 is kept in a conducting status, a main relay 5 is kept in a conducting status, when the charging voltage of a capacitor C1 for stabilizing voltage has reached a prescribed level Von. A period Ton is measured, from the time when the charging relay 6 is kept in a conducting status until the time when the main relay 5 is kept in the conducting status. A charging voltage Vr of the capacitor C1 measured, immediately after the main relay 5, is kept in the conducing status (e.g., after the elapse of 100 ms) and voltage Vs is estimated, when the high rate battery 2 is stabilized, based on the voltage Vr and the period Ton. It is thus possible to determine voltage Vs in the stable period of the high rate battery 2 immediately, after the main relay 5 has been kept in the conducting status.
