SELF-DISCHARGE AMOUNT DETECTION DEVICE OF BATTERY

摘要

PPROBLEM TO BE SOLVED: To provide a self-discharge amount detection device of a battery for detecting the self-discharge amount of the battery during parking by minimizing power consumption of the battery. PSOLUTION: The voltage of a battery pack 2 in the no-load state is estimated from the voltage of the battery pack 2 in the loaded state just before the ignition-off time, and the voltage of the battery pack 2 in the no-load state just after the ignition-on time is subtracted from the estimated voltage of the battery pack 2, and the self-discharge amount of the battery pack 2 during the parking time from the ignition-off time until the ignition-on time is calculated.
