Title:
DEVICE AND METHOD FOR DETERMINING REPLACEMENT OF STORAGE BATTERY
Document Type and Number:
WIPO Patent Application WO/2007/125906
Kind Code:
A1
Abstract:
A control unit (16) in a device for determining the replacement of a storage battery
charges one or more target battery modules (10), measures by a voltage measuring
device (14) the voltage variation value for a certain time after the charging
of the battery modules (10) is stopped. When the voltage variation value exceeds
a reference voltage variation value continuously for a predetermined number
of times equal to or more than one time, it is determined that the battery module
(10) is needed to be replaced.
