Document Type and Number:
WIPO Patent Application WO/2008/053808
Kind Code:
A1
Abstract:
A vehicle power supply device includes: a main power source (11), a load (15) connected to
the main power source (11), an accumulation unit (31) for accumulating power of
the main power source (11), and a control circuit (43) which supplies power to
the load (15) from the accumulation unit (31) when the voltage (Vb) of the main power
source (11) is lowered to a predetermined threshold value or below. The control
circuit (43) inhibits power supply from the accumulation unit (31) to the load
(15) when the vehicle is not in use and when power is supplied from the main power
source (11) to a starter (23) to start an engine of the vehicle and no power is supplied
from the main power source (11) to the load (15).
