Document Type and Number:
WIPO Patent Application WO/2008/066092
Kind Code:
A1
Abstract:
A secondary battery charge/discharge control device mounted on a vehicle (100)
includes: a temperature sensor (42) for detecting temperature (TB) of a battery
(B); and a control device (30) for setting a battery power to be charged or discharged
by the battery (B) according to the temperature (TB) detected by the temperature
sensor (42) and the charge state of the battery (B). As the temperature of the
battery (TB) increases, the control device (30) increases at least one of the
following values: a first value indicating the charge state when charge and discharge
of the battery (B) is switched from one to the other; a second value indicating
the charge state when the battery power charged to the battery (B) when the charge
state is lowered than the first value has reached a limit value; and a third value
indicating the charge state when the battery power discharged from the battery
(B) when the charge state exceeds the first value has reached the limit value.
