Abstract
An electronic control unit performs a control routine including a step of setting SOC_u(1) as an upper limit value of an SOC and a step of setting SOC_l(1) as a lower limit value when a battery temperature TBs is higher than a first threshold value TBs(1) and a step of setting SOC_u(2) as the upper limit value and a step of setting SOC_l(2) as the lower limit value when the battery temperature TBs is lower than a second threshold value TBs(2).
Claims3
A vehicle comprising:
- a solar battery configured to convert light energy into electric power;
- a power storage device disposed in a vehicle interior of the vehicle, the power storage device being configured to be charged using the electric power output from the solar battery;
- and
- an electronic control unit configured to:
- (i) control charging and discharging of the power storage device such that a state of charge of the power storage device is in a range between an upper limit value and a lower limit value,
- (ii) set a first upper limit value as the upper limit value when a temperature of the power storage device is equal to or lower than a first threshold value,
- (iii) set a second upper limit value as the upper limit value when the temperature of the power storage device is higher than the first threshold value, the second upper limit value being less than the first upper limit value,
- (iv) set a first lower limit value as the lower limit value when the temperature of the power storage device is equal to or lower than the first threshold value,
- (v) set a second lower limit value as the lower limit value when the temperature of the power storage device is higher than the first threshold value, the second lower limit value being less than the first lower limit value,
- (vi) set a second threshold value which is less than the first threshold value,
- (vii) set a third upper limit value as the upper limit value and set a third lower limit value as the lower limit value when the temperature of the power storage device is lower than the second threshold value, the third upper limit value being greater than the first upper limit value, the third lower limit value being greater than the first lower limit value, and
- (viii) set the first upper limit value as the upper limit value and set the first lower limit value as the lower limit value when the temperature of the power storage device is equal to or higher than the second threshold value.
