System for regulating a charging temperature (T) of a vehicle battery (2) of a vehicle, wherein the vehicle battery (2) is cooled by means of a fluid (F) which circulates in a cooling circuit (21) of the vehicle, which is controlled by a controller (18) such that, upon reaching a charging station, the temperature of the vehicle battery (2) is pre-controlled to a desired charging start temperature (T.sub.0) which is suitable for an electrical charging procedure for speedily charging the vehicle battery (2) by means of the charging station.

During running of an electric vehicle, a battery temperature control section performs preliminary temperature adjustment processing so that a temperature of the battery at a point of time of arrival at a reachable charging station is within a suitable charging temperature range. When the preliminary temperature adjustment processing is performed, a running control section performs processing for maintaining a remaining capacity securing condition that an estimated remaining capacity is equal to or exceeds a remaining capacity criterion value, the estimated remaining capacity resulting from subtraction of an estimated running electricity amount and an estimated temperature control electricity amount from a remaining capacity of the battery at a current point of time.

A vehicle includes a traction battery and a controller. The controller, responsive to a command to enter a highway, confirmation the traction battery can output power to accelerate the vehicle to enter the highway via an entrance at a same speed as traffic on the highway in a vicinity of the entrance, and an increase in temperature beyond a threshold of the traction battery predicted to occur on the highway due to expected commands to maintain the same speed on the highway with power from the traction battery, increases cooling of the traction battery prior to entering the highway.

A charging control apparatus includes: a prediction unit configured to predict a change in temperature of a battery over time during charging; a calculation unit configured to calculate, based on the change in temperature over time predicted by the prediction unit, a degree of influence that the battery receives from the temperature of the battery exceeding a predetermined upper-limit temperature control value; and a charging control unit configured to allow the temperature of the battery to exceed the upper-limit temperature and charge the battery when the degree of influence is less than a predetermined reference value.

A method for operating a traction battery in a motor vehicle, wherein the traction battery is charged in a charging operating state with a fast-charging device. A quantity of energy to be recharged at the fast-charging device is specified. An anticipated heating of the traction battery is determined depending on a charging capacity, which, taking into consideration a predeterminable maximum charging time, is determined from the quantity of energy that is to be recharged. A starting temperature (T.sub.start) for the battery charging is determined in such a way that, after the charging operation has been carried out at the fast-charging device, a battery operating temperature (T.sub.batt) of the traction battery does not exceed an upper limit (T.sub.hi) for the battery operating temperature. The battery operating temperature (T.sub.batt) is recorded during a driving operating state of the motor vehicle.

A desired departure temperature is determined for a battery, having a temperature, in a vehicle based at least in part on trip information associated with a trip. A temperature controlling system is used to bring the temperature of the battery towards the desired departure temperature, wherein the vehicle begins the trip with the battery at the desired departure temperature.
