A battery temperature adjustment system includes: a battery configured to store electric power from an external power source, and supply electric power to a motor as a drive source of a vehicle; a cooling device to which the electric power from the external power source and the electric power from the battery are selectively supplied and configured to cool the battery; and a control device configured to control the cooling device to lower a temperature of the battery to a target cooling temperature while the vehicle is stopped. The target cooling temperature is a variable value. The control device obtains a target set by a user, and sets the target cooling temperature based on the target.

Disclosed is a method for operating a heat exchanger and an energy store heat exchange system with an energy store including multiple electrochemical cells for providing electrical energy, with a flow duct for providing the cells with a flow of a heat-exchange medium in a flow direction, wherein the cells are arranged in series in the flow direction, wherein the cells each have a heat-exchange surface around which the heat-exchange medium can be made to flow and through which heat can be exchanged between the heat-exchanging medium and the cell, wherein a first (in the flow direction (S)) cell has a first heat-exchange surface, wherein a second cell, arranged downstream of the first cell, has a second heat-exchange surface, the second heat-exchange surface being larger than the first heat-exchange surface, and with an open- and/or closed-loop control unit for setting the volumetric flow.

A vehicle battery pack for an electric vehicle includes a battery, a battery-cooling-air channel, a fume exhaust channel, a fume-ventilation restricting unit, a temperature sensor, a blower fan, and a controller. Cooling air that cools the battery flows through the battery-cooling-air channel. Fumes generated from the battery flow through the fume exhaust channel. The fume exhaust channel is coupled to the battery-cooling-air channel. The fume-ventilation restricting unit closes off the fume exhaust channel from the battery-cooling-air channel in a normal state, whereas causing the battery-cooling-air channel and the fume exhaust channel to communicate with each other in an abnormal state. The temperature sensor detects a temperature of the fumes. The controller controls the blower fan, and increase the air volume of the blower fan on the basis of the temperature detected by the temperature sensor.

Aspects of the disclosure provide a battery pack and a method for charging the battery pack externally. The battery pack can include a charging port configured to charge the battery pack, a cooling circuit configured to cool the battery pack in a vehicle, and a cooling interface configured to connect the cooling circuit with an external cooling device that is external to the vehicle. The charging port and the cooling interface can be integrated into a charging port assembly, the cooling interface has an inlet port and an outlet port that have high pressure quick disconnect leakless fittings, and the battery pack is configured to be charged externally via the charging port. The battery pack can include a plurality of isolating devices configured to determine whether the cooling circuit is connected to the external cooling device.

Disclosed is a power storage unit which can safely operate over a wide temperature range. The power storage unit includes: a power storage device; a heater for heating the power storage device; a temperature sensor for sensing the temperature of the power storage device; and a control circuit configured to inhibit charge of the power storage device when its temperature is lower than a first temperature or higher than a second temperature. The first temperature is exemplified by a temperature which allows the formation of a dendrite over a negative electrode of the power storage device, whereas the second temperature is exemplified by a temperature which causes decomposition of a passivating film formed over a surface of a negative electrode active material.
