In particular, the battery cooling system may include: a battery cooling apparatus to selectively connected to a cooling apparatus and cool a battery by coolant flowing through the battery cooling apparatus; a battery management system to measure a temperature of the battery in a periodic time interval after a vehicle is turned off; and a controller to control the battery cooling apparatus to cool the battery when the temperature of the batter is higher than a threshold temperature.

The present disclosure relates to a thermal management system for a vehicle including a refrigerant system, a coolant system and a control unit. The coolant system includes a first control loop thermally coupled to an energy storage system, a second control loop thermally coupled to a drive train system, a third control loop thermally coupled to a radiator system, a first multiple valve unit and a second multiple valve unit, and a first heat exchanger configured to transfer heat to the refrigerant system. The first control loop, the second control loop and the third control loop are configured to transfer heat to the first heat exchanger. The first heat exchanger is arranged between the first multiple valve unit and the second multiple valve unit. The control unit is configured to switch the first multiple valve unit and the second multiple valve unit in a first mode to couple the first control loop with the second control loop to collectively transfer heat to the first heat exchanger independently of the third control loop.

A cooling system includes air intakes, air intake fans, a duct, and an intake-air controller. The air intakes are separately formed near seats disposed side by side inside a vehicle. The air intake fans individually take in air through the air intakes. The duct guides the air taken in by the air intake fans to a battery. The intake-air controller controls a ratio of intake air flow rates in the air intake fans according to the state of a seated occupant.

A charging device for charging an energy accumulator unit, in particular a battery pack, of a hand-held power tool. The charging device includes a cooling device for cooling the energy accumulator unit, in particular the battery pack, a charger housing, which at least in sections forms an outer housing, and a receptacle unit which may detachably accommodate the energy accumulator unit, and is provided to accommodate the energy accumulator unit in a connected state and/or hold it at the charging device. The cooling device is provided to form an airflow directed onto the energy accumulator unit in such a way that the airflow at least in sections flows around the energy accumulator unit.

A heat management system and an electric vehicle. The heat management system may be configured in the electric vehicle. A plurality of heat management requirements are generated under different conditions such as different operating conditions (such as driving and a charging request) of the electric vehicle, a current ambient temperature of the electric vehicle, a temperature of a battery pack, or a heat status (that is, a heat value) of a power assembly. Therefore, the heat management system can select different circulation manners of a coolant for different heat management requirements. The heat management system adjusts opening or closing of each valve port in the multi-path direction control valve assembly to select different circulation manners of the coolant, to reduce energy consumption and costs generated when the heat management system performs heat management on the power assembly and the battery pack.
