An aircraft hybrid cooling system is disclosed. The aircraft hybrid cooling system includes a conduit through an aircraft that is configured to allow airflow through the conduit. The aircraft hybrid cooling system additionally includes a battery assembly positioned in the conduit, configured to provide for airflow past a battery in the battery assembly in a first mode of operation and configured to provide flow of a cooling medium past the battery in a second mode of operation. In some embodiments, the battery in the battery assembly is cooled via airflow in the event the aircraft is in flight and is cooled via an applied cooling medium in the event the aircraft is grounded.

A battery pack has improved safety. The battery pack includes a battery module having at least one battery cell; and a thermal runaway suppression unit mounted to one side of the battery module and configured to form a positive pressure inside the battery module when an abnormal situation occurs in any one battery cell.

The battery cooling device that cools a battery by circulating a refrigerant by a compressor and cools air blown into a vehicle compartment, and when the battery is being rapidly charged, the rotation speed of the compressor is increased. More specifically, the upper limit rotation speed of the compressor is increased to a predetermined rotation speed. At this time, the predetermined number of revolutions is determined based on a maximum allowable noise level at the time of rapid charge of the battery.

A method and system for controlling a temperature control system based on both system reliability and battery state is disclosed. Batteries may supply power to places where the power grid is unavailable. The batteries may be housed in containers, with the temperature and humidity of the containers being controlled using a temperature control system. The system and method disclosed may select the temperature setpoint and humidity setpoint in order to operate the batteries within prescribed temperature and humidity values, while considering both the state of health of the batteries (e.g., the battery state of charge) and the state of health of the temperature control system (e.g., the failure of the compressors). In this way, the batteries may be operated within prescribed limits while accounting for both the health of the batteries and the health of the temperature control system.

A hybrid vehicle includes an internal combustion engine, a filter, an electrical storage device, a rotating electric machine, and a controller. The filter is configured to trap particulate matter in exhaust gas of the internal combustion engine. The rotating electric machine is configured to generate electric power using power from the internal combustion engine so as to charge the electrical storage device, and drive the internal combustion engine using electric power from the electrical storage device. The controller is configured to control the internal combustion engine and the rotating electric machine, so as to warm up the electrical storage device when regeneration control needs to be performed and when the temperature of the electrical storage device is lower than a reference value. The regeneration control is control for raising the temperature of the filter to a predetermined temperature so as to burn the particulate matter. The controller may be configured to execute the regeneration control when the temperature of the electrical storage device exceeds the reference value.
