CONTROL SYSTEM FOR SECONDARY BATTERY, CONTROL CIRCUIT, AND VEHICLE USING THE SAME
A control system for a secondary battery which is less affected by the ambient temperature by performing temperature control of the secondary battery is provided. A control system for a secondary battery which is less affected by the ambient temperature and in which a plurality of kinds of secondary batteries are used for temperature control is achieved and mounted on a vehicle. Specifically, when the ambient temperature is low, some of second secondary batteries are heated by self-heating of a first secondary battery. After the second secondary batteries are sufficiently heated, the rest of the second secondary batteries are heated in stages by self-heating of the some of the second secondary batteries whose temperature has been increased. Whether the some or all of the second secondary batteries are sufficiently heated can be confirmed if the temperatures of a plurality of temperature sensors provided in the second secondary batteries are within the operating temperature range of the second secondary batteries. For example, with the use of a temperature sensing terminal (T terminal) for a temperature sensor, a switch is closed when the internal temperature of the secondary batteries is out of the operating temperature range.
HOT CHARGING SYSTEMS AND METHODS
A hot charging system for an electric vehicle may comprise a battery heating system, a battery cooling system, and a charging system. The hot charging system may be configured to heat a battery module while the battery module is charging and cool the battery module after the battery module is charged. The hot charging system may comprise a plumbing system and a control system. The plumbing system may be configured to place the battery heating system, the battery cooling system, and the battery module in fluid communication. The control system may be configured to charge the battery module via the charging system.

POWER SOURCE FOR INFLATION SYSTEM (THERMAL BATTERY)
A power source for inflation systems. Specific embodiments relate to inflation systems that use an electrically powered inflation system, wherein the power source of the inflation system is a thermal battery. Particular embodiments may find use in connection with inflating evacuation slides or life rafts on board a passenger transportation vehicle, such as an aircraft or marine vessel. Other embodiments may be used for inflating shelters, life vests, or any other inflatable safety device that requires a rapid inflation.
Electrical equipment battery for vehicles
The electrical equipment battery includes: a circuit board mounted with a heat generating element; and an outer case having a heat radiation plate made of metal. A heat transfer space is defined between the circuit board and the heat radiation plate, and then an electrical-insulating and heat-conducting gel is filled in the heat transfer space. Heat energy of the heat generating element is radiated to the outside via the heat radiation plate of the outer case. The heat radiation plate is provided with a flow-out block partition on the outer side of the heat transfer space. The flow-out block partition suppresses the electrical-insulating and heat-conducting gel from flowing out from the heat transfer space.
