TH15544C3 - Cooling system for battery packs in electric vehicles - Google Patents

Abstract

1 page of the number 1 page summary of the invention This invention involves The cooling system for the battery pack in electric vehicles consists of - the cabin air conditioning subsystem 220, which consists of a 222 evaporator or evaporator coil, a 320 evaporator or condenser and a compressor. 310 with cooling fluid circulating within the subsystem - Battery pack cooling subsystem 120 To reduce the battery temperature, pack 110 contains an evaporator, 122, which receives the fluid. Make The cooling subsystem for the 120 battery pack is housed in a closed-loop system 130 housing and no gas. inflammable (non-flammable gas) or inert gas circulating within The invention based on this invention uses a cooling system built into the vehicle for cooling purposes. Hot for battery pack So that the battery pack can work at its best And prolong the service life of Battery Pack It also saves energy.

Claims (8)

Disclaimer (all) which will not appear on the advertisement page: page 1 of the number 2 disclaimers 1. Cooling system for battery packs in electric vehicles Includes - passenger compartment air conditioning subsystem (220) consisting of an evaporator or evaporator (222), an outdoor unit or condenser (320) and a compressor (310) with fluid. Refrigeration circulates inside the subsystem - the battery pack cooling subsystem (120) to reduce the temperature of the battery pack (110), consisting of an evaporator or evaporator (122) adopted. Fluid made The cooling that has been cooled down by the condenser (320) is characterized by the cooling subsystem for the battery pack (120) is contained, the housing (130) is a closed system (130). loop system) and contains non-flammable gas. (non-flammable gas) or inert gas circulating within 2. Cooling system for battery pack According to claim 1, where the non-flammable gas is nitrogen gas 3. Cooling system for battery pack According to claim 1, whereby the drain subsystem Thermal The battery pack (120) also includes a fan (124) for the inert or inert gas in the closed loop housing. 4. Cooling system for battery pack According to claim 1, whereby the drain subsystem The thermal battery pack (120) is also included. Pressure release control system, non-flammable or inert gas (140) for maintaining pressure in closed system housing (130). 5.Cooling system for battery packs According to claim 4, with the emission control system Non-flammable or inert gas pressure (140) includes a non-flammable or inert gas cylinder (142), a pressure transmitter (144) for measuring pressure in a closed system housing (130), a control device. Pressure controller (146) serves to receive the signal from the pressure gauge set (144) to control the opening-closing of the pressure-adjusting valve (148) and the pressure-adjusting valve (148) to supply or block the non-flammable gas. Or inert gas from the cylinder (142) to adjust the pressure in the housing (130), which is a shut-down system, page 2 of the number 2 6.Cooling system for battery pack According to claim 1, whereby the drain subsystem Cabin heat (220) is additionally equipped with a fan (224) for circulating the cabin air (210). 7.Cooling system for battery packs According to claim 1, whereby the drain subsystem The cabin heating (220) is additionally equipped with a fan (330) for sucking air from outside through the outdoor unit or condensing unit (320) to reduce the temperature of the cooling fluid. 8.Cooling system for battery packs According to claim 1 or 7, where the hot coil or condenser (320), which serves to reduce the temperature of the cooling fluid It is connected to the expansion valve (340) for reducing the pressure of the cooling fluid before being supplied to each subsystem.
