연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

A thermal conditioning system for the energy storage system of a hybrid vehicle. At least one auxiliary air source, other than a permanently open air source, has a selectively operable actuator door which either connects or disconnects the auxiliary air source to the energy storage system blower, the air flow being selected to optimally temperature condition the energy storage system. The auxiliary air source preferably includes the HVAC ducting.

1. A thermal conditioning system of a motor vehicle, comprising: a passenger cabin;an energy storage system;at least one permanently open entry vent in fluidic communication with said passenger cabin and with said energy storage system;at least one permanently open exit vent in fluidic communication with said passenger cabin and with said energy storage system;an electronic control system;at least one auxiliary air source other than said passenger cabin, each said auxiliary air source comprising: a duct in fluidic communication with a predetermined air source other than said at least one permanently open entry vent, said duct also being in selective fluidic communication with said energy storage system; andan actuator door selectively movable between a closed position and an open position with respect to said duct, wherein at said closed position said energy storage system is substantially free of fluidic communication with said predetermined air source with respect to said duct, and wherein said actuator door is selectively movable in response to said electronic control system; anda blower connected to said electronic control system and in fluidic communication with said energy storage system, with said at least one entry vent, with the respective said duct of each said auxiliary air source, and with said at least one exit vent;wherein said electronic control system comprises at each said auxiliary air source: an upstream temperature sensor disposed upstream of said actuator door and electrically connected to said electronic control system;a downstream temperature sensor disposed downstream of said actuator door and electrically connected to said electronic control system; andan actuator mechanically connected to said actuator door and electrically connected to said electronic control system, wherein said electronic control system actuates said actuator responsive to said upstream and downstream temperature sensors; andwherein said at least one auxiliary air source comprises a plurality of said auxiliary air sources; wherein said electronic control system moves each respective actuator door to a respectively selected position in order to provide a predetermined optimal thermal management of said energy storage system. 2. The thermal conditioning system of claim 1, further comprising a heating, ventilation and air conditioning module having ducting through which air from said heating, ventilation and air conditioning module fluidically communicates with said passenger cabin; wherein an auxiliary air source of said at least one auxiliary air source comprises the respective duct thereof intersecting said ducting, wherein the predetermined air source thereof comprises the air from said heating, ventilation and air conditioning module. 3. A method for thermal conditioning of an energy storage system of a motor vehicle, said thermal management system comprising the steps of: determining an optimal energy storage system performance temperature range;detecting a thermal condition of the energy storage system by an electronic control system;drawing air from a permanently open air source through the energy storage system in response to said steps of detecting and determining;sensing air temperature of at least one auxiliary air source other than the permanently open air source upstream of at least one predetermined air source switching location;sensing air temperature downstream of the at least one predetermined air source switching location; andselectively drawing air by an actuator mechanically connected to an actuator door from the at least one auxiliary air source at the at least one predetermined air source switching location and through the energy storage system in further response to said steps of detecting, determining and sensing;wherein said step of selectively drawing air comprises selectively varying the amount of the drawn air from at least one auxiliary air source in response to said steps of sensing;wherein said step of selectively drawing air, comprises selectively varying the amount of drawn air from a plurality of auxiliary air sources; andwherein said electronic control system moves each respective actuator door to a respectively selected position in order to provide a predetermined optimal thermal management of said energy storage system. 4. The method of claim 3, wherein said step of selectively drawing air, comprises selectively varying the amount of drawn air from a plurality of auxiliary air sources. 5. The method of claim 3, wherein said step of selectively drawing air comprises selectively varying the amount of drawn air from at least one of a passenger cabin area of the motor vehicle, a trunk of the motor vehicle, an exterior vent of the motor vehicle, and a heating, ventilation and air conditioning module of the motor vehicle. 6. The method of claim 3, wherein said step of selectively drawing air is performed so as to optimally retain the energy storage system within its determined optimal energy storage performance range. 7. The method of claim 3, wherein said step of selectively drawing air comprises selectively varying the amount of drawn air from a heating, ventilation and air conditioning module of the motor vehicle. 8. The method of claim 7, wherein said step of selectively drawing air is performed so as to optimally retain the energy storage system within its determined optimal energy storage performance range. 9. The method of claim 3, wherein said step of selectively drawing air further comprises selectively varying the amount of drawn air from at least one of a passenger cabin area of the motor vehicle, a trunk of the motor vehicle, and an exterior vent of the motor vehicle. 10. The method of claim 5, wherein said step of selectively drawing air comprises selectively varying the amount of drawn air from each of the at least one passenger cabin area of the motor vehicle, and the heating, ventilation and air conditioning module of the motor vehicle. 11. The method of claim 5, wherein said step of selectively drawing air comprises selectively varying the amount of drawn air from each of the at least one passenger cabin area of the motor vehicle, the trunk of the motor vehicle, and the heating, ventilation and air conditioning module of the motor vehicle. 12. The method of claim 5, wherein said step of selectively drawing air comprises selectively varying the amount of drawn air from each of the at least one passenger cabin area of the motor vehicle, the trunk of the motor vehicle, the exterior vent of the motor vehicle, and the heating, ventilation and air conditioning module of the motor vehicle.
