Embodiment Construction

[0047] An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The same reference numerals will be used for the same parts. The names and functions of parts with the same reference numerals are also the same. Accordingly, components with the same reference numerals will be described in detail only once.

[0048] A battery pack cooling system for controlling the temperature of the battery pack, ie, the secondary battery for traveling, will be described below. However, the present invention is not limited to such cooling systems. The object of cooling may be another power source (storage means) for traveling such as a capacitor. In addition to the system for cooling the battery pack, the present invention can also be applied to a system for heating the battery pack, or a temperature control system for cooling / heating the battery pack as required. The system for cooling the battery pack will be mainly explained bel...

Abstract

A temperature requested by a battery pack is achieved efficiently and promptly. A battery pack cooling system includes a battery fan (3200) for cooling a battery pack (3000) in a down flow method; a changing damper (3100) which changes air to be supplied to the battery pack (3000) by using the battery fan (3200) among air in a vehicle compartment, air in a luggage compartment and air whose heat has been exchanged with a rear air conditioning unit; a temperature sensor (3700) which measures a battery temperature; and a battery ECU (6000) which controls the changing damper (3100) and the electric fan (3200) based on the battery temperature, a temperature in the vehicle compartment, and a temperature in a luggage compartment and which outputs an operation request signal for the rear air conditioning unit to an air conditioning ECU (6100).

Description

technical field [0001] The present invention relates to a temperature control system for a vehicle, which controls the temperature of a power source for running, such as a battery installed in the vehicle, such as an electric vehicle, a hybrid vehicle, or a fuel cell vehicle. More particularly, the present invention relates to a temperature control system for a vehicle that can effectively control the temperature of a power source for traveling. Background technique [0002] Each of electric vehicles, hybrid vehicles, and fuel cell vehicles uses an electric motor to obtain driving force for the vehicle, and has a secondary battery as a power source for running. In the case of an electric vehicle, the vehicle is driven by driving an electric motor using electric power stored in a secondary battery. In the case of a hybrid vehicle, the vehicle is driven by driving an electric motor using electric power stored in a secondary battery, or by assisting an engine with the electric...
