Abstract

There is provided a temperature control device for a battery of a vehicle which has a battery housing having a battery which is arranged therein and which is intended to have its temperature controlled, and a battery heat transmission device, which are arranged with spacing from each other so as to form an intermediate space, wherein a temperature control medium can be introduced into the intermediate space. The temperature control device further has a delimitation device, an air chamber which is arranged between the battery heat transmission device and the delimitation device, an air inlet opening for supplying ambient air to the air chamber and an air outlet opening for discharging air from the air chamber. In order to increase the efficiency of the battery cooling, it is proposed to construct the air inlet opening so as to be able to be closed. There are further provided a vehicle having such a temperature control device and a method for controlling the temperature of a battery which is arranged in a battery housing of a vehicle by means of a temperature control medium.

First claim

What is claimed is:

1. A battery system for a vehicle comprising:
a battery;
a heat transmission device spaced from the battery such that an exterior surface of the heat transmission device adjacent to the battery and the battery define form a gap configured to receive a temperature control medium; and
an underfloor paneling spaced from the heat transmission device such that the underfloor paneling and an exterior surface of the heat transmission device closest to the underfloor paneling define an air chamber between the underfloor paneling and heat transmission device, the air chamber having an air inlet and air outlet that are selectively closable based on temperatures of the temperature control medium and ambient air.

2. The battery system of claim 1 further comprising a controller configured to, responsive to the temperature of ambient air being greater than the temperature of the temperature control medium, close the air inlet and air outlet.

3. The battery system of claim 1 further comprising a second heat transmission device configured to exchange heat between the temperature control medium and air.

4. The battery system of claim 1 further comprising a second heat transmission device configured to exchange heat between the temperature control medium and a refrigerant.

5. The battery system of claim 1 further comprising temperature control medium lines configured to deliver the temperature control medium to the gap.

6. The battery system of claim 1 further comprising a controller configured to, responsive to the temperature of ambient air being less than the temperature of the temperature control medium, open the air inlet and air outlet.
