Problems solved by technology

The disadvantage here is that the bulky air guide channel duct is a problem in the installation of the battery due to the limited space available in motor vehicles
In addition, these batteries are often located near the ground for the operation of the motor vehicle, so that soil and moisture may be easily sucked into the battery
Finally, the gas escaping from the battery cells is blown to the outside, which involves severe environmental pollution or poses a safety risk in closed spaces
[0012] Finally, the battery described in US 2008 / 0003491 A1 has the disadvantage that the battery cells are cooled very irregularly since the cooling medium only cools the battery cells at few places inside the battery
This leads to an uneven temperature distribution inside the battery, which is why local overheating of the battery cannot be ruled out sufficiently reliably

Embodiment Construction

[0062] figure 1 Shown is a battery 1a comprising a housing 2 and a plurality of galvanic cells 3 (for example lithium-ion cells) arranged in the housing 2, the primary cells having lugs 4 and arranged in the housing 2. 2 to create a fan 5a for fluid flow within the housing 2. According to the invention, the heat exchanger 6a is arranged in the flow path A of the fluid flow. The heat exchanger 6 a comprises forward flow means 7 and counter flow means 8 for the heat transfer medium leading out of the housing 2 .

[0063] In the following examples, air is provided as the fluid. Of course it is also conceivable that the fluid could be a gas, for example, SF 6 , N 2 or CO 2 . The aforementioned gases have fireproof properties, thereby prohibiting or at least suppressing fires in the battery cells 3 . In addition, the above-mentioned gas prevents corrosion in the interior of the battery 1a.

[0064] figure 1 The function of the arrangement shown in is described as follows: ...

Abstract

A battery (Ia.. Ie) having a housing (2) and a plurality of galvanic cells (3) arranged in the housing (2) is provided. In addition, a fan (5a..5c) is arranged in the housing (2) to create a fluid flow circulating inside the housing (2). According to the invention, a heat exchanger (6a..6e) having a forward flow (7) and a return flow (8) for a heat transfer medium, which lead out of the housing (2) is arranged in the flow path (A) of the fluid flow.
