Example Embodiment

[0027] in figure 1 A module of a plurality of primary battery cells 2 (hereinafter simply referred to as battery cells) is shown in FIG.

[0028] The battery cell 2 is a circular battery cell wound cylindrically. The winding assembly includes a positive electrode (not shown) and a negative electrode (not shown), and a separator and a non-aqueous electrolyte are arranged between the positive electrode and the negative electrode. The current battery cell 2 is a lithium ion battery cell.

[0029] The battery unit 2 is fixed in the bracket 3. The bracket 3 is made of plastic.

[0030] The bracket 3 has a single bottom plate 4 and a double bottom plate 5. The single bottom plate 4 and the double bottom plate 5 are connected to each other by connecting bars 6 such that they are spaced apart from each other and parallel to each other. A channel 7 is formed between every two connecting bars 6. These channels 7 form the cooling air chamber of the battery of the invention. The cooling ai...

Abstract

The invention relates to an electrochemical accumulator comprising a) a plurality of galvanic cells (2), b) a cover, c) a housing sealed by the cover, d) at least one connection pole for electrically contacting the accumulator (1) which is electrically connected to a group of the galvanic cells (2), e) an electrolyte in the housing, f) a cooling air space for receiving cooling air for cooling the cells (2), and g) a degassing space for receiving gas escaping from the cells (2) during a failure. According to the invention, the performance and safety are improved when h) the cooling air space and the degassing space are separated from each other in a gas-permeable manner, and i) the cooling air space and the degassing space are independently lead out of the housing.

Description

technical field [0001] The invention relates to an electrochemical accumulator having the features of the preamble of claim 1 . The invention also relates to a vehicle with an electrochemical battery. Background technique [0002] Powerful accumulators with a high energy density in the primary cells are used in particular in hybrid vehicles (eg vehicles with accumulator and fuel cell units) and in electric vehicles. [0003] High energy density results in high heat release. In order to maintain and ensure the performance capacity of the battery within a wide operating window (given, for example, by the ambient temperature), the battery must be cooled efficiently. [0004] Efficient and cost-effective cooling of the battery is achieved by air cooling. For air cooling, cooling air ducts are provided in the battery between the individual battery cells, through which cooling air is guided by means of fans. [0005] It is known that the cooling air used for the cooling of the...
