Problems solved by technology
As a result, the positioning of the sealing member may become inaccurate or the sealing member may be distorted.
In addition, the operation of removing the film-like burrs generated in the through-hole of the sealing member is also a cumbersome operation, which reduces the productivity when manufacturing the battery cooling system.

Embodiment Construction
[0047] Hereinafter, based on the drawings, the battery cooling system of the first embodiment will be described by taking as an example a battery cooling system for cooling a battery pack for a hybrid vehicle. figure 1 It is a perspective view showing the structure of the battery cooling system of this embodiment in an exploded view. It should be noted that the invention is not limited to the individual embodiments shown below, and can be implemented by changing these modes.
[0048] The battery cooling system uses cooling air to cool the rechargeable battery module 1 by air. The battery cooling system has at least one ventilation path member 3, and cooling air passes through the ventilation path member 3 to be supplied to or discharged from the rechargeable battery module 1. On the upstream side and the downstream side of the ventilation path member 3, other ventilation path members, blower fans, etc. are attached as needed. There may be one or multiple rechargeable battery mod...

Abstract
The invention provides a battery cooling system, which can be manufactured under the state of not reducing assembling efficiency even if a through hole disposed at a sealing element generates film-shaped trimming, and can assemble a sealing element to an expected position. In a battery cooling system, a charging battery module is cooled by air. An opening of the charging battery module is providedwith a ventilating road element in a manner of covering the opening, the cooling air passes through the ventilating road element and is fed or discharged. The sealing element at the periphery of theopening is clamped between the ventilating road element and the charging battery module, and is used for sealing the opening periphery part. The sealing element is provided with a protruding piece forpositioning in an extending manner, and the protruding piece is provided with a through hole. On the other hand, the ventilating road element or the charging battery module is provided with a positioning pin penetrating the through hole. The front end part of the positioning pin is divided in a manner of split pin having air gas of regulated terminal.
Description
Technical field [0001] The present invention relates to a battery cooling system for cooling a battery pack obtained by combining a plurality of rechargeable batteries. In particular, it relates to an air-cooled battery cooling system that uses cooling air to cool a rechargeable battery module including a battery pack. Background technique [0002] In electric vehicles or hybrid vehicles, a battery pack that integrates rechargeable batteries is used as a power source. In the process of charging and discharging, if the battery is overheated or the temperature difference between the batteries becomes large, the performance of the battery is reduced or the battery is damaged. Therefore, the following processing is usually carried out: these battery packs are stored in a battery case, etc. As a rechargeable battery module, cooling air is sent into the battery case to cool the battery pack. [0003] As for the batteries used in the battery pack, there are substantially flat batteries ...
