Problems solved by technology

[0012] However, the implementation of this active cooling function by forced air circulation consumes part of the energy of the battery and thus reduces its operating time
Furthermore, the presence of at least one actuator and some moving parts results in the need for regular maintenance, greater weight, and these batteries cannot survive in wet environments, even in rain, without the risk of severe corrosion or short circuits at the contacts of the battery elements. use

Embodiment Construction

[0038] Figure 1-7 , 9, 11 and 12 show a portable battery device 1 comprising a generally parallelepiped-shaped housing 2 and a battery pack 3 housed in the housing 2, the housing having a height H, a width L and Thickness E.

[0039] The battery pack 3 consists of a plurality of battery elements 4 having an elongated, preferably cylindrical, sealed body 4"' comprising two opposite ends 4', 4". The battery element 4 is preferably a cylindrical accumulator of type 18650 lithium-ion technology. Other sizes including non-cylindrical sizes and other battery technologies may of course also be used within the scope of the present invention.

[0040] These battery elements 4 are arranged side by side on the one hand with interstitial spaces between adjacent battery elements 4 , and on the other hand are formed in one piece (according to the first embodiment of the invention) or consist of at least two stacked or juxtaposed A battery pack 3 composed of three sub-packs 3"' (which wi...

Abstract

The present invention relates to a portable battery device (1) comprising a casing and a battery unit (3) housed therein, and consisting of a plurality of battery elements (4). The battery device (1)is characterised in that it comprises surface means for compartmentalising (7, 7') the internal volume of the casing, defining sealed housings (8'), in that the ends (4', 4'') of the elements (4) comerespectively into supporting engagement, by or with the opposite end portions of the bodies (4''') of the battery elements (4), with the opposite compartmentalising means (7, 7'), and in that the remaining parts (11) of the bodies (4''') of said elements (4) situated between the opposite compartmentalising means (7, 7') are directly exposed to the outside environment through perforated or discontinuous portions of the wall (6) of the casing.

Description

technical field [0001] The invention relates to the field of autonomous power sources, in particular power battery systems that can be transported or even carried by the user, usually on his back, and also aims at a portable battery unit incorporating a passive air cooling system. Background technique [0002] Various embodiments of portable batteries (under the English term "batterypack") for powering power tools are known in the prior art. [0003] Such batteries generally consist of an assembly of a plurality of battery elements having an elongated, preferably cylindrical, sealed body comprising two opposite ends. [0004] The battery elements are on the one hand arranged side by side with interstitial spaces between adjacent battery elements, on the other hand they are arranged in one piece or in battery packs consisting of at least two subgroups stacked on top of each other or juxtaposed, and finally the battery The elements are electrically coupled to each other at ea...
