Problems solved by technology

[0003] However, it has been found in practice that since the lithium battery pack generates heat during use, and the batteries 2 are in close contact with each other, if any one of the batteries 2 has thermal runaway (thermal runaway) , the heat energy will quickly spread to other batteries 2, resulting in thermal runaway of other batteries 2, which will cause a chain reaction of thermal runaway, which will easily cause the entire battery pack to heat up rapidly and overheat, resulting in the battery pack being easily damaged

Embodiment Construction

[0024] refer to image 3 , 4 , an embodiment of the battery device of the present invention includes a case 4, several batteries 5, and several ceramic heat insulating papers 6.

[0025] refer to Figure 4~7 The housing 4 of this embodiment includes a first shell 41 and a second shell 42 , a covering shell 43 , a front plate 44 , and a rear plate 45 , which are opposite to each other at intervals from left to right. Although the housing 4 of this embodiment is assembled from the above-mentioned several components, some components can also be integrated to reduce the number of components during implementation.

[0026] The first casing 41 and the second casing 42 jointly define an installation space 40 between them and are combined on opposite sides of the battery 5 . The structure of the first housing 41 and the second housing 42 are substantially the same, both have a side wall 411 extending forward and backward, an end wall 412 connected to the rear end of the side wall 4...

Abstract

Provided is a battery device having ceramic insulating paper and a heat dissipating passage, comprising a casing defining a mounting space, a plurality of batteries, and at least one ceramic insulating paper. Each battery includes a body and two electrodes connected to the body. The body of the battery is disposed in the installation space at vertical intervals. The at least one ceramic thermal insulation paper is disposed between the batteries to insulate thermal energy conduction between the batteries. The ceramic insulating paper is arranged between the batteries in order to insulate thermal energy conduction. When any one battery loses control, other batteries are prevented from being affected at lower speed by arranging the ceramic insulating paper. Therefore, chain effect of thermalrunaway of all batteries is avoided. The batteries are stable in application and long in service lifetime.

Description

technical field [0001] The invention relates to a battery device, in particular to a pouch cell device. Background technique [0002] refer to figure 1 , 2 , a lithium battery pack provided for China Taiwan Patent No. M296482, comprising: a housing 1 including an upper cover 11 and a lower cover 12, several batteries 2 arranged in the housing 1, and a battery pack with The collector plate 3 of several jacks 31. Each battery 2 has two electrodes 21. After the electrodes 21 pass through the socket 31 of the collector plate 3, the electrodes 21 are bent and connected together to electrically connect the batteries 2 to form a battery with the required voltage. lithium battery pack. [0003] However, it has been found in practice that since the lithium battery pack generates heat during use, and the batteries 2 are in close contact with each other, if any one of the batteries 2 has thermal runaway (thermal runaway) , the heat energy will quickly spread to other batteries 2, ...
