Description

具有導流隔板結構的電池模組 Battery module with a baffle structure

本發明係與一種電池模組有關,特別是指一種具有導流隔板結構的電池模組。 The invention relates to a battery module, in particular to a battery module having a baffle structure.

按,目前一般動力電池係指為提供機械或機器動力的電池設備,通常動力電池必須擁有高電壓、大電流以有效推動機械進行動作,而作為推動機械之唯一能量,且動力電池亦可應用於電動汽車、電動機車以及電動腳踏車等需較大驅動電力的裝置,因此具有非常關鍵的重要性。 According to the current general battery, it refers to a battery device that provides mechanical or machine power. Generally, a power battery must have a high voltage and a large current to effectively drive the machine to operate, and the only energy to drive the machine, and the power battery can also be applied. Electric vehicles, electric locomotives, and electric bicycles, etc., which require a large amount of electric power, are of critical importance.

惟,一般動力電池主要包含有一殼體,該殼體內利用一固定架或複數隔板將複數個鋰電池予以固定及區隔,從而形成有複數電池組,藉以組合成具有高電壓、大電流的電池組。又,隨著產品所需的電池數量以及操作時間的增加,因此,當以高於額定電流的電流向電池過量充電或發生短路時,容易使該等鋰電池內之電解質溶液溫度上升,並產生氣體,該殼體內中充滿了氣體且無法排出且內部壓力過大時,亦會發生爆炸。而為了防止因氣體之快速膨脹使殼體爆炸,目前殼體之頂板上大多會設置一防爆閥,藉以提供氣體快速膨脹時,衝破防爆閥之阻隔,以達到洩壓的目的。 However, a general power battery mainly includes a casing in which a plurality of lithium batteries are fixed and separated by a fixed frame or a plurality of partition plates, thereby forming a plurality of battery packs, thereby combining to form a high voltage and a large current. Battery. Moreover, as the number of batteries required for the product and the operation time increase, when the battery is overcharged or short-circuited with a current higher than the rated current, the temperature of the electrolyte solution in the lithium battery is easily increased and generated. When the gas in the casing is filled with gas and cannot be discharged, and the internal pressure is too large, an explosion may occur. In order to prevent the shell from exploding due to the rapid expansion of the gas, an explosion-proof valve is usually disposed on the top plate of the casing, so as to provide a barrier for breaking the explosion-proof valve when the gas is rapidly expanded, so as to achieve the purpose of pressure relief.

又,上述習用動力電池內之殼體、固定架或隔板僅具有固定該等電池組之作用,因此,無法有效將該等鋰電池產生氣體引導至該殼體 內部空間之上方位置,換言之,當氣體之快速膨脹時,由於殼體、固定架或隔板沒有設置任何的緩衝或引導氣流之結構,從而發生防爆閥來不及洩放內部的氣體壓力,且氣體壓力亦會直接衝破殼體之頂蓋或內部的內周璧,並使頂蓋或內周璧碎裂及噴發,進而造成電池設備之損壞或使用者之人身危險。 Moreover, the housing, the holder or the partition in the conventional power battery only has the function of fixing the battery packs, and therefore, the lithium battery generating gas cannot be effectively guided to the housing. The position above the internal space, in other words, when the gas expands rapidly, since the casing, the fixing frame or the partition plate is not provided with any structure for buffering or guiding the air flow, the explosion-proof valve is too late to vent the internal gas pressure, and the gas pressure It will also directly break through the inner cover of the top cover or the inside of the casing, and cause the top cover or the inner circumference to be broken and erupted, thereby causing damage to the battery equipment or personal danger to the user.
