Description

There is the battery module of high temperature gas passage structure

Technical field

This utility model is relevant with a kind of battery module, particularly relates to a kind of battery mould with high temperature gas passage structure Block.

Background technology

Press, general electrokinetic cell refers to the battery apparatus for providing machinery or machine power at present, usual electrokinetic cell is necessary Have high voltage, high current promotes machinery to carry out action with effective, and the sole energy as promotion machinery, and electrokinetic cell is also Can be applicable to electric automobile, electric motor car and electric bicycle etc. needs the device of larger driving electric, therefore has non-the normally off The importance of key.

Only, general electrokinetic cell consists predominantly of a housing, will be multiple using a fixed mount or multiple dividing plate in this housing Lithium battery is fixed and is separated, thus being formed with multiple set of cells, also or directly inserts in this housing by multiple batteries, mat To be combined into the electrokinetic cell with high voltage, high current.Also, the increasing with the number of batteries needed for product and operating time Plus, therefore, when, easily making in described lithium battery to battery over charge or when being short-circuited with higher than the electric current of rated current Electrolyte solution temperature rises, and produces gas, in this housing in be filled with gas and cannot discharge and when internal pressure is excessive, Also can explode.And in order to prevent from making case fragmentation because of the rapid expanding of gas, the top board of current housing can be arranged mostly One explosion-proof valve, when using offer gas rapid expanding, breaks through the obstruct of explosion-proof valve, to reach the purpose of pressure release.

Also, the fixed mount in above-mentioned existing electrokinetic cell or dividing plate only have effect that is fixing and separating described set of cells, And fixed mount and dividing plate are attached at the outer circumferential side of described set of cells；Therefore, it is impossible to effectively described lithium battery be produced gas guiding To the top position in this enclosure interior space, in other words, when the rapid expanding of gas, because fixed mount or dividing plate are not provided with Any buffering or the structure of guiding air-flow, thus occurring explosion-proof valve to have little time the gas pressure of inside of releasing, and gas pressure Also can directly break through the top cover of housing or the inner circumferential wall of inside, and make top cover or inner circumferential wall fragmentation and eruption, in turn result in connection The electrical equipment damage of battery apparatus or the Personal Risk of user.

Therefore, the application creator after observing above-mentioned disappearance it is believed that the fixed mount in existing electrokinetic cell or dividing plate Structure still has the necessity improveing further, and then has generation of the present utility model.
