Abstract
The invention relates to a sealed battery pack, in particular to a sealed battery pack for electric vehicles. According to the technical scheme of the sealed battery pack, the battery pack is formed by connecting a plurality of cavities made of an aluminum alloy material, the two ends of each cavity are open, and the rest part of each cavity is sealed, the shape and size of each cavity are matched with the shape and size of each cylindrical battery, and holes allowing outgoing lines of the batteries to be led out therein are formed in the outer side wall of the battery pack, the batteries are placed in the cavities, and the two ends of each cavity are sealed with a sealing material. The sealed battery pack has the advantages that the operation is simple, the technical difficulty is low, the sealing performance is reliable, and the breakdown-resisting performance is good.
Description
Technical field
The present invention relates to a kind of power brick, particularly relate to a kind of electric vehicle sealed cell bag.
Background technology
Electrokinetic cell bag is a large core of electric automobile, and the waterproof seal of power brick directly has influence on the use safety of electric automobile.It is according to electric motor car load request, by multiple cell or ultracapacitor connection in series-parallel comprising modules, then is made up of the battery pack of certain voltage and capacity multiple module connection in series-parallel, and the box house being placed on a sealing forms power brick.In power brick, battery pack can produce heat in charge and discharge process, if these heats can not distribute in time, gently then can affect the use of battery pack, shortens the life-span of battery pack, heavy what for security incident occurring; When electric automobile uses at low ambient temperatures, because of the poor performance at low temperatures of battery, cause electric motor car normally not use or distance travelled short, charge especially at low temperatures, directly affect the life-span of battery.Usual heat radiation and insulation are conflicts, so improve the serviceability temperature environment of battery pack, are that battery pack product quality improves in manufacturer, guarantee the safe and reliable important step that must solve of electric motor car.
Traditional power brick is by being coated with fluid sealant in casing commissure, and box cover and lower cover cooperation place add encapsulant.For preventing power brick from puncturing, battery two-stage and electric level connecting plate need ensure safe distance, and above factor causes conventional batteries bag needs just can complete under the human users of specialty.
Summary of the invention
Based on this, be necessary to provide a kind of simple to operate, technical difficulty is low, and sealing is reliable, the power brick that anti-breakdown performance is good.
The technical solution used in the present invention is:
A kind of sealed cell bag, described power brick is by multiple both ends open, the cavity that the aluminum alloy materials of all the other position seals is made is formed by connecting, the shape and size of described cavity and the shape and size of columniform battery suitable, the lateral wall of described power brick has the hole that the lead-out wire for battery is drawn.
Described battery is positioned in cavity, and the two ends encapsulant of cavity seals.
Due to the application of technique scheme, the present invention compared with prior art tool has the following advantages:
1, sealed cell bag of the present invention solves the problem that conventional batteries bag needs just can complete under professional's operation, and simple to operate, technical difficulty is low.
2, power brick of the present invention, aluminium alloy outer wall construction can effectively prevent power brick breakdown, and profile and the size of the profile of the cavity of power brick and size and columniform battery are suitable, can better self-contained battery.
The two ends of originally open cavity when battery is placed on after in cavity, are adopted encapsulant to seal, make whole power brick have good water resistance, are conducive to improving the useful life of power brick and the fail safe of use by 3, power brick of the present invention.

figure.
Above
in accompanying drawing: 1, cavity, 2, battery, 3, hole, 4, encapsulant, 5, lead-out wire.
Embodiment
Below in conjunction with
accompanying drawingand embodiment is to this
inventionbe further described:
Embodiment one:
as Fig. 1-2shown in, a kind of sealed cell bag of the present invention, described power brick is by multiple both ends open, the cavity 1 that the aluminum alloy materials of all the other position seals is made is formed by connecting, the shape and size of described cavity 1 and the shape and size of columniform battery 2 suitable, the lateral wall of described power brick has the hole 3 that the lead-out wire 5 for battery is drawn, sealed cell bag of the present invention, select to adopt aluminum alloy materials as the material of main part making cavity 1, because the outer wall construction of aluminum alloy materials can effectively prevent power brick breakdown, the profile of the cavity 1 of power brick and the profile of size and columniform battery 2 and size suitable, can better self-contained battery.
Preferably, as an embodiment, described battery 2 is positioned in cavity 1, the two ends encapsulant 4 of cavity 1 seals, when battery 2 is placed on after in cavity 1, adopt encapsulant to seal at the two ends of originally open cavity 1, make whole power brick have good water resistance, be conducive to improving the useful life of power brick and the fail safe of use.
The above is this
inventionpreferred implementation, it should be pointed out that for those skilled in the art, do not departing from this
inventionunder the prerequisite of described principle, can also make some improvement or replacement, these improve or replace and also should be considered as this
inventionprotection range.
