Description
Technical field
The utility model is related to electric automobile power battery technical field, more particularly to a kind of soft-package battery module.
Background technology
At present, in power battery industry development, soft-package battery has been obtained for being widely applied.Soft-package battery is generally adopted
Battery core is partially encapsulated in aluminum plastic film with heat pressing process, and connected again after soft-package battery is placed in fixing bracket or
Person is connected in parallel.For example, the Chinese patent application No. is 201520943399.7 discloses a kind of soft-package battery module, the technology
With Insulating frame receiving and securing unit soft-package battery in scheme.This frame mode is complex, processing and installation cost compared with
It is high.
Invention content
To solve the above problems, the utility model proposes a kind of soft-package battery module, the structure of the soft-package battery module
Simply, processing cost is relatively low, and improves the reliability of product.
A kind of soft-package battery module, including housing and multiple battery cores, the battery core includes two opposite polarity lugs,
The housing includes top panel, bottom panel, two side panels, rear panel, stent and aluminium row, and lug and the aluminium of the battery core are arranged
It is fixed together, the soft-package battery module further includes the battery core spacer of multiple sheets, the battery core and battery core
Spacer is located at enclosure interior, and spaced superposition.
Further, viscose glue is carried on two faces of the battery core spacer.
Still further, the battery core spacer of the sheet is rectangular sheet foam.
Further, the multiple battery core is mutually parallel, neatly arranges.
Further, the lug of the battery core is welded and fixed with aluminium row.
The beneficial effects of the utility model are mainly manifested in：1. simple in structure, processing cost is low；2. battery core spacer can delay
It rushes battery core and sends out expansion thermogenetic, and battery core can be bonded, the battery core after superposition is made to become an entirety, single battery core is played
Position-limiting action improves reliability of operation and stability.
Description of the drawings
Fig. 1 is the overall structure figure of the utility model soft-package battery module.
Fig. 2 is the explosive view of soft-package battery module shown in Fig. 1.
Specific embodiment
In order to which the purpose of this utility model and advantage is more clearly understood, with reference to embodiments to the utility model into
Row is further described.It should be appreciated that specific embodiment described herein is not used in limit only to explain the utility model
Determine the utility model.
The present embodiment is illustrated with reference to Fig. 1-2.
Soft-package battery module 1 as shown in Figs. 1-2, including housing 2 and multiple battery cores 3, it is opposite that battery core 3 includes two polarity
Lug 301 and 302.Housing 2 includes top panel 203,201, two side panels 204 of bottom panel, rear panel 202, aluminium and arranges 205 and
Stent 206 is to be fixedly connected between adjacent panel, and lug and the aluminium row 205 of battery core 3 is fixed together, this practicality
In novel, to be welded and fixed between lug and aluminium row 205.
Soft-package battery module 1 further includes the battery core spacer 4 of multiple sheets.Battery core 3 is located at housing 2 with battery core spacer 4
Inside, and spaced superposition.It is mutually parallel between multiple battery cores 3, it is neat to arrange.
In the utility model, battery core 3 adjacent thereto can be bonded with viscose glue on two faces of battery core spacer 4,
The battery core after superposition 3 is made to become an entirety, position-limiting action is played to single battery core.In addition, battery core spacer 4 itself may be used also
It sends out expansion thermogenetic to buffer battery core, improves the safety of battery modules entirety.
In the utility model, the sheet battery core spacer 4 is rectangular sheet foam, in addition to this, battery core spacer
Other materials can also be used, it is desirable that there is insulation performance and certain elasticity, the volume expansion after being heated with buffer battery.
This programme is different from the scheme provided in documents：1. without setting fixing bracket for single soft-package battery, and
Using battery core with battery core spacer is spaced be superimposed by the way of, enormously simplify overall structure, reduce processing cost and production
The reliability of product；2. the setting electricity of battery core spacer can buffer battery core and send out expansion thermogenetic, the reliable of product is improved
Property；3 battery core spacer double-sides belt glue make the battery core spacer after superposition become an entirety, limiting are played to single battery core
Effect improves the stability of operation.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, under the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
