Abstract
The utility model discloses a single lithium battery casing special for a pure electric automobile, which relates to the technical field of batteries. A retraction plate A (5) and a retraction plate B (6) are symmetrically arranged outside a single soft package battery (7) along two sides of thickness-direction of the single package battery. The retraction plate A and the retraction plate B are wave thin wall plates. Two ends of the wave thin wall plates are straight sections. Protruding arc sections of the retraction plate A and the retraction plate B close to the single soft package battery clamp the soft package battery correspondingly. The two ends of the retraction plate A and the retraction plate B are fixed inside fixed plates through the straight sections. The fixed plate is arranged in groove of the lateral walls. The single battery can be firmly fixed by the casing, and the casing enables single batteries to avoid damage caused by expansion of single batteries bodies under working conditions of battery units and can ensure heat dissipation of the single battery.
Description
Technical field
The utility model relates to the battery technology field, is specifically related to a kind of pure electric automobile specialized lithium battery cell shell.
Background technology
Battery pack system is one of electric automobile three big core technologies, and the advantage of this system is determining useful life (comprising operating cost), the automobile continuation of the journey mileage of battery to a great extent, also is related to the security performance of vehicle simultaneously.
Battery pack system can be divided into power-supply management system and temperature control system substantially on function; And battery cell is as unit the most basic in the battery pack; According to the needs of vehicle operating, just must deposit its shell, thereby reach protective effect to lithium battery Soft Roll individual design.
Up to now, mainly be charge and discharge process management about the research direction of power-supply management system to battery, battery temperature detects, aspects such as cell voltage current detecting, and to the housing further investigation of vehicle-mounted cell.
The global design of Vehicular battery group and common batteries group exists difference:
1, vehicle moves under rugged road conditions, just must consider the stability and the fastness of battery pack system.
2, since the limitation of interior space the battery pack dense degree is higher in addition, must consider that therefore battery cell crosses the danger that thermal expansion causes.
Summary of the invention
The invention technical problem to be solved provides a kind of pure electric automobile specialized lithium battery cell shell; This shell can be firm the stable cell monomer, under the intensive operational environment of battery pack, can avoid battery cell can not expand and not cause danger each other because self using; And can guarantee the heat radiation of battery cell.
For realizing the foregoing invention purpose, following technical scheme is adopted in the invention:
The pure electric automobile specialized lithium battery cell shell of the utility model; It is outside at the soft-package battery monomer; Along soft-package battery monomer thickness direction bilateral symmetry constriction plate A, constriction plate B are set, said constriction plate A, constriction plate B are made as the wavy thin plate, and the two ends of thin-walled part are flat segments; Said constriction plate A, constriction plate B are near the corresponding clamping soft-package battery of the protruding segmental arc monomer of soft-package battery monomer; Said constriction plate A, constriction plate B are arranged in the fixed head through flat segments, and fixed head places in the groove of sidewall.
Be better implement the invention, the groove of said fixed head and sidewall forms interference fits.
Be better implement the invention, on the said sidewall length direction shell holddown groove be set uniformly-spaced.
Because adopt aforesaid technical scheme, the invention has following superiority:
1, cell (ambient temperature, working temperature is moderate) under safe work state, the Soft Roll of battery cell can not expand; At this moment constriction plate A; The inwardly protruded segmental arc of constriction plate B is pressed close to battery Soft Roll middle part, plays support and stabilization to the battery Soft Roll, makes battery cell in the vehicle ' process, can not occur significantly vibrating; Make Soft Roll be in a kind of mild state, reached effective antihunt action.
2, cell (excessively discharge and recharge and the influence of ambient temperature under) under abnormal operating state causes the Soft Roll in the battery cell overheated, causes that Soft Roll expands; Constriction plate A, constriction plate B are under the effect of tension force, and protruding segmental arc is expanded to both sides respectively; But because elastic force effect; Still be in the state of closely cooperating, reached antihunt action equally with the Soft Roll outer wall, and the danger that produces of the cell extruding of having avoided bringing owing to expanding each other.
3, the waveform cambered surface of constriction plate A, B design can make the outer surface of battery fully contact with cold and hot medium, thereby reaches owing to the change of the external temperature influence to battery.
Description of drawings
Fig. 1 is the structural representation of pure electric automobile specialized lithium battery cell shell;
Among the figure: 1-right side wall; 2-right fixed head; 3-left side wall; 4-left fixed head; 5-constriction plate A; 6-constriction plate B; 7-soft-package battery monomer; 8-positive source; 9-power cathode; 10-shell holddown groove.
Embodiment
Below in conjunction with preferred implementation the invention is further specified:
In conjunction with Fig. 1; The pure electric automobile specialized lithium battery cell shell of present embodiment is in the outside of soft-package battery monomer 7, along soft-package battery monomer thickness direction bilateral symmetry constriction plate A5, constriction plate B6 is set; Constriction plate A, constriction plate B are made as the wavy thin plate, and the two ends of thin-walled part are flat segments; Constriction plate A, constriction plate B are near the corresponding clamping soft-package battery of the protruding segmental arc monomer of soft-package battery monomer; Constriction plate A, constriction plate B two ends are separately positioned in left fixed head 4, the right fixed head 2 through flat segments clamping soft-package battery monomer 7 two ends; Fixed head 4, right fixed head 2 place in the groove of sidewall, with the groove formation interference fits of sidewall.The shell holddown groove uniformly-spaced is set on the sidewall length direction.
Wherein, constriction plate A, constriction plate B mainly adopt the aluminum alloy materials of good heat conductivity, and be in light weight, good toughness.
The pure electric automobile specialized lithium battery cell shell of present embodiment can be under the condition of jolting, and firm stable cell monomer can avoid battery cell can not expand and not cause danger because self using each other under the intensive operational environment of battery pack.
