Description
Technical field
The utility model belongs to the technical field of lithium battery, more specifically to the lithium ion battery package system.
Background technology
The current frequent generation along with climate warming and exceedingly odious weather, energy-saving and emission-reduction are active demands of current social development, various countries are under the policy of energy-saving and emission-reduction, all research relevant policies guide, each large auto producer and relevant automobile research and development unit are in order to cater to public demand and the environmental regulation restriction that meets government, various " green " new forms of energy concept car is come out one after another, to meet world trends.Wherein, electric automobile can be realized what zero discharge, zero was polluted, undoubtedly the main flow of future automobile development in the representative.
Electrokinetic cell is the hybrid vehicle kernel component, the superior direct quality that affects vehicle performance of its performance.Lithium battery has that volume is little, specific energy is high, the life-span is long and the advantage such as environment friendly and pollution-free, becomes the first-selection of electrokinetic cell.But lithium battery is comparatively responsive to temperature, it shows different charging and discharging curve characteristics at different temperature, in same power brick, the difference of temperature is the main cause that causes battery consistency poor, thereby cause battery, battery pack bulk life time and performance significantly descend afterwards in groups.The large-sized power battery used for car load, because the battery cell layout is more, and be subject to the limitation of arrangement space to affect flow field uniformity, and just there are the potential problems of non-uniform temperature in itself.If only depend on the Homogeneouslly-radiating that battery formula levelling and battery pack structure design can not fine solution power brick, must the outfit cooling system.
The utility model content
In order to solve the above-mentioned technical problem existed in prior art, the purpose of this utility model is to provide a kind of lithium ion battery package system, this encapsulating structure has good radiator structure, performance of ventilating is good, in use temperature is even can to guarantee battery pack, cooling efficiency, have good reliability and fail safe.
In order to realize the purpose of this utility model, the utility model has adopted following technical scheme:
A kind of lithium ion battery package system, it includes Battery case, has battery pack in Battery case, in Battery case, near bottom half, is attached with battery management mechanism; Described Battery case is inherent has air inlet mechanism near casing crown center position, in the bottom of Battery case, has air outlet; Described battery pack becomes two row to be symmetrically arranged along the air inlet/outlet direction of Battery case, and the battery pack in each row is arranged in parallel; And form the central ventilated passage between the two row battery pack of left and right, be formed with peripheral vent passages between the inwall of the outside of left and right two row battery pack and Battery case; Wherein said air inlet mechanism comprises intake stack and wind deflector, the area of described wind deflector is greater than the cross-sectional area of central ventilated passage and is less than the cross-sectional area of Battery case, and the distribution density of the regional air outlet of the corresponding central ventilated passage of described wind deflector central authorities is higher than the distribution density of other regional air outlet of wind deflector.
Wherein, the least significant end that relies on air-out direction in described battery pack is provided with deep bead, and the two ends of deep bead extend to the peripheral vent passages in the Battery case outside always.
The utility model compared with prior art has following beneficial effect: vent passages is designed in the layout gap that the utility model takes full advantage of between battery pack, overcome the large problem of serial radiating mode and radiator structure in parallel space that existing battery packaging structure exists, solved the gas long flow path, the shortcoming that cooling effectiveness is low; Especially the air inlet mechanism of unique design has not only guaranteed the temperature homogeneity of battery pack internal cell monomer, and simple in structure, and cost is lower.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model lithium ion battery package system
.
Embodiment
The lithium ion battery package system of this embodiment can be used for electric automobile provides power, as described in Figure 1, it includes Battery case 10 described encapsulating structure, has battery pack 20 in Battery case 10, and Battery case 10 is interior is attached with battery management mechanism 30 near bottom half 12; Described Battery case 10 is inherent has air inlet mechanism 40 near 11 middle parts, casing top, in the bottom 11 of Battery case, has air outlet 50; Described battery pack 20 becomes two row to be symmetrically arranged along the air inlet/outlet direction of Battery case 10, and the battery pack 20 in each row is arranged in parallel; And form central ventilated passage 60 between the two row battery pack of left and right, be formed with peripheral vent passages 70 between the inwall of the outside of left and right two row battery pack and Battery case; The least significant end that relies on air-out direction in described battery pack 20 is provided with deep bead 80, and the two ends of deep bead 80 extend to the peripheral vent passages 60 in the Battery case outside always; Wherein said air inlet mechanism comprises intake stack and wind deflector, and the area of described wind deflector is greater than the cross-sectional area of central ventilated passage and is less than the cross-sectional area of Battery case, and the distribution density of the regional air outlet of the corresponding central ventilated passage of described wind deflector central authorities is higher than the distribution density of other regional air outlet of wind deflector.The utility model is by above-mentioned air inlet mechanism, cooling air is incorporated into to central ventilated passage and peripheral vent passages according to different flows, and at two battery pack mounting block aerofoils of least significant end, stop the air intake air directly to be extracted out from air outlet, make air to battery pack both sides Uniform Flow as far as possible, finally flow through battery management mechanism by outside blower fan extraction Battery case, the battery assembly is played to good cooling effect, thereby in use temperature is even can to guarantee battery pack, cooling efficiency, have good reliability and fail safe.
Vent passages is designed in the layout gap that the utility model takes full advantage of between battery pack, has overcome the large problem of serial radiating mode and radiator structure in parallel space that existing battery packaging structure exists, and has solved the gas long flow path, the shortcoming that cooling effectiveness is low; Especially the air inlet mechanism of unique design has not only guaranteed the temperature homogeneity of battery pack internal cell monomer, and simple in structure, and cost is lower.
Although the embodiment part elaborates the technical solution of the utility model by embodiment, but those of ordinary skill in the art is to be understood that and can breaking away from the utility model scope of disclosure, can adopt to be equal to and replace or the enforcement of equivalent transformation form.Therefore, protection range of the present utility model is not limited to the specific embodiment of embodiment part, as long as no the execution mode that breaks away from utility model essence, within all being interpreted as dropping on the protection range of the utility model requirement.
