Description
Technical field
The utility model relates to the power battery technology field of new-energy automobile, is specifically related to a kind of impact-resistant power battery pack device.
Background technology
Along with continuous intensification and the air pollution of energy crisis, advocate green energy resource in global range, national governments support the development of new-energy automobile energetically, and electrokinetic cell develops rapidly.Thump effect under the weak percussion produced when normal traveling due to vehicle and the exceedingly odious condition such as to collide, all can have a strong impact on security performance and the life-span of electrokinetic cell.The shock resistance of battery is to ensureing that the fail safe of battery, durability and reliability are most important.Therefore towards the extensive industrialization of battery, the research and development of the shock resistance of electrokinetic cell must be paid much attention to.
Because the technology of electrokinetic cell is limited to, electrokinetic cell is extremely harsh to the requirement of working temperature.Battery module can produce a large amount of heat histories in the process of discharge and recharge, cause battery module the too high and temperature that is battery cell of temperature seriously uneven.Too high temperature and uneven Temperature Distribution can cause the thermal runaway of battery, the dangerous accident such as even to blast.Adopt the heat management system of air cooling or liquid cooling, although the temperature of battery can be reduced, the homogeneous temperature distribution of battery cell can not be ensured.In order to efficient cooling power battery, the heat management device of power battery with phase-change material that is efficient, low cost must be studied.
Utility model content
In order to solve above-mentioned prior art Problems existing, the utility model provides a kind of impact-resistant power battery pack device, percussion effectively can not only be avoided the impact of the performance of battery, and realize the effective cooling of inside battery and reach the uniformity of single battery Temperature Distribution.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of impact-resistant power battery pack device, comprise cabinet shell 1, be placed in the inner shell of a box body 2 in cabinet shell 1, cavity is formed between described shell 1 and inner shell of a box body 2, nano-fluid 3 is filled in this cavity, described inner shell of a box body 2 inside separates into multiple battery case 5 by dividing plate 4, is filled with phase-change material and is placed with electrokinetic cell in each battery case 5, and the top of described cabinet shell 1 and inner shell of a box body 2 is provided with upper cover 6.
Described each battery case 5 is dispelled the heat by mode that is air-cooled or water-cooled.
Described phase-change material is chosen according to the Suitable ranges of electrokinetic cell work.
Compared to the prior art comparatively, the utility model possesses following advantage:
In the utility model structure nano-fluid can apparatus with shock absorbing and absorb battery produce heat, phase-change material also can absorb battery produce heat.Realize the impact resistance of battery and efficient heat management in a device simultaneously.This device is simple and have wide range of applications, and percussion effectively can be avoided the impact of battery and improve the efficiency of heat management and the performance of battery.
Accompanying drawing explanation
Accompanying drawing is the impact-resistant power battery assembling structural representation of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in drawings, a kind of impact-resistant power battery pack device of the utility model, comprise cabinet shell 1, be placed in the inner shell of a box body 2 in cabinet shell 1, form cavity between described shell 1 and inner shell of a box body 2, fill nano-fluid 3 in this cavity, described inner shell of a box body 2 inside separates into multiple battery case 5 by dividing plate 4, in each battery case 5, be filled with phase-change material and be placed with electrokinetic cell, the top of described cabinet shell 1 and inner shell of a box body 2 is provided with upper cover 6.
When casing is subject to any percussion, nano-fluid absorbs this impact energy, thus avoids electrokinetic cell to be subject to the impact of percussion.Fill phase-change material in the battery case separated by dividing plate, in battery operated process, phase-change material utilizes the principle absorbing a large amount of latent heat in its phase transition process to absorb the heat history of battery generation.According to demand, in battery case, the object of heat radiation also can be reached by air-cooled and method that is water-cooled.Owing to adopting phase-change material can take into account each battery, so both can ensure to reduce battery temperature, also can ensure the temperature uniformity of battery cell, thus improve battery thermal management efficiency.In this example, phase-change material is chosen according to battery operated Suitable ranges.
