Embodiment
Describe the turnover wind system of battery case of the present utility model in detail below in conjunction with accompanying drawing.
Provide a kind of battery case of electric automobile referring to Fig. 1 and Fig. 4 the utility model, this battery case has air inlet 3 and air outlet 4, and wherein air inlet 3 has increased air strainer, and air outlet 4 has the powerful cooling fans 13 of number row.Like this, in the car load driving process, constantly enter air, filter out dust in air, prevent that battery from producing pollution through air strainer from the external world by air inlet.Many rows cooling fan by the air outlet setting carries out forced ventilation, thereby plays cooling effect well.
About other preferred structure and the advantage of the turnover wind system of the utility model batteries of electric automobile case specific as follows:
First, the outer surface of described battery case can be handled (promptly forming the electrostatic plastic spraying layer) through electrostatic plastic spraying, the inner surface of battery case can increase insulation fire resistant coating or flame-retardant materials, loam cake 1 is provided with the position that contacts with battery pack 2 in the described battery case and is provided with insulated part, to maintain the insulation relation with battery pack 2.
The second, described battery case has increased several nylon roller 7 timely roller installing racks 8: because the batteries of electric automobile case is heavier at present, generally needs four people to lift, and need overcome very big frictional force, could drag it or spur.In order to overcome this shortcoming, increase by two rows (or many rows') nylon roller 7 in the bottom of the utility model battery case, forwardly also increase by two handles 12, be convenient to dismounting and mobile, greatly reduce the input of manpower, also realized simultaneously the insulation of battery case and car load, guaranteed the security performance of car load, made that dilatory battery is more convenient.
The 3rd, described battery case has increased alignment pin 10 and has located mutually with vehicle body: be provided with several dowel holes at the rear portion of battery case, in vehicle body, be provided with several location holes with it supportingly, the utility model has designed two pairs of alignment pins 10, simultaneously between battery case and vehicle body, also be provided with two pairs of cushion blockings 9, to carry out vibration damping.
The 4th, the battery case front portion has increased by two pairs of installing racks 11, installs with vehicle body, can keep like this linking together with vehicle body, guarantees that battery case is not from the battery compartment landing.This installing rack and vehicle body have insulating mounting, have increased the fail safe of vehicle.In addition, described battery case has self-locking structure, and under the situation of energising, battery case can be not voluntarily from the landing of car storehouse, guarantees the fail safe of car load.
The 5th, described battery case has increased the installation of battery management system (BMS) capture card 5 and fuse 6: the battery for electric automobile case generally all is placed on the chest the inside to battery management system capture card and fuse at present, at set intervals to the maintenance of each parts of battery case, add a lot of collection lines is arranged on the BMS, the maintenance not aspect of getting up very, the man power and material who expends is bigger.In order to overcome this shortcoming, putting into the outside with the acquisition module of fuse battery management system, fundamentally the aspect is overhauled and is changed.Shorten the time of safeguarding so greatly, be convenient to regularly battery be safeguarded.
The 6th, increase heating-cooling device in the described battery case: the used battery of electric automobile mostly is ferric phosphate lithium cell greatly at present, and the ferric phosphate lithium cell flash-over characteristic is relatively good, do not produce blast, stablize, characteristics such as cycle-index height are extensively accepted by industry, but there is bigger restriction at low temperatures in the performance of lithium ion battery (for example ferric phosphate lithium cell), the about 60-70% of capability retention in the time of 0 ℃, capability retention is about 40-55% in the time of-10 ℃, capability retention is about 20-40% in the time of-20 ℃, and such cryogenic property obviously can not satisfy the instructions for use of electrical source of power.Especially external or the Domestic Environment temperature is quite low at some, because the reason of battery, electric automobile is difficult to work.So need treat that temperature stabilization is good to the preheating of carrying out of battery, electric automobile can normally use, and does not influence traffic like this; On the contrary, if the lithium ion battery temperature is under the situation of high temperature, though car energy cruising has reduced the cycle life of battery pack greatly, thereby influenced the mileages of continuation of electric automobile.The utility model is by being provided with heating-cooling device, in time battery being carried out preheating or cooling, thereby guarantees the normal use of battery.
Therefore, because the battery case of this electric automobile comprises air inlet 3 and air outlet 4, and air inlet is provided with air strainer, can play dustproof effect well by this air strainer, the air outlet place of this battery case is provided with the powerful cooling fan 13 of number row simultaneously, force to pass in and out wind by this cooling fan 13, distribute heat well, play cooling effect, thereby the battery case of electric automobile of the present utility model not only has the good dust-proof effect, and the heat that in use produces can access effective release.In addition, in the optimal way of the utility model battery case, that battery case provided by the utility model has is dustproof, the comprehensive function of fire prevention, insulation, vibration damping.
Each concrete technical characterictic described in above-mentioned embodiment can carry out combination in any by any suitable manner, and it falls within the scope disclosed in the utility model equally.In addition, also can carry out combination in any between the various execution mode of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.Below describe preferred implementation of the present utility model in conjunction with the accompanying drawings in detail; but; the utility model is not limited to the detail in the above-mentioned execution mode; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection range of the present utility model.Protection range of the present utility model is defined by the claims.
