Description
Technical field
The utility model belongs to the electric vehicle engineering field, is specifically related to a kind of cooling system of electric automobile power battery group.
Background technology
Increasingly serious along with the energy and environmental problem, the electric automobile that occurs as the environment-friendly and energy-efficient automobile, important milestone in the automobile industry beyond doubt.Electric automobile is being owing to have aspect energy efficiency and the reduced exhaust than the better advantage of conventional truck, thereby obtains worldwidely generally paying attention to.But the performance of these vehicles and quality rely on unfailing performance, cycle performance and the cost etc. of the performance of the battery pack that it disposed, particularly battery to a great extent.In fact, battery is as the energy storage device element, it can produce electric reaction heat and Joule heat when discharging and recharging, and heat meeting and other factors (battery variety, battery operation operating mode, the type of cooling and battery-arrangements mode etc.) influence the variation of battery temperature jointly.And in electric automobile, electrokinetic cell all uses in groups, variation of temperature will certainly make and have certain temperature difference opposite sex between the battery, this temperature contrast mainly influences the bulk life time and the stability of battery pack, because high temperature can quicken electrolyte, the rate of ageing of electrode and dividing plate, when the temperature difference in the battery pack is big, the rate of ageing of high-temperature part can be obviously faster than the low temperature part, along with the physical difference between the different batteries of the accumulation of time will be all the more obvious, thereby destroyed the consistency of battery pack, cause the performance between the cell not match, whole Battery pack was lost efficacy in advance, directly have influence on the performance of electric automobile.Traditional air cooling system is because the existence of air inlet and air outlet must cause the decline of classification of waterproof, and water-cooling system involves great expense, weight is big simultaneously.Therefore, the optimal design of electrokinetic cell cooling system is the assurance of the good operation of battery pack, and it restricts the development of electrokinetic cell to a great extent and applies.
Summary of the invention
For bulk life time and the stability that solves the battery pack that the temperature contrast between the battery causes in the power battery pack, thereby influence problems such as vehicle performance, the utility model provides a kind of power battery device with air-cooled mechanism that is used for electric automobile that improves structure.
It is as follows that concrete structure of the present utility model improves technical scheme:
The power battery device with air-cooled mechanism that is used for electric automobile comprises Battery case and battery, and the middle part is provided with every inner panel in the described Battery case, makes and forms two battery chambers in the Battery case; The middle part is provided with two desk fans that blowing direction is opposite, power is identical side by side in each battery chamber, and described battery is uniform to be arranged in the battery chamber of two desk fan both sides.
Described fan is an axial fan, power 10W～30W.
Useful technique effect of the present utility model embodies in the following areas:
1, the utility model adopts hermetically sealed design, and no air inlet and air outlet have improved the water resistance of air cooling system greatly;
2, the utility model requisite space is little, and device cost is low, is fit to very much the economy electrocar and uses;
3, the utility model internal difference in temperature is little, guarantees the consistency of battery operated ambient temperature, improves the working life of electrocar electrokinetic cell; Improve the discharge performance of electrokinetic cell; The dynamic property that support vehicles are stable;
The heat radiation of the air flows on chassis improved capacity usage ratio when 4, the utility model utilized vehicle ', improved car load economy and fail safe;
5, the utility model is highly suitable for and carries out partial design on the existing diesel locomotive basis and develop electric automobile after changing, under the prerequisite that does not change the original passenger compartment of similar internal combustion engine space, battery case is arranged under the back seat, to guarantee the crew module space.Car load is changed little, and development cost is low.
