Background technology
Along with the day of whole world petroleum-based energy is becoming tight; Electric motor car and hybrid vehicle have become the domestic focus development project of automobile vendor that is; As new-energy automobile, its market value and technology content all are the highest, and wherein electrokinetic cell is that motor provides energy; Motor is that car load provides power, guarantees automobile normal running.And working power battery greatest problem is its life-span and service behaviour, because of the electrokinetic cell working temperature requires than higher; Promptly 10 ℃～45 ℃., actual work temperature just has a strong impact on the useful life and the service behaviour of battery when surpassing 10 ℃～45 ℃ scope.The employed electrokinetic cell of domestic new-energy automobile of present stage all adopts the wind-cooling heat dissipating system, makes the air in the environment flow through the electric core of lithium battery and take away its heat through forced convertion, and the assurance battery is worked in certain temperature range.Its shortcoming is that air themperature depends on extraneous ambient temperature; When ambient temperature changes (for example exchange in season); The cooling effect of battery also changes thereupon, causes the uniformity of battery operated temperature and heat load unstable, thereby influences the service behaviour and the useful life of battery.
Summary of the invention
The purpose of the utility model provides a kind of motor vehicle electrokinetic cell of controlled working temperature.
The purpose of the utility model is achieved in that it includes power brick vanning, battery, battery control device, heat exchange fan; It is characterized in that: the top cover inner face of power brick vanning is provided with the heat exchange fan; In the power brick vanning of heat exchange fan downside, be provided with battery; Power brick vanning bottom at the battery downside is provided with heat-conducting plate, in heat-conducting plate inside refrigerant pipe and hot-water line is arranged, and also is provided with high-voltage line and low-voltage line interface on the battery control device.
Described battery is the lithium battery core.
Be provided with the conducting strip of lower end bending between the described battery, this conducting strip is connected with heat-conducting plate.
Described battery is distributed in two electric core modules at least, and this electricity core module is arranged in the power brick vanning of heat exchange fan downside.
The cold and hot temperature of the utility model is all controlled, so no matter be winter or summer, battery can both be stable for motor provides energy, guarantee the normal startup of car load and goes.The main thermal source and the low-temperature receiver that add gentle heat radiation all come from the on-board air conditioner pipeline, have avoided air-cooled structure because of passing in and out dust and the impurity that bring in the air channel, thereby have reduced the application risk of battery, the useful life of having improved battery.Between electric core, increase conducting strip, improved the uniformity of the heat load of battery battery core, guaranteed the consistency of battery battery core performance.
