Abstract
The invention discloses a power battery thermal management method, and relates to the technical field of usage of power batteries. A thermal management channel provided with an entrance and an exit is arranged in a battery barrel body; a cooling and heating device arranged at the entrance is used for respectively enabling cold fluid and heat fluid to pass through the channel as required, so battery thermal management within small range is implemented; and the thermal management channel can be communicated or isolated with a battery inner cavity. The method is applied to thermal management of power batteries, and has the advantages that: occupied space is small, power consumption is low and efficiency is high, all batteries can be well managed, and the performance of the whole groups of batteries is effectively improved.
Description
Technical field
The present invention relates to the use of electrokinetic cell, relate to a kind of electrokinetic cell thermal management algorithm specifically.
Background technology
Advocate green energy resource in recent years in the global range energetically, the development of new-energy automobile is subjected to national governments and supports energetically, the development of electrokinetic cell is also fiery unusually, but because the technology of current battery limitation, temperature influence causes the situation of decreased performance comparatively obvious in the use of electrokinetic cell, as: the performance of battery charging and discharging capacity reduces greatly under the low temperature condition; Can quicken the aging of electrolyte volatilization, pole piece during high temperature and reduce useful life of battery, selecting preferably, the heat management mode is the problem that needs research with the performance that improves battery.
The heat management mode of current battery is according to the difference of application, and selection mode is also had nothing in common with each other.The back-up source field generally is to adopt standby some power supplys are assemblied in the airtight warehouse, the warehouse somewhere is provided with cooling unit and heating unit, and heating and cooling are carried out in the battery pack inner space, and this kind mode is bigger because of the heat management space, heat management unit power consumption is bigger, and DeGrain.There is not battery thermal management in little mixed light mixing on the vehicle in the electrical source of power field, causes the performance of battery to reduce; Mostly on the complete mixed pure electric vehicle adopt that whole group is air-cooled, the modes of liquid cooling, often can not be with respect to every battery, wherein one or the reduction of part battery performance can have influence on the performance of whole Battery pack.
Summary of the invention
The purpose of this invention is to provide that a kind of power consumption is little, heat management efficient height, can be with respect to the electrokinetic cell thermal management algorithm of every battery.
Technical scheme of the present invention is: reserve the heat management passage that has entrance and exit in the staving of battery case, cooling by being arranged on the porch and heater make the cold and hot fluid above-mentioned passage of flowing through as required respectively, implement battery thermal management among a small circle.
Further scheme is: described heat management passage and battery intracavity inter-connection, used fluid are gas; In the heat management passage, deep bead is set, makes gas oriented and ordered mobile; Perhaps described heat management passage and battery inner chamber are isolated, and used fluid is gas or liquid.
The present invention utilizes flow through reserved passageway in the battery staving of cold and hot fluid, perhaps make hot and cold gas directly enter the electric core groove of battery inner chamber, single battery is carried out heat management among a small circle, it is little to relate to the space, low in energy consumption, heat management efficient height can guarantee the normal working temperature of every battery, thereby improves the performance of whole Battery pack.Can fan be set in the inlet or the exit of reserved passageway, increase the flow velocity of gas, also can in passage, increase deep bead in the relevant position, make gas oriented and ordered mobile, further improve heat management efficient; Also can seal entry and exit as required, make the inside battery insulation.
Description of drawings
Fig. 1 is battery staving gas passage schematic diagram among the present invention;
Fig. 2 is battery staving fluid passage schematic diagram among the present invention.
Embodiment
Embodiment 1: referring to Fig. 1, heat management passage 2 is reserved in inside at electrokinetic cell staving 1, this passage is connected with battery inner chamber 4, needs according to battery operated temperature, cooling by being arranged on inlet 3 outsides and heater makes cold respectively or hot gas (air) from inlet advance, through the heat management passage, and the battery inner chamber of flowing through, flow out from exporting 5 again, extraction fan is established in the exit, corner at the close position, entry and exit of heat management passage is respectively equipped with deep bead 6, make gas by among the figure shown in the arrow, oriented and ordered flowing.
Example 2: referring to Fig. 2, heat management passage 8 is reserved in inside at electrokinetic cell staving 7, this passage and battery inner chamber 9 are isolated, place's sealing state, according to the needs of battery operated temperature, the cooling by being arranged on inlet 10 outsides and heater makes cold respectively or hot liquid (purifying waste water) advances from inlet under certain pressure, through the heat management passage, flow out from exporting 11, and reclaim and reuse, arrow is depicted as flow direction among the figure.
Claims (4)
1. electrokinetic cell thermal management algorithm, it is characterized in that in the staving of battery case, reserving the heat management passage that has entrance and exit, cooling by being arranged on the porch and heater make the cold and hot fluid above-mentioned passage of flowing through as required respectively, implement battery thermal management among a small circle.
2. by the described electrokinetic cell thermal management algorithm of claim 1, it is characterized in that described heat management passage and battery intracavity inter-connection, used fluid is a gas.
3. by the described electrokinetic cell thermal management algorithm of claim 2, it is characterized in that in the heat management passage, deep bead being set, make gas oriented and ordered mobile.
