Description

A kind of power lithium-ion battery case temperature control circulation
Technical field
The utility model relates to a kind of battery case, refers specifically to a kind of battery case that has temperature control equipment.
Background technology
Along with the exhaustion of petroleum resources and the raising of people's environmental consciousness, be that the pure electric automobile of power is subjected to more and more people's attention with the lithium ion battery.At present, automobile production both domestic and external manufacturer, battery manufacturers and each research institution all drop into the research that a large amount of funds carry out automobile power cell.In general in order to satisfy the automobile power needs, automobile-used lithium-ion-power cell need have bigger power output and discharge performance.Because battery itself has certain internal resistance (generally about 5-20m Ω), under the operating state of the big electric current output of battery,, suppose that output current is 50A according to Ohm's law, internal resistance of cell 10m Ω, then each battery was emitted heat Q=I in 1 minute 2Rt=50 2* 0.01*60=1500J, and management for the ease of BMS, generally be that tens 20 batteries are placed in the battery case, simultaneously because battery case generally adopts hermetically-sealed construction, the heat that battery produces can not in time distribute, very easily cause the operational environment of high temperature, and the safe working temperature of general battery is 0-80 ℃, surpasses the safe temperature battery and blast easily.Therefore, how to control temperature minimizing potential safety hazard and become lithium ion battery applications in the primary bottleneck that solves of automotive field.
Patent 200920172818.6 has designed a battery case with refrigerating function, and casing is a cuboid band shell structure, case and outer container in comprising, and, mainly use Design of ventilation to reach the order ground of cooling at internal layer use insulation board.But, the summer temperature in most of area, China south is generally more than 35 ℃, the pavement temperature of highway even sometimes reach 60 degrees centigrade, under this temperature, the air themperature of sending into Battery case is higher, does not reach cool effect, therefore, good, the long service life of design cooling performance, cheap lithium-ion-power cell case are very important.
The utility model content:
In order to solve the problem that exists in the above technology, the utility model proposes with technical solution.
The utility model is by water inlet pipe 1, outlet pipe 2, cooling water 3, battery case 4, base plate 5 is formed, the casing of battery case 4 is the poly-structure of covering of cuboid, inner surface all posts insulating material, can be built-in the powerful lithium iron phosphate dynamic battery of two rows, its length and width height can adjust according to the size and the number of actual cell, whole box body is made of steel plate, be welded to connect by angle steel between each face, battery case casing front and back and right flank are double-layer sealing structure, the left surface of Battery case is a single layer structure, the top of battery case base plate is not have a side lid of air-vent, the interlayer width of double-layer sealing structure is according to fluid mechanics principle, specific heat capacity and thermal transmission coefficient in conjunction with cooling liquid, the flow velocity of interlayer cooling water 3 and the factors such as temperature control effect that need reach are carried out computer simulation analysis, are 2.4-4.5cm through calculating the interlayer width, and recirculated cooling water 3 flows into from the bottom water inlet pipe 1 of left surface, flow out from the top outlet pipe 2 of left surface, this design can reach maximum cooling-down effect.Temperature-controlling system comprises cooling fluid, water pump, water tank and water pipe, and the circulation circuit of recirculated cooling water 3 is water tank → water pump → battery case → water tank, and the left side of casing is the installation region of electric power connection line, temperature control system and BMS data acquisition unit.Base plate 5 is a single layer structure, the slideway that static housing is arranged in base plate 5 both sides, base plate is provided with osculum and air-vent, simultaneously in order to reach better temperature control effect, can the good radiator of heat dispersion be installed on the base plate 5 of battery case or heater is installed according to actual needs.Top board above the battery case 4 is the individual layer insulation system, simultaneously because battery is just put in the casing, electrode up, in order to prevent that conductive materials from entering casing and causing battery short circuit, the battery case top board has adopted the hermetically-sealed construction of no air-vent, thereby eliminates unnecessary potential safety hazard.
In the global design of battery case, the electricity consumption of working power water pump and radiator fan can provide by the working power battery, simultaneously in order to reach purpose of energy saving, water pump and radiator can separately be controlled, the battery temperature data decision that the driver can provide according to the BMS system is to open unify radiator or open one of them of cooling water system simultaneously, also can be according to the difference of environment for use, such as the north cold winter can change heater into.That is to say,, this battery case is normally used under various regions, all temps environment, enlarged the scope of application of battery case by in the heating of battery case bottom or the switching of heat abstractor.
The beneficial effects of the utility model are effectively to control the temperature in the battery case, are the south or the north no matter make lithium-ion-power cell, no matter be winter or summer, can both work in normal temperature range.
Description of drawings:
Figure (1) is a structural representation of the present utility model.
Embodiment:
The utility model is made up of water inlet pipe 1, outlet pipe 2, cooling water 3, battery case 4, base plate 5, as figure (1) when the battery operate as normal in the battery case 4, the BMS data acquisition unit is passed to temperature control system with the temperature regime signal of the battery case 4 that collected, and it is that needs heat up or cooling that temperature control system decides battery case 4 according to the height of the temperature of battery case 4.When battery case 4 temperature were higher, cooling water pump started, and the left bottom of cooling water 3 from battery case 4 pumped into, and cooling water flow is after the big calorimetric of steel plate absorption of battery case 4, from the left side top outflow of battery case 4.When battery case 4 internal temperatures are low when needing heating, heating pump starts, and adds hot water and flows to from the left side top of battery case 4, self heat is passed to the steel plate of battery case 4 after, flow out from the left bottom of battery case 4.In the cooling procedure of battery case 4, if cooling water does not reach when requiring the cooling effect of battery case 4, can be at the water-cooled air cooling system that starts simultaneously.
