Abstract
The invention discloses a soft-packaged dynamic lithium battery group, comprising: multi-section soft-packaged lithium batteries (5) provide high voltage to the automobile by connecting in series, each soft-packaged lithium battery is placed between two heat emission metal channels (3) which has a through hole in the center and flats on the two ends, placing the assembly in a battery group outer case (2) and filling silicon rubber (6), the air get into the heat emission metal channel (3) central through hole from the air inlet located in the bottom corner of the group outer case (2) and out from the air outlet.
Description
Technical field:
The present invention relates to a kind of power battery of electric vehicle group, this battery pack provides high piezoelectric voltage by a plurality of flexible package lithium cell series connection, the vent passages that between the lithium electricity, has heat radiation, and perfusion silicon rubber, more specifically, relate to a kind of stable performance, have the heat dissipation ventilation road, can aging-resistant flexible packaging power lithium battery group.
Background technology:
Lithium battery has been widely used in many fields, particularly as power battery of electric vehicle as a kind of novel pollution-free secondary cell.At present the nominal voltage of the single lithium battery of using is generally 3.6V, and the battery pack that the is used for electric motor car above single lithium battery of 80 joints of need connecting directly is put in after the series connection in the casing.Closely be arranged in together between all single lithium battery, heat distributes when being unfavorable for that the lithium electricity discharges and recharges, and heat accumulation can lower battery life around battery.And electric motor car is to walk on different road surfaces, can certain vibrations be arranged to battery, and this vibrations can make the connection of battery loosening usually, can get loose when serious, and vibrations also has damage to battery itself, particularly the flexible packaging power battery.
Summary of the invention:
The purpose of this invention is to provide a kind of flexible packaging power lithium battery group, its have connect stable, thermal diffusivity is good, good airproof performance, can anti-aging effect.
In order to reach the above-mentioned purpose of invention, the lug of each single lithium battery all has a circular hole, make the lug conducting of its two battery by a copper bar and copper pipe, and be screwed in nut and lock lug on the copper bar, the copper pipe or the aluminium alloy of good heat dissipation arranged between two single lithium battery, copper pipe or aluminium alloy have through hole, communicate with air duct about the battery, the battery pack body that connects is put into the battery pack outer container, and perfusion has the silicon rubber of elasticity and energy heat conduction to be fixed, and plays sealing function simultaneously.
Description of drawings:
Fig. 1 represents the embodiments of the invention generalized section;
Fig. 2 represents each air channel of battery pack of the present invention and bottom support;
Fig. 3 represents battery combination mode of the present invention;
Fig. 4 represents that copper pipe of the present invention is as heat radiating metal combination of channels mode.
Among the figure: battery pack outer container top cover 1 battery pack outer container 2 heat radiating metal passages 3 contact tubes 4 nuts 4.1 copper pipes 4.2 copper bars 4.3 flexible package lithium cells 5 silicon rubber 6 support 11 fens air channel 12 sealing copper sheets 13 of 7 connecting plates, 8 lugs, 9 collection air channels, 10 main air ducts
Embodiment:
Copper pipe is arranged in a row, two plumbers shed spot welding, make in aggregates, flatten and stick one respectively and seal copper sheet 13 on its both sides, making copper pipe row is a plane with flexible package lithium cell 5 contact-making surfaces, flow into main air duct 11 and branch air channel 13 when preventing to weigh wounded flexible package lithium cell 5 and irritating silicon rubber 6, its integral body is as heat radiating metal passage 3.Or be the plane with being shaped to the two sides, the good sheet metal of the thermal conductivity of hollow, as aluminium alloy as heat radiating metal passage 3.Heat radiating metal passage 3 is arranged in parallel, the connecting plate 8 of burn-oning in two heat radiating metal passages, 3 lower ends, make and form a space of just loading a joint monomer flexible package lithium cell 5 between the two heat radiating metal passages 3, pass positive pole ear 9 holes of a flexible package lithium cell 5 with conductive copper bar 4.3, put copper pipe 4.2 again, last negative lug 9 holes of passing another flexible package lithium cell 5 again, the copper pipe 4.3 that is put in 5 of two flexible package lithium cells plays two lugs, 9 effects of supporting, be screwed into nut 4.1 on the screw thread at copper bar 4.3 two ends, locking lug 9, be with a spring meson at nut 4.1 and 9 of lugs, with the effect of fixing.The flexible package lithium cell 5 of so connecting forms a battery pack body.Many supports 7 are fixed on the following inner surface of battery pack outer container 2, the battery pack body is put and will be supported on 7, supports 7 and just in time is close to connecting plate 8, plays the support cells effect, just form the air duct of hollow with the three, this air duct communicates with the ventilation hole of air inlet and heat radiating metal passage 3.The silicon rubber 6 that perfusion has elasticity and thermal conductivity; be filled in all non-vent passages; perfusion is to the interior good following 5MM of conduction circular hole that there was not battery pole ear 9; battery is sealed in the silicon rubber 6 fully; protecting lug 9 to connect simultaneously gets loose; and can prevent that also extraneous liquid or gas from corroding flexible package lithium cell 5, has sealing function.Because of silicon rubber 6 has elasticity,, flexible package lithium cell 5 had protective effect so in the electric motor car driving process, play cushioning effect.Perfusion silicon rubber 6 upper surfaces are just equal with heat radiating metal passage 3, and the upper surface of silicon rubber 6 and battery pack outer container top cover 1 and battery pack outer container 2 form a collection air channel 10, and this collection air channel 10 communicates with the ventilation hole of air outlet and heat radiating metal passage 3.From air inlet, main air duct 11 enters branch air channel 12 below the battery pack body, enters the through hole of the heat radiating metal passage 3 of 5 of flexible package lithium cells again, takes away the heat that sends when flexible package lithium cell 5 discharges and recharges, enter the collection air channel 10 of silicon rubber 6 upper surfaces again, be drawn out of from air outlet.
