Abstract
The invention provides a cylindrical unit cell parallel connection method for the society. A plane of a parallel frame obtained by stretch-forming a metal sheet is provided with a plurality of stretching round holes in clearance fit with the diameters of cells, and a plurality of shrapnels in interference fit with the diameters of the cells are arranged in the periphery of the stretch round holes. The cells are installed in the stretch round holes of the parallel frame, so the relative position of each of the cells in a parallel loop can be accurately restricted, and the shrapnels of the stretch round holes can ensure the parallel contact reliability of each of the cells in the parallel loop; and the frame can balance the temperature difference of each of the cells in a banked cell pack can be balanced by using the thermal conduction of the metal frame, and can also have a heat radiation assisting efficacy. The flange of the parallel frame can be provided with a plurality of outwardly-projecting arc-shaped wafers, so the cell pack can be in parallel with an adjacent cell pack through the wafers.
Description
Technical field:
The present invention relates to a kind of cell parallel method of attachment of battery pack, be specially adapted to cylindrical cell and be connected in parallel and method.
Background technology:
More jumbo battery pack conventionally all need to be by the realization that is connected in parallel of a plurality of cells, and cell parallel connected mode is not only related to the packaging efficiency of battery pack, and affects basic mechanical design feature, useful life and the fail safe of battery pack.The parallel way of current battery adopts bar shaped or netted conducting strip to be welded on the electrode of battery conventionally, and the positive pole/negative pole of shunt circuit all batteries is linked together by conducting strip.Do so not only group technology complexity, dismounting battery is more difficult, and has product quality and potential safety hazard.
Summary of the invention:
The object of the invention is: a kind of new cylindrical cell method that is connected in parallel is provided, and battery is installed for its and dismounting battery is very convenient, can guarantee the reliability of cell parallel contact.
Technical scheme of the present invention is: adopt framework in parallel of sheet metal stretch forming, surrounding has fillet and flange, in the plane of framework in parallel, have the diameter of several and battery to be the stretching circular hole of matched in clearance, the surrounding of stretching circular hole has the diameter of several and battery to be the shell fragment of interference fit.Battery is arranged in stretching circular hole, can limit exactly the relative position of each battery in shunt circuit, several shell fragments of stretching circular hole stick on battery outer wall tightly, so not only can guarantee that in shunt circuit, each cell parallel contact is reliable, utilize the heat conductivity of metal battery outer wall and parallel connection of metals framework, framework in parallel can balance batteries in parallel connection group in the temperature difference of each battery, also can conduct to the outside the heat that battery produces by parallel connection of metals framework.
On the flange of framework in parallel, can process the circular arc contact of several outwardly convexs, can be in parallel with adjacent battery pack by contact.
Advantage of the present invention is: a kind of new cylindrical cell method that is connected in parallel is provided, stretching circular hole on framework in parallel can limit the relative position of each battery in shunt circuit exactly, and the shell fragment of stretching circular hole can be guaranteed the reliability of each cell parallel contact in shunt circuit.Not to the utmost and this utilizes the heat conductivity of parallel connection of metals framework, framework in parallel can also balance batteries in parallel connection group in the temperature difference of each battery, also can conduct to the outside the heat that battery produces by parallel connection of metals framework.On the flange of framework in parallel, can process the circular arc contact of several outwardly convexs, can be in parallel with adjacent battery pack by contact.
Accompanying drawing explanation:
Fig. 1 is the stereogram of cylindrical cell framework in parallel;
The contact that Fig. 2 is two groups of adjacent battery pack by framework in parallel connects the front view being connected in parallel;
Wherein: 1. framework in parallel, 2. circular hole, 3. shell fragment, 4. flange, 5. contact, 6. fillet, 11. batteries, 12. anode fixtures.
Embodiment:
Below in conjunction with drawings and Examples, the present invention is further described:
Embodiment 1: the framework in parallel (1) that adopts sheet metal stretch forming, surrounding has fillet (6) and flange (5), in the plane of framework in parallel, have several that stretching circular hole (2) of battery is installed, stretching circular hole surrounding has 8 shell fragments (3), guarantees to have good contacting with battery; On the flange of framework in parallel, can process the circular arc contact (5) of 3 outwardly convexs.
42 cylindrical batteries (11) are arranged on to (1) on framework in parallel, and anode fixture (12) is fixed on anode top.Form thus a battery pack that Capacity Ratio is larger.
If two groups of assembled batteries need to be connected in parallel, only two groups of assembled batteries need to be put together side by side, the contact of two frameworks in parallel (5) links together, and just can realize the parallel connection of two groups of assembled batteries.
Claims (3)
1. the cylindrical cell method that is connected in parallel, it is characterized in that: the framework in parallel that adopts sheet metal stretch forming, surrounding has fillet and flange, in the plane of framework in parallel, have the diameter of several and battery to be the stretching circular hole of matched in clearance, the surrounding of stretching circular hole has the diameter of several and battery to be the shell fragment of interference fit.
2. utilize the heat conductivity of metal battery outer wall and parallel connection of metals framework, framework in parallel can balance batteries in parallel connection group in the temperature difference of each battery, also can conduct to the outside the heat that battery produces by parallel connection of metals framework.
3. the cylindrical cell according to claim 1 method that is connected in parallel, is further characterized in that: on the flange of described framework in parallel, can process the circular arc contact of several outwardly convexs, and can be in parallel with adjacent battery pack by contact.
