Description
Technical field
The utility model relates to a kind of folding Soft Roll power battery pack.
Background technology
At present, the connection of Soft Roll power battery pack lug is all adopt screw to connect (to there is internal resistance large, complicated operation, connect the phenomenons that may occur such as loosening), soldering connects (to be existed temperature height when welding and easily hurts battery core, easily come off during scolding tin high temperature, welding rosin joint etc.) electrode of Soft Roll monomer battery core directly connects serial or parallel connection and becomes battery pack by (cost the is high) mode that is connected with Laser Welding, because above-mentioned connected mode is all Hard link, therefore require strict in the process of Soft Roll monomer battery core formation battery pack to the consistency of Soft Roll monomer battery core and internal resistance, but existing Soft Roll monomer technology for manufacturing electric core, Soft Roll monomer battery core consistency is poor, and the consistency of Soft Roll monomer battery core will be ensured, then need the screening technology increasing Soft Roll monomer battery core complexity, cost is made greatly to improve like this, if and Soft Roll monomer battery core consistency is poor, then make Soft Roll monomer battery core the series/parallel of routine connect into battery pack time internal resistance bigger than normal, when causing connection, temperature is too high, thus to the damage that battery causes, and bring potential safety hazard to the battery pack after combination.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art and provide a kind of structure simple battery pack, and this novel be a kind of replaceable monomer battery core and folding Soft Roll power battery pack easy to maintenance.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of folding Soft Roll power battery pack, comprise multiple Soft Roll monomer battery core, each described Soft Roll monomer battery core is equipped with two lugs, by conductor series connection or parallel connection between multiple described Soft Roll monomer battery core, described conductor with between Soft Roll monomer battery core for welding, described conductor is the conductor of flexible folding material.
Series connection group is formed after multiple described Soft Roll monomer battery core series connection; the Soft Roll monomer battery core of described series connection group is folded to form rectangle along conductor; electrode one end of described series connection group after folding is provided with insulating protecting plate, and described insulating protecting plate is provided with the protective sleeve matched with group electrode position of connecting.
Described insulating protecting plate is supported in Soft Roll monomer battery core by collets, prevents external force from acting directly on the lug of Soft Roll monomer battery core.
Described series connection group is in parallel with group of connecting and be provided with insulation board between adjacent described series connection group.
Described conductor is copper strips, aluminium strip or nickel strap.
Owing to adopting such scheme, the electrode of multiple Soft Roll monomer battery core is connected by the mode of welding or/and in parallel by conductor by this device, and conductor employing is soft material, not directly by the Electrode connection of Soft Roll monomer battery core, cell for convenience detach and monomer replacement in maintenance can be made like this, cell adopts this welding manner, make welding more firm, avoid the bad phenomenon such as loose contact that high temperature comes off or between tin stream and battery, screw compresses mode that conventional soldering connects, this mode is less than conventional connected mode battery pack internal resistance, specific power is large, workable, conveniently automated production can be realized, when preventing connection, temperature is too high simultaneously, add the security performance of battery, and after the series connection of Soft Roll monomer battery core, due to the material that conductor is flexible folding, battery pack after such series connection can fold, make the size controllable of battery pack, therefore applied range.
Accompanying drawing explanation
Structural representation when Fig. 1 is the utility model expansion.
Fig. 2 is the structural representation after the utility model folds.
In figure, 1. Soft Roll monomer battery core, 2. conductor, 3. lug, 4. insulating protecting plate, 5. protective sleeve.
Embodiment
Below in conjunction with accompanying drawing, further describe the embodiment of this patent.
As Fig. 1, shown in 2, a kind of folding Soft Roll power battery pack, comprise multiple Soft Roll monomer battery core 1, each described Soft Roll monomer battery core 1 is equipped with two lugs 3, by conductor 2 serial or parallel connection between multiple described Soft Roll monomer battery core 1, described conductor 2 with between Soft Roll monomer battery core for welding, described conductor 2 is the conductor of flexible folding material, multiple described Soft Roll monomer battery core 1 forms series connection group after connecting, the Soft Roll monomer battery core of described series connection group is folded to form rectangle along conductor, electrode one end of described series connection group after folding is provided with insulating protecting plate 4, described insulating protecting plate 4 is provided with the protective sleeve 5 matched with group electrode position of connecting, described insulating protecting plate 4 is supported in Soft Roll monomer battery core 1 by collets, prevent external force from acting directly on the lug of Soft Roll monomer battery core, described series connection group is in parallel with group of connecting and be provided with insulation board between adjacent described series connection group.
The step that concrete technology makes is as follows:
A, adjust the arranging distance of Soft Roll monomer battery core, get out the copper strips of correspondingly-sized, aluminium strip or nickel strap;
B, good Soft Roll monomer battery core loaded in fixture be well placed, and be well placed series connection copper strips, aluminium strip or nickel strap in lug position;
C, by welding head, connecting welding is carried out to lug and copper strips, aluminium strip or nickel strap, complete the assembled in series of battery;
D, the Soft Roll monomer battery core connected is converted into the series connection group of required specification and size, installing insulating baffle, if need parallel connection, more multiple series connection group is in parallel, and insulation board is set between adjacent string joint group.
Above-mentioned cell series/parallel is become modular battery group, and the copper strips welded from the total positive pole of battery pack and total negative pole or nickel strap need the corresponding size of reservation and position so that draw according to being connected.
With this device, electrokinetic cell cell series/parallel is become battery pack, its internal resistance is little, specific power is large, workable, can realize automated production, its internal resistance just connects by this mode and effectively decreases internal resistance of cell resistance, ensure that battery with two side terminals, add the security performance of battery.
