Abstract
A switching board for assembly of a soft package lithium ion battery is provided. Orderly arranged long stripped holes are provided on the board, a welding area with a metal coating layer is provided on a same side board surface around the long stripped hole; the switching board can be provided with a battery managing system signal wire interface and a printing circuit connecting the welding area with the corresponding interfaces. The utility model is used for assembling soft package lithium ion battery, penetrates single body battery pole ear through the stripping hole for welding and fixing in the welding area without wire connecting, thereby realizing the purpose of battery connected in serial or in parallel, the battery has small resistance, the welding has few times, the battery assembly efficiency and qualified rate can be improved and the false signal wiring of battery managing system can be avoided, as well as the battery application performance can be ensured.
Description
Technical field
The utility model relates to a kind of parts of battery assembling usefulness, especially lithium ion battery pack dress keyset.
Background technology
The assembling of current battery group mainly is that the mode by parallel connection increases the capacity of battery pack and increases the voltage of battery pack by the mode of series connection.Along with the raising of the security performance of lithium ion battery and the reduction of cost, the high capacity of lithium ion battery and Towards Higher Voltage will be trends of the times.
In the series-parallel actual mechanical process of lithium ion battery pack, in order to reach series-parallel purpose, to couple together with lead between the battery pole ear, Zu Zhuan battery pack internal resistance is big in this way, lead connects complicated, welding times is many, efficient is low, and assembling process causes that easily the short circuit between the battery takes place.And battery pack in actual use, to control battery with battery management system toward contact, battery management system must be gathered the parameters such as voltage, electric current of each cell by holding wire.The situation that in the process of welding signal line respectively, occurs at present the holding wire wrong easily, thereby battery management system and battery pack are caused damage, and along with the increase of battery strings quantity in parallel, it is more and more obvious that the problem of existence can become, and has a strong impact on the battery serviceability.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art part, provides a kind of and can reduce the internal resistance of cell, improves the packaging efficiency and the qualification rate of battery, guarantees the lithium ion battery pack dress keyset of battery serviceability.
The technical solution of the utility model is: this keyset is a plastic plate, and plastic plate is provided with the strip hole of proper alignment, and the same lateral plates around the strip hole is provided with the weld zone that has the coat of metal.
Further scheme is: keyset is provided with printed wire, and the edge of keyset is provided with the battery management system signal wire interface, and above-mentioned each weld zone is connected with the corresponding signal lines interface by printed wire respectively.
The utility model is used for the assembling of flexible packing lithium ion battery, during operation, keyset is placed on the top of the cell of arranging by the serial or parallel connection mode, corresponding strip hole on the keyset is upwards passed with the lug of each battery in the side that keyset has a weld zone, and is welded on the coat of metal around the hole, lug is fixed like this, corresponding lug is directly welded together, does not need lead to connect, and just can reach the purpose of serial or parallel connection.Adopt the battery pack internal resistance of keyset assembling little, welding times is little, can not cause the short circuit between the battery, improves the packaging efficiency and the qualification rate of battery.Simultaneously, the printed wire that can be provided with the battery management system signal wire interface and connect each weld zone and the corresponding interface on the keyset when making battery pack assembling management system, the situation of holding wire wrong can not occur, avoid fault, further guarantee the battery serviceability.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 has the structural representation of printed wire and signal wire interface for the utility model.
Embodiment
See accompanying drawing, it is sheet material that the lithium ion battery pack dress adopts hard plastic board with keyset 1, plate is provided with the strip hole 2 of proper alignment, same lateral plates around the strip hole is provided with the weld zone 3 that has the coat of metal, the printed wire 5 that also can be provided with battery management system signal wire interface 4 and connect each weld zone and the corresponding interface on this keyset, the application example of keyset is as follows:
Example one: get 4 cell B
1～B
4Vertically sequence, wherein the positive and negative lug B of each battery
1 +, B
2 -, B
3 +, B
4 -Form a line and align B
1 -, B
2 +, B
3 -, B
4 +Form a line and align, the keyset that is provided with 8 strip holes and is provided with corresponding printed wire and signal wire interface is placed on the cell top, the weld zone up, the positive and negative lug of each battery passes behind the corresponding strip hole fixing with the weld zone welding around this hole respectively, again with B
1 +With B
2 -, B
2 +With B
3 -, B
3 +With B
4 -Be welded into one after the bending respectively, so just be assembled into the series battery of 4 cells that can directly be connected with battery management system.
Example two: get 4 cell B
1～B
4Vertically sequence, wherein B
1 +, B
2 +, B
3 +, B
4 +Form a line and align B
1 -, B
2 -, B
3 -, B
4 -Form a line and align, the keyset that is provided with 8 strip holes is placed on the cell top, the weld zone up, B
1 +, B
2 +, B
3 +, B
4 +After passing strip hole respectively, all bending and weld zone are welded into one B jointly
1 -, B
2 -, B
3 -, B
4 -After passing strip hole respectively, all bending and weld zone are welded into one jointly, so just form the batteries in parallel connection group of 4 cells.
