Description
BATTERY ASSEMBLY FORMED BY PLURAL SOFT PACKING
SECONDARY BATTERIES
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a battery assembly, and more particularly to a battery assembly formed by plural soft packing secondary batteries.
Description of the Prior Art
Referring to Fig. 1, a conventional battery assembly comprises plural secondary batteries 10 and a corresponding number of fuses 11 that are assembled on a special rack 12.
When electric current exceeds a rated value due to failure of any one of the secondary batteries, the fuse connected to the failed secondary battery will be actuated to cut off the power, and the failed secondary battery will be isolated from other intact secondary batteries, preventing the failed secondary battery from causing the failure of the whole battery assembly.
It is to be noted that, each of the secondary batteries 10 in the above conventional battery assembly is 18650 packaged in a hard case.
Referring to Fig. 2, a conventional soft packing secondary battery is shown and has the advantages of light weight. Nevertheless, the current battery industry has not developed a feasible and safety design to allow a plurality of soft packing batteries to be packaged as a whole battery assembly and used together.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a battery assembly formed by plural soft packing secondary batteries which can improve the safety in use of the battery assembly.
To achieve the above objective, a battery assembly formed by plural soft packing secondary batteries in accordance with the present invention comprises plural soft packing secondary batteries in an accommodation space of a rack. The positive or the negative electrode of each of the soft packing secondary batteries is connected to a corresponding fuse in such a manner that each soft packing secondary battery is independently and directly connected to the corresponding fuse, forming a battery assembly using the positive conductive strip and the negative conductive strip as power output terminals. When electric current exceeds the rated value due to failure of any one of the soft packing secondary batteries, the fuse which is directly connected to the failed soft packing secondary battery will be actuated to disconnect the failed soft packing secondary battery from the positive or the negative conductive strip, so that the failed soft packing secondary battery can be isolated from other intact soft packing secondary batteries, thus improving the safety in use of the battery assembly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to Figs. 3-5, a battery assembly formed by plural soft packing secondary batteries in accordance with a preferred embodiment of the present invention essentially comprises a rack 30, plural soft packing secondary batteries 40, a positive conductive strip 50, a negative conductive strip 60, and plural fuses 70.
The rack 30 is formed with an accommodation space 31 surrounded by four side plates that are two longitudinal side plates 32 and two transverse side plates 33.
Each of the plural soft packing secondary batteries 40 includes a positive electrode 41 and a negative electrode 42 extending from an end thereof. The plural soft packing secondary batteries 40 are disposed in the accommodation space 31 of the rack 30. The positive electrodes 41 and the negative electrodes 42 are located at the top of the accommodation space 31.
The positive conductive strip 50 straddles the accommodation space 31 and includes two assembling ends 51 which are fixedly disposed on the two transverse side plates 33. The positive conductive strip 50 is electrically connected to the positive electrodes 41 of the soft packing secondary batteries 40.
The negative conductive strip 60 straddles the accommodation space 31 and includes two assembling ends 61 which are fixedly disposed on the two transverse side plates 33. The negative conductive strip 60 is electrically connected to the negative electrodes 42 of the soft packing secondary batteries 40.
The fuses 70 each include a first connecting end 71 and a second connecting end 72. The first connecting end 71 is connected to the positive conductive strip 50, and the second connecting end 72 is connected to the positive electrode 41 of the soft packing secondary battery 40, so that each soft packing secondary battery 40 is independently and directly connected to a corresponding fuse 70, which means that each soft packing secondary battery 40 has its own fuse 70, forming a battery assembly 10 which uses the positive conductive strip 50 and the negative conductive strip 60 as power output terminals.
The aforementioned is the summary of the positional and structural relationship of the respective components of the preferred embodiment in accordance with the present invention.
For a better understanding of the present invention, its operation and function, reference should be made to Figs. 3-5 again: The soft packing secondary batteries 40 are installed in the accommodation space 31 of the rack 30. After being connected to the respective fuses 70, the positive electrodes 41 of the soft packing secondary batteries 40 will be connected to the positive conductive strip 50, and the negative electrodes 42 of the soft packing batteries 40 are connected to the negative conductive strip 60, SO that the positive and the negative conductive strips 50, 60 can serve as the power output terminals of the battery assembly 100.
Referring to Figs. 3 and 4, the positive electrode 41 of each of the soft packing batteries 40 is connected to a corresponding fuse 70 in such a manner that each soft packing secondary battery 40 is independently and directly connected to the corresponding fuse 70, forming the battery assembly 100 using the positive and the negative conductive strips 50, 60 as the power output terminals thereof. When electric current exceeds a rated value due to failure of any one of the soft packing secondary batteries 40, the fuse 70 which is directly connected to the failed soft packing secondary battery 40 will be actuated to disconnect the failed soft packing secondary battery 40 from the positive conductive strip 50. As a result of this, the failed soft packing secondary battery 40 can be isolated from other intact soft packing secondary batteries 40, preventing the failed soft packing secondary battery from causing the failure of the whole battery assembly 100.
It is to be noted that, besides being connected to the positive electrodes 41 of the respective soft packing secondary batteries 40 as shown in Fig. 4, the fuses 70 can also be connected to the negative electrodes 42 of the respective soft packing secondary batteries 40 as shown in Fig. 6. In such a case, when the electric current exceeds the rated value, the fuses 70 can also realize the same function as described above.
Referring to Fig. 7 showing that four soft packing secondary batteries 40 are connected in parallel, the positive electrode 41 of each of the four soft packing secondary batteries 40 is connected to a corresponding fuse 70 first and then connected to the positive conductive strip 50 while the negative electrodes 42 are connected to the negative conductive strip 60, such that the four soft packing secondary battery 40 can be connected in parallel to form a battery assembly using the positive and the negative conductive strips 50, 60 as power output terminals.
Referring to Fig. 8 showing that four soft packing secondary batteries 40 are connected in series, the positive electrode 41 of each of the four soft packing secondary batteries 40 is connected to a corresponding fuse 70 first, and then the four soft packing secondary batteries 40 will be connected in series to form a serial battery assembly 43 having a positive output terminal 431 and a negative output terminal 432, and finally the positive output terminal 43 1 will be connected to the positive conductive strip 40 while the negative output terminal 432 is connected to the negative conductive strip 60, such that the four soft packing secondary batteries 40 are connected in series to form a battery assembly using the positive and the negative conductive strips 50, 60 as power output terminals Referring to Fig. 9 showing a serial-parallel connection between four soft packing secondary batteries 40, after the positive electrode 41 of each of the four soft packing secondary batteries 40 is connected to a corresponding fuse 70, two of the four soft packing secondary batteries 40 will be connected in series to form a first battery assembly 44 including a positive output terminal 441 and a negative output terminal 442, and the other two of the four soft packing secondary batteries 40 will be connected in series to form a second battery assembly 45 including a positive output terminal 45 1 and a negative output terminal 452, and finally, the positive output terminals 441, 45 1 of the first and the second battery assemblies 44, 45, will be connected to the positive conductive strip 50 while the negative output terminals 442, 452 of the first and the second battery assemblies 44, 45 are connected to the negative conductive strip 60, such that the four soft packing secondary batteries 40 can form a serial-parallel battery assembly using the positive and the negative conductive strips 50, 60 as power output terminals.
