The guiding strips are connected to the polar heads and are disposed on the rack assembly, respectively. The rack assembly has a containing space for accommodating the lithium batteries, and each lithium battery is connected to the guiding strip by a guiding piece via one safety unit, such that the lithium batteries are connected in parallel, thus providing enough power with a small size. In addition, each safety unit can cut off the broken lithium battery separately, so as to avoid the immediate shut-off of the electric power.
Description
A BATTERY ASSEMBLY
BACKGROUND OF THE INVENTION
Field of the Invention The present invention relates to a battery assembly and, more particularly, to a battery assembly which utilizes a rack assembly and a plurality of guiding strips to enable a plurality of lithium batteries to be connected in parallel, and utilizes a plurality of safety units to cut off any broken lithium batteries to avoid the immediate shut-off of the electrical power.
Description of the Prior Art A battery assembly provides power to a mechanism, and the battery assembly must have a high voltage and a large current, such that the battery assembly can effectively drive the mechanism. And as the only energy to drive the mechanism, the use of a battery assembly is very important to the mechanism.
A plurality of batteries of a conventional battery assembly is installed in a box after the batteries are connected in parallel, and both ends of the circuit are connected to two polar heads by the parallel circuit. The polar heads provide a high voltage and a large current to the mechanism, and produce enough power. A
conventional battery assembly is usually used for equipment such as an electric vehicle, a mobile machine, and a remote control machine. However, the conventional battery assembly still has the following disadvantages:
Firstly, since the plurality of batteries in parallel connection is installed in one box, the parallel circuit is complex and, with the increase in the number of batteries, the number of the parallel circuits will be multiplied. As a result, the wires will occupy too much space, and this is the main reason why the electric power of the conventional battery assembly is difficult to improve.
Secondly, if any of the batteries is broken, this will not only produce excessive current to destroy the circuit equipment of the mechanism, but also will produce high heat to cause serious dangers.
To improve the above-mentioned problems, another battery assembly has been developed, this includes a fuse which is fixed to an end of the parallel circuit.
When a large current occurs, the fuse will cut off the electric power of the whole battery box immediately, so as to avoid producing high heat or high current, thus improving the security. However, such a battery assembly will cause other problems.
Since the fuse will cut off the electrical power of the whole battery box immediately when a large current is produced, the power will disappear immediately.
As a result, an electric vehicle may stop at the center of the road, a mobile machine may stop at a hazardous area, and a remote control machine may lose the return power. The only solution to the above-mentioned problem is to provide a spare battery system, but such a spare battery system will increase the cost and occupy too much space.
Therefore, an improved battery assembly is required to reduce the failures and save the installing space.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary object of the present invention is to provide a battery assembly which solves the conventional problem of security caused by the breaking of a single

The abovementioned is the structure and the location of each subassembly,
5 and the following is an illustration of the operation of the present invention.
Referring to Fig. 4, both sides of the rack assembly 10 are installed with three guiding strips 20, respectively, and the containing space 21 is formed between the three guiding strips 20 and the rack assembly 10 and is located at each side of the rack assembly 10. The lithium batteries 40 are orderly arranged in the containing spaces 21 between the guiding strips 20 and the rack assembly 10, respectively. The positive pole of each lithium battery 40 faces towards the mid guiding strip 20, and the negative pole of each lithium battery 40 faces towards the outer guiding strips 20.
Moreover, the lithium batteries 40 are connected to the guiding strips 20 by the guiding pieces 50. By such arrangements, the cooperation of the rack assembly with the guiding strips 20 enables the lithium batteries 40 to be connected in parallel.
In addition, the lithium batteries 40 are arranged in the small containing spaces 21, thus providing enough power from a small volume.
Hence, the independent separating type power battery assembly of the present invention is suited to applications requiring a high power source, and since its size is small, the present invention is particularly suited to equipment such as an electric vehicle, a motorcycle and an electric bicycle.

The lithium batteries 40 are orderly arranged in the containing spaces 21 between the guiding strips 20 and the rack assembly 10, respectively. The positive pole of each lithium battery 40 faces towards the mid guiding strip 20, and the negative pole of each lithium battery 40 faces towards the outer guiding strips 20.
Moreover, the lithium batteries 40 are connected to the guiding strips 20 by the guiding pieces 50. By such arrangements, the cooperation of the rack assembly with the guiding strips 20 enables the lithium batteries 40 to be connected in parallel.
In addition, the lithium batteries 40 are arranged in the small containing spaces 21, thus providing enough power from a small volume.
Hence, the independent separating type power battery assembly of the present invention is suited to applications requiring a high power source, and since its size is small, the present invention is particularly suited to equipment such as an electric vehicle, a motorcycle and an electric bicycle.
The key point is that one end of each guiding piece 50 is connected to the positive and negative poles of each lithium battery 40, and the other end of each guiding piece 50 is fixed in position by the associated screw 51 in the threaded hole 22 of each guiding strip 20. Each safety unit 60 is disposed on the associated guiding piece 50 and is located correspondingly to each lithium battery 40, and the safety unit 60 will cut off the guiding piece 50 immediately when a large current is
6 produced.
Thereby, each lithium battery 40 in parallel connection has its own safety unit 60. When any lithium battery 40 is broken or produces an abnormal current, the safety unit 60 will cut off the guiding piece 50 near the lithium battery 40 immediately, that is, the safety unit 60 will cut off the circuit of the lithium battery 40 effectively. At the same time, the other lithium batteries 40 in parallel connection will not be influenced, and the whole parallel electric energy can still produce enough power. Hence, the present invention can prevent the dangers produced by the immediate shut-off of the electric power or termination of the power.
Referring to Fig. 5, it is to be noted that a box 80 can be used to accommodate the whole rack assembly 10, with the polar heads 30 and 31 exposed out of the box 80. Such an arrangement not only facilitates the assembly of the present invention, but also can protect the lithium batteries 40 and the safety units 60 (such as water proof, dust proof, and crash proof). In addition, the provision of the screws 51 for locking the components facilitates the assembly and maintenance of the assembly of the present invention.
Referring to Fig. 6, the lithium batteries 40 can be connected in pairs in series and then parallelly connected to the guiding strips 20. Since the serially connected lithium batteries 40 can be connected by the guiding pieces 50, the batteries 40 can be connected in pairs in series and then parallelly connected. By such arrangements, each two serially connected 40 can share one safety unit 60, so as to reduce the number of the safety units 60.
Thereby, each lithium battery 40 in parallel connection has its own safety unit 60.

Referring to Fig. 6, the lithium batteries 40 can be connected in pairs in series and then parallelly connected to the guiding strips 20. Since the serially connected lithium batteries 40 can be connected by the guiding pieces 50, the batteries 40 can be connected in pairs in series and then parallelly connected. By such arrangements, each two serially connected 40 can share one safety unit 60, so as to reduce the number of the safety units 60.
