Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a rechargeable battery installation mechanism, and more particularly to a rechargeable battery installation mechanism capable of allowing a rechargeable battery to have more flexibility and convenient installation in application and reducing the cost of the rechargeable battery, extending the service life of the rechargeable battery and obtaining the optimum performance. 
         [0003]    2. Description of the Related Art 
         [0004]    A lithum cell has been demonstrated to play an excellent role of electronic device in many applications and is applied to portable consumer electronics such as mobile phones, personal digital assistants (PDA), hand-held power tools or laptop computers. Moreover, since environmental protection consciousness rises due to global warming, petrochemical energy power may be replaced with electric power to achieve energy saving and carbon reduction. The safety of a battery module cascaded by each lithum cell has also been greatly improved to satisfy a normal demand with respect to electric motor vehicles. 
         [0005]    Generally speaking, a battery has a constant output voltage. While using electric bicycles, electric motorcycles, golf buggies and hybrid power automobiles, its rated voltage and power demand are different. Positive and negative poles of several batteries are cascaded to form a battery set having output voltage of many times. Alternatively, positive poles of several batteries are connected, and negative poles of the batteries are also connected to form a parallel connection. The outputted electric capacity is larger than original, wherein when several batteries are cascaded or connected in parallel, nickel pieces are generally taken as a structure of electrically connecting each battery. 
         [0006]    A conventional multi-cascaded or multi-parallel connected high power battery set includes many batteries and a protection circuit board. Each battery is mutully soldered by utilizing nickel pieces so as to form a battery module that is cascaded or connected in parallel. The battery module then is soldered with the protection circuit board to assemble a high power battery set. However, the conventional assembly has the following defects:
       1. When each battery is mutually soldered and assembled, each battery must be soldered one by one to consume time and cost. If mistakes caused by testing the multi-cascaded or multi-parallel connected high power battery set occur, operators must dismount the circuit board from the battery module to really consume man power and greatly influence the efficiency.   2. The multi-cascaded or multi-parallel connected high power battery set is fixedly assembled. If a single or a portion of batteries is damaged, the whole set must be placed to incrase the utilization cost for users.   3. When the multi-cascaded or multi-parallel connected high power battery set is charged, voltage or electric capacity obtained by charged batteries is different due to each battery mutually cascaded or connected in parallel. Consequently, some batteries are not fully charged to reduce the utilization efficiency of the multi-cascaded or multi-parallel connected high power battery set.
