A kind of ultracapacitor module

Technical field

The utility model relates to ultracapacitor, relates in particular to a kind of mutual-inserting type ultracapacitor module.

Background technology

Super capacitor is a kind of novel energy-storing device between traditional capacitance and secondary cell, has the high power characteristic of traditional capacitance and the high-energy characteristic of battery concurrently.Characteristics such as the high-specific-power of super capacitor, high current charge-discharge ability, long-life, ultralow temperature performance, high reliability, environmental protection have special advantages in fields such as industrial electronic, communications and transportation, the renewable energy resources, military affairs as power power-supply or accumulation power supply.But when ultracapacitor is connected use, have the electric voltage equalization problem between monomer, simple series connection can cause one or several super capacitor monomer overvoltage, thereby damages these super capacitor monomers, and overall performance is affected even lost efficacy.

Existing super capacitor module; The mounting means of its super capacitor monomer is shown in Figure 1A, 1B; Super capacitor monomer 1 is all closely arranged and is welded in PCB (Printed Circuit Board; Printed circuit board (PCB)) on the plate 2, row has expired the welding foot and the both positive and negative polarity connecting circuit of super capacitor monomer 1 at the back side of pcb board 2, has not had vacant space arrangement balancing circuitry.The product that has has directly been cancelled balancing circuitry, brings hidden danger for super capacitor module stability.The product that has is one group with several super capacitor monomers 1; Receive a shared balancing circuitry on the other pcb board with the connecting line mode; Though improvement is arranged like this; But because of a plurality of super capacitor monomer 1 shared same balancing circuitrys of need, thus still there is the unbalanced hidden danger of monomer voltage, and increased the complexity of product and processing technology thereof.

Summary of the invention

The utility model is to the drawback of prior art, not increasing basically under the condition that the super capacitor monomer takes up room, provides a kind of at the other super capacitor module that voltage balancing circuit is all arranged of each super capacitor monomer.

This super capacitor module comprises first, second pcb board and welds a plurality of super capacitor monomers on said first, second pcb board that wherein, said a plurality of super capacitor monomers are divided into two groups, are welded on said first, second pcb board with certain interval respectively; The face that said first, second pcb board is welded with the super capacitor monomer is plugged on together relatively, and said a plurality of super capacitor monomers stagger each other; Interval region on said first, second pcb board is provided with voltage balancing circuit respectively; Also comprise the fixed mount that is used for fixing said first, second pcb board.

Preferably, said certain interval is meant the diameter that is a bit larger tham said super capacitor monomer.

Preferred again, the said super capacitor monomer that a said PCB goes up welding is arranged in N row, and the said super capacitor monomer that said the 2nd PCB goes up welding is arranged in M row; After said first, second pcb board was plugged on together, said N row and M row alternately arranged successively; Wherein, N >=2, M >=2.

Further preferred, said fixed mount has two, is separately positioned on the end of the corresponding side of said first, second pcb board.

Through a plurality of super capacitor monomers are divided into two groups, weld respectively on first, second pcb board, be plugged on relatively together then; The utility model is not increasing under the condition of ultracapacitor module volume basically; The area of pcb board is multiplied, thereby can voltage balancing circuit be set, solved product stability problems each super capacitor monomer; And simple in structure, make things convenient for processing and manufacturing.

Embodiment

Below in conjunction with embodiment and contrast accompanying drawing the utility model is done further detailed explanation.

Shown in Fig. 2 A, 2B, be respectively super capacitor monomer in the utility model ultracapacitor module the mounting means schematic side view and along perpendicular to the super capacitor one-body shaft to cross-sectional schematic.

This ultracapacitor module comprises: first, second pcb board 2 and be welded on a plurality of super capacitor monomers 1 on said first, second pcb board 2; Wherein, Said a plurality of super capacitor monomer 1 is divided into two groups, and the interval with the diameter that is a bit larger tham said super capacitor monomer 1 is welded on said first, second pcb board 2 respectively; The face that said first, second pcb board 2 is welded with super capacitor monomer 1 is plugged on together relatively, and said a plurality of super capacitor monomers 1 stagger each other; Interval region 4 on said first, second pcb board 1 is provided with voltage balancing circuit for respectively each super capacitor monomer 1.This ultracapacitor module also comprises 2 fixed mounts 3 that are used for fixing said first, second pcb board 2, conveniently is arranged on the left and right end portions of first, second pcb board 2, is used for first, second pcb board 2 is fixed together.
