Described terminal box 6 has 3, and the quantity of general battery strings and terminal box can change according to the design needs.Described battery strings has arranged side by side 6 groups, and the first Battery pack string that is positioned at the substrate left side utilizes the short busbar 2 of a vertical bar shape to draw respectively with the leading-out terminal that is positioned at the 6th Battery pack string on substrate right side; Be positioned at the second Battery pack string at substrate middle part and the leading-out terminal of the 3rd Battery pack string and utilize the long busbar 3 of a vertical bar shape to draw, the 4th Battery pack string and the 5th Battery pack string utilize the long busbar 3 of another root vertical bar shape to draw.Between substrate and battery sheet 1, eva film is arranged, eva film, insulating protection material are arranged on battery sheet 1 successively.
The utility model has the advantages that: because used lead-in wire and busbar all be linearity, draw the busbar of assembly electric current and external cable line for the shortest, and reduced solder joint, when operating, also need not bend.Therefore, the kind and the quantity of material 1, have been reduced; 2, reduce the complexity of technology, enhance productivity.3, reduce hidden danger of quality.4, reduce line loss, improve the energy output of assembly and even system.
Description of drawings
The head front schematic view of battery component during Fig. 1.
Fig. 2 is the afterbody reverse side schematic diagram of battery component.
Embodiment
Among the figure: 1, battery sheet, 2, short busbar, 3, long busbar, 4, the gap, 5, frame, 6, terminal box, 7, cable, 8, interconnector.
As shown in the figure: installation base plate on frame 5, some Battery pack strings are arranged in the front of substrate, the exit that battery strings is arranged at the head of substrate, described battery strings is made up of some battery sheets 1, between adjacent two battery sheets 1 gapped 4,1 of adjacent two battery sheet in a Battery pack string utilize interconnector 8 to be electrically connected mutually, the leading-out terminal of every Battery pack string utilizes short busbar 2 or long busbar 3 to draw respectively, and described short busbar 2 or long busbar 3 are electrically connected mutually with the terminal box 6 that is installed on the substrate tail end back side.Be that described short busbar 2 or long busbar 3 are electrically connected with the interconnector 8 of the leading-out terminal of corresponding battery strings respectively.
Described terminal box 6 has 3.Described battery strings has arranged side by side 6 groups, and the first Battery pack string that is positioned at the substrate left side utilizes the busbar 2 of a vertical bar shape to draw respectively with the leading-out terminal that is positioned at the 6th Battery pack string on substrate right side; Be positioned at the second Battery pack string at substrate middle part and the leading-out terminal of the 3rd Battery pack string and utilize the busbar 3 of a vertical bar shape to draw, the 4th Battery pack string and the 5th Battery pack string utilize the busbar 3 of another root vertical bar shape to draw.Between substrate and battery sheet 1, eva film is arranged, eva film, insulating protection material are arranged on battery sheet 1 successively.Described substrate mostly is glass greatly.
Wherein the short busbar 2 of the first Battery pack string and a terminal box 6 interconnect, the long busbar of shared one of the shared long busbar 3 of second, third Battery pack string and the 4th, the 5th Battery pack string 3 common be positioned in the middle of a terminal box 6 be connected, short busbar 2 and last terminal box 6 of the 6th Battery pack string interconnect.
The leading-out terminal of each battery strings of assembly is disperseed to draw, and on adjacent two leading-out terminals, a terminal box 6 is set, a bypass diode is set in terminal box 6.
