Description
Technical field:
The utility model relates to a kind of cell parallel battery pack, is specially adapted to the combination of cylindrical lithium ion battery parallel connection welding.
Background technology:
Along with the technology ripe and promotion of country to new forms of energy gradually of lithium ion battery, increasing auto vendor and energy storage producer start to develop electric automobile and are energy energy-storage system.Part electric automobile adopts the lithium ion battery of cylinder to be assembled into Li-ion batteries piles used for electric vehicle, because cylindrical lithium ion battery single battery capacity is little, and the energy that batteries of electric automobile group needs is high, therefore, little cylindrical lithium ion battery is needed to be assembled into jumbo lithium-ion battery monomer by mode in parallel, then jumbo battery cell is together in series again, boosted voltage, reaches the standard of Li-ion batteries piles used for electric vehicle.Common cylindrical lithium ion battery combination is the positive pole and the negative pole that are welded on battery by large nickel sheet, and form conduction and connect, whole nickel sheet does conductive strips, and internal resistance is comparatively large, and caloric value is also relatively large.
Summary of the invention:
It is simple that task of the present utility model is to provide a kind of battery pack structure, and welding is reliable, the cylindrical lithium ion battery batteries in parallel connection group that conductive capability is strong.
Task of the present utility model completes like this, cylindrical lithium ion battery batteries in parallel connection group, it is characterized in that: the plate face of positive pole cylinder manifold and another negative pole cylinder manifold is uniformly distributed and is welded with little copper nickel compound piece, the positive pole block of cylindrical lithium ion battery is welded and fixed by the little copper nickel compound piece on positive pole cylinder manifold, little copper nickel compound piece by another negative pole cylinder manifold is arranged on bottom negative pole box hat on described cylindrical lithium ion battery is welded and fixed, positive pole fixed mount and negative pole fixed mount are clamped in centre cylindrical lithium ion battery and fix formation entirety by screw and nut, form the top of the cylindrical lithium ion battery after an entirety and positive pole fixed support and the support bracket fastened centre of negative pole and be placed with pole fixed mount, the zone line of supporting bracket is divided into both positive and negative polarity Two Areas by " Z " font, Positive Poles in positive pole zone is crimped on positive pole cylinder manifold on pole fixed mount by screw, in negative regions, negative pole pole is crimped on negative pole cylinder manifold on pole fixed mount by screw, described pole fixed mount is coated with plastic cover by screw, positive pole fixed mount and negative pole fixed mount to be fixed.Two sides of described pole fixed mount are embedded with supporting bracket.Described plastic cover subscript is marked with the mark of positive pole and negative pole.
The utility model has following effect: the technical program has that conductive capability is strong, both positive and negative polarity pole at the top of battery pack, it is clear to identify, and is easy to be connected into the higher flat Li-ion batteries piles of electronic vapour.
