Abstract
The invention provides a method for connecting batteries in battery packs in series and in parallel for the society. A conducting plate is arranged between every two sets of serial battery packs, and elastic tongues of the same number as parallel connected batteries are arranged on the conducting plate, wherein the upper surface of each elastic tongue is contacted with the negative pole of a battery, and the lower surface can be contacted with the positive pole of another battery connected in series with the battery; and at the same time of connecting the batteries at the upper side and the batteries at the lower side in series, the conducting plate also connects all the batteries in the layer of the conducting plate in parallel. The invention thoroughly changes a spot welding connecting mode of a conventional battery pack and fundamentally solves stubborn damage problems caused by spot welding. The conducting plate of each layer can simultaneously finish the serial connection and the parallel connection of a plurality of batteries and improve the working efficiency of combining the battery packs. The method has no damages to the batteries when combining the batteries or splitting the batteries and is quite convenient for the maintenance of the battery packs and the replacement of the batteries.
Description
Technical field:
The present invention relates to series connection and method in parallel that a kind of cell is assembled into battery pack, be particularly useful for the series connection and the parallel-connection structure of the large-sized battery pack of many cell series connection and parallel connection.
Background technology:
The series connection of battery and method in parallel all are at every anode and negative pole spot welding conducting strip in the current battery group, by these conducting strips battery are connected and are connected in parallel.Find in the production process that the spot welding conducting strip is easy to damage battery, in addition, the battery that links together by the spot welding conducting strip is difficult to its decomposition is changed and keeped in repair.
Summary of the invention:
The objective of the invention is: series connection and parallel-connection structure that a kind of battery is provided, it does not need spot welding or other welding manner, can easily several batteries be connected and are connected in parallel, also can easily battery be split, no matter be assembled battery or fractionation battery, battery is had no damage.
Technical scheme of the present invention is: the present invention has a conductive plate in the centre of two groups of series batteries, the elastic tongue piece that equates with number of battery cells in parallel is arranged on the conductive plate, each can contact the negative pole of battery above the elastic tongue piece, can contact the positive pole of another series connection with it battery below, when conductive plate is cascaded top battery and following battery, all batteries that also will this layer are connected in parallel, so just constituted one 2 string many and battery pack.Make to use the same method, can make up any battery series connection and any battery parallel battery as required.
The further technical scheme of the present invention is: a connecting plate that causes with insulating material is arranged in the middle of two groups of series connected battery groups, the external diameter of connecting plate battery on corresponding and below the position of external diameter of battery the dimple of self-contained battery is all arranged, the two ends up and down of each battery are fixed in the middle of the dimple of connecting plate, and the positive electrode of battery and negative electrode and elastic tongue piece keep excellent contact.
In the technique scheme, the elastic tongue piece of described conductive plate can be the waveform tongue piece, and it can contact the negative pole of an anode and another series connection with it battery simultaneously; In the middle of elastic tongue piece can also be processed into is the positive pole that the waveform tongue piece is used to contact a battery, and several elastic claws are arranged on every side, and elastic claw can clamp the external diameter of another series connection with it battery cathode.
Advantage of the present invention is: invention has thoroughly changed conventional batteries spot welding connected mode, fundamentally solved the persistent ailment that causes battery to damage because of spot welding, each layer conductive plate not only is cascaded top and following battery, simultaneously all batteries that also will this layer are connected in parallel, improve the operating efficiency of assembled battery group, no matter be assembled battery or fractionation battery, battery is had no damage, the maintenance of very convenient battery pack and battery altering.
