Background technique

Generally, the traditional battery module structure is based on a plurality of batteries connected in series and parallel, and the terminals of the batteries are connected to each other to provide power. However, in the traditional structure (not shown in the figure), although multiple batteries are connected in series and parallel by welding, a separate accommodation space is required between the single battery and the single battery for the battery terminals to be welded to each other, so as to achieve multiple connections in series and parallel. A single battery can provide strong power, but because multiple batteries are connected in series and parallel, and additional space is required to place related components for protecting the battery, the battery module becomes bulky and cumbersome. Today's sophisticated electronic products all emphasize lightness, thinness and shortness. Huge battery modules are not only inconvenient for users to use, but too many batteries connected in series and parallel will make assembly and processing difficult due to the complicated design of series and parallel circuits. Therefore, the overall interconnection between batteries cannot achieve thinner, lighter and more efficient, which is the main disadvantage.
