Problems solved by technology

Using two jumpers complicates the operation for the user and also further increases the possibility of losing a jumper
Additionally, the configuration of the jumpers in the battery pack creates other potential risks
For example, external substances such as water can easily enter the internal structure of the battery pack and damage the cells or circuit boards of the battery pack

Abstract

A battery pack including a housing; and two or more battery cells located in the housing. The two or more battery cells interconnected by a configurable connector which is configured to enable electrical connections between the two or more battery cells. The configurable connector contains a plurality of first electrical terminals connected to the two or more battery cells, and a terminal holder adapted to be removably connected to the plurality of the first electrical terminals. The terminal holder is adapted to be installed to the housing in a first orientation at which the two or more battery cells are electrically connected, or in a second orientation at which the two or more battery cells are not electrically connected. The terminal holder contains a plurality of second electrical terminals. One of the plurality of the second electrical terminals always engages with a same one of the plurality of the first electrical terminals, when the terminal holder is installed to the housing in the first orientation or the second orientation. The single terminal holder can be installed to battery pack in different orientations for enabling / disabling the internal circuit of the battery pack, and can be locked by a latch mechanism, which reduces the chance that the terminal holder is accidentally lost during usage.

Description

technical field [0001] The invention relates to an electric energy storage device, in particular to a battery pack comprising a plurality of battery cells. Background technique [0002] Battery packs are commonly used in portable electrical equipment and tools, allowing the equipment and tools to be used in environments without a fixed power source. For example, power tool manufacturers often produce universal power packs that are compatible with different types of cordless power tools (eg, drills, hammers, screwdrivers, angle grinders, etc.). Battery packs typically consist of multiple battery cells housed in a one-piece housing that allows the user to easily install and remove the entire battery into or from a power tool via a latch mechanism configured on the battery pack housing . [0003] However, conventional battery packs are typically manufactured in a factory ready-to-use condition, meaning that the battery pack is fully assembled and ready to use before leaving t...
