Battery cartridge {BATTERY CARTRIDGE}

The present invention relates to a battery cartridge, and more particularly, to allow the battery cartridges having a plurality of battery cells built therein to be variably combined for various purposes, as well as storing the produced electricity in a grid energy storage. Cartridges for auxiliary couplings (e.g., battery management system (BMS) circuits or battery serials) that are widely used in energy storage systems (ESS), which are used to supply energy when energy is needed most and to increase energy efficiency. And it relates to a battery cartridge invented so that the parallel connection bus bar (Busbar cartridge, etc.) and the battery cartridges can be combined easily and simply and firmly in various combinations.

In general, a secondary battery such as a lithium ion battery means a battery that can be charged and discharged, unlike a primary battery that cannot be charged, and is widely used in various fields and devices such as an electronic device or an electric vehicle such as a mobile phone, a notebook computer, a camcorder, and the like. .

Currently commercialized secondary batteries include nickel cadmium batteries, nickel hydride batteries, nickel zinc batteries, lithium secondary batteries and the like, and metal air batteries, all-solid-state batteries, sodium-based batteries, magnesium batteries, and the like have increased interest and development as next-generation batteries. have.

Among these secondary batteries, lithium secondary batteries have been in the spotlight for advantages such as free charging and discharging, very low self-discharge rate, and high energy density compared to nickel-based secondary batteries.

In this case, one or more secondary batteries may be included in the battery cell, and the plurality of secondary batteries may be configured in various forms including one stacked in one direction, for example, an up and down direction.
