Abstract

The invention provides a battery, and relates to the technical field of energy equipment, the battery comprises a shell and a plurality of battery units arranged in the shell, and each battery unit comprises a plurality of battery cell units; the plurality of battery units are sequentially connected in series, and the plurality of battery cell units in each battery unit are connected in parallel; or the plurality of battery units are connected in parallel, and the plurality of battery cell units in each battery unit are sequentially connected in series. According to the battery, the battery cell units can be connected in parallel to enable the battery to have high current, then a plurality of battery units are connected in series to enable the battery to have high voltage, and a single battery has high current and high power at the same time, so that the use requirement of the single battery can be met in some occasions with high-power requirements; the single battery can be directly used as a PACK structure, and a plurality of batteries are not required to be assembled into a battery module, so that the assembling process of the battery module is omitted, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of energy equipment, in particular to a battery. Background technique [0002] Existing lithium-ion batteries generally have a cylindrical structure or a square structure. Among them, the battery with a cylindrical structure is directly packed into a circular shell, and the battery with a square structure is packed with a winding core or a laminated cell. The battery structure is formed in the aluminum case. Existing batteries usually only have one circular winding core or one laminated battery cell, the voltage is the voltage of the single winding core or single laminated battery cell, and the power is low. In some occasions with high power demand, usually more A battery is used to form a battery module, and the manufacture of the module is cumbersome and requires a lot of materials. Contents of the invention [0003] The present invention aims to solve at least one aspect of the above technical problem...
