Abstract
The invention belongs to the technical field of a battery product, and particularly relates to a lithium battery energy storage module and a lithium battery energy storage module group. The lithium battery energy storage module comprises a battery cell, a battery cell support and a busbar, wherein a tab of the battery cell is fixedly arranged on a tab fixed part of the battery cell support, the busbar comprises a first busbar plate, a second busbar plate and a connection plate, the first busbar plate and the second busbar plate are welded with the tab of the battery cell arranged on the battery cell support, and the connection plate is fixedly connected with the tab fixed part. The special busbar is arranged and is used for connecting in series and in parallel each battery cell on the battery cell support, the electrical contact area of the battery cell during busbar can be reasonably set by controlling sizes of the first convergence plate and the second convergence plate, so that theeffective and electrical contact are among the battery cells is ensured, energy loss caused by overheat of the lithium battery energy storage module is prevented, favorable thermal control of the energy storage module is facilitated, and meanwhile, the energy storage application efficiency of the energy storage module is improved.
Description
technical field [0001] The invention belongs to the technical field of battery products, and in particular relates to a lithium battery energy storage module and a lithium battery energy storage module. Background technique [0002] Since its inception in 1990, lithium-ion batteries have been sought after by 3C digital, power tools and other industries due to their high energy density, high voltage, environmental protection, long life and fast charging, especially for their contribution to the new energy vehicle industry. particularly prominent. [0003] As we all know, the energy storage of lithium battery cells is limited, and they often cannot meet the power supply requirements of electric energy products when used alone. By connecting several to hundreds of lithium battery cells in series and parallel to form one or more battery modules, so, The electric energy of multiple lithium batteries can be integrated and output together, which can greatly improve the energy stor...
