Problems solved by technology

In particular, electric vehicles generally require a large number of battery cells. If all the battery cells cannot be properly grouped in advance, it will be a laborious and dangerous operation to repair and replace individual battery cells one by one while the overall circuit still maintains a relatively high voltage and current. Mode, which is quite inconvenient for maintenance personnel, not only time-consuming, but also leads to high unnecessary risks

Abstract

The invention relates to a battery pack with multiple parallel cells and a power supply assembly with multiple battery packs connected in series. The battery pack mainly comprises a fixed frame device, the cells, top common electrodes, bottom common electrodes and at least one conductive column, wherein the fixed frame device comprises a plurality of storage grooves, the cells are arranged in the storage grooves, and at least one storage groove is used for installing the conductive column; the top common electrodes and the bottom common electrodes are respectively in conductive contact with the cells and two ends and locked on the upper side surface and the lower side surface of the fixed frame device, the top common electrodes form an electrode, and the bottom common electrodes are conductively connected with one another through the conductive column, are insulated from the top common electrodes and form another electrode. The power supply assembly with high electric capacity is formed by connecting the electrodes of the multiple battery packs in series / parallel.

Description

【Technical field】 [0001] The invention relates to a battery pack and a power supply assembly with multiple battery packs connected in series, in particular to a battery pack with multiple battery cores connected in parallel and a power supply assembly with multiple battery packs connected in series. 【Background technique】 [0002] Limited by the limited storage of oil and natural gas, which will cause a large amount of carbon emissions, the mainstream of modern technology has tended to reduce the use of polluting energy, trying to use natural sources such as solar energy, wind power, and water power to convert electrical energy into a pollution-free environment. clean energy. However, many vehicles currently use oil and natural gas as the driving energy. Therefore, how to properly use electricity to replace oil and natural gas to create safe and reliable electric vehicles has become a hot topic at present. [0003] In order to drive heavy-duty vehicles such as electric vehi...
