AI Technical Summary
Technical Problem
Conventional battery modules have low space utilization due to the large width of the busbar, which limits the efficiency and capacity of battery packs in vehicles.
Method used
A battery module design where electrode leads are connected in a sequential overlapping manner, with a busbar coupled to only one of the overlapping leads, reducing the size of the busbar and minimizing overlap between leads, thereby improving space utilization and allowing for increased energy density.
Benefits of technology
This design reduces the size of the busbar, enhances space utilization, decreases manufacturing costs, and minimizes stress on electrode leads, allowing for more efficient packing and higher energy density without limiting the number of overlapping connections.
