Compared with the traditional small cylindrical battery, the 4680 full-polar-lug large cylindrical battery developed by BIC power battery has strong advantages. Dr. Fan, head of battery research and development of BIC power battery, said: "The technology of large cylindrical battery can push the best balance point of energy density/cost and safety to a new position, and improve the size, space utilization and vehicle cruising range of single battery on the premise of ensuring the safety of the whole battery pack." At the same time, BIC power battery adopts large-size battery, which can reduce the number of batteries and corresponding structural parts in the whole package, thus improving the weight and energy density, simplifying BMS and reducing the overall industrial cost of battery packaging. From the vehicle level, the performance is improved, the cost is reduced, and the safety is further improved, which makes it possible for consumers to truly realize zero battery accidents, which also reduces the consumption concerns of potential consumers of electric vehicles to a certain extent and further expands the sales market of electric vehicles.
Bicycle power batteries have always attached importance to the automobile market. In the future, the full-pole-ear large cylindrical battery for high-end models of bicycle power battery will become the core product in the field of automobile application. Bicycle Power Battery Research Institute has begun to develop large-size cylindrical batteries and plan the mass production base of large-size cylindrical batteries. According to the actual research and development situation, BIC power battery full-lug 4086 battery is expected to be put into mass production in 2023, which is beneficial to the new energy automobile industry. ?
