为提升电动车的续航功能,宝马的工程师研发了一款高效能电池,可将i3原有电池的能量密度增加50%,令到每次充电后的综合续航力达到183公里。电池单元可独立更换宝马i3原有的电池为60Ah,而新电池则提升至94Ah。新电池是由8个电池单元组成,而每个单元设有12枚独立电芯。工程师透过优化电池内部结构及采用新的活性物料和增加电解液,令到新电池在没有改变体积下也能显着提升功能。i3 94Ah所用的锂离子电池
To enhance the life of an electric car, BMW engineers developed a high-performance battery that increases the energy density of the original i3 battery by 50% to a total of 183 kilometers per charge. The battery unit can be replaced independently BMW i3 original battery is 60Ah, while the new battery is raised to 94Ah. The new battery is composed of eight battery cells, each unit has 12 separate batteries. By optimizing the internal structure of the battery and using new active materials and adding electrolyte, engineers can significantly improve the functionality of the new battery without changing its volume. i3 94Ah lithium-ion battery used
