BMW guarantees 30% enhancements in vary, charging velocity with next-gen battery


BMW on Friday offered the primary particulars on its new sixth-generation battery design. Due across the center of the last decade, the sixth-gen battery guarantees vital efficiency enhancements over the present fifth-generation design used within the automaker’s newest electrical automobiles, just like the 2022 BMW iX and 2022 BMW i4.

Based on the automaker, the brand new design interprets to a 20% enchancment within the cell’s volumetric power density. The automaker additionally estimates vary will likely be improved by 30% over a fifth-generation battery of comparable measurement and weight.

One other key benefit of the brand new battery is a change to an 800-volt electrical structure, one thing increasingly automakers are adopting because it allows DC quick charging at excessive charges. BMW hasn’t talked about a selected time determine however mentioned charging a battery from 10%-80% needs to be about 30% faster than it’s as we speak.

Growth of batteries takes place at BMW’s Battery Cell Competence Middle positioned in Munich, Germany. BMW may also be liable for manufacturing of the batteries, which will likely be dealt with by six crops every with an annual capability of as much as 20 gwh. The six crops will likely be divided equally amongst China, Europe, and North America, and can use each new and recycled supplies for the batteries. This final issue, together with the brand new cell design, means the price of producing the battery may very well be diminished by as much as 50%, in comparison with the fifth-generation battery, BMW mentioned.
