Like most other automakers, BMW is working on future battery technologies. By the end of the current decade, the technique of “solid” batteries and other solutions with enormous potential should finally be mastered. In the meantime, current liquid-cooled battery technology will continue to improve. This is the case within the brand with the propeller with the arrival of a new evolution of batteries which will be inaugurated in 2025 in an unprecedented electrical architecture, the “New Klasse”. While the current batteries used by BMW have prismatic cells, future ones will prefer cylindrical cells with a diameter of 46 mm. They will contain more nickel and less cobalt on the cathode, with more silicone on the other side. These modifications of the chemistry will make it possible to gain approximately 20% in energy density.
The big advantage? A gain estimated at around 30% in terms of autonomy but also charging speed. This solution will also reduce production costs and improve the ecological balance of batteries: the carbon footprint would be reduced by 60% in the battery production scheme and it will also use a large proportion of recycled cobalt. BMW plans to build no less than six giant factories around the world to produce these new cylindrical cell batteries. Some of these factories will be located in Europe and the United States, but the partner will be Chinese (CATL and EVE Energy).
50% of electric BMWs in 2030
BMW is one of the automakers hoping to keep the combustion engine as long as possible, but according to its forecasts, around 50% of the brand’s cars sold worldwide in 2030 will be electric. Currently, there are four electric models in the range: the compact i3 still not sent to retirement, the iX3, the i4 and the large SUV iX. Without forgetting the electric Mini.
