BMW is hard at work on its next generation of electric cars based on the Neue Klasse chassis, featuring round format battery cells.
BMW was fast out of the gate at the start of the EV revolution with its first battery-electric car, the i3. It featured lots of innovative thinking, especially its use of a mostly carbon fiber chassis, but it suffered from modest range at a time when public charging infrastructure was virtually non-existent.
It has been well over a decade since the i3 emerged and a lot has happened in the world of electric cars since then. BMW is now poised to bring its third generation electric cars to market using its all new Neue Klasse chassis. The first models are not scheduled to arrive until 2025, but the company is already trumpeting their wonders.
The batteries come in different chemical compositions to emphasize maximum power, extended range, slower degradation, or lower cost. The materials used include nickel, lithium, manganese, iron, silicon, and phosphate. It all adds up to 20% higher energy density, 30% better packaging efficiency, up to 30% more range, and up 30% quicker charging compared to the current batteries used. The company adds that manufacturing costs can be up to 50% less as well.
Why SSM instead of ASM or PSM ? Because according to BMW, only SSM warrants a stable peak performance, high energy density, excellent repeatability, and low noise emission together with a 97% efficiency rate.
