BMW sticks to 50% EV target by 2030—not including hybrids, PHEVs

Green Car Reports
BMW still aims for about 50% global EV sales by the end of the decade, in line with a plan the automaker rolled out in 2021, but still isn’t ready to declare an end date for internal combustion. “By 2030, all-electric vehicles should account for about half of our deliveries,” CEO Oliver Zipse said Wednesday in a speech to shareholders. But the… Read more…

Battery energy density


Nick Flaherty looks at strategies to get more power out of battery cells, which brings thermal management challenges.
There are many ways to boost the energy density of an e-mobility platform’s powertrain. The materials in a battery cell can be improved to produce more energy, from silicon in the anode to new electrolytes. Solid state batteries under development, for example, can provide higher energy densities, stacking more cells closer together by addressing the materials and the packaging. Read more…

Thermal runaway prevention


Peter Donaldson speaks to experts who are working on cell design and chemistry to avoid thermal runaway
Protection from thermal runaway in an electric vehicle (EV) battery requires a holistic solution that affects every aspect of the pack’s design and operation. The consensus seems to be that protection options are limited to prevention and mitigation rather than stopping a runaway once it has started. Read more…
