According to Autocar, BMW is aiming to fix this issue with a breakthrough in battery technology in 2026, by which time it plans to have solid-state batteries ready for production in its models.
The batteries will use lithium ion technology but swap liquid electrolytes for solid ones, with initial targets being for a 15-20 percent increase in capacity.
A second, but equally important benefit of the new battery technology is a reduction in weight and in the amount of safety protection needed due to the reduced fire risk.
The report also says that the the batteries are currently in development but 10 years away from production, with long-term durability testing cited as a key reason for the delay.
BMW is currently building their battery packs in house, with cells being provided by various companies.
