The first BMW EVs <\/a>powered by all-solid-state batteries are now on the road for testing. BMW used an i7 to test the \u201choly grail\u201d of EV battery tech, promising longer driving range at a lower cost.<\/p>\n

BMW tests first EVs with all-solid-state batteries<\/h2>\n

BMW hit a milestone on Monday after completing its first on-road tests using Solid Power\u2019s all-solid-state battery (ASSB) cells.<\/p>\n

Often called the \u201choly grail\u201d of EV battery technology, ASSBs promise significantly higher energy density than current batteries. Since they can pack higher energy density into a smaller space, all-solid-state batteries have the potential to boost driving range at a lower cost.<\/p>\n

The i7 test vehicle is based on BMW\u2019s current Gen 5 architecture, using new prismatic cells in modules. To integrate Solid Power\u2019s ASSB cells, BMW modified the platform using new module concepts.<\/p>\n

BMW and Solid Power have been working together since 2022 to advance the new EV battery tech. In December 2022, BMW revealed plans<\/a> to license Solid Power\u2019s tech for a new solid cell prototype line at its Cell Manufacturing Competence Center (CMCC) in Parsdorf.<\/p>\n

The German automaker will continue to test sulfide-based electrolytes in solid-state battery packs over the next few months.<\/p>\n

BMW follows Mercedes-Benz, which announced in February<\/a> it had put \u201cthe first car powered by a lithium-metal solid-state battery on the road\u201d through its partnership with US-based Factorial Energy. <\/p>\n

Mercedes used a modified EQS, fitted with solid-state batteries. With an expected 40% weight savings compared to current Li-ion batteries, Factorial aims to unlock over 600 miles of driving range.<\/p>\n

The milestone also comes after Martin Schuster, BMW Group\u2019s vice president of next-generation battery tech, told\u00a0<\/span>Autocar<\/a><\/em>\u00a0in February that solid-state batteries were still too expensive and that current lithium-ion batteries have \u201ca long way to go.\u201d<\/p>\n

Electrek\u2019s Take<\/h2>\n

German automakers are not the only ones advancing the promising new battery tech. Global battery leaders CATL and BYD are also expected to launch EVs with all-solid-state batteries<\/a> over the next few years.<\/p>\n

Sun Huajun, the CTO of BYD\u2019s battery business (Shenzhen BYD Lithium Battery Co), said earlier this year that the company expects its first EVs with all-solid-state batteries<\/a> to arrive in 2027. Production will be limited for the first two years, but by 2030, BYD expects ASSBs to enter the mass market.<\/p>\n

In the initial phase, BYD will use a sulfide-based solution in some of its higher-end models. Like BYD, CATL reportedly plans to begin production of all-solid-state EV batteries in 2027, but in small volumes.<\/p>\n

Several others, including Hyundai, Nissan, Stellantis, Toyota, and Honda<\/a>, are racing to develop the next generation of EV batteries.<\/p>\n

Which will be the first to launch all-solid-state EV batteries on a mass scale? CATL and BYD already lead the market by a wide margin, but others are quickly advancing with on-road testing. Let us know your thoughts in the comments.<\/p>\n
