BMW has commenced testing its i7 EV equipped with a large-format solid-state battery, marking a significant milestone as the first prototype on public roads. Despite this advancement, BMW's Vice President of Battery Cell, Martin Schuster, suggests that solid-state technology will not be crucial for their electric vehicles until at least the mid-2030s. The i7 uses prismatic cells similar to their existing Gen5 batteries, highlighting that this vehicle serves primarily as a testbed rather than a production model.
This solid-state i7 utilizes the same type of prismatic cells as the manufacturer's Gen5, which are used in its current electric vehicles.
With the advancements brought by its Gen6 batteries, BMW doesn't think it will need solid-state in its EVs this decade.
The fact that it has cell casings from the current generation of production BMW EV batteries indicates that this vehicle is purely a testbed for the technology.
Our BMW i7 ASSB test vehicle on the road is a perfect example of the BMW Group's technology-open mindset.
