I stumbled across this while looking for some info on upcoming power electronics that might be involved in adoption of 800v packs.

The really interesting stuff is in the "Subprogram Annual Reports"

Annual Progress Reports | Department of Energy

Loads and loads of interesting information on the ongoing (and completed) research.

Everything from assessments of different motor technologies, where the research labs are up to with varying battery chemistry, what research is on going to address cost issues in key elements of EV's (from power electronics to permanent magnet options to battery production), etc. etc.

It's a huge amount of bedtime reading!!

I'm incapable of understanding more than a small fraction of one percent of the executive summary of the one document I looked at. However, what I took from it was that:

a) They're confident that the current Li-ion batteries are going to last 10-15 years and 1000-5000 deep discharge cycles, which is good news on life but a warning not to deep discharge if you can help it?
b) They're looking at new battery technologies with an aim of 400kw charging and an XFC (extra fast charging) target of a 15 minute charge - so implicitly a 100kwh battery.

The material's all American, for those interested,.
