For batteries, I understand that you don’t want to go out on limb, at least initially. So cylindrical cells, probably NCM chemistry, 400v … all standard stuff, and the key thing you’re thinking about is integration. I get it, but the pushevs website has these things to think about for the future:
800-volt systems: more efficient, lighter motors vs. 400v
Silicon anodes: silicon/graphite is here now, but higher % silicon is coming
Cobalt-free batteries: switch from NCM to LFP, you’ll lose some energy density, but gain in safety and cost, simpler management, and no conflict minerals
CTP battery packs: Check out BYD’s blade batteries, works well with LFP chemistry
Solar roofs: Aptera is already there!
V2G and V2L: vehicle-to-whatever is coming
Aerodynamic improvements: Aptera is already there!
Wireless charging: well, someday
