I have been interested in using VESC for low cost e-bike projects for quite some time, but the 60V limit has always been a major problem. I see that TI now has the new 100V DRV8350 shipping and it seems rather similar to the DRV8301 VESC uses. The DRV8350 comes in 40-Pin WQFN package rather than the 8301's 56-Pin HTSSOP package so it's not quite a drop in replacement, but it seems close. Price wise, the DRV8350 and DRV8301 are nearly the same on digikey.
So a higher voltage VESC would need a different layout for the driver ship, higher voltage capacitors and MOSFETs. What else?
Has anyone already started on this? I suspect the market for VESC based e-bike products would be similar or larger than skateboards.
