Hello all,
I have been looking around for the perfect controller and I am more and more interested about VESC project.
The 'only' problem is to switch it from skateboard power levels to something more adapted for ebike use.
I LOVE Marcos project and other members using IGBTs etc, but it's way overkill for an ebike and wayyyyyy beyond my skills (basically soldering through-hole components and not understanding much of the actual electronics).
I see two options here, I would need your opinion on both approaches:
1. First one (suggested by ElectricGod) briefly consists in buying a VESC, changing caps and mosfets, shunts, power the mcu, changing cables, and voila.
I suspect that changing mosfet for beefier ones requires a taking good care of specs. Gate resistor and surrounding components are supposed to match closely with the mosfet. Is it a big concern or am I splitting hairs ?
As anybody done this kind of mod already ?
2. Second option I see is to use Marcos design which decouples logic from powerstage and building a reasonnable powerstage for my needs.
I love how Lebowski gave instruction to build powerstage for his controller. I'd like to take inspiration from his post but I guess that marco's design assumes mosfets drivers should added there too. Is this correct ?
I think Marcos wants to focus on super-high powers only, but can someone think about an easy DIY powerstage for all ebike people craving for a VESC controller ?
I suspect that rising VESC specs to 100V (120V?) would be enough for most ebikes builds. Allow for 200A phase amps and you have a ton of people interested (just a guess though).
