I'm considering upgrading my 72V 8.5kW (brushed DC) electric scooter with one of the higher power GoldenMotor. (15kW or even 20kW)
People usually use the GoldenMotor controllers with that. But I find them a little primitive. Or rather quite hard to find any details on features.
Since I'm right now considering using the Orion BMS I would really like a motor controller that plays well with that. (Intelligent power back-off when the BMS isn't happy and such)
Also, I really like to have CAN bus support.
Orion has good integration with Curtis controllers. But they are a bit chunky for a scooter and considerably more expensive than the Chinese controllers usually used with those motors.
Another consideration is that I really like to use a display unit like the http://ai-hmi.com/#products
IntelliGauge. Which has built in support for Orion and Curtis. But I'm pretty sure I could make it understand any kind of CAN message ifI had to.
What are you guys experience with high-ish powered electric motorbike controllers? Which are the good and the bad?
Especially with regards to more advanced features and CAN integration.
Like for example if I could add an interlock where the BMS can switch it off during charging without having to rely on heavy-duty contactors. In that case, I could design the whole thing with a single shut off contactor instead of one for the charger and one for the load
Most lower end BLDC just come on when there is power on the high power inputs.
I like fully built out complex solutions. And I'm not building some low power electric bicycle here. I like to have it proper.
