I have multiple ebikes, various are geared and voltaged differently.
Lately, I'm bored ... again!, the idea of multi-voltaging has perked my interest.
Dual voltage motor.
For example, running 22V 50Ah in town, (425w power - near 20 mph), would give me a very peppy eBike, while a quick battery rewire to 44V 25Ah, (850w power - 30++ mph assist), would give me great assist for high speed on the open road.
Battery "rewire" could be rigged into a single multi-contact switch or through multiple rigged electric contactors.
Would require a 22.2V - 44.4V compatible controller.
(I've started "componentising" my battery builds in 11.1V modules = 12.3V full charge)
(I am developing this as a method of best multi-tasking my electric motorcycle for city vs highway usage.
40mph at double the amps-acceleration - for in town
vs
80mph capability for highway use.)
More interesting is the idea of dual motors. (Brush motors required ... ?)
Running 44V through 2 motors "in series" would supply 22V to each motor for massive low speed torque.
Switching to "in parallel" would endow each motor with 44V, but with 1/2 the Amps.
Which would double the motor speed with a similar reduction in torque ... effectively giving a 2 gear electrical transmission. (Overdrive! ... ?)
48V SLA controllers match 44.4V Li-ion LVC nicely.
A multi-arm "shifting lever" could quickly switch between modes.
Re-routing power with electrically powered contactors would be very impressive.
