Citicar - from 48v to 64v
I recently upgraded the voltage in the Citicar from 48v (stock) to 64 volts. It is interesting the difference a few volts make!
Acceleration has improved greatly. It used to accelerate OK up to about 25, but run out of steam at about 25 MPH, accelerating rather slowly to the max speed of around 34 MPH.
The Citicar now accelerates well (better than many IC vehicles) to just over 35 MPH, with a top speed (unweakened) of around 42 MPH. A big goal was to get the Citicar to accelerate to, and maintain some speed above 40 MPH. At 64v, mission accomplished - thus the change for the Avatar title!
It goes a bit faster still with field weakening. It will do at least 45, but I limit the Citicar to 45MPH in order to not overspeed the motor. At 45, it is doing about 5,000 RPM.
Makes me wonder why I didn't go to a higher voltage a few years ago!
