How Many Volts to Run an Electric Car on a Generator?
If I can come up with something that produces electric power for a car motor, how many volts would I need to keep it running?
Hi, William -
You're asking how to eliminate the battery pack, right? The short answer is "I don't know." Anyway, I've only seen generators sold in terms of the number of kilowatts they produce, not volts. That will depend on the voltage of your EV system, I guess.
So here's the problem to solve if you don't want to use batteries:
Generators tend to run at a constant rate, not a variable rate. Electric motors that run electric cars need a lot of power available for acceleration and hill-climbing; this is why people keep the battery pack.
A small generator provides too little power for acceleration, a large generator that provides enough power for satisfying acceleration wastes a lot of electricity when the car's just cruising along at speed. What people usually do is go with a smaller, lighter generator that can charge a battery pack for range-extension (like the Chevy Volt, for instance).
Grid juice is way cheaper than generated-by-fuel electricity, so plugging in is popular.
Best of luck with your project!
