Re: Battery size

I’d focus on what you want the students to learn and how many hours are they expected to put in on such a project. How many students will be involved? They will need to fill all the various roles that us DIYers do ourselves; project manager, parts and tools organizers, marketing (corporate donors of various components), project coordinator, schedule tracking, technical consultants, safety officer, CANbus programmer, etc.

Certain skills are learned using DC motors, slightly different skills with AC motors. Reused EV components from a junkyard are a third approach with skills developed that are most useful in the automotive EV world.

If your budget is tight with few corporate sponsors, go with a DC motor. What will be the disposition of the vehicle at the end of the project? One school near me raffles off the finished vehicle to pay for next year’s project. They usually do a classic vehicle restoration.
