Looking to build a set of hybrid karts for use by teenagers on go kart tracks. I'll use a standard track race kart chassis. Target performance is
- 4km of track driving (not racing yet, just driving) in full sun.
- average speed of 35kmh
The objective is for the kids to learn about electrical systems, not looking for race performance yet.
2 karts with 2000w motors, 500w of PV on car body, 576wh of lead acid (nominal)
2 karts with 3000w motors, 500w of PV on car body, 864wh of lead acid (nominal)
I have already built an 800w battery powered version, which does a solid 23kmh and runs for about 1km on a 252wh (nominal) pack (estimated - I haven't taken it that far).
This time I am putting solar panels on it. I don't have any experience with matching solar charge controllers, pv and lead acid. Any input welcome.
My main question is around the wiring diagram. I don't think I need to add diodes to protect the controllers as there is no regen in this system.
