A while back, I had gotten a PowerWheels Jeep, but it didn't have a battery or charger. And it always seems that these toy cars end up getting left outside anyways, AND it's a little bit of a pain to pull out the battery to recharge.
Since I already built a full-size electric car AND I am interested in renewable energy, this was the perfect chance for me to build my own low-voltage SOLAR-POWERED ELECTRIC CAR!
The project integrates the PowerWheels with a battery, PV Solar Panels on a custom rack, and a solar charge controller, to design a child's solar-electric car.
Let's get started!
Step 1: Tools and Materials
Here's the Materials:
