I've built a mini camper. Although I have some limited knowledge of renewable energy and electric motorized bike parts I have been finding new ways to confuse myself. I currently have a mid drive PAS bicycle running a 48v 20ah lipo4 pack, this gets me about 80miles. I also have a hub motor mounted to a large trailer it has two, 36v 15ah lipo4 packs in series 72v maxout, this is basically an aux throttle power for hills or just a boost. I believe I have ample room to install two 120watt semi flexible panels and a 400 watt wind turbine on said trailer. From here I'm very unsure about exactly how to replenish my battery bank without carrying any additional battery storage. My thought is I could run the two 36v packs in parallel as my system battery bank. This might work since the trailer hub motor is only drawing load intermittently. I have read you can charge a system like this using 3 phase parameters and still safely apply load. This method would, I think, allow me to charge the other 48v system via the inverter after I stop for the day. Other components I think I need: hybrid MPPT controller, power inverter, load dump With so many options on the market I'm hoping some guidance will allow me to come up with a viable systems. I'm planning to travel the country with this set up in the coming year. Obviously that makes overall weight a major focus. Thanks for reading.
