Charging Question
Hello ecomodders!
I'm new and was wondering if I could get some advice on a project. Project details: Series Hybrid Tour Boat- turbo r-12x jetski engine warp9 motor 12-14 48V50A Lifepo4 batteries The requirements for this boat is to run on the electric motor for the 4 hour downstream tour, and then use the gas engine to get back upstream in an hour. It has to make 2 consecutive tours. The plan is to charge the batteries off the engine's alternator. Perhaps with a voltage booster in between the alternator and batteries. This is where I need advice. 1) Does this sound remotely feasible? 2) I'm a bit hazy on my recharging fundamentals... is it correct that Voltage input needs to be higher than that of the battery pack it's charging, and Amperage is proportional to charging time up to a certain max amperage(3C)? 3) Anyone know where to find high quality, high output alternators? Sorry for the list of questions, I've tried searching and haven't found the answers yet. |
Lemme be useful first.
1) Yep 2) Yep 3) Dunno If the purpose of this hybridizing is to save on gas, you can't use the engine to recharge the battery. You'll use even more gas this way. |
The purpose is focused more on a quieter tour experience. Also on proof of concept. Anyone ever heard of an alternator producing ~30kW?

30kw out of an alternator? sure, but they tend to be on top of wind turbine towers and weigh hundreds of pounds, you are going to need an engine that is putting out around 45-50hp to turn that alternator as well.
