January 3, 20206 yr I am keen to begin a new venture with an idea for a social enterprise business that is mainly bike based. The idea would require appliances to be powered from a bike but I don't want the bike to have to pitch at a market to become a "stall". I want 100% mobility, think of a coffee bike for example. I want ot be able to power a coffee machine and say small refrigerator without needing to hook up to mains. Crazy I know. My question being this; Is it possible to use a conversion kit on a trike style front loaded bike, have the power stored so that when needed can be used as a pedal assist and when static could help power the appliances? Thank you
January 3, 20206 yr Probably not from a bike battery. The bike/trike would be a heavy beast with equipment aboard, so power required to get/keep it moving would be a high draw on the battery, meaning range would be low. Any equipment would likely be 240v so would have to be powered via an inverter, introducing innefficiency power losses. Theoretically feasable but not really practical I fear.
January 3, 20206 yr I agree with Benjahmin, feasible but not practical. Think of how much power the vending system would need for a peak day. That could well be in the region of 20KWH. At the moment, 500WH batteries weigh about 3kgs, 20KWH is 40 times that, 120kgs battery. Then there is the material cost and SVA process to go through. 20KWH battery would cost you at least £8,000.
January 3, 20206 yr A better option might be to use a decent generator, such as one of the Honda EU series: https://www.energygeneratorsales.co.uk/honda-generator-sales/product-detail/honda-eu22i-22kw22kva-petrol-inverter-generator?gclid=CjwKCAiA6bvwBRBbEiwAUER6JRP3fl8qVflyhO1UxvEoDfGUAosON5CGG8zYUo3wOQn73D8l1lmIfhoCJ9oQAvD_BwE
January 3, 20206 yr What kind of coffee machine? How many kWh? How many hours will it be running? Once you have those numbers you will be able to calculate the size of your battery pack. You want a 48v motor and your batteries would be 2 x 24v used in series for the motor and in parallel for the 240v AC inverser. A 12v refrigerator is easy to run and doesn't require much power.
January 3, 20206 yr Better off using a large power wall/bank charged with solar power or deep cycle SLA batteries, non will come cheap.
January 4, 20206 yr Awww, sorry to pour cold gravy all over you Soupabike. It's a great idea but the laws of physics just get in the way. I'd look into the small generator idea (nasty co producing things), you'd need to check that any equipment used on it could stand up to the spikey output.
