Ive just had first trial run of my new invention, not named yet, (suggestions welcome??)
Anyway working fab in this sunny weather.
Set up is 16 (2.7v 3000F) Ultracaps, each with own 400miliamp 2.5v solar panel (thats one 10cm x 12cm on each capacitor)
250w 24v motor on my bike and 48v controller (with low voltage cut off removed). Throtlle only used at half when caps are full.
Sits on bike charges up, and you can use it for about 7or 8 minutes continuous, seems to take about an hour to charge from flat tho, so I intend to save it for hills etc.
Worked better than I expected. I only use the throttle half way when the caps are full up, so the motors not getting more than 30volts ish, and then full throttle when caps are low.
Needed it like that, to have a more powerful voltage and controller and then limit it by the throttle because of the way capactitors decline their volts when discharging, its not a flat discharge like batteries
Cost of this to make the solar panel units on capacitors was about £400 so not cheep. But no balancing required, or any other issues.
Anybody reckon this is worth 'taking to market'? I wouldnt know where to start - also I need that name lol
