Hi, this is more of a question about it being possible. I searched the forum before posting but didn't find the answer. I do a lot of eBike touring and in March I rode the southern tier 3166 miles across America. Last year I have about 5500 miles of touring. I have 2 52v 15AH batteries (lithium) which I use to help my 475 pound right, me and the fully loaded bike up hills and out run dogs.
So 1 of my batteries started to cut out / BMS safety prematurely when I would open up the throttle at around 49v. The battery has about 300 charge cycles and is now at the manufacture to get repaired. Is it possible to add just enough super capacitors to capture regenerative breaking and also supply that initial boost of power? Going down some of the larger hills and in cities coming to a fast stop because of cars or traffic light I use the region to slow me down. Going down some of these large grades I see my CA3 pulling over 500 watts of regen which I know is not good for batteries. Having some type of super capacitor as a buffer between the battery and controller might save my batteries.
Is there any information out there or ideas for this concept? I bike tour a lot and love it but blowing through a battery in 250 cycles / $1K battery is not fun. Thats about $4 a charge. I included a couple of photos of the trip including the 300 watt solar panel I use to charge in the middle of nowhere. : )
Thank you.
