Panasonic's Vivi RX 10-S, which is due in Japan on August 20, works the same way many hybrid vehicle systems do: taking the energy from braking and harness it into recharging the battery. We all at some point of time in our life have used a bicycle, and we all pretty well know how its rear wheel mechanism is designed and configured with the pedals. Note however that we assumed over 500 feet of steep elevation loss. When he hooked the motor up to a conventional battery, he did find that it was quite usable, if a bit underpowered. This is because the motor is always engaged in an ebike with a regen system, so the motor is always turning even when coasting. In 2009, I wrote in these pages about my efforts to . So, from this analysis regenerative braking using rapid charge batteries like LiFePO4 could be a winning proposition. In 2009, I wrote in these pages about my efforts to .
