Toshiba fast-recharge electric bike PDF Print E-mail

s9_Tailwind_M.jpgFor a while now I've been commenting that battery recharge time will be as important as capacity and power-to-weight ratio. This is particularly important for electric bikes and cars where a larger capacity battery also means more weight to carry around. Toshiba have just announced at CES that their batteries are being supplied to bike manufacturer Cannondale for its Schwinn Tailwind bike. Toshiba says this bike should be able to go 20-30 miles on a single charge, but more importantly recharge in 5 minutes, i.e. if you achieve 30mph and take a 5 minute break every hour your range is unlimited. For this recharge-ability to be achieved I hope that Cannondale design the battery for easy removal, so that for example it can be pulled out and recharged at a cafe. See Toshiba's press release I notice however on Schwinn's site that they only claim "charges in less than 30 minutes" which suggests they might not have incorporated a powerful enough charger to take advantage of the battery's capabilities. According to Envirofuel the bike can be charged with "commercial chargers" in 5 mins. Unfortunately at this point its not available in Australia as the motor is 250W which is above Australia's absurd 200W limit. See previous posts on the topic ...
