A two-wheeled electric scooter principally powered by batteries which together provide more than 100 volts. The scooter carries an onboard recharging system to replenish the battery supply. Accordingly, the onboard recharging system is not called upon to provide the main power source for acceleration and other operating conditions. A recharging system is implemented either as a fuel cell which trickle charges the battery, or an internal combustion engine which recharges the battery through a mechanical charging unit such as an alternator or generator. Regenerative braking is provided so as to further conserve energy by back driving the motor to recharge the battery pack during braking. Connections are provided for an external power source such as an AC outlet to be plugged into the scooter so as to provide an alternate mechanism to recharge the batteries.

[ What is claimed is:] [14.]14. A two wheeled electric scooter comprising:a scooter frame including a compartment shaped and sized to accommodate a battery power supply having a voltage of at least 100 volts;an electric motor connected to said battery power supply via at least one switch, the electric motor configured to drive a rear wheel of the scooter;fuel cell configured to trickle charge the battery supply, the fuel cell running on either hydrogen or methanol, the fuel cell outputting a trickle charge of less than 2 amps;a first charging circuit configured to connect the fuel cell to the battery power supply so as to charge the battery power supply, the first charging circuit including a boost converter which receives a first voltage by the cell and outputs a second voltage to the battery power supply, the second voltage being greater than the first voltage,a fuel tank configured to hold the hydrogen or methanol fuel;a second charging circuit configured to connect the battery power to an external power source; anda motor controller circuit connected to the motor and configured to charge the battery power supply upon deceleration of the scooter.
