PROBLEM TO BE SOLVED: To convert a braking energy into an electric energy even when an electric vehicle is decelerated by a brake pedal and recover the electric energy into a battery. SOLUTION: A shift gear which is interlocked with a brake pedal 2 and can shift down in proportion to a stepping distance is provided. An electric motor 4 which has a regenerative function as a generator is connected to the input side of the shift gear and a transmission shaft 5 which drives drive wheels is connected to the output side of the shift gear. |
