The invention discloses a voice warning system of an electric automobile. The voice warning system of the electric automobile comprises a sound factor fuzzy analysis device, a digital-to-analogue conversion device, a signal amplification device and a voice warning device. The sound factor fuzzy analysis device is used for acquiring a first fuzzy variable according to a vehicle speed signal and a second fuzzy variable according to an accelerator pedal opening signal, acquiring a third fuzzy variable according to the first fuzzy variable, the second fuzzy variable and a preset fuzzy control rule, and calling a first subordinating degree function corresponding to the first fuzzy variable, a second subordinating degree function corresponding to the second fuzzy variable and a third subordinating degree function corresponding to the third fuzzy variable to output sound factors. The digital-to-analogue conversion device is used for converting digital signals corresponding to the sound factors to be analogue signals. The signal amplification device is used for amplifying the analogue signals. The voice warning device is used for emitting voice warning information according to the amplified analogue signals. The voice warning system can correctly output voice warnings and guarantee the safety of pedestrians. The invention further discloses a voice warning method of the electric automobile and the electric automobile.
