Abstract

The invention provides an all-electric vehicle with an EMT (electric-drive mechanical transmission). The all-electric vehicle comprises a motor, an EMT, an EMT gearshift, a vehicle control unit, a motor controller, a battery management system, a storage battery, a high-voltage distribution box, an on-board charger, a vehicular direct-current charge socket, a vehicular alternating-current charge socket, a shift knob, an accelerator pedal and a brake pedal. The problem that maximum speed fails to be along with maximum climbing performance when single gear is set is solved, and a vehicle transmission system is also improved. The all-electric vehicle is simple and convenient to operate, vehicle weight is decreased, and cost is lowered.

Description

Technical field [0001] The invention relates to a pure electric vehicle provided with an automatic transmission EMT. Background technique [0002] Since pure electric vehicles use electric motors instead of internal combustion engines in traditional fuel vehicles to drive vehicles, and the motors have better overall efficiency characteristics relative to engines, wide working speed range, and a wide working area with general efficiency greater than 80%. The significance of adjusting the working area Not as big as traditional internal combustion engine cars. However, for pure electric vehicles, if a single-gear transmission is adopted, the maximum speed and maximum gradeability cannot be taken into account. Summary of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a pure electric vehicle equipped with an automatic transmission EMT, including an EMT motor, an EMT transmission, an EMT shift mechanism, a v...
