Problems solved by technology

[0007] Strategy 1 is suitable for situations where there are motors with higher specifications. If due to certain conditions, motors with higher specifications cannot be obtained or require a huge cost, then strategy 1 cannot be implemented.
Strategy 2 increases the complexity of the system. At the current level of multi-speed automatic transmission, there are great technical risks

Abstract

The invention discloses a power output system of an electric vehicle, a method and the electric vehicle; the system comprises a front axle, a rear axle, a front axle speed reducer, which is connectedwith the front axle; a rear axle speed reducer, which is connected with the rear axle; a motor clutch, which is connected with the rear axle speed reducer; a first motor, which is connected with the front axle speed reducer; a second motor, which is connected to the motor clutch; wherein the output power of the first motor is greater than that of the second motor. According to the embodiment of the invention, different motors and clutches are arranged on the front axle and the rear axle, so that the high-speed and low-speed running requirements of the vehicle are respectively met, and the influence of the lack of a high-power motor and a multi-gear automatic gearbox on the development of the whole vehicle is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electric vehicles, and in particular to a power output system and method of the electric vehicle and the electric vehicle. Background technique [0002] The latest national standard "Terms and Definitions of Vehicle and Trailer Types" (GB / T 3730.1-2001) has the following definition for a vehicle: a non-rail-mounted vehicle driven by power with 4 or more wheels, mainly used for : Carrying people and (or) goods; towing vehicles carrying people and (or) goods; special purpose. Energy shortages, oil crises and environmental pollution are intensifying, which have a huge impact on people's lives and are directly related to the sustainable development of the country's economy and society. All countries in the world are actively developing new energy technologies. [0003] As a new energy vehicle with reduced oil consumption, low pollution, and low noise, electric vehicles are consider...
