Technical Field

The invention relates to the technical field of vehicles, in particular to a large truck.

Background

Vehicles use electrical energy to move objects. We use ton and hundred kilometers of power consumption as a measure of the efficiency of electric energy usage. And the power consumption of the passenger car per ton per hundred kilometers is about 11-15 degrees according to the current Ministry of industry and communications test data. We refer to the mass proportion of driver, passenger and cargo in a 1 ton moving object as the vehicle payload rate. The mass ratio of energy storage components such as batteries and fuel oil is called energy storage mass ratio. The mass ratio of energy conversion components such as motors, engines, generators, transmissions and the like is called energy conversion mass ratio. The goal of the design of an electric vehicle is to increase the payload rate and reduce the energy storage and conversion mass fraction.

On the aspect of how to lower the life cycle use cost, the fuel vehicle needs to consider fuel saving, the pure electric vehicle needs to consider how to reduce the vehicle purchasing cost, and the energy use efficiency of the pure electric vehicle has little influence on the full life cycle cost.
