Problems solved by technology

Therefore, there is a problem that when the in-wheel electric bus starts, the check waiting time and the control time become long
However, this approach increases the number, size or cost of the individual components
Therefore, this method has a negative impact on system optimization

Abstract

A control method for shortening a start time of an electric vehicle quickly removes electricity remaining in a system without adding a separate component. The control method includes comparing a DC-link voltage in an inverter for driving a driving motor with a first reference value in a state in which the connection between a main battery and a vehicle system is released; checking a remaining voltage in the vehicle system and comparing the checked remaining voltage with a second reference value, when the DC-link voltage in the inverter is no less than the first reference value; removing the remaining voltage by operating an electric load in the vehicle so as to consume remaining electricity in the vehicle system, when the remaining voltage is no less than the second reference value; and connecting the main battery to the vehicle system by turning on a pre-charge relay and a main relay.

Description

technical field [0001] The present disclosure relates to a control method for shortening a starting time of an electric vehicle. More particularly, the present disclosure relates to a control method capable of shortening a start-up time of an electric vehicle by quickly removing surplus power in a system without adding separate components. Background technique [0002] In recent years, green cars that can replace existing internal combustion engine cars are being actively developed due to high oil prices, carbon dioxide emission regulations, and the like. Manufacturers have commercialized or will commercialize electric vehicles that travel by driving an electric motor and hybrid vehicles that use an internal combustion engine and an electric motor as drive sources. [0003] Among electric vehicles, an in-wheel motor vehicle is being developed in which an electric motor (drive motor) is mounted on each wheel and uses battery power as a power source. An in-wheel motor vehicl...
