Electric vehicle, vertical charger and charging method thereof

Abstract

The present invention relates to a system for charging an electric vehicle and to a method for charging the electric vehicle. A charging stand which supplies electric power for charging to the electric vehicle performs user authentication or vehicle authentication for the electric vehicle to be charged, so as to prevent unauthorized charging or theft and thus enable the electric vehicle to be stably charged. In addition, a connection circuit is used as a connection cable or a connector for charging, which interconnects the vehicle and a charging side by means of a single line to enable both the vehicle and the charging side to recognize the interconnection, thus simplifying the configuration of the circuit for enabling the vehicle and the charging side to recognize the interconnection, and enabling both the vehicle and the charging side to easily recognize whether or not they are interconnected.

Description

technical field [0001] The present invention relates to an electric vehicle, a vertical charger and a charging method thereof, in particular to an electric vehicle, a vertical charger and a charging method thereof which provide a safe charging environment for charging an electric vehicle requiring long-time charging. Background technique [0002] Electric vehicles are the most likely solution to future automobile pollution and energy problems, and from this point of view, research on electric vehicles is being actively carried out. [0003] Electric vehicles (Electric vehicles: EV) are vehicles that mainly use battery power to drive AC (alternating current) or DC (direct current) motors to obtain power. They are roughly divided into battery-specific electric vehicles and hybrid electric vehicles. The electric power is used to drive the motor, and it is recharged after the power is consumed; the hybrid electric vehicle generates electricity by running the engine to charge the...

AI Technical Summary

Problems solved by technology

[0008] However, with conventional electric vehicle charging systems, users need to carry charging cables, and there is a possibility that the cable frame will be stolen

[0009] Moreover, the electric car needs to be charged for a long time, and the following problems may occur: if the cable is unplugged and connected to another car during its charging, the other car will be charged, and the cost will still be borne by the user.

[0011] However, usually both lines used to identify the interconnection as described above perform the function of identifying the connection, i.e. both lines perform the same function and thus become a duplicated setup

[0012] In the past, when one line was used to identify mutual connections in order to resolve this situation, there were cases where one side recognized the connection but the other side did not recognize the connection, that is, they could not recognize each other at the same time

[0013] In the case of using one line and recognizing the connection on both sides, it is necessary to use a communication IC (integrated circuit), so there is a problem that unnecessary and expensive parts need to be used for simply identifying the interconnected circuits
