Intelligent wireless charging method and system for electric vehicles

Abstract

The invention discloses an intelligent wireless charging method and system for an electric vehicle. The electric vehicle comprises a power cell. The method comprises the following steps: after the electric vehicle enters a wireless charging area, receiving a mileage input by a user; calculating a periodic charging time according to the mileage; receiving a vehicle use time input by the user; identifying a charging mode selected by the user when the periodic charging time is less than the vehicle use time; if the charging mode is an economic model, obtaining a low electricity price time within the vehicle use time; and after the power cell is started to be charged, controlling the charging duration of the power cell at a conventional electricity price period as a difference of the periodic charging time and the low electricity price time, wherein the charging time is the low electricity price time after the electric vehicle enters a low electricity price period. According to the intelligent wireless charging method for the electric vehicle provided by the embodiment of the invention, the charging time of the electric vehicle can be periodically controlled, and the user can autonomously select the charging mode, so the intelligence degree is high, and the user experience can be improved.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to an intelligent wireless charging method and system for electric vehicles. Background technique [0002] With the development of science and technology and the promulgation of relevant policies, the number of electric vehicles is increasing year by year, and the ensuing charging problem has become increasingly prominent. [0003] For wired charging, the charging cable needs to be plugged and unplugged during charging, and the charging scheme cannot be freely selected. The operation is cumbersome and dangerous. For wireless charging, in related technologies, there are mainly wireless charging systems and methods proposed for the principle of wireless charging. For example, the invention with the application number 201510297048.8 discloses a wireless charging system. The transmitting coil of the power transmitting module is a matrix-arranged coil group composed of multipl...

Problems solved by technology

For example, the invention with the application number 201510297048.8 discloses a wireless charging system. The transmitting coil of the power transmitting module is a matrix-arranged coil group composed of multiple sub-coils. During the wireless charging process, multiple sub-coils can be selectively turned on for receiving Module power supply can reduce the alignment requirements of the charged device and the wireless charging device during charging. Although it improves the charging convenience and charging efficiency, the degree of intelligence is not high and the user experience is not good.
