Wireless charging device, system and method

Abstract

The invention provides a wireless charging device, system and method. The wireless charging device includes a charging coil, a heat dissipation tray, a tray assembly, a lifting mechanism, a transverseand longitudinal moving device and a communication sensing module; the lifting mechanism drives the tray assembly to rise or fall so as to drive the charging coil to rise or fall; the communication sensing module judges whether the charging coil is aligned with an electric receiving coil of an electric vehicle or not; if the charging coil is not aligned with the electric receiving coil of the electric vehicle, the transverse and longitudinal moving device drives the heat dissipation tray to move so that the charging coil on the heat dissipation tray is aligned with the electric receiving coil; and when the charging coil is aligned with the electric receiving coil of the electric vehicle, the charging coil charges the electric receiving coil. According to the wireless charging device, system and method, the automatic alignment of the charging coil and the electric receiving coil can be realized through the transverse and longitudinal moving device, and meanwhile the efficiency of wireless charging is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless charging, in particular to a wireless charging device, system and method. Background technique [0002] With the continuous development of battery technology, the energy density of batteries is getting higher and higher, the mileage of a single charge of pure electric vehicles continues to increase, and pure electric vehicles are becoming more and more popular. The charging piles installed in parking lots and parking spaces in various places not only take up space, but also pose great safety hazards. When parking, it is easy to bump into the charging piles, and the wind and sun can easily lead to damage to the outer protection of the charging piles, and the aging of the cable skin and loss of insulation. Capability; problems such as charging gun throwing and leakage caused by unattended management abound. As the power capacity of charging piles increases, charging cables become thicker a...

AI Technical Summary

Problems solved by technology

The charging piles installed in parking lots and parking spaces in various places not only take up space, but also pose great safety hazards. When parking, it is easy to bump into the charging piles, and the wind and sun can easily lead to damage to the outer protection of the charging piles, and the aging of the cable skin and loss of insulation. Ability; problems such as charging gun throwing and leakage caused by unattended management abound

As the power capacity of charging piles increases, charging cables become thicker and heavier, making it difficult for physically weak users to operate, or the clothes are stained by cables

Charging in rainy days and winter brings great inconvenience and safety hazards to users

[0003] Wireless charging can solve the above problems very well. Due to some technical limitations, the existing wireless charging technology has problems such as low efficiency of wireless charging, difficulty in aligning the charging coil with the vehicle power receiving coil, etc.
