Multi-parking-stall movable type vehicle wireless charging device and control method thereof

Abstract

The invention discloses a multi-parking-stall movable type vehicle wireless charging device and a control method thereof. The device is used for automatically charging electric vehicles parked at a plurality of charging positions. Each electric vehicle comprises a vehicle controller and a receiving coil. The multi-parking-stall movable type vehicle wireless charging device comprises s charging server, a guide rail, a wireless charging module, a tow chain cable and a plurality of vehicle positioning modules. The guide rail is arranged on the plurality of charging positions. The plurality of vehicle positioning modules are installed on the plurality of charging positions. The charging server supplied power to the wireless charging module through the tow chain cable. The wireless charging module is capable of freely moving on the guide rail to the position aligned with the receiving coil of the electric vehicle. The vehicle controller is in wireless connection with the charging server. The charging server is connected with the wireless charging module and the vehicle positioning modules. According to the invention, the automatic degree is high, the operation difficulty is low, the utilization rate is high, and the multi-parking-stall movable type vehicle wireless charging device can be widely applied to the charging control industry of electric vehicles.

Description

technical field [0001] The invention relates to the field of automobile charging control, in particular to a multi-slot mobile wireless charging device for automobiles and a control method thereof. Background technique [0002] Under normal circumstances, the transmission of electric energy is carried out through wires. This traditional transmission method requires corresponding current and voltage conversion control circuits, plugs, sockets and other hardware such as interfaces. However, this power transmission method is not 100% safe. In the case of high-power transmission, especially in some harsh environments, such as mining, construction sites, chemical plants and other places with harsh conditions, it is easy to cause electric leakage and electric shock. . Therefore, in recent years, many countries and regions have attached great importance to the research and development of wireless charging technology. The development of wireless charging technology can effectively ...

AI Technical Summary

Problems solved by technology

[0003] With the rapid development of automobile wireless charging technology, some large domestic and foreign automobile companies have achieved results in the research and development of automobile wireless charging technology. The current wireless charging technology needs to drive the vehicle to align with the charging transmitter coil, basically only one-to-one Charging, low utilization efficiency

Moreover, the current wireless charging methods mainly use electromagnetic induction or magnetic resonance. Both of these methods require the alignment of the receiving coil and the transmitting coil to ensure charging efficiency. Therefore, it is necessary for the driver to accurately park the vehicle at the target position to be efficient. charging, which greatly increases the difficulty of operation, resulting in prolonged charging operation time and reducing the utilization efficiency of the charging device
