Abstract

The invention discloses a wireless charging system for an electric car. The wireless charging system for the electric car comprises a wireless power supply device and a wireless powered device, wherein the wireless power supply device is arranged on the ground, and the wireless powered device is arranged on the electric car. The wireless power supply device includes a power supply module, a TS type resonant compensation network and an energy transmitting coil, wherein the energy transmitting coil is arranged on the ground, an input end of the power supply module is connected to a power grid, and the output end of the power supply module is connected with the energy transmitting coil through the TS type resonant compensation network. The wireless powered device comprises a charging battery,a rectification module and an energy pick-up coil for receiving energy transmitted wirelessly by the energy transmitting coil, wherein the output end of the energy pick-up coil is connected to the charging battery by the rectification module. An inner tube of the wireless charging system for the electric car effectively increases the output voltage gain and transmission power of the wireless charging system for the electric car.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a wireless charging system for electric vehicles. Background technique [0002] At present, the charging of electric vehicles basically adopts the wired charging method for charging. The wired charging method is easily affected by environmental changes, the wiring cost is high, and frequent plugging and unplugging operations can easily lead to loose contacts and pose a safety hazard. With the development of power electronics technology, electric vehicle charging technology has developed towards the direction of non-contact charging technology. [0003] Non-contact charging refers to wireless energy transmission through the electromagnetic field as the medium, no leakage interface, and has the advantages of saving consumables, safe and flexible operation, and not easily affected by weather and environmental factors, but the main disadvantage of non-contact chargi...
