Description

technical field [0001] The invention relates to a charging device, which is a magnetic coupling resonant wireless energy charging device for a rechargeable battery of an electric wheelchair. Background technique [0002] At present, electric wheelchairs are mainly powered by rechargeable batteries to perform various necessary actions. The traditional charging method is to charge the battery through wire connection. Although this method can meet the needs of users, it is inconvenient for users to plug and unplug the wires frequently for special people who use wheelchairs. The use of wireless charging can not only avoid frequent plugging and unplugging of the power supply, solve the messy placement of charging wires, but also separate the charging equipment from the power supply, reducing the risk factor and greatly facilitating the lives of special people. [0003] Wireless power transmission mainly includes three methods: electromagnetic induction coupling, radiation and ma...
