| 词条 | Conductive wireless charging |
| 释义 |
Conductive power transfer uses a conductor to connect two electronic devices in order to transfer energy.[1] It is therefore not a form of wireless power transfer, which explicitly does not use conductors. In the area of cellular phone chargers, phones are equipped with an attachment such as a sleeve which, when placed on the charging board, transfers energy to the phone's battery. Conductive charging systemInductive and conductive charging are two types of wireless charging. Again, this is not to be confused with "wireless power transfer". Conductive charging requires a physical connection between the electronic device's battery and the power supply.[3] The need for a metal-to-metal connection between the charger and the device requiring charging is one of the main drawbacks of this method.[4] To accomplish this without the use of physical cords connected to wall outlets, special attachments are made from electronic devices which are fitted with technology that can detect when the device makes connection with the power source, often a charging base. Conduction based wireless accessories may include changeable backs for cellular phones, special sleeves and attachable clips.[1] The electronic devices, fitted with these accessories, are placed on a charging base. The base can detect when a compatible device has been placed on it and begin the battery charging process. These charging bases are usually designed to be able to distinguish between human and metal contact so that there is no risk of electrocution.[2] Electric vehicles{{see also|Ground-level power supply}}Honda studies charge-on-the-move for conduction between vehicle rollers and road power, with 100 kW of power (DC 375 V, 300 A) at a vehicle speed of 70 km/h, and possibly higher.[5] Stanford scientists have developed a way to wirelessly deliver electricity to moving objects, the technology that could one day charge electric vehicles and personal devices.[6] See also
