摘要： USB charger apparatus and chargeable electronic devices are presented in which the device and charger use USB cable data lines to establish a bidirectional communications connection, and the charger provides charger capability information to a master controller of the electronic device via the communications connection. The device controller preferentially selects a fastest charging match between the charger capability information and device charging capability information, and sends configuration information through the communications connection to set the power supply level of the charger. The charger communicates power supply status information to the electronic device, and the device can reconfigure the charger power supply level accordingly.

摘要： A power supply circuit, a charging-discharging circuit and an intelligent terminal are provided. The power supply circuit includes a lithium-ion battery unit having a silicon anode and a lithium-ion battery unit having a carbon anode. The lithium-ion battery unit having the silicon anode is connected in series with the lithium-ion battery unit having the silicon anode, cooperatively supplying power to the to-be-powered unit. A battery system of the intelligent terminal is formed by the lithium-ion battery unit having the silicon anode and the lithium-ion battery unit having the carbon anode and supplies power to the to-be-powered unit. Therefore, constant voltage performance of the lithium-ion battery unit having the carbon anode is utilized effectively, further large capacity and large power margin at low supply voltage of the lithium-ion battery unit having the silicon anode is utilized effectively.
