A second battery has a positive terminal coupled to the interface, and a negative terminal coupled to the reference terminal through a second switch, and to the first battery's positive terminal through a third switch. A control circuitry controls the switches such that the device has multiple operation modes including at least a one-battery charging mode and a two-battery-in-series charging mode. In the one-battery charging mode, the circuitry turns off the third switch, and controls the other switches such that one battery is charged by the input power. In the two-battery-in-series charging mode, the control circuitry turns on the third switch and turns off the other switches, such that two batteries are charged by the input power."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Managing power in a portable device comprising multiple batteries","description":"In a portable device, a first battery has a positive terminal coupled to, through a first switch, an interface used to receive input power, and a negative terminal coupled to a reference terminal.
