In some examples, a system includes a primary side with a charger and a first battery and a secondary side with a second battery. The charger on the primary side can charge both the first battery and the second battery. A hinge resistance is between the primary side and the secondary side. The primary side includes a feedback controlled active device in a current path of the first battery that compensates for the hinge resistance, for connector resistances, or for battery impedances in a current path of the second battery.

Balanced charge and discharge control for asymmetric dual battery system

In some examples, an apparatus includes a battery and a dynamic voltage source coupled in series with the battery. The dynamic voltage source is to maintain (or clamp) a system voltage from going below a minimum system voltage.

Turbo support for systems with limited battery power

Techniques are provided for managing power delivery to multiple universal serial bus (USB) type-C ports of a desktop computer system. In an example, a method can include providing a first power level to a USB power delivery controller during a non-sleep mode operation of the desktop computer, and providing a second power level to the USB power delivery controller when the computer is in a sleep mode, the second power level configured to provide default charge power to a connected device when the computer is in the sleep mode.

Flexible multiport USB type-C power management

A battery charger for charging a battery with voltage from an input supply and method for using are disclosed. The battery charger may comprise a power path (e.g., one or more circuit stages, a step down stage, a step up stage, etc.) to drive the battery during a pulse charging sequence in a first mode and to reverse power flow from the battery when operating in a boost mode during the pulse charging sequence. An energy storage component may be coupled to the power path to capture pulse discharge energy during the pulse charging sequence when the circuit stage is operating in the boost mode.
