Abstract
An electronic device may include a power management subsystem that soft-starts freshly charged batteries upon connection. The device may be configured to operate on power from a number of batteries less than the greatest number of batteries that may be concurrently connected. Because the soft-start reduces current inrush upon connection of a fresh battery, the device may continue operating as fresh batteries are connected and depleted batteries are disconnected.
Claims21
A power delivery system, comprising:
- a battery connection;
- and
- a soft-start circuit connected to the battery connection and a main power bus, wherein the soft-start circuit is configured to:
- provide increasing levels of power to the main power bus when a battery having a voltage level higher than a voltage level on the main power bus is connected to the battery connection, and
- prevent power delivery to the main power bus from the battery when the voltage level of the battery is less than the voltage level on the main power bus.
2 more elements
A power delivery system, comprising:
- a first electrical connection;
- a second electrical connection;
- wherein each of the first electrical connection and the second electrical connection includes a battery connection;
- and
- an integrated circuit having stored thereon software instructions that, when executed, will cause the integrated circuit to restrict current draw from a battery connected to the first electrical connection or second electrical connection if the voltage of the battery exceeds a threshold voltage.
