First Claim
Patent Images
1. A power storage adapter (PSA), comprising:
- a PSA port;
a PSA battery; and
a PSA controller having access to memory media storing instructions executable by the PSA controller to;
receive an indication of a peak shift associated with an alternating current (AC) line power source, the indication specifying that the power storage adapter is to cease drawing electrical power from the AC line power source;
determine that a state of charge of the PSA battery is greater than a recharging state of charge;
in response to the indication and when the power storage adapter is electrically connected to the AC line power source, electrically disconnect the power storage adapter from the AC line power source.

Abstract
A power storage adapter may use a peak shift operation method when supplying electrical power from an AC line power source to a portable information handling system and the power storage adapter receives an indication of a peak shift associated with the AC line power source. In particular, the power storage adapter may cease drawing power from the AC line power source and begin supplying electrical power from a battery included with the power storage adapter to the portable information handling system.

11. A method for peak shift operation, the method comprising:
-
receiving, by a PSA controller of a power storage adapter, an indication of a peak shift associated with an AC line power source of the power storage adapter, the indication specifying that the power storage adapter is to cease drawing electrical power from the AC line power source; determining, by the PSA controller, that a state of charge of a PSA battery of the power storage adapter is greater than a recharging state of charge; in response to the indication and when the power storage adapter is electrically connected to the AC line power source, electrically disconnecting, by the PSA controller, the power storage adapter from the AC line power source. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
