Managing charging of a battery of an information handling system

An information handling system comprising a processor having access to memory media storing instructions executable by the processor to perform operations, comprising:

• determining that a battery of the information handling system is in a standard charging mode;
• in response to determining that the battery is in the standard charging mode:
• for a first time interval, charging the battery with a first power provided by a power supply unit (PSU), the first power associated with the standard charging mode;
• determining that the first time interval has elapsed;
• in response to determining that the first time interval has elapsed, for a second time interval after the first time interval:
• determining whether the battery is in a constant voltage mode or a constant current mode;
• in response to determining that the battery is in the constant voltage mode:
• determining a current voltage of the battery;
• determining an offset voltage based on the current voltage of the battery and a current output voltage of the PSU;
• and
• charging the battery with a second power provided by the PSU, the second power based on the offset voltage.

A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:

• determining that a battery of an information handling system is in a standard charging mode;
• in response to determining that the battery is in the standard charging mode:
• for a first time interval, charging the battery with a first power provided by a power supply unit (PSU), the first power associated with the standard charging mode;
• determining that the first time interval has elapsed;
• in response to determining that the first time interval has elapsed, for a second time interval after the first time interval:
• determining whether the battery is in a constant voltage mode or a constant current mode;
• in response to determining that the battery is in the constant voltage mode:
• determining a current voltage of the battery;
• determining an offset voltage based on the current voltage of the battery and a current output voltage of the PSU;
• and
• charging the battery with a second power provided by the PSU, the second power based on the offset voltage.
