Flexible cell battery systems and methods for powering information handling systems
First Claim
1. An information handling system, comprising:
- a system load;
a battery system having a main battery conductor path coupled to power the system load, the battery system comprising;
battery cell circuitry including multiple battery cells coupled together in the main battery conductor path in at least one of series relationship, parallel relationship, or a combination thereof,one or more switching devices coupled to selectively bypass or remove one or more of the multiple battery cells from the main battery conductor path of the battery cell circuitry;
at least one processing device coupled to control the one or more switching devices to selectively remove one or more of the multiple battery cells from the main battery conductor path of the battery cell circuitry.

Abstract
The number of battery cells connected together in a main battery conductor path of a multiple cell battery system of an information handling system may be varied in real time based on one or more operating conditions (e.g., system load power consumption, battery cell failure, etc.) of the information handling system. Defective battery cells may be bypassed such that the defective battery system may continue to operate and power an information handling system at a lower voltage, e.g., either temporarily, permanently or temporarily until the user procures a suitable replacement battery system. Interconnection of cells of a non-defective multiple cell battery system may also be selectively re-arranged to vary battery system voltage at particular times or during particular information handling system operation modes.
