Load Allocation for Multi-Battery Devices

A computer-implemented method comprising:

• determining, for a device having multiple batteries, a current amount of load power being consumed by the device to operate;
• estimating, for a future point in time, an expected amount of load power that the device will consume to operate;
• receiving, for the multiple batteries, information concerning respective efficiencies at which the multiple batteries are capable of providing power;
• determining, based on the current and expected amounts of load power and the respective efficiencies, an allocation of the load power to the multiple batteries effective to maximize an efficiency at which the multiple batteries power the device until the future point in time;
• and
• drawing, from each of the batteries and based on the determined allocation, a respective portion of the current amount of load power to for device consumption.

A system comprising:

• multiple batteries configured to provide power to enable operation of the system;
• switching circuitry configured to enable the power to be drawn from each of the multiple batteries;
• sensing circuitry configured to measure load power consumed by the system to operate;
• and
• a load manager configured to perform operations comprising:
• determining an amount of the load power being consumed by the system;
• determining, for each of the multiple batteries, a respective efficiency at which each of the multiple batteries is capable of providing power;
• determining, based on the respective efficiencies of the multiple batteries, an allocation of the load power to the multiple batteries effective to maximize an efficiency at which the multiple batteries power the system;
• and
• distributing, based on the determined allocation, respective portions of the load power to each of the multiple batteries.
