creating a plan of battery usage, based on the power requirement and the identified health status of each battery in the battery pack.

7 . The computer-implemented method of claim 1 , wherein selecting a sequence of battery usage further comprises:

determining how long the battery needs to be used before switching to another battery in the battery pack; and

identifying when the battery needs to stop supplying power and be allowed to cool down.

8 . The computer-implemented method of claim 1 , wherein configuring usage of each battery individually, based on the identified health status of each battery in the battery pack, further comprises:

tracking, via sensors, heat generation with each battery in the battery pack, based on usage and cool-down time;

estimating the health status of each battery in the battery pack, based on tracking the heat generation; and

assigning a different configuration to each battery based on the estimated health status.

9 . A computer program product, comprising a tangible storage device having program code embodied therewith, the program code executable by a processor of a computer to perform a method, the method comprising:

identifying a health status of each battery in a battery pack, wherein the health status comprises power availability, and wherein monitored battery data of each battery in the battery pack is transmitted on a continuous basis;

identifying a norm for a rate of charging and a rate of cool-down required for each battery in the battery pack;

identifying how much power can be provided to a vehicle in different time ranges;

configuring usage of each battery individually, based on the identified health status of each battery in the battery pack, so that each battery in the battery pack does not generate more than an assigned temperature limit and can get required cool-down time after usage;
