Managing top-off charging and discharge testing of battery packs to optimize capacity

A system for managing battery capacity within a battery system, the system comprising:

• a memory;
• and
• one or more processors communicatively coupled to the memory, wherein the system performs a method comprising:
• obtaining, by the one or more processors, data representative of a number (N) of battery packs in the battery system;
• ascertaining, by the one or more processors, a battery pack self-discharge time interval (TD) from full-charge to a partially discharged threshold for initiating top-off charging;
• determining, by the one or more processors, a charge-staggering time interval (TS), the determining using the number (N) of battery packs in the battery system and the ascertained battery pack self-discharge time interval (TD);
• and
• staggering, by the one or more processors, top-off charging of the battery packs of the N battery packs in the battery system using, at least in part, the charge-staggering time interval (TS).

A computer program product for managing battery capacity within a battery system, the computer program product comprising:

• a computer-readable storage medium having program instructions embodied therewith, the program instructions being executable by one or more processors to cause the one or more processors to:
• obtain, by the one or more processors, data representative of a number (N) of battery packs in the battery system;
• ascertain, by the one or more processors, a battery pack self-discharge time interval (TD) from full-charge to a partially discharged threshold for initiating top-off charging;
• determine, by the one or more processors, a charge-staggering time interval (TS), the determining using the number (N) of battery packs in the battery system and the ascertained battery pack self-discharge time interval (TD);
• and
• stagger, by the one or more processors, top-off charging of the battery packs of the N battery packs in the battery system using, at least in part, the charge-staggering time interval (TS).
