Battery Management Systems and Methods

A battery management system, the battery management system comprising:

• a battery sensor coupled to a battery comprising at least two battery modules;
• a load sensor coupled to a load;
• an actuator coupled to the at least two battery modules and the load;
• and
• a controller coupled to the battery sensor, the load sensor, and the actuator, the controller comprising at least one processor and at least one memory, the at least one memory comprising instructions executed by the at least one processor to:
• receive a battery profile comprising a plurality of operating parameter sets, each operating parameter set comprising a preferred discharge rate, a preferred depth of discharge range, and at least one environmental factor;
• receive load information about the load from the load sensor;
• receive battery operating information from the battery sensor;
• select a target operating parameter set included in the plurality of operating parameter sets based on the battery operating information;
• determine a number of battery modules needed to supply the load based on the load information, the battery operating information, and target operating parameter set;
• select a group of battery modules included in the battery based on the number of battery modules and the battery operating information;
• and
• instruct the battery to supply the load using the group of battery modules.

A battery management method comprising:

• receiving load information about a load from a load sensor coupled to the load;
• receiving battery operating information from a battery sensor coupled to a battery comprising a plurality of battery modules;
• determining a number of battery modules needed to supply the load and operate each battery module included in the battery at or below a preferred discharge rate based on the load information and the battery operating information;
• selecting a group of battery modules included in the battery based on the number of battery modules and the battery operating information, each battery module included in the group of battery modules having a current depth of discharge within a preferred depth of discharge range;
• and
• instructing the battery to supply the load using the group of battery modules.
