US 12,005,806 B2 · Dynamic control of configurations of electrical circuits

Abstract

Systems and methods for dynamic control of a configuration of electrical circuits are provided. An example system includes a plurality of electric power sources and a plurality of switches configured to connect and disconnect some of the electric power sources. The system may include a controller coupled to the switches. The controller may be configured to enable and disable the switches to cause a change in a configuration of the connections between the electric power sources. The electric power sources can include at least one generator and at least two batteries. The controller can be further configured to cause a change in the configuration to connect the two batteries in series to a load for discharging and connect the two batteries in parallel to the generator for recharging.
