More Information
Summary:A battery system includes: first and second positive terminals and a negative terminal; switches; at least two battery modules, each of the battery modules including at least three strings of battery cells configured to, at different times be: connected in series and to the first positive terminal via first ones of the switches; connected in parallel and to the second positive terminal via second ones of the switches; and disconnected from both of the first and second positive terminals; and a switch control module configured to: receive temperatures of the strings of battery cells, respectively; determine temperatures of the battery modules, respectively, based on the temperatures of the strings of battery cells of that battery module; and selectively actuate the switches based on at least one of: minimizing an error between the temperatures of the strings of battery cells; and minimizing an error between the temperatures of the battery modules.
