Abstract

An energy device control system may include an energy source enclosure that can be coupled with external loads via first external connectors outside of the energy source enclosure. The system also may include an external control device coupled with the energy source enclosure via second external connectors such that the external control device is galvanically isolated from energy device cells inside the energy source enclosure. The external control device may communicate with internal control components of the energy source enclosure via the second external connectors to control charging and/or discharging of the device cells via the first external connectors.
