Disclosed is a battery system comprising a solid-state relay assembly comprising a device-side driver circuitry having a device-side switching device, a battery-side driver circuitry having a battery-side switching device, a first recirculation driver circuitry, a first recirculation switching device, a second recirculation switching device, and a second recirculation driver circuitry.

Solid-state relay dedicated recirculation path systems and methods

One embodiment of the present disclosure describes a battery system including a battery module with a first and second cell group connected in series; and a cell control unit communicatively coupled to a plurality of sensors, in which the cell control unit includes a first analog-to-digital converter that outputs a first cell group voltage; a second analog-to-digital converter that outputs a second cell group voltage; outputs a measured battery module voltage; and logic circuitry that determines a calculated battery module voltage based at least in part on the first cell group voltage and the second cell group voltage; and determines whether a fault is expected to be present in the cell control unit, the battery module, or both based at least in part on the measured battery module voltage and the calculated battery module voltage.

Cell control unit fault detection systems and methods

One embodiment of the present disclosure describes a battery system that includes a battery string with a first and second battery module; and a battery control system. The battery control system includes a first cell control that determines first module level operational parameters related to operation of the first battery module; a second cell control that determines second module level operational parameters related to operation of the second battery module; a string control unit communicatively that determines string level operational parameters related to operation of the battery string based at least in part on the first and second module level operational parameters; and a system control unit that determines system level operational parameters related to operation of the battery system based at least in part on the string level operational parameters; and controls operation of the battery system based at least in part on the system level operational parameters.

Hybrid battery control system architecture systems and methods

One embodiment of the present disclosure describes a battery system that includes a battery string with a first and second battery module connected in series; and a battery control system that includes a cell control unit electrically coupled to the first battery module, in which the first cell control unit determines first module level operational parameters related to operation of the first battery module; an integrated string control unit electrically coupled to the second battery module, in which the integrated string control unit determines second module level operational parameters related to operation of the second battery module; determines string level operational parameters related to operation of the battery string based at least in part on the first module level operational parameters and the second module level operational parameters; and controls operation of the battery string based at least in part on the string level operational parameters.

Integrated string control unit systems and methods

The present disclosure includes a battery system that may include a first terminal and a second terminal electrically coupled to an electronic component. The system may also include a current source electrically coupled to the first terminal. The system may also include a control system that may direct an asynchronous current from the current source to the first terminal according to a pattern and receive a current signal status from a current detector. The current signal status is associated with a second current received via the second terminal. The control system may disconnect the electronic component from the first terminal or the second terminal when the current signal status does not correspond to the pattern.
