Abstract: An energy storage system may include battery packs, such that one terminal of the battery packs is electrically coupled to a resistor representative of an isolation resistance of the battery system. The system may include a semiconductor relay switch, a plurality of resistors configured to electrically couple to the battery packs via the semiconductor relay switch, a gain field-effect transistor (FET) configured to electrically short at least one resistor of the plurality of resistors, and a control system. The control system may send a first command to the semiconductor switch to close, acquire a first voltage waveform, send a second command to the semiconductor switch to open, send a third command to the gain FET to close, send a fourth command to the semiconductor switch to close, acquire a second voltage waveform, and determine the isolation resistance based on the first voltage waveform and the second voltage waveform.

Abstract: Embodiments describe a battery system that includes a first battery module coupled to a regenerative braking system and a control module that controls operation of the battery system by: determining a predicted driving pattern over a prediction horizon using a driving pattern recognition model based in part on a battery current and a previous driving pattern; determining a predicted battery resistance of the first battery module over the prediction horizon using a recursive battery model based in part on the predicted driving pattern, the battery current, a present bus voltage, and a previous bus voltage; determining a target trajectory of a battery temperature of the first battery module over a control horizon using an objective function; and controlling magnitude and duration of electrical power supplied from the regenerative such that a predicted trajectory of the battery temperature is guided toward the target trajectory of the battery temperature during the control horizon.

Abstract: The present disclosure includes a battery module having a first electrochemical cell and a second electrochemical cell positioned adjacent to the first electrochemical cell. The battery module also includes a separator plate disposed between the first electrochemical cell and the second electrochemical cell. The separator plate includes a body comprising a first side and a second side opposite the first side. The first side is disposed adjacent a first face of the first electrochemical cell and includes a first indention. The first indention defines a first space between the first face of the first electrochemical cell and the first side of the separator plate. The first space is configured to enable swelling of the first electrochemical cell into the first space.
