    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 with a housing having first and second ends and first and second lateral sides between the first and second ends. The battery module includes prismatic electrochemical cells and a cooling duct having first and second segments. A first body of the first segment extends along the first lateral side of the housing and includes a first opening to environment. A second body of the second segment extends along the second lateral side of the housing and includes a second opening to the environment. The first and second openings are proximate to the second end of the housing. The battery module includes a fan disposed on the first end of the housing. The fan is fluidly coupled to the cooling duct and provides airflow through the first and second openings and along the first and second bodies.
