摘要： 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.

摘要： The present disclosure includes a system having a battery module, where the battery module includes a housing having a top side, a lateral side, and an edge extending along and between the top side and the lateral side. The battery module also includes electrochemical cells disposed in the housing, and a heat sink disposed on the lateral side of the housing. A fan is disposed over the top side of the housing. A hood includes a first hood portion disposed over the top side of the housing and the fan and a second hood portion coupled to the first hood portion and disposed over the lateral side of the housing, where the hood defines an airspace between the hood and the housing and the hood is configured to guide an airflow through the airspace from the fan on the top side of the housing, over the edge between the top side and the lateral side of the housing, and over the heat sink disposed on the lateral side of the housing.

摘要： A battery module includes a housing having a top side, a bottom side, and an inside between the top side and the bottom side. The battery module also includes electrochemical cells disposed in one or more stacks in the inside of the housing. The electrochemical cells are spaced apart from each other to enable an airflow between the electrochemical cells. The battery module includes a fan on an outside of the housing and a hood disposed over the fan and configured to contact the housing to direct the airflow through an entry point into the inside of the housing. The battery module includes a vent fluidly coupling the inside and the outside of the housing. The vent vents the airflow from the inside of the housing to the outside of the housing. The battery module includes flow guide features configured to guide the airflow along the electrochemical cells.
