BATTERY MODULE ACTIVE THERMAL MANAGEMENT FEATURES AND POSITIONING

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.
