Abstract
A vehicle includes a propulsion system having multiple electric motors. A battery system is connected to the electric motors via a direct current to direct current (DC-DC) converter and an inverter. The battery system includes a battery assembly having a plurality of battery modules. Each of the battery modules has multiple individual battery cells arranged in battery packs, a set of sensors configured to monitor a set of parameters of each battery pack, and a plurality of battery pack mounts. Each battery pack mount includes a base plate and a top plate and an actuator configured to alter a distance between plates. A monitoring unit is configured to monitor a value representative of a battery pack pressure, determine whether the value falls within a pressure threshold window, and maintain the value within the pressure threshold window by actively altering the battery pack pressure.
