Abstract: A vehicle including a hybrid battery pack includes a first battery pack and a second battery pack. The first battery pack has a higher energy density than the second battery pack. The second battery pack has a higher power density than the first battery pack. A power inverter module is connected between the hybrid battery pack and a motor generator unit (MGU) that is connected to a powertrain of the vehicle. The power inverter module is configured to regulate power flow between the hybrid battery pack and the MGU. A battery management module is configured to: control switching of the power inverter module; selectively charge and discharge at least one of the first battery pack and the second battery pack; and selectively charge the first battery pack with power from the second battery pack.

Abstract: A non-integrated monitoring device and method for monitoring a subject vehicle includes monitoring, via a non-integrated sensor, a physical parameter being emitted from the subject vehicle. The physical parameter being emitted from the subject vehicle is analyzed to determine a dynamic signature for the subject vehicle. A baseline signature for the subject vehicle is obtained, and compared to the dynamic signature for the subject vehicle. Occurrence of a fault in a subsystem of the subject vehicle is detected based upon the comparing of the baseline signature for the subject vehicle and the dynamic signature for the subject vehicle, and the occurrence of the fault is communicated to an operator of the subject vehicle.
