  • Cabin venting system and method for an electrified vehicle
    Patent number: 10696133
    Abstract: A method according to an exemplary aspect of the present disclosure includes, among other things, detecting a battery fault of a battery of an electrified vehicle, activating a HVAC system ON, commanding the HVAC system to a fresh air mode, communicating fresh air into a passenger cabin, and expelling battery vent byproducts from the passenger cabin through at least one air extractor vent during key-on or key-off states.
    Type: Grant

  • Method for determining the deterioration of a battery
    Patent number: 7554330
    Abstract: This objective is achieved according to the present invention in that in a method for determining the deterioration of a battery, the charge and discharge cycles of the battery are measured by number and depth of the charge/discharge. For each of the charge and discharge cycles, a characteristic deterioration value is determined on the basis of a deterioration curve that is characteristic of the specific battery type. These individual characteristic deterioration values are then summed up to obtain the deterioration of the battery.
