  • Charge Disruption Monitoring and Notification System
    Publication number: 20130015814
    Abstract: A system and method for notifying a designated party when an electric vehicle charging operation is unexpectedly disrupted is provided. The system monitors the connection between the electric vehicle and the external battery pack charging source, issues a command to a notification system to send a notification message to the designated party when an interruption is detected, and then issues the notification message in accordance with a set of notification instructions. The notification instructions may include one or more criteria for determining whether the disruption is authorized, thus not requiring the transmittal of the notification message. Criteria for accepting the change in battery pack charging status as authorized includes user/device proximity to the vehicle, achievement of a target battery pack SOC, and location of the vehicle within a safe zone.

  • DETERMINING BATTERY DC IMPEDANCE
    Publication number: 20190283617
    Abstract: A controller for use in a battery charging system includes processing circuitry configured to perform certain tasks during battery charging operations, and other tasks during operational use of the battery. During a charging operation, the controller receives a measured DC impedance of a propulsion battery measured by a battery data acquisition and monitoring subsystem, obtains a reference DC impedance of a hypothetical battery, and determines an impedance degradation factor of the propulsion battery using the measured DC impedance and the reference DC impedance. During operational use of the propulsion battery, the controller obtains an operational reference impedance of the propulsion battery, determines a real-time effective impedance for the propulsion battery based on the impedance degradation factor and the operational reference impedance, and generates a feed-forward parameter based on the real-time effective impedance.
