Abstract: System and methods for determining performance degradation of a battery system are presented. In certain embodiments, the disclosed systems and methods may involve testing, monitoring, and/or modeling of battery system cyclic performance degradation at a single battery system operating temperature. The disclosed systems and methods may offer certain efficiencies over conventional techniques for determining cyclic degradation of a battery system. Such efficiencies may allow the disclosed systems and methods to be implemented in connection with real-time battery state estimation methods.

Abstract: A hybrid powertrain system includes a method for managing electrical charging of a DC power source, which includes determining an initial charge-sustaining SOC setpoint and an initial charge-termination SOC setpoint. The DC power source is dynamically monitored. An adjustment to a charge-sustaining SOC setpoint is determined based upon the ambient temperature, the device temperature and the SOC of the DC power source, and an updated charge-sustaining SOC setpoint is determined based upon the adjustment to the charge-sustaining SOC setpoint and the initial charge-sustaining SOC setpoint. An electric energy equalization factor α is determined, and an updated charge termination SOC setpoint can be determined based upon the electric energy equalization factor α, the updated charge-sustaining SOC setpoint and the initial charge-sustaining SOC setpoint. Charging of the DC power source is controlled based upon the updated charge-termination SOC setpoint.

Abstract: System and methods for estimating a life of a battery pack are presented. In certain embodiments, a method for estimating a life of a battery pack may include generating cell-level test data that includes measured parameters a of battery cell included in the battery pack in response to a plurality of test conditions. One or more first thermal response parameters associated with the battery cells of the battery pack may be determined. A battery cell aging model may be generated based, at least in part, on the cell-level test data and the one or more first thermal response parameters. Second thermal response parameters associated with the battery pack may be determined, and an estimated life of the battery pack may be determined based, at least in part, on the battery cell aging model and the second thermal response parameters.

Abstract: Presented are charging systems for provisioning vehicle grid integration (VGI) demand-response (DR) activities, methods for making/using such systems, and vehicles with bidirectional charging and VGI DR capabilities. A method of controlling VGI operations for a host vehicle includes a resident/remote vehicle controller receiving user-specific data input by the host vehicle's operator and crowd-sourced data output by third-party vehicles deemed comparable to and located within a predefined region of the host vehicle. A predicted battery life of the battery pack resulting from the host vehicle performing VGI operations is estimated using a non-iterative, non-recursive closed-form battery life model based on the user-specific and crowd-sourced data. The controller uses the predicted battery life to determine a value proposition indicating a predicted value and battery capacity for performing VGI operations, and commands a resident subsystem of the host vehicle to execute a control operation for the VGI operation based on the value proposition.
