  • Patent number: 9718455
    Abstract: Hybrid-electric and pure electric vehicles include a traction battery. During vehicle operation, impedance parameters of the traction battery may be estimated. To ensure accurate estimation results, certain persistent excitation criteria may be met. These conditions may not always be met, in which case active excitation of the traction battery power demand may be initiated. During periods of generally constant battery power demand in which a predetermined range of frequency component amplitudes of battery power demand is less than a predetermined magnitude, active excitation may be desired. A controller may cause at least one of the frequency component amplitudes to exceed the predetermined magnitude without affecting acceleration of the vehicle. Battery power demand may be affected by operation of an electric machine and an electrical load. An engine and a wheel brake may be operated to offset changes in battery power demand such that driver wheel output power is not affected.

  • Patent number: 9716294
    Abstract: A battery controller with monitoring logic for a model-based battery control of a battery performs battery current characterizing, parameter and state variable abnormality detection, and bound checking of error signals between measured and predicted output variables to generate an output. Switching between closed-loop operation (i.e., the model-based battery control) and open-loop operation (i.e., a traditional battery control) is done based on the output of the monitoring logic such that closed-loop stability and performance are reasonably guaranteed.

  • Publication number: 20170113565
    Abstract: A vehicle includes a traction battery and a controller coupled to the traction battery and having a memory, the controller being programmed to control the traction battery based on a difference between a total resistance indicated by voltage and current at a first operating condition and a battery cell resistance associated with the first operating condition previously stored in the memory, the difference being indicative of a wiring resistance associated with electrical connectors such as wires, cables, bus bars, and the like of the battery. The battery or the vehicle may be controlled in response to the adaptively determined wiring resistance by adjusting subsequent voltage or current determinations used to determine state of charge and battery capacity and/or to control charging or discharging of the battery and selection of various vehicle operating modes.

  • Patent number: 9539912
    Abstract: Hybrid-electric and pure electric vehicles include a traction battery comprised of many cells. Controlling a battery system may require that a battery state of charge and a battery capacity be known. The state of charge and battery capacity values may be derived from estimated traction battery model parameters. The accuracy of the estimated model parameters depends on the signal richness and convergence properties of the estimation scheme. Accurate model parameters may be estimated when a persistent excitation condition and an estimation convergence condition are met. If the conditions are not met, active excitation of the battery may be performed to improve the chances of meeting the conditions.

  • Patent number: 9523317
    Abstract: Methods and systems are provided for relieving excess fuel tank vacuum in a vehicle. In one example, responsive to a fuel tank vacuum above a threshold or a rise in fuel tank vacuum level being higher than a threshold rate, a canister purge valve is opened to dissipate the fuel tank vacuum into an engine intake manifold while the engine is combusting, and the amount of intake air inducted into the intake manifold is adjusted such that air/fuel ratio errors are reduced. In this way, fuel tank vacuum may be relieved under engine operating conditions wherein the likelihood of air/fuel ratio errors are high, thus enabling rapid relief of fuel tank vacuum such that fuel tank degradation can be reduced and fuel system integrity can be better maintained.
