Abstract: A vehicle may include battery cells of a battery and at least one controller configured to control the vehicle based on a state observation associated with the battery according to battery model parameters for the cells received from a computing device external to the vehicle and responsive to measurements relating to a battery model of the cells sent to the computing device.

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.

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. The invocation of active battery excitation may be based on a variability of estimates of a battery parameter and an age of a most recent estimate of the battery parameter. As the variability of the parameter estimates increases, the time between active battery excitation requests may decrease.

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.

Abstract: Hybrid-electric and pure electric vehicles include a traction battery comprised of many cells. During repeated charge and discharge cycles, the state of charge of the cells may vary from cell to cell. To optimize traction battery usage, it is desirable that the state of charge of the cells be equalized. Cell balancing can equalize the states of charge and improve battery performance. To achieve proper cell balancing, an accurate state of charge value should be known for each cell. An accurate state of charge value may be achieved 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. Cell balancing may be initiated and terminated according to state of charge values estimated when the conditions are satisfied.

Abstract: Some vehicle maneuvers in a hybrid electric vehicle require a high discharge current from the battery. The capacity of a battery to supply a large discharge current depends on, among other things, the recent charge and discharge history. When the demand can be predicted in advance, the vehicle is operated to aggressively charge the battery during a time period close in time to the predicted event. As a result of this aggressive charging, the battery delivers more current to satisfy the power demand without allowing the terminal voltage to decrease below a minimum level than the battery would be capable of delivering at the same state of charge following a period of rest.

By arranging extended control words of one or more REs in a plurality of superframes and different connotations of the extended control words at the same position in different superframes, the solution solves the problem that the requirements cannot be satisfied due to the limited number of control words in the protocol, and has the beneficial effect of increasing control words in the protocol.

Abstract: A hybrid or electric vehicle includes a traction battery to store and provide energy for the vehicle. The traction battery includes a number of battery cells. For effective operation of the traction battery, operating parameters, such as state of charge and battery power limits, may need to be known. The operating parameters may be a function of battery cell voltage and impedance parameters. A parameter estimation scheme may use measured cell voltages and a measured traction battery current as inputs. A current measurement bias may be modeled that incorporates measurement bias caused by asynchronous current and voltage measurements. The current measurement bias may be estimated for each cell and the value may differ between cells.

Abstract: A vehicle is disclosed comprising a battery and a controller. Projected battery impedance parameters are calculated based on predetermined parameter values and historical parameter values generated by a battery parameter estimation model. The values may be weighted according to time data associated with the historical impedance parameter values and a temperature of the battery. Recent historical impedance parameter values may affect the projected battery impedance parameter values more than older historical impedance parameter values. The model is initialized with projected parameter values at vehicle initialization. Battery power capability is calculated using the projected parameter values for a period of time following vehicle initialization. After the period of time following vehicle initialization, battery power capability is calculated using impedance parameters generated by the model. The period of time following vehicle initialization may end when the model output has converged to a stable solution.

The upper and lower limits may be adjusted based on the age of the battery.

Abstract: A vehicle having a battery pack with cells grouped into subsets and at least one controller programmed to charge and discharge the battery pack is disclosed. A control output is generated based on a pack state of charge derived from each cell's initial state of charge at vehicle activation and an electric charge accumulated or spent by less than all of the cells of each of the subsets since vehicle activation. A method of estimating battery pack state of charge is disclosed in which a pack state of charge is calculated by identifying subsets of cells having similar properties and calculating an electric charge accumulated or spent for fewer than all of the cells of each subset. A cell state of charge is calculated for all cells based on an average electric charge accumulated or spent. The pack state of charge is based on all the cell states of charge.
