Abstract: A vehicle and control method include a traction battery, a temperature sensor, current sensor, and voltage sensor associated with the traction battery, an electric machine powered by the traction battery to provide propulsive power to the vehicle, and a controller configured to control at least one of the electric machine and the traction battery in response to a battery state of charge (SOC) estimated using a battery model having parameters including a first resistance in series with a second resistance and a capacitance in parallel to the second resistance. The battery model parameters are adjusted during vehicle operation using a Kalman filter and reinitialized to new values in response to a vehicle key-on, in response to a change in the battery current exceeding a corresponding threshold, and/or in response to any of the parameter values crossing an associated limit.

Abstract: A deterioration evaluation apparatus for a secondary battery, which evaluates a degree of deterioration of the secondary battery of a hybrid vehicle including an engine that outputs a driving power, a motor that outputs a driving power, and the secondary battery configured to exchange an electric power with the motor, includes one or more processors configured to evaluate the degree of deterioration of the secondary battery based on a first relationship. The first relationship is set by using an accelerator operation amount and an operation point. The operation point includes a rotation speed of the engine and a load factor of the engine. The first relationship is a relationship between the operation point and a load on the secondary battery when the engine is operated at the operation point.

Abstract: Degradation degree table is a degradation degree table that describes a degradation degree of a secondary battery when the secondary battery is charged or discharged at a prescribed current rate with prescribed frequency. Degradation degree table describes the degradation degree in each of a plurality of state of charge (SOC) regions obtained through division of an SOC range of the secondary battery into the plurality of regions. Upper limit current determining part determines an upper limit current value to be used as a current rate at a time of charge or discharge, based on an estimated SOC and a target degradation degree with reference to degradation degree table.

Abstract: In one or more embodiments of the present invention, one or more processors receive a fuel sensor reading from a fuel sensor on a vehicle. The processor(s) receive an environmental state of a route being taken by the vehicle to a destination and a biometric sensor reading that describes a biometric state of a driver of the vehicle. The processor(s) determine whether the remaining fuel will be sufficient for the vehicle to reach the destination subject to the constraints of the environmental state of the route being taken by the vehicle and the biometric state of the driver of the vehicle, and then modify an appearance of a fuel gauge on the vehicle based on whether the remaining fuel will be sufficient for the vehicle to reach the destination.

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.
