Abstract: A system for estimating a state-of-charge of a battery assembly includes a sensor cell and an estimator circuit. The sensor cell is coupled in series to the battery assembly. The battery assembly has an assembly battery chemistry and the sensor cell has a sensor battery chemistry, and the assembly battery chemistry is different than the sensor battery chemistry. The estimator circuit is operational to acquire a sequence of current sensor cell state-of-charges based on a sensor cell model and a sequence of sensor voltages across the sensor cell, calculate a sequence of current battery assembly state-of-charges based on the sequence of current sensor cell state-of-charges, and calculate an estimated battery assembly state-of-charge of the battery assembly and an estimated sensor cell state-of-charge of the sensor cell by filtering in parallel the sequence of current battery assembly state-of-charges and the sequence of current sensor cell state-of-charges.

Abstract: Simultaneous parallel charging of a first and second electrical energy storage devices coupled to a charge source is carried out by directly coupling the charge source to one of the first ESD and the second ESD and through a DC to DC converter to the other of the first ESD and the second ESD. The charge source provides a current that is allocated to the two ESDs by controlling the DC to DC converter. Priority of charging may be given to either ESD.

Abstract: A system in a vehicle includes a controller to implement a neural network to provide current commands based on inputs. The inputs include a torque input. The system also includes a current controller to provide a three-phase voltage through an inverter based on the current commands from the controller. An electric traction motor provides drive power to a transmission of the vehicle based on injection of the three-phase voltage. The current commands resulting from implementation of the neural network are corrected based on estimated torque resulting from the injection of the three-phase voltage to the electric traction motor.
