Title: Alternator control for battery charging

Abstract

In accordance with an aspect of the present disclosure, an electrical system for an automotive vehicle has an electrical generating machine and a battery. A set point voltage, which sets an output voltage of the electrical generating machine, is set by an electronic control unit (ECU). The ECU selects one of a plurality of control modes for controlling the alternator based on an operating state of the vehicle as determined from vehicle operating parameters. The ECU selects a range for the set point voltage based on the selected control mode and then sets the set point voltage within the range based on feedback parameters for that control mode. In an aspect, the control modes include a trickle charge mode and battery charge current is the feedback parameter and the ECU controls the set point voltage within the range to maintain a predetermined battery charge current.

Advanced Integrated Traction System

Technical Report Smith, Greg; Gough, Charles

The United States Department of Energy elaborates the compelling need for a commercialized competitively priced electric traction drive system to proliferate the acceptance of HEVs, PHEVs, and FCVs in the market. The desired end result is a technically and commercially verified integrated ETS (Electric Traction System) product design that can be manufactured and distributed through a broad network of competitive suppliers to all auto manufacturers. The objectives of this FCVT program are to develop advanced technologies for an integrated ETS capable of 55kW peak power for 18 seconds and 30kW of continuous power.

Wide-load-range resonant converter supplying the SAE J-1773 electric vehicle inductive charging interface

Journal Article Hayes, J; Egan, M; Murphy, J; ... - IEEE Transactions on Industry Applications (Institute of Electrical and Electronics Engineers)

The recommended practice for electric vehicle battery charging using inductive coupling (SAE J-1773), published in January 1995 by the Society of Automotive Engineers, Inc., outlines values and tolerances for critical vehicle inlet parameters which must be considered when selecting a coupler driving topology. The inductive coupling vehicle inlet contains a significant discrete capacitive component in addition to low magnetizing and high leakage inductances. Driving the vehicle interface with a variable-frequency series-resonant converter results in a four-element topology with many desirable features: unity transformer turns ratio; buck/boost voltage gain; current-source operation; monotonic power transfer characteristic over a wide load range; throttlingmore »« less

Charge monitor for electric battery

Patent Kremer, M

An electric battery, such as that of an automotive vehicle, is continuously tested for its state of charge by a bridge circuit in parallel with a voltage stabilizer such as a Zener diode which forms part of a voltage divider connected across the battery terminals, the other part of that divider being a resistance circuit. The bridge circuit has an output diagonal with one corner connected to the battery terminal which is tied to the resistance circuit so that a reduction of battery voltage unbalances the bridge in one sense, a compensatory change in the opposite sense being brougnt aboutmore »« less
Closed-loop optimization of fast-charging protocols for batteries with machine learning

Journal Article Attia, Peter; Grover, Aditya; Jin, Norman; ... - Nature (London)

Simultaneously optimizing many design parameters in time-consuming experiments causes bottlenecks in a broad range of scientific and engineering disciplines. One such example is process and control optimization for lithium-ion batteries during materials selection, cell manufacturing and operation. A typical objective is to maximize battery lifetime; however, conducting even a single experiment to evaluate lifetime can take months to years. Furthermore, both large parameter spaces and high sampling variability necessitate a large number of experiments. As such, the key challenge is to reduce both the number and the duration of the experiments required. Here we develop and demonstrate a machine learningmore »« less
