| Outline of Research at the Start |
EVs are being strongly developed worldwide to gradually substitute for gasoline
vehicles as an approach to combat the severe climate changes caused by greenhouse gas emissions. Technologies for EVs unfortunately have not been mature as that for gasoline alternates, hence requiring much more effort to increase their energy efficiency, economy, and charging convenience for users. This project exploits the repetition on the daily driving of a large class of EV users to develop novel iterative learning control methods for the better electricity and thermal control and management of EVs.

| Outline of Annual Research Achievements |
In the FY2023, a novel iterative learning control (ILC) algorithm based on a quadratic performance index with iteration-varying weighting matrices was derived. As a result, this ILC algorithm has iteration-varying learning gains. The superior performances of this algorithm for tracking iteration-varying references compared to that by conventional ILC laws with iteration-invariant learning gains were reported. This algorithm was then applied for the tracking of daily-varying state-of-charge profiles of electric vehicle batteries, whose results showed great potentials.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The derived results so far are matched with the proposed timeline.

| Strategy for Future Research Activity |
In the next works, more complicated electrothermal models of Li-ion batteries will be taken into account in the design of iterative learning controllers. Additionally, the problem of employing electric vehicle Li-ion battery packs to provide ancillary services will be investigated. In the simulations, realistic and publicly available data will be utilized.
