“…This is particularly true for HEVs as the engine is subject to stop-start phases, and its temperature θ e is not constant. However, several studies [9], [22] and [23] have suggested that the engine temperature could be eliminated from the state space, as it has a negligible influence on the results observed with EMS minimizing fuel consumption (the benefit of including engine temperature in term of fuel consumption is less than 0.5% for the systems studied in [9] and [23]). A theoretical justification of these results, reported in line (b) of Table I, are given in [10] based on regular perturbations in optimal control problems.…”

“…Recent works have aimed at extending such simple optimization problems to consider new cost functions (pollutant emission, battery aging or any combination thereof) and additional state variables (engine, battery and the 3 waycatalyst temperatures) [9], [13], [19], [22]. From engine modeling viewpoint, engine temperature θ e is an important factor [7], influencing both fuel consumption and pollutant emissions.…”

In this paper, we investigate the benefits of considering advanced modeling of engine and after-treatment system (3-way catalyst) in the design of Energy Management System (EMS) for a parallel Hybrid-Electric light-duty Vehicle (HEV) (passenger car with gasoline engine). The evaluation is based on a comparative study of optimal control problems formulated using three distinct levels of model complexity. Starting with a single state dynamics (battery state-of-charge), successively, we consider the engine temperature and the 3-way catalyst temperature, yielding increased complexity. As is shown, the increased complexity brings only little improvement in fuel economy and emissions reduction. We provide quantitative results to assess this observation.

“…[2][3][4] However, most of the current energy management strategies are developed without the consideration of the thermodynamic effects of the combustion engine. 5 Traditionally, operating in cold conditions leads to additional fuel consumption for the combustion engine. 6 Therefore, further potential for improving the energy efficiency lies in considering thermodynamic effects on fuel consumption in the energy management scheme.…”

The process of engine warming-up leads to additional fuel consumption. Energy management strategy considering engine warming-up is expected to further improve the energy economy of hybrid electric vehicles. This study provides a simple yet practical model for engine thermal dynamics. Then, the optimization problem of energy management considering engine warming-up is formulated on the basis of the control-oriented engine thermal dynamics. Thereafter, the optimal solution is derived by using the dynamic programming algorithm. Finally, the proposed engine thermal dynamics and energy management strategy are evaluated through simulation and experiments. Results show that the established engine thermal model effectively captures the main thermal behavior, simulation results reveal a high degree of approximation to experimental results for the engine temperature and fuel consumption, and the energy management strategy with engine temperature can further improve the energy efficiency.
