“…Similarly to what happens for the pollutant emissions, it is possible to modify the problem definition to include in the cost function the reduction of battery life during the driving cycle [20]. If the battery temperature variation is neglected (assuming perfect cooling), then the problem can be formulated once again as in the standard case, only modifying the cost function.…”

Résumé -Questions ouvertes sur la supervision énergétique des véhicules hybrides électriques : une approche unifiée par la théorie de la commande optimale -Cet article a pour objet la gestion optimale de l'énergie pour un système de propulsion hybride. Le problème traditionnel de répartition de la puissance est modifié avec des nouveaux objectifs d'optimisation et des nouvelles contraintes. Les nouveaux objectifs d'optimisation incluent les émissions de polluants et le vieillissement de la batterie. Les contraintes sont modifiées pour prendre en compte des batteries à recharge externe (hybrides plug-in). De plus, des problèmes spécifiques sont traités avec une modélisation plus détaillée, qui comprend : les dynamiques thermiques du moteur à combustion interne et du catalyseur, pour prendre en compte les effets du démarrage à froid ; les dynamiques thermiques des systèmes de récupération de la chaleur à l'échappement ; la température de la batterie, qui a un effet sur ses performances et son vieillissement. L'article montre comment tous ces problèmes peuvent être traités de façon cohé-rente avec une extension de l'approche ECMS (Equivalent Consumption Minimization Strategy, ou stratégie de minimisation de la consommation équivalente), qui est une implémentation du principe du minimum de Pontryagin formulé dans la théorie de la commande optimale. Des définitions étendues de la fonction Hamiltonienne et des multiplicateurs de Lagrange sont présentées, ainsi que les résultats des optimisations illustrant les bénéfices de cette approche unifiée et ses limites dans l'implémentation en ligne.

Energy Storage Systems (ESS) are o en proposed to mitigate the uctuations of renewable power sources like wind turbines. In such a context, the main objective for the ESS control (its energy management) is to maximize the performance of the mitigation scheme.However, most ESS, and electrochemical ba eries in particular, can only perform a limited number of charge/discharge cycles over their lifetime. is limitation is rarely taken into account in the optimization of the energy management, because of the lack of an appropriate formalization of cycling aging.We present a method to explicitly embed a limitation of cycling aging, as a constraint, in the control optimization. We model cycling aging with the usual "exchanged energy" counting method. We demonstrate the e ectiveness of our aging-constrained energy management using a publicly available wind power time series. Day-ahead forecast error is minimized while keeping storage cycling just under an acceptable target level.

Optimal Design of Power-Split HEVs Based on Total Cost of Ownership and CO2 Emission Minimization

et al. 2018

An optimal design toolbox for hybrid electric vehicles has been developed and applied to three different vehicle segments (a compact vehicle, a small SUV and a medium-size SUV) for two separate power-split hybrid layouts, both equipped with a diesel engine. One layout features a (3gTR) whereas the other lacks of the additional 3-gear transmission. The toolbox combines the optimization of the vehicle design to that of the control strategy and is based on the minimization of the total cost of ownership (TCO) over the vehicle lifetime. The tool still retains the capability of complying with different performance and emission constraints. The identified optimal designs have proved to lead to a reduction of the CO 2 emissions by 50 to 55% and to a reduction of the TCO by 9 to 10% if compared to the conventional vehicle. Such results held for all classes of vehicle. A cost-benefit analysis and a break-even analysis have also been carried out. A mileage of 20,000 km/year over an urban driving scenario has turned out to possibly allow the driver to break even in about four years for the SUVs and in about six years for the compact vehicle. Finally, a linear correlation between the TCO and the specifications of the design components has been detected with a mean percentage error of about 0.1%. Such a correlation can be very helpful for vehicle design tasks.
