Lithium-ion battery is the core of new plug-in hybrid-electrical vehicles (PHEV) as well as considered in many 2nd generation hybrid electric vehicles (HEV). In most cases the lithium-ion battery performance plays an important role for the energy management of these vehicles as high-rate transient power source cycling around a relatively fixed state of(More)
Derived from the Pseudo Two-Dimensional mathematical structure, a simplified electrochemical and thermal model of LiFePO4-graphite based Li-ion batteries is developed in this paper. Embedding the porous electrode theory, this model integrates the main design parameters of Li-ion systems and its partial differential equations mathematical structure makes it(More)
Lithium-ion batteries are the core of new plug-in hybrid-electrical vehicles (PHEV) as well as considered in many 2nd generation hybrid electric vehicles (HEV). In most cases the lithium-ion battery performances play an important role in the vehicle energy management. As consequence, battery modeling is one of the most important tasks for hybrid and(More)
This work addresses the problem of finding energy-optimal velocity profiles for a vehicle in an urban traffic network. Assuming communication between infrastructure and vehicles (I2V) and a complete knowledge of the upcoming traffic lights timings, a preliminary velocity pruning algorithm is proposed in order to identify the feasible region a vehicle may(More)
In this work an experimental parameter identification and validation for an electrochemical lithium-ion battery model is illustrated. The model was presented in [2] where, aimed at estimating the battery State Of Charge (SOC), the model was also averaged and an extended Kalman filter based on the average model was designed. The identification procedure is(More)
In this paper an averaged electrochemical lithiumion battery model, presented and discussed in [2] and [3], is identified and validated through experimental data by a 10 Ah li-ion battery pack, during charge and discharge experiments. The model is based on an approximation relationship between the averaged Butler-Volmer current and the average solid(More)
The power management of an hybrid system composed of a fuel cell, a battery and a DC/DC power converter is developed. A decoupled control strategy is proposed, aimed at balancing the power flow between the stack and the battery and avoiding electrochemical damage due to low oxygen concentration in the fuel cell cathode. The controller is composed of two(More)
This work presents experimental tests of a vehicle localization system. Based on data collected by a global positioning system (GPS), an odometer and a gyrometer, to measure respectively vehicle position, vehicle velocity and yaw velocity, an estimation strategy of the vehicle cover distance is designed. A prototype is then realized in order to test the(More)
In this paper, an isothermal physics-based aging model from the literature is modified and extended to simulate both capacity and power fade of a commercial LiFePO4-graphite Li-ion battery. Compared to the isothermal reference, the mechanism of porosity modification due to the Solid Electrolyte Interphase (SEI) film growth at the negative electrode is(More)
This paper presents a numerical calculation of the evolution of the spatially-resolved solid concentration in the two electrodes of a lithium-ion cell. The microscopic solid concentration is driven by the macroscopic Butler Volmer current density distribution which is consequently driven by the applied current through the boundary conditions. The resulting,(More)
