“…The scheme adapted for modelling a representative fuel cell vehicle for evaluating the fuel consumption for different drive cycle pattern for Mexico city is shown in Figure 1. The current work is based on Toyota MIRAI fuel cell vehicle, since sufficient amount of data and experimental results are available for validating the model Lohse-Busch et al [38]. The work assumes that the control logic for estimating torque and power required from fuel cell follows the control logic used in Toyota Prius Hybrid Electric Vehicle (Prius HEV) with regenerative braking system.…”

“…Fuel cell model in GT-Suite [GT-Suite, 2018] estimates the open circuit voltage based on Gibbs free energy of formation and estimates activation loss, mass transport loss, Ohmic loss for the given operating temperature to determine the voltage generated by the fuel cell for a given operating temperature. The input parameters required for modelling and the overall specification of the hydrogen fuel cell used in the model were obtained from Lohse-Busch et al [38]. The major components and systems used for modelling the fuel cell in GT-Suite is shown in Figure 3.…”

“…The total energy required for following the drive cycle consists of energy available from the energy storage system, energy recovered from regenerative system and energy required for overcoming the losses in the mechanical and electrical sub-systems. The total amount of fuel consumed by the fuel cell for the entire drive cycle in kg/100 km was obtained from the model and compared against the experimental data obtained from Argonne National Laboratory data sets Lohse-Busch et al [38]. Two different drive cycles were chosen for the validation purpose based on the characteristics of the drive cycle.…”

The search for alternative fuel for transport vehicles and also replacement of internal combustion engines in order to reduce the harmful emissions have been forcing the vehicle manufacturers to innovate new technology solutions for meeting the stringent legislative targets. Mexico's commitment for de-carbonisation of transport sector and meeting the environmental goals is shaping it especially, and with this, it favours the move towards electrification of the vehicles. The aim of the present work is to numerically evaluate the possibility of replacing the IC engine in the existing hybrid vehicles with the Hydrogen fuel cell system. This work modelled a Hydrogen fuel cell vehicle based on Toyota MIRAI and validated the fuel economy performance of the vehicle using experimental data. This validated model was used to estimate the fuel economy for real-world drive cycles generated in 2019 from Mexico City. It considered three different drive cycles representing real-world driving in the Metropolitan Area of the Valley of Mexico. This study estimated the amount of reduction in CO2 and other pollutants for the year 2020, and 2030 and 2040 if the IC engine in the electric hybrid vehicles is replaced with the Hydrogen fuel cell. The study also estimated the amount of Hydrogen fuel required for replacing the IC engines with the Hydrogen fuel cell for moving towards electrification of light duty vehicles.

“…The FC is a unidirectional power source and so requires secondary power sources, such as batteries and supercapacitors (SCAPs), to absorb regenerative braking energy [5]. The dynamic response of an FC has, until recently, been regarded as slow which has resulted in these secondary power sources providing power to the traction motor during vehicle acceleration to improve the performance of the vehicle [6][7][8].…”

Fuel cell vehicle energy management strategy based on the cost of ownership

This study presents a novel energy management strategy (EMS) which outperforms the published strategies developed for an international technology challenge, IEEE Vehicular Technology Society (VTS) Motor Vehicles Challenge 2017. The objective of the strategy is to minimise the cost of ownership of a low-power (15 kW) fuel cell (FC)-battery electric vehicle. Both the fuel consumption cost and power sources degradation costs are combined to represent the total cost of ownership. The simple adaptive rule-based strategy optimises the FC operation during low-traction power operation and switches to battery charge-sustaining operation for high traction power operation. This minimises fuel consumption and increases the lifetimes of the FC and of the battery. The strategy is then compared with the EMS of the 2015 Toyota Mirai, and the challenge vehicle model is modified to capture the learnings from the Mirai. Finally, a cost-benefit analysis for a plug-in FC vehicle is considered in order to improve FC lifetimes and to reduce costs for short drive cycles.
