Abstract
Military vehicles carry out defence and training functions; however, they also participate extensively in military operations apart from war, such as supporting citizens in emergency situations. Nonetheless, they continue to contribute to pollution, and carbon emissions in Chile have doubled in recent years. Thus, this study seeks a partial solution to this problem, extending the useful life of an archetypal military vehicle, i.e. AIL Storm internal combustion engine vehicle (ICEV), 4.0L gasoline, through its conversion into an electric vehicle (EV) using lithium-ion batteries. AIL Storm ICE emissions are compared with an equivalent EV conversion prototype, analysing the CO2 emissions of the EV charged from the Chilean electricity grid or from a solar photovoltaic charging station, taking advantage of the high levels of solar radiation in Chile. This studied model obtains a travel cost of 0.04USD/km in the “electric grid charge mode” and 0.02USD/km in the “Solar power station charge mode”, affecting the environment with 155kgCO2 emissions per year of use. In the future, technologies to manufacture or assemble lithium batteries must be developed in the Chilean market. Given the availability of this mineral in Chile, this step would reduce costs and make electric mobility more attractive and affordable.
Highlights
Energy, in the form of mechanical power, is essential in vehicle mobility
Archetype vehicle description Among the large variety of military vehicles, the AIL Storm M240 is chosen as a representative vehicle for the purpose of the study, because such a vehicle has been in use since 1995, and considering its expected useful life of 25 years, the entire fleet from this generation will soon need to be retired from service
It is observed that the cost per kilometre of electric vehicle (EV) AIL Storm is cheaper than ICV AIL Storm; from the economic and environmental point of view, it is convenient to use an EV versus a conventional internal combustion engines (ICE) vehicle
Summary
In the form of mechanical power, is essential in vehicle mobility. Transport largely use internal combustion engines (ICE) based on fossil fuels (gasoline, diesel oil, natural gas) to generate the required mechanical power. The main inconvenient of ICE is the emission into the atmosphere of harmful products, such as carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO2) and particulate matter (PM), as direct residual products of the combustion of fossil fuels.
