Energetic requirements of heavy duty urban transport hybrid vehicles. Analysis on urban bus and waste collect cases in terms of use and electrification degree

The requirements to reduce pollution from vehicles are increasing and this is most prominent, if possible, in urban areas. The way followed by automotive industry to answer this demand consists on vehicle electrification. To reach the aim of pure electric vehicles is passing through intermediate stages of increasing levels of electrification, that impulse knowledge, experience and development of batteries, converters and the other electric equipment that are in early stages of maturity than the rest. With this view, this article presents a modeling method that allows estimating energy requirements of heavy duty vehicles, assuming different driving cycles and kind of services, with the aim of pre-sizing the electric equipment needed for every case of electrification and range. Specifically urban passenger transport and waste collection cases will be analyzed. The aim is to have a tool that make easier the calculation of weight, volume and cost of the required equipment to cover specific operational needs of an electric vehicle, reducing time and cost of tests. These results allow forming a judgment on how far is interesting going with electrification grade on a specific vehicle and use.
