Design methodology of an electric vehicle hybrid energy storage unit for improved energy efficiency
Abstract
This work proposes a design methodology that allows designing the energy storage unit of an electric vehicle in order to minimize the required energy and the resulting losses. A simple analytical model of the vehicle losses is derived. Driving conditions and solar production scenarios are obtained from stochastic processes; they are employed to generate a number of vehicle power profiles. Candidate supercapacitor arrangements are classified in terms of losses and energy capacity, leading to the associated Pareto minimum.

Electric vehicle battery
An electric vehicle battery (EVB, also known as a traction battery) is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). Electric vehicle batteries differ from starting, lighting, and ignition (SLI) batteries, as they are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density. Smaller, lighter batteries are desirable because they reduce the weight of the vehicle and therefore improve its performance.
Hybrid electric vehicle
A hybrid electric vehicle (HEV) is a type of hybrid vehicle that combines a conventional internal combustion engine (ICE) system with an electric propulsion system (hybrid vehicle drivetrain). The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance. There is a variety of HEV types and the degree to which each function as an electric vehicle (EV) also varies.
Energy storage
Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms.
