18 ANSYS ADVANTAGE ISSUE 2 | 2017 Leading the Electric Vehicle Charge The battery management system plays a critical role in today’s electric vehicles: It monitors the state of the battery, manages its operation to optimize vehicle performance and battery life, and ensures the safety of occupants. Researchers at National Electric Vehicles Sweden (NEVS) who are developing the BMS for their next-...

Nowadays, transportation is one of the main air pollution sources and has a significant impact on human health and environmental quality. The electric vehicle is a zero emission vehicle powered by an electric motor with power from an electricity source, usually a battery or super-capacitor. However, monitoring and managing the recharging of electric vehicles represents a challenge. The purpose ...

Purpose: On pursue of economic revenue, the second life of electric vehicle batteries is closer to reality. Common electric vehicles reach the end of life when their batteries loss between a 20 or 30% of its capacity. However, battery technology is evolving fast and the next generation of electric vehicles will have between 300 and 400 km range. This study analyzes different End of Life scenari...

State of health (SOH) of batteries in electric and hybrid vehicles can be observed using some battery parameters. Based on a resistanceecapacitance circuit model of the battery and data obtained from abundant experiments, it was observed that the diffusion capacitance shows great correlation with SOH of a lithium-ion battery. However, accurate measurement of this diffusion capacitance in real t...

Most of the present day electric scooters are equipped with a voltage-driven DC motor powered by four 12-volt leadacid batteries and a hand-lever accelerator operated by the rider to control their speed. Because of the nonlinear battery discharge characteristics and different driving behaviors of riders, it is not easy to tell how much electric power remaining in the battery and how far the ele...

With respect to the limitations of fossil energy resources, different types of electric vehicles (EVs) are developed as suitable alternatives. Lithium-ion (Li-ion) battery cells play an extremely important role in EVs due to their unique features. But they need a thermal management system (TMS) to maintain their surface temperature uniformity and avoid them from thermal runaways. In the current...

As part of the ongoing effort to be independent of petroleum resources and to be free from pollutant emission issues, various electric vehicles have been developed and tested through their integration with real world systems. In the current paper, yet another application specific EV for public transportation, an electric bus, is introduced and explained with results from the pilot test program ...

The driving range is an important issue of electric car manufacturers and electric vehicle fleet operators, and it directly influences the cost, operation and customer satisfaction. The estimation of Battery performance which has a significant impact on the driving range is an immature technique, however ARTC (Automotive Research & Testing Center) proposed to estimate parameters including energ...

Electric vehicles are considered as technology which can significantly reduce the problems related to road transport such as increasing GHG emissions, air pollutions and energy import dependency. The core objective of this paper is to analyze the current energetic, ecological and economic characteristics of different types of electric vehicles. The major conclusions of this analysis are: The hi...
