A Review of Critical State Joint Estimation Methods of Lithium-Ion Batteries in Electric Vehicles
2022
Author(s): Wen C, Xu Q, Chen M, Xiao Z, Wen J, Luo Y, Zhao X, Liang Y, Liang K.
Battery state of charge (SOC), state of health (SOH), and state of power (SOP) are decisive factors that influence the energy-management system (EMS) performance of electric vehicles. However, the accurate estimation of SOC, SOH, and SOP remains challenging due to the high nonlinearity of the battery dynamic characteristics and the strong coupling among the states
Technical Feasibility of Heavy-Duty Battery-Electric Trucks for Urban and Regional Delivery in Germany—A Real-World Case Study
2022
Author(s): Link S, Plötz P.
This case study aims to assess the technical feasibility of urban and regional delivery in Germany based on real-world and per-vehicle operational data that feed into an energy simulation with Monte-Carlo modeling.
Where to Charge Electric Trucks in Europe—Modelling a Charging Infrastructure Network
2022
Author(s): Speth D, Sauter V, Plötz P.
The European Union plans to build a fast charging network for trucks to decarbonize road freight transport. This paper presents two scenarios covering European highways with charging stations at regular intervals every 50 or 100 km along the most important highways.
Potential of Load Shifting in a Parking Garage with Electric Vehicle Chargers, Local Energy Production and Storage
2022
Author(s): Castellucci V, Wallberg A, Flygare C.
This article provides a case study based on a real-world parking garage with a smart grid infrastructure called Dansmästaren. The analysis shows how renewable energy sources, energy storage technologies, and smart charging of electric vehicles can smooth out the load curve of the parking garage and relieve the electric grid during peak hours.
Effects of the Incorporation of Electric Vehicles on Protection Coordination in Microgrids
2022
Author(s): Saldarriaga-Zuluaga SD, López-Lezama JM, Zuluaga Ríos CD, Villa Jaramillo A.
Electric vehicles (EVs) would connect to the grid using clean, renewable electricity; however, the interconnection between EVs and the grid brings about new challenges for traditional power systems. Plug-in hybrid and plug-in EVs have become more prevalent in the system; therefore, their impacts and benefits are also of concern.
Life-Cycle Analysis of Greenhouse Gas Emissions of Hydrogen, and Recommendations for China
2022
Author(s): Yuanrong Z, Zhen Z, Li Y
This study estimates the carbon intensity of eleven hydrogen pathways in China and compares them to the eligibility requirements for the fuel cell vehicle (FCV) pilot city program in China that promotes the adoption of FCVs and the use of hydrogen fuel.
Recommendations for the Next Generation of China’s Heavy-Duty Vehicle Emission Standard Based on Testing of China VI Vehicles
2022
Author(s): Niu T, Rodríguez F
This study analyzes on-road and laboratory testing of two trucks certified under the China VI-b emission standard and examines the gaps between China VI and the latest developments in European standards.
Integrating Refrigerants with Low Global Warming Potential into India’s Light Vehicle Fuel Efficiency Standards
2022
Author(s): Deo A, German J, Callahan J
This study analyzes potential reductions in greenhouse gas emissions from using alternative refrigerants with low global warming potential and more efficient air conditioning systems in vehicles in India.
No Fleet Left Behind: Barriers and Opportunities for Small Fleet Zero-Emission Trucking
2022
Author(s): Brito J
This paper evaluates the zero-emission truck market and suggests actions to overcome barriers for adoption for small fleets. Failing to support small fleets would put them at risk of being unable to transition to zero-emission vehicles, in turn putting jurisdictions at risk of failing to achieve emissions reduction targets.
Assessment of Light-Duty Electric Vehicle Costs and Consumer Benefits in the United States in the 2022–2035 Time Frame
2022
Author(s): Slowik P, Isenstadt A, Pierce L, Searle S
The study analyzes component-level costs to evaluate electric vehicle price parity with conventional vehicles.
