An Assessment of Electric Vehicles and Vehicle to Grid Operations for Residential Microgrids
2022
Author(s): O'Neill D, Yildiz B, Bilbao JI
This paper evaluates the annual operation and benefits of EVs and V2G in a microgrid environment and demonstrates different modes of operation. Guided by the gaps identified in the literature, one of the main contributions of this research is to uncover the impact of EV charging scenarios on the V2G operations.
Driving demand: assessing the impacts and opportunities of the electric vehicle revolution on cobalt and lithium raw material production and trade
2021
Author(s): Bridle R, Bellmann C, Loyola V, Mostafa M, Moerenhout T
This report assesses the impact and opportunities for developing countries of the boom in demand for raw materials entering into the production of electric vehicle batteries. In particular, it describes how trade policy could play an important role in helping them capture value from this expansion while managing the risks of overinvestment.
Experimental Driving Performance Evaluation of Battery-Powered Medium and Heavy Duty All-Electric Vehicles
2022
Author(s): Sato S, Jiang YJ, Russell RL, Miller JW, Karavalakis G, Durbin TD, Johnson KC
This study evaluated and quantified the energy consumption rates and energy regeneration rates for three heavy-duty battery electric vehicles (a step van, a yard tractor, and a class 8 truck) using driving cycle tests with a heavy-duty vehicle chassis dynamometer.
Hitting the EV inflection point: electric vehicle price parity and phasing out combustion vehicle sales in Europe
2021
Author(s): Bloomberg Finance L.P
Electric vehicle sales are rising fast in Europe and a growing number of governments have set targets for phasing out new internal combustion vehicle sales. A fundamental input in deciding the feasibility of such policies is how quickly battery electric vehicles can reach price parity with their internal combustion counterparts. Further improvements in lithium-ion batteries will be critical and manufacturing strategy will also play a role. This report shows trajectories of cost developments for the production of battery electric vehicles and internal combustion engine vehicles, and the implications for the adoption of electric vehicles in Europe.

2022
Author(s): Perčić M, Frković L, Pukšec T, Ćosić B, Li OL, Vladimir N
The aim of this research is to compare the conventional power system with a diesel engine and alternative power system with a selected battery to identify convenient technology for zero-emission shipping according to the environmental and economic criteria.
Optimizing the Electrification of Roads With Charge-While-Drive Technology
2022
Author(s): Schwerdfeger S, Bock S, Boysen N, Briskorn D
This paper provides a detailed modeling approach based on continuous variables to minimize the installation costs for electrified highway kilometers while providing sufficient energy for a given set of representative tours of electric vehicles.
Solar energy–based EV charging: a pilot and techno-economic study
2021
Author(s): Center for Study of Science, Technology and Policy (CSTEP)
The report outlines an intelligent bi-directional converter (PCU) that interfaces with SRTPV and battery systems (with DC coupling) to manage the energy flow with EV chargers and the grid. The prioritisation of solar energy for local consumption before feeding it to the grid, deployment of a novel charging algorithm where the EV charging load is made to follow and the solar energy generation profile. Such a method reduces the need for costly battery energy.
Exploring the Characteristics of Technological Knowledge Interaction Dynamics in the Field of Solid-State Batteries: A Patent-Based Approach
2022
Author(s): Block A, Song CH
This study provides a novel patent-based analysis framework for identifying the latent knowledge structure of technological domains by adopting dynamic perspectives. It uses patent data collected between 2010 and 2018 to systematically examine and visualize promising knowledge interactions that could foster the advancement of solid-state battery technology.
Data-Driven Battery State of Health Estimation Based on Random Partial Charging Data
2022
Author(s): Deng Z, Hu X, Li P, Lin X, Bian X
The rapid development of battery technology has promoted the deployment of electric vehicles (EVs). To ensure the healthy and sustainable development of EVs, it is urgent to solve the problems of battery safety monitoring, residual value assessment, and predictive maintenance, which heavily depends on the accurate state-of-health (SOH) estimation of batteries.
