“…The charging of EVs has consequences for the distribution, transmission and generation of electricity 41 . For example, uncontrolled charging has been shown to increase peak demand and cause transformer overloading 5 , force early replacement of equipment 7 , overload transmission lines 28 , worsen power quality 4,6 or require substation upgrades 42 .…”

Electric vehicles will contribute to emissions reductions in the United States, but their charging may challenge electricity grid operations. We present a data-driven, realistic model of charging demand that captures the diverse charging behaviours of future adopters in the US Western Interconnection. We study charging control and infrastructure build-out as critical factors shaping charging load and evaluate grid impact under rapid electric vehicle adoption with a detailed economic dispatch model of 2035 generation. We find that peak net electricity demand increases by up to 25% with forecast adoption and by 50% in a stress test with full electrification. Locally optimized controls and high home charging can strain the grid. Shifting instead to uncontrolled, daytime charging can reduce storage requirements, excess non-fossil fuel generation, ramping and emissions. Our results urge policymakers to reflect generation-level impacts in utility rates and deploy charging infrastructure that promotes a shift from home to daytime charging.

“…In addition to agricultural load, the electrification of other sectors has the potential to offer opportunities for load shifting, which could help to ease the generation and storage capacity requirements for future decades. 8 For example, many studies envision using an electrified transport fleet to help balance the grid (Anwar et al 2022). And industrial processes, while potentially limited in their direct electrification potential, could still benefit from coordination with the grid.…”

“…An example of a narrower focus electrification question, although with broad applicability and extensively researched, is how to manage the charging of a growing electric vehicle fleet. A literature review of this topic Anwar et al (2022) shows the extent to which this question can be framed, spanning multiple control strategies, several potential grid services from electric vehicles, communications and controls considerations, power flow deviations, cost and benefit analyses, reliability impacts, etc. Figure 4 shows the various studies, methods, and modeling perspectives represented by the set of studies considered, exemplifying that this somewhat narrow focus-how to manage charging of a vehicle-has broad impacts that will need to be understood by many in the power sector.…”

“…Nowadays, purely electric transmission is becoming increasingly popular in the automotive field [1,2]. The main advantage of this type of transmission is to cut down local pollutant emission [3][4][5][6], so as to improve air quality of urban centres and, hence, help in the reduction of global pollution.…”

Smart Design: Application of an Automatic New Methodology for the Energy Assessment and Redesign of Hybrid Electric Vehicle Mechanical Components

This work aimed to develop an automatic new methodology based on establishing if a mechanical component, designed for a conventional propulsion system, is also suitable for hybrid electric propulsion. Change in propulsion system leads to different power delivery and vehicle dynamics, which will be reflected in different load conditions acting on the mechanical components. It has been shown that a workflow based on numerical simulations and experimental tests represents a valid approach for the evaluation of the cumulative fatigue damage of a mechanical component. In this work, the front half-shaft of a road car was analyzed. Starting from the acquisition of a speed profile and the definition of a reference vehicle, in terms of geometry and transmission, a numerical model, based on longitudinal vehicle dynamics, was developed for both conventional and hybrid electric transmission. After the validation of the model, the cumulative fatigue damage of the front half-shaft was evaluated. The new design methodology is agile and light; it has been dubbed “Smart Design”. The results show that changing propulsion led to greater fatigue damage, reducing the fatigue life component by 90%. Hence, it is necessary to redesign the mechanical component to make it also suitable for hybrid electric propulsion.
