“…The research presented within this study extends that published in [17] and provides two key contributions to the body of literature within this field. Primarily, an ageing and characterisation study is conducted to investigate the possible effects and consequences of continuous HP cycling on the electrical characteristics of a 53 Ah pouch cell of G-NMC chemistry (Graphite -Lithium-Nickel-Manganese-Cobalt-Oxide).…”

Key subsystem parameters, such as power and torque ratings, and subsystem efficiencies are fully defined within [17].

“…Previously established testing procedures for cell and battery systems are insufficient to evaluate the suitability of LIB cells (in terms of: cycle life, thermal behaviour, and progression of degradation) for use in evaluation battery technology for HP-EVs [16].The authors' previous work [17] demonstrated significant differences between the "Dynamic discharge profile A for BEV cycle test" as described in the IEC 62660-1 standard, and a newly developed dutycycle representing HP scenarios. Whilst the IEC standard serves to represent a cell profile for BEVs operating on the road, the high-performance duty cycle (HP-C), in contrast, is representative of an HP-EV driving on a race circuit and was derived from a database of race circuit driving simulations.…”

A B S T R A C TThe long-term behaviour of lithium ion batteries in high-performance (HP) electric vehicle (EV) applications is not well understood due to a lack of suitable testing cycles and experimental data. As such a generic HP duty cycle (HP-C), representing driving on a race track is validated, and six NMC graphite cells are characterised with respect to cycle-life. To enable a comparison between the HP-EV environment and conventional road driving, two test groups of cells are subject to an experimental evaluation over 200 duty cycles that includes a representative HP-C and a standard duty cycle from the IEC 62660-1 standard (IECC). After testing, both test groups display increased energy capacity, increased pure Ohmic resistance, lower charge transfer resistance an extended OCV operating window. The changes are more pronounced for cells subject to the HP-C. Based on capacity tests, Electrochemical Impedance Spectroscopy (EIS), pseudo-OCV tests, and Pulse Multisine Characterisation, it is concluded that the changes in cell characteristics are most likely caused by cracking of the electrode material caused by high electrical current pulses. With continued cycling, cells cycled with the HP-C are expected to show degradation at an increased rate due to raised temperatures, and more pronounced electrode cracking.

Owing to the higher thermal efficiency and durability, diesel engines have emerged as a major player in automotive sector but exhaust emissions from engines pose a serious threat to environment and human health. Toxicity levels of exhaust emissions can be reduced by application of pretreatment and posttreatment techniques. Introduction of electric vehicles is considered as the best possible alternative for reducing automotive pollution levels. Requirement for charging infrastructure is one of the major parameters affecting the social acceptance of electric vehicles. Deployment of electric vehicles in countries, which relies primarily on fossil fuels for electricity generation, will only shift the emission threat from vehicle operation phase to energy generation phase. In this article a detailed study has been conducted on the posttreatment emission control strategies for diesel engines and conversion efficiency of platinum based diesel oxidation catalysis system has been investigated with experimental inference. Fossil fuel based energy sources have more than 70% share in electricity generation of India. Additionally, a feasibility study on the deployment of solar based electric vehicle charging stations on the roof of existing fuel stations in Dehradun city, India has been conducted. The results of study showed that the proposed PV system at 26 fuel stations have total energy generation capacity of 1.9 GWh. This indicates that the deployment of solar based charging stations will be an effective method for improving the social acceptance of battery electric vehicles and will also enhance the share of renewable energy sources for power generation.

To achieve accurate prediction of the nonlinear behavior of lithium‐ion battery, parameters of the lithium‐ion battery model play a key role for dynamic performance, hence the parameters of the investigated battery model have been estimated. In this work, the electrical equivalent circuit (ECM) models have been used to simulate INR18650‐20R lithium‐ion battery response at 0°C, 25°C, and 45°C, respectively. The ECM model parameters are estimated using incremental open‐circuit voltage (OCV) profile and Trust‐Region Reflective algorithm by the Non‐Linear Least Squares method. The estimated parameters of the ECM model experimentally validated using independent dynamic current profiles including Dynamic Stress Test (DST), Federal urban driving schedule (FUDS), Beijing Dynamic Stress test (BJDST), and US06 at 0°C, 25°C, and 45°C, respectively. Coulomb‐counting based algorithms are implemented for model‐based online SoC estimation. The investigated ECM model with three parallel RC branches exhibits accuracy below 1.8% for different temperature levels and seems suitable to capture the nonlinear dynamics of lithium‐ion batteries for EV application. It is confirmed that the errors resulting from the investigated ECM model are significantly reduced comparatively existing published models.
