“…The EV batteries available at present can consume up to 5-8 h for getting fully charged. This puts in perspective the need for rapid expansion of charging stations to bring the number of charging ports up to at least a decent level (Madhu et al, 2018;Phatak et al, 2020;Preetha Yesheswini et al, 2020;Save et al, 2019). At present, there are, at the most, 500 public charging stations in India (Ganesh, 2019;PTI, 2020a), and the Government of India (GOI), foreseeing the requirement, has established an impressive target of erecting one charging station per 3 km distance in cities and at every 25 km interval on both sides of highways (Research and Markets, 2019).…”

Purpose The purpose of this study is to understand the specific reasons why developed countries could easily start implementing innovative alternative fuel vehicles (e.g. electric vehicles or EVs) while the implementation in developing countries looks so far-fetched, with respect to infrastructure and downstream activities, and suggest the steps that can be taken to effectively address these issues. Design/methodology/approach This research undertakes case study – Tesla (USA), Mahindra and Mahindra (India) and Tata Motors to bring out the problems being faced by manufacturers from developing countries vis-a-vis the developed countries. The consumers’ side has been adequately represented though an in-depth survey. An analysis is also carried out as to how Tesla has accrued competitive leverage by innovating and vertical integration of up as well as downstream systems. Findings EV infrastructure remains grossly inadequate in developing countries like India. Two key areas that remain significantly unexplored are the installation of charging stations at parking lots and at the housing clusters and lack of competitive leverage in the services, processes and other downstream systems due to limited research and development capabilities. The performance metrics of domestic EVs lag those of conventional vehicles as well as foreign competitors like Tesla. Range anxiety is ranked as number one in the major concerns among the potential mass buyers of electric vehicles in India. Originality/value The value of the paper lies in an in-depth analysis of the relationship between horizontal and vertical perspectives as well as the impact of the product eco-system innovation on both the upstream as well as downstream nodes in the supply chain. Whereas the consumer attitudes and perspectives on e-mobility are inferred from a survey, the impact analysis matrix is used for analyzing the competitive leverage of Tesla through several features in the upstream, downstream and servitization.

The surge in Electric Vehicle (EV) adoption has intensified energy demand, prompting the integration of Solar Photovoltaic (S-PV) systems for optimization. To address the challenge of fluctuating load demand with seasonal changes, a novel approach is proposed. This system combines Laguerre Polynomial-based Ramp Rate Method (LP-RRM) to smooth DC power from S-PV, Generalized Space Vector Modulation-based Switching Regulators (GSVM-SR) to tackle grid interruptions, and Rosenbrock Function-based Sea-Horse Optimization (RF-SHO) for optimal Charging System (CS) selection. Pre-processing the dataset identifies seasons and extracts features, which are fed into Joint Fusion Layer – Bidirectional Long Short Term Memory (JFL-BiLSTM) for load demand forecasting. The chosen CS is determined from a constructed graph based on user requests. The proposed technique effectively mitigates blackout risks and facilitates efficient EV charging operations, yielding promising results according to simulation outcomes.

SummaryThe use of electric vehicles (EVs) has gained traction in recent years. With the widespread use of EVs in the future, the waiting time before charging will be high due to the use of slow chargers in developing countries. This work proposes a novel DC‐DC converter based on an isolated single‐ended primary inductor converter (SEPIC) and isolated Ćuk converter to enable simultaneous charging of batteries of low‐ and medium‐power EVs. The proposed converter operates without spikes in input and output currents, even during a sudden source disturbance. It can charge one battery at the output voltage level and simultaneously charge two batteries at half the output voltage. Simulation results for open‐loop and closed‐loop operations are provided to validate the converter operation and the simplicity of control. The proposed converter operation has been experimentally validated using a scaled‐down prototype by charging one 48 V lithium‐ion battery and then simultaneously charging two 24 V lithium‐ion batteries. The converter's response is provided to present the novelty and advantages of the proposed converter. The proposed converter uses fewer switches, diodes, inductors, and capacitors. The size of the system is reduced due to the high switching frequency operation of SiC devices. A low‐side gate driver is sufficient for driving the MOSFET, and the control is simple. The proposed converter offers a new and simple converter to charge multiple low‐ and medium‐power EV batteries of different ratings simultaneously with a low component count.
