“…In order to monitor the environmental performance of these vehicles, the U.S. Environmental Protection Agency conducts laboratory tests and publishes environmental protection agency and greenhouse gas scores. In general, higher environmental protection agency and greenhouse gas scores suggest lower tailpipe emissions of carbon dioxide (Mahmoudzadeh Andwari, Pesiridis, Rajoo, Martinez‐Botas, & Esfahanian, ; Messagie, Oliveira, Rangaraju, Forner, & Rivas, ; Palencia, Otsuka, Araki, & Shiga, ). The higher power and storage of the battery allow the HEV to operate without the use of fossil fuels that are generating carbon dioxide emissions.…”

Innovation shock, outsourcing strategy, and environmental performance: The roles of prior green innovation experience and knowledge inheritance

2019

To investigate under what conditions an outsourcing strategy can show superior environmental performance, one stream of scholars has underscored the importance of prior green innovation experience, and another stream of scholars has underscored the importance of the in‐house possession of outsourced component knowledge. However, the empirical findings regarding the positive role of both scholarly streams when studied separately are mixed and sometimes contradictory. This study bridges these two distinct but related streams and suggests that prior green innovation experience and in‐house knowledge regarding outsourced components play a complementary role in enhancing environmental performance. The U.S. hybrid electric vehicle market lends support to the argument of this study. In so doing, this study increases our understanding of the role of prior green innovation experience and outsourced component knowledge on environmental performance while pursuing an outsourcing strategy. This study also provides guidance for managers and policymakers on how to achieve superior environmental performance in outsourcing.

“…Given that the main purpose for HEV technology is to offer environmentally friendly and fuel‐efficient vehicles, the U.S. Environmental Protection Agency (EPA) regularly conducts laboratory tests and publishes greenhouse gas (GHG) emission scores for each vehicle model in order to ensure compliance with California Air Resources Board requirements. A higher GHG score suggests lower tailpipe emissions of carbon dioxide (Mahmoudzadeh Andwari, Pesiridis, Rajoo, Martinez‐Botas, & Esfahanian, ; Messagie, Oliveira, Rangaraju, Forner, & Rivas, ; Palencia, Otsuka, Araki, & Shiga, ). The GHG scoring by the Environmental Protection Agency is ordinal in nature with “10” being the highest and “1” being the lowest scores.…”

The impact of competition on vertical integration: The role of technological niche width

Despite there being numerous studies exploring the relationship between competition and vertical integration, the empirical findings regarding the nature of this relationship are still unclear. The current study suggests that technological niche width mediates the relationship between competition and vertical integration. It also suggests that technological niche width and vertical integration play a complementary role in enhancing firm performance. These arguments have found empirical support in the examination of the U.S. hybrid electric vehicle market from 2008 to 2016. In so doing, this study provides an opportunity to better understand the relationship between competition, vertical integration, and technological niche width. In addition, it explains how firms can effectively manage fierce competition and achieve the goal of superior performance through strategic decisions regarding vertical integration and technological niche width.

“…Hence, the use of electric vehicles (EVs) may be the best solution to reduce global warming [2]. Lightweight battery-powered EVs may afford the greatest CO 2 emission reduction by 87.3% compared with the baseline value of 2050 [3]. Different models for analyzing the energy storage systems of EVs have been proposed recently.…”

Recent research findings indicate that the nonmonotonic consumption of energy from lithium-ion (Li-ion) batteries results in a higher heat generation in electrical energy storage systems. During peak demands, a higher heat generation due to high discharging current increases the temperature from 80 °C to 120 °C, thereby resulting in thermal runaway. To address peak demands, an additional electrical energy storage component, namely supercapacitor (SC), is being investigated by various research groups. This paper provides insights into the capability of SCs in lightweight electric vehicles (EVs) to address peak demands using the worldwide harmonized light-duty driving test cycle (WLTC) driving profile in MATLAB/Simulink at different ambient temperatures. Simulation results indicate that temperature imposes a more prominent effect on Li-ion batteries compared with SCs under peak demand conditions. The effect of the discharging rate limit on the Li-ion battery current is studied. The result shows that SCs can accommodate the peak demands for a low discharging current limit on the battery, thereby reducing heat generation. Electrochemical impedance spectroscopy and cyclic voltammetry are performed on SCs to analyze their thermal performance at different temperatures ranging from 0 °C to 75 °C under different bias values of -0.6, 0, 0.6, and 1 V，respectively. The results indicate a higher specific capacitance of the SC at an optimum operation temperature of 25 °C for the studied bias. This study shows that the hybrid combination of the Li-ion battery and SC for a lightweight EV can address peak demands by reducing thermal stress on the Li-ion battery and increasing the driving range.
