چکیده :

The growing demand for electric vehicles (EVs) has fueled the need to upgrade cutting-edge technology, performance, and range. This has driven research toward higher voltage architectures. Transitioning the DC link voltage from 400V to 800V presents significant advantages, such as faster charging times, improved powertrain efficiency, and potential reductions in cable size and weight, which can lead to enhanced overall vehicle performance. However, this shift also introduces technical challenges, including the need for redesigned components, greater financial outlay, electromagnetic interference, and compatibility. This paper provides a comprehensive analysis of the 400V-to-800V transition in EVs, evaluating the technical trade-offs and performance benefits. We begin by outlining the general architecture of EV systems, followed by a review of pioneering companies leading advancements in high-voltage EV technologies. Key challenges associated with high-voltage implementation are then discussed, focusing on safety, reliability, and system integration. Through this study, we offer insights into the practical implications and future potential of adopting 800V systems in electric vehicles.
