This whitepaper describes the shift toward integrating multiple high-voltage EV functions—such as battery management, onboard charging, DC-to-DC conversion and power distribution—into a single system-level solution. Traditional architectures with separate control units increase cost, weight and complexity, while integrated power electronics reduce packaging space, improve efficiency and streamline system design. Software plays a critical role in managing these systems, requiring high safety standards, real-time control and over-the-air update capability. The result is a more compact, efficient and intelligent power architecture that supports higher performance, improved reliability and advanced EV capabilities.
