Frequently asked questions
HEV / EV power converters are essential components in hybrid electric vehicles (HEV) and electric vehicles (EV), responsible for managing the flow of electrical energy between the battery, electric motor, and other systems. HEV / EV power converters are advanced test solutions designed to evaluate the performance of power converters, battery management systems (BMS), and DC charging technologies. These tools support testing for onboard chargers (OBC), DC fast chargers, and battery emulation, ensuring efficient energy conversion and reliable operation. Additionally, they enable the validation of vehicle-to-grid (V2G) technology, allowing engineers to test how EVs interact with home energy storage systems and the electrical grid. These solutions are crucial for developing energy-efficient EV architectures and optimizing renewable energy integration through home energy management systems (HEMS).
Yes, HEV / EV power converters support bidirectional power flow, enabling comprehensive testing for vehicle-to-grid (V2G) and home energy management system (HEMS) applications. This capability allows engineers to evaluate how power flows both from the grid to the vehicle for charging (grid-to-vehicle or G2V) and from the vehicle back to the grid or home energy storage system (vehicle-to-grid or V2G). By simulating real-world charging and discharging scenarios, these power converters help validate energy efficiency, battery performance, and grid stability, supporting the development of smart charging infrastructure and renewable energy integration.
Regenerative technology in HEV / EV power converters refers to the ability of test systems to recapture and return absorbed energy back to the grid instead of dissipating it as heat. This energy recovery process significantly reduces energy waste, lowers operational costs, and minimizes the need for extensive cooling systems.
Keysight’s HEV / EV power converters leverage high-efficiency regenerative technology, achieving up to 96% energy efficiency by recycling power during tests of battery management systems (BMS), bidirectional power converters, and vehicle-to-grid (V2G) applications. This makes them both environmentally friendly and cost-effective for extended, high-power testing, supporting the development of sustainable electric vehicle (EV) technologies and renewable energy integration.
Yes, HEV / EV power converters can accurately simulate real-world driving and charging scenarios by emulating dynamic load profiles, fast-charging events, and battery behaviors under various operating conditions. These allow engineers to replicate sudden acceleration, regenerative braking, and fluctuating power demands, testing how power converters, battery management systems (BMS), and onboard chargers (OBC) respond in real time.
Additionally, they support DC fast charging simulations and bidirectional power flow for vehicle-to-grid (V2G) applications, helping validate energy efficiency and grid interaction. This enables comprehensive testing of HEV / EV components, ensuring reliable performance across diverse road and charging environments.
