CombiPower：电动汽车驱动和电网连接的联合功率单元CombiPower: A Combined Power Unit for the Drive and Grid Connection of Electric Vehicles
➀ 弗劳恩霍夫能源经济与能源系统技术研究所 IEE 在 'CombiPower' 项目中正在开发一种创新的多功能充电和驱动单元。该项目于 2023 年底启动，将持续到 2026 年 9 月。➁ 现代电动汽车配备了多种逆变器：交流或直流充电器、驱动逆变器以及用于在 400V 充电站为 800V 车辆充电的 DCDC 增强器。将这些逆变器组合成一个多功能驱动和充电单元具有减少系统体积和重量、提高效率以及最小化成本的潜力。➂ 模块化充电和驱动单元的双向结构不仅允许从车辆电池向电网反向馈电，而且通过其电网形成控制设计提供额外的固有电网稳定化，通过电网形成属性扩展了车辆到 X 功能。➀ The Fraunhofer Institute for Energy Economics and Energy System Technology IEE is developing an innovative, multifunctional charging and drive unit for electric vehicles in the 'CombiPower' project. The project started in late 2023 and runs until September 2026. ➁ Modern electric vehicles are equipped with a variety of inverters: AC or DC chargers, drive inverters, and DCDC boosters for charging 800V vehicles at 400V charging stations. Combining these inverters into a multifunctional drive and charging unit has the potential to reduce system volume and weight, increase efficiency, and minimize costs. ➂ The bidirectional construction of the modular charging and drive unit not only allows for the reverse feeding of electrical energy from the vehicle battery to the grid but also provides additional inherent grid stabilization through its grid-forming control design, expanding the Vehicle-to-X functionality through grid-forming properties.
