Parameteranpassungsschema für hybride Energiespeichersysteme
Eine der größten Herausforderungen des 21. Jahrhunderts ist der Wechsel zu klimaneutralen Energiequellen. Eine Schlüsselrolle spielt dabei die zuverlässige Energiespeicherung, denn Erzeugungs- und Lastspitzen im
How to optimize a series-parallel hybrid electric vehicle?
In order to obtain the optimal design of the system, it is necessary to integrate the physical system and its controller. Taking component parameters and energy management strategy as research objects, this paper elaborates an integrated optimization approach for a series–parallel hybrid electric vehicle.
What are hybrid energy storage systems?
Hybrid energy storage systems that combine lithium-ion batteries and supercapacitors are considered as an attractive solution to overcome the drawbacks of battery-only energy storage systems, such as high cost, low power density, and short cycle life, which hinder the popularity of electric vehicles.
What is the hybrid energy storage system (Hess) approach?
At this point, the utilization of the hybrid energy storage system (HESS) approach, integrating storage technologies with supplementary operating characteristics, can be very beneficial. Section 2 discusses typical HESS-applications, energy storage coupling architectures and basic energy management concepts.
What is the power system of a hybrid electric vehicle (HEV)?
The power system of a hybrid electric vehicle (HEV) is composed of multiple power sources. The control strategy is used to realize rational power distribution among these power sources and coordinated control among components, so as to improve the performance of the vehicle .
How to design a hybrid electric vehicle?
For the design of the hybrid electric vehicles, the strong coupling between plant parameters and controller parameters turns the problem into a multi-layered challenge. If handled sequentially, it is defined as sub-optimal. In order to obtain the optimal design of the system, it is necessary to integrate the physical system and its controller.
What are the Hess-configurations suitable for decentralized PV-systems?
Four HESS-configurations, suitable for the application in decentralized PV-systems: (a) power-to-heat/battery, (b) power-to-heat/battery/hydrogen, (c) supercap/battery and (d) battery/battery, are briefly discussed. The paper ends with a short description of a modular HESS-experimental test-bed in its components, structure and functionality.
