Modeling and optimization of electrical vehicle batteries in complex clean energy systems

摘要

The paper presents a general temperature-dependent model for a family of batteries developed for electrical vehicle (EV) use. In addition to the model's derivation, the methodology and instruments developed to accurately measure the temperature-dependent parameters are also presented together with a Matlab/Simulink block for a temperature-dependent battery. This information is very important for simulating the behavior of an EV in real-life weather and temperature conditions and for simulating the quick charging process, which are key issues for spreading EVs. The battery model has been verified in a complex energetic structure consisting of a harmonic controller that minimizes the amplitudes of the 3rd, 5th, 7th, 9th, and 11th higher order components of the output voltage and that of the connection voltage controller, which controls the energy flow between the low voltage network and the renewable energy source, thereby reducing the power loss of the whole low voltage transformer area and reducing the CO_2 emission of the average household.
