  3. 3. Optimization of integrated energy storage for implicit demand-side flexibility : The case study of Singapore office buildings

    University essay from KTH/Kraft- och värmeteknologi

    Author : Tommaso Miori; [2020]
    Keywords : ;

    Abstract : Demand-Side Flexibility (DSF) is a very attractive option to solve challenges that are emerging from the evolution of modern power systems all around the world. The greater integration of intermittent renewable energy sources into the energy mix creates the need for flexible end-user behavior and demand management. READ MORE

  4. 4. Simulation of Intermittent Current Interruption measurements on NMC-based lithium-ion batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Daniel Lindqvist; [2017]
    Keywords : lithium-ion battery; NMC; internal resistance; measurement; COMSOL Multiphysics;

    Abstract : The objective of this report was to implement battery cycling and an intermittent current interruption (ICI) method for determining battery resistance into a simple lithium-ion battery model in the finite element methods (FEM) program COMSOL Multiphysics, andevaluate how accurately the model reflects the behaviour of voltage and internal resistance with respect to experimental results. The ICI technique consists of repeating the steps of first having a longer charging period and then having a short current interruption, where the internal resistance is calculated from the voltage drop that occurs when the current is turned off.

  5. 5. Development of battery models for on-board health estimation in hybrid vehicles

    University essay from KTH/Materialvetenskap

    Author : Javier Riesco Refoyo; [2017]
    Keywords : Lithium-ion battery; State-of-health; Resistance; Capacity; Materials; Model; Equivalent circuit model; Support vector machine; Neural networks;

    Abstract : Following the positive reception of electric and hybrid transport solutions in the market, manufacturers keep developing their vehicles further, while facing previously undertaken challenges. Knowing the way lithium-ion batteries behave is still one of the key factors for hybrid electric vehicles (HEVs) development, especially for the requirements of the battery management system during their operation.
