  1. 1. Modularized Battery Management Systems for Lithium-Ion Battery Packs in EVs

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Yizhou Zhang; [2016]
    Nyckelord :battery management system; electric vehicle; Kalman Filter; Li-ion battery cell model; state estimation; BMS; elbil; Kalmanfiltrering; litiumjonbatterimodell; tillståndsestimering;

    Sammanfattning : The (Battery management system)BMS has the task of ensuring that for the individual bat-tery cell parameters such as the allowed operating voltage window or the allowable temperature range are not violated. Since the battery itself is a highly distinct nonlinear electrochemical de-vice it is hard to detect its internal characteristics directly. LÄS MER

  3. 2. Real Time Crowding Information (RTCI) Provision : Impacts and Proposed Technical Solution

    Master-uppsats, KTH/Industriell ekologi

    Författare :Yizhou Zhang; [2015]
    Nyckelord :Passenger distribution; Real time information; Passenger satisfaction; Crowding prediction; Passenger flow; Projection system; Speaker system; Practical test; Stockholm;

    Sammanfattning : The increasing population leads to higher passenger travel demand in Stockholm. The public transport becomes more and more crowded in rush hours. However, passengers carry out decisions usually based on limited traffic information and their travel experience. LÄS MER
