  1. 1. Nanotubes for Battery Applications

    Författare :Sara Nordlinder; Kristina Edström; Torbjörn Gustafsson; M. Stanley Whittingham; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; vanadium oxide; nanotubes; lithium battery; Li-ion battery; XRD; PES; electrochemistry; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Nanomaterials have attracted great interest in recent years, and are now also being considered for battery applications. Reducing the particle size of some electrode materials can increase battery performance considerably, especially with regard to capacity, power and rate capability. LÄS MER

  3. 2. On Battery Electric Vehicles: Driving Patterns, Multi-Car Households and Infrastructure

    Författare :Niklas Jakobsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BEV; battery size; individual movement pattern.; Electro-mobility; GPS-logging;

    Sammanfattning : The transportation sector is responsible for a quarter of all greenhouse gas emissions in Europe. Though the transport system may be difficult to change into a less polluting system, electric vehicles may be a possible approach. LÄS MER

  4. 3. Adaptive model-based battery management - Predicting energy and power capability

    Författare :Björn Fridholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; state-of-charge estimation; state estimation; lithium-ion batteries; Battery management; parameter estimation;

    Sammanfattning : The battery is the limiting system for automotive electrication due to cost, size, and uncertain degradation. To be competitive the battery must therefore be used optimally. LÄS MER

  5. 4. Integrated Motor Drives and Battery Chargers for Electric or Plug-in Hybrid Electric Vehicles

    Författare :Saeid Haghbin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; maximum torque per Ampere strategy.; integrated motor drive and battery chargers; field-oriented control; battery charger; isolated and non-isolated integrated charges; Plug-in vehicles; split-phase PM motor;

    Sammanfattning : Plug-in vehicles, electric vehicles or plug-in hybrid electric vehicles, use grid power to charge the battery. The components in the traction circuit, like the electric motor and the inverter, are not used during the battery charging, so there is a possibility to use them in the charger circuit to reduce the size, weight and price of the on-board charger; that is called an integrated motor drive and battery charger or simply an integrated charger which can be galvanically isolated or non-isolated from the utility grid.

  7. 5. Thermal and State-of-Charge Balancing of Batteries using Multilevel Converters

    Författare :Faisal Altaf; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal balancing; Convex optimization; DC-link ripple; Battery ripple; Battery control; Hybrid electric vehicles.; Multilevel converter; Cell balancing;

    Sammanfattning : Driven by the needs to reduce the dependence of fossil fuels and the emissions of conventional vehicles there has in recent years been an increasing interest in battery-powered electrified vehicles (xEVs). In xEVs, the battery pack, built from many small cells, is one of the most expensive components in the powertrain. LÄS MER
