    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

  4. 4. Impact Simulation of Adhesively Joined Structures

    Detta är en avhandling från Chalmers tekniska högskola

    Författare :Thomas Carlberger; Högskolan i Skövde.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive joining; Dynamic fracture; Cohesive zone; Interphase Element; Bi-material joining; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik; Teknik; Technology;

    Sammanfattning : The development of competitive and crashworthy automotive car bodies has reached so far that the manufacturers no longer rely on mono-material steel structures. Improved strength/weight performance may be achieved by using optimal material in each part of the car structure, leading to bi-material joints and ruling out spot welding; the common joining method during the past half century of automotive history.
