  2. 1. Diffusion of Battery Electric Vehicles : The Role of Total Cost of Ownership

    Author : Jens Hagman; Sofia Ritzèn; Johan Jansson; KTH; []
    Keywords : Total cost of ownership; electric vehicles; e-taxis; vehicle salespeople; Machine Design; Maskinkonstruktion;

    Abstract : Due to their high efficiency, zero tailpipe emissions and possibilities of using renewable electricity, Battery Electric Vehicles (BEVs) have been proposed as a way to alleviate the negative consequences of transport. However, as with other energy-efficient innovations market uptake or diffusion of BEVs have so far been limited. READ MORE
