Together　with　a　network-based　bibliometricmethod　and　an　empirical　investigation　of　the　technology　evolution　of　modern　electric　vehicles　(EVs),　this　chapter　proposes　a　dynamic　method　to　ascertain　and　calibrate　technological　trajectories　and　describes　the　dynamic　nature　of　technology　changes　in　detail.　The　long-term　historical　technological　development　of　EVs　is　presented　with　the　identification　of　the　evolution　of　specific　technological　directions,　technical　bottlenecks,　and　problem-solving　heuristics.　Two　waves　of　EV　technology　development　and　the　dynamic　evolutionary　trajectories　in　the　second　wave　are　discerned　and　brought　forth　through　the　grace　of　the　proposed　dynamic　methods　with　the　extent　of　cumulativeness　and　persistence　at　the　knowledge　level.　©　2018　by　World　Scientific　Publishing　Europe　Ltd.　All　rights　reserved.
