摘要：This addendum adds to the analysis of 'An innovation and policy agenda for commercially
competitive plug-in hybrid electric vehicles' ( D M Lemoine et al 2008 Environ. Res. Lett.3 014003 ) to the case of all-electric vehicles (EVs). We pay particular attention to
grid impacts, break-even battery costs, and the three ways in which EVs could
dramatically change the results we obtained for plug-in hybrid electric vehicles (PHEVs).
