Electric　vehicles　are　an　effective　tool　to　reduce　vehicle　born　emissions　from　road　transportation.　Faced　with　major　pollution　issues,　China　is　committed　to　vigorously　promoting　electric　vehicles.　China　has　made　active　efforts　in　subsidies,　policies,　charging　facilities,　business　models,　etc.,　so　that　the　annual　growth　rate　of　electric　vehicle　sales　has　accelerated.　State　subsidies　have　greatly　promoted　the　use　of　electric　vehicles,　but　the　government　is　gradually　reducing　subsidies.　In　the　case　of　government　subsidy　decline　or　even　zero　subsidy,　＂separation　of　vehicle　and　battery＂　is　considered　to　be　a　good　mode　for　solving　the　development　of　private　EVs.　The　battery　of　an　electric　vehicle　does　not　form　a　whole　with　the　chassis,　but　they　could　be　physically　separated,　replacing　the　battery　with　one　which　is　fully　charged　instead　of　charging　by　users　themselves,　substituting　battery　leases　for　battery　purchases,　called　separation　of　vehicle　and　battery.　However,　a　series　of　issues　such　as　whether　this　mode　is　beneficial　to　consumers,　whether　it　has　competitive　advantages　for　vehicle　companies,　and　what　difficulties　exist　need　to　be　further　studied.　This　paper　firstly　analyzes　whether　it　is　necessary　to　implement　＂separation　of　vehicle　and　battery＂　for　private　electric　vehicles　(SEPARATION)　in　China.　Based　on　this,　it　sums　up　the　attempts　of　two　companies　to　implement　SEPARATION　and　extracts　the　key　factors　involved　in　SEPARATION.　Then,　such　key　factors　are　analyzed,　and　the　customer　delivered　value　model　of　SEPARATION　is　established.　Finally,　this　article　discusses　the　predicament　of　SEPARATION　and　makes　some　recommendations　for　the　implementation　of　SEPARATION　in　China.　The　innovations　in　this　paper　include:　(1)　Analyzing　the　issue　of　SEPARATION　from　the　perspective　of　customer　delivered　value.　(2)　Proposing　a　customer　delivered　value　model　of　SEPARATION　for　the　first　time.　(3)　Proposing　a　two-level　battery　replacement　network　in　the　SEPARATION　mode.
