Pure　electric　vehicle　power　battery　is　the　only　resource　for　driving　energy.　The　batteries　of　pure　electric　vehicle　on　sale　generally　possess　heavy　weight　and　large　volume.　Different　ways　of　layout　for　battery　have　a　significant　impact　on　the　vehicle　vibration　and　ride　comfort.　This　paper　Aimed　at　building　the　power　battery　layout　models　schemes　of　one　pure　electric　vehicle　and　analyzing　the　virtual　prototype　simulation　model　of　vibration　comfort　to　obtain　the　best　way　of　battery　layout.　Finally,　three　layout　schemes　were　added　flexible　connections　to　fulfill　vibration　simulation　optimization.　Comparing　the　results　of　seat　vertical　acceleration　in　flexible　connections　with　the　results　in　the　rigid　body　model.　The　result　indicates　that　flexible　connections　can　improved　vibration　characteristics　significantly.　©　2016,　FISITA.　All　rights　reserved.
