The　charge-discharge　performance　of　lithium-ion　battery　as　a　vehicle　power　battery　is　affected　by　low-temperature.　Heating　lithium-ion　battery　at　low-temperature　conditions　toincrease　the　temperature　can　improve　the　charge-discharge　peformace　and　available　capacity　ratio.　To　study　the　effect　of　the　charge-discharge　performance　of　lithium-ion　battery　with　new　heating　method　using　heat　pipes,　the　performance　tests　were　conducted　under　the　different　low-temperatures.　The　results　showed　that　the　charge-discharge　performance　dropped　significantly　in　low-temperatures,　and　the　charge-discharge　performance　could　be　visibly　improved　by　heating　with　heat　pipes.　Heating　method　with　heat　pipes　could　significantly　reduce　the　heating　time.　Under　the　condition　of-30,　the　heating　power　of　30W　could　increase　the　battery　rise　temperature　by　30　within　20　minutes,　the　discharge　capacity　and　charge　capacity　increased　39.95%　and　86.44%,　respectively.　This　study　provided　a　new　technical　method　and　data　for　using　lithium-ion　batteries　efficiently　in　low-temperature.　©　2017,　Chemical　Industry　Press.　All　right　reserved.
