Abstract：

Too　high　temperature　of　a　lithium-ion　battery　pack　will　reduce　the　discharge　efficiency　and　accelerate　the　decay　of　battery　life.In　order　to　lower　the　temperature　of　the　battery　pack,　a　cooling　system　which　inserted　heat　pipes　among　the　batteries　was　designed.Based　on　the　actual　speed　of　electric　vehicle,　the　temperature　distribution　of　the　battery　pack　under　different　speeds　was　numerically　calculated.The　results　showed　that　the　discharge　current　and　the　heat　production　increased　sharply　with　the　increase　of　vehicle　speed,　the　discharge　current　reached　up　to　143　A　at　a　vehicle　speed　of　120　km·h-1,　and　the　battery　pack　temperature　exceeded　50　when　the　batteries　discharged　ending.Compared　with　the　natural　convection　cooling　system,　the　heat　pipe　cooling　system　made　the　average　temperature　of　the　battery　pack　reduce　4.6　and　the　temperature　difference　reduce　2.2.The　temperature　of　battery　pack　was　effectively　reduced　with　the　increase　in　length　of　condensation　section　of　heat　pipes.A　satisfactory　cooling　requirement　of　the　battery　pack　was　obtained　when　the　length　of　heat　pipe　condensing　section　was　50　mm.　©　All　Right　Reserved.
