To　maintain　the　performance　of　the　power　battery　and　prolong　its　service　life,　the　temperature　and　temperature　difference　during　the　operation　of　the　battery　module　should　be　maintained　within　an　appropriate　range.　Thus,　a　new　type　of　honeycomb　liquid-cooled　power　battery　module　is　proposed.　The　structure　has　an　inlet/outlet　guide　plate　inside　and　the　battery　is　honeycomb-like　distribution.　The　cooling　liquid　contacts　with　the　battery　indirectly　at　360°,　which　greatly　strengthens　the　heat　transfer　effect.　On　the　basis　of　the　numerical　simulation　and　experimental　validation　of　the　thermal　characteristics　of　single　battery,　a　new　model　of　honeycomb　liquid-cooled　battery　module　was　established　by　computational　fluid　dynamics(CFD)　platform,　the　thermal　behavior　of　the　battery　module　was　studied,　and　the　effects　of　the　coolant　flow　rate,　the　coolant　temperature　of　battery　on　the　heat　dissipation　performance　of　the　battery　module　were　studied.　The　results　show　that:　(1)　Increasing　the　flow　rate　of　coolant　can　significantly　reduce　the　maximum　temperature　of　the　battery　module　and　improve　the　temperature　uniformity,　when　the　flow　rate　of　coolant　increases　to　1.5　L/min,　the　maximum　temperature　and　the　maximum　temperature　difference　of　the　battery　module　tend　to　be　stable;　(2)　Decreasing　the　temperature　of　coolant　can　significantly　reduce　the　highest　temperature　of　the　battery　module,　but　to　a　certain　extent,　the　temperature　uniformity　in　the　battery　module　is　deteriorated;　(3)　The　coolant　flow　rate　and　the　coolant　temperature　have　significant　influence　on　the　heating　characteristics　of　the　battery　module.　Therefore,　liquid　cooling　is　necessary.　©　All　Right　Reserved.
