Temperature　affects　the　performance　of　electric　vehicle　battery.　To　solve　this　problem,　micro　heat　pipe　arrays　are　utilized　in　a　thermal　management　system　that　cools　and　heats　battery　modules.　In　the　present　study,　the　heat　generation　of　a　battery　module　during　a　charge-discharge　cycle　under　a　constant　current　of　36　A　(2C)　was　computed.　Then,　the　cooling　area　of　the　condenser　was　calculated　and　experimentally　validated.　At　rates　of　1C　and　2C,　the　thermal　management　system　effectively　reduced　the　temperature　of　the　module　to　less　than　40　degrees　C,　and　the　temperature　difference　was　controlled　less　than　5　degrees　C　between　battery　surfaces　of　the　module.　A　heating　plate　with　30-W　power　effectively　improved　charge　performance　at　low　temperature　within　a　short　heating　time　and　with　uniform　temperature　distribution.　Charge　capacity　obviously　increased　after　heating　when　battery　temperature　was　below　0　degrees　C.　This　study　presents　a　new　way　to　enhance　the　stability　and　safety　of　a　battery　module　during　the　continuous　charge-discharge　cycle　at　high　temperatures　and　low　temperatures　accordingly.
