Study about Cooling Performance of LPB Pack Applied to Bimodal Tram

초록

Basic This paper have investigated 80Ah(650V) LPB considering the enough capacity to maintain required driving condition of bimodal tram(18m). LPB pack has 12 modules with 14cells per 1module. 1module is 14S1P and the normal voltage of 1cell is 3.7V. LPB performance is influenced by temperature variations which also affect to battery aging and cause diminishing of battery lifecycle. Therefore the less temperature variation gives LPB the better performance and the longer lifecycle. This paper has investigated the cooling performance of LPB pack with 200 cycles of driving cycle(during about 1minute) defined for bimodal tram.
