Study about the Application of LPB for the Propulsion System in Bimodal Tram

초록

We are now developing the environmentallyfriendly public transportation system and more for disabled persons. Newly developed tram what is called Bimodal tram(BT) has adopted lithium polymer battery(LPB) for the propulsion system which is series-type of hybrid vehicle. BT use the range of 600~700Vdc as the applied voltage for the propulsion of vehicle. So LPB(80Ah) pack for BT consisted of 168 cells which has 705V as 4.2V of LPB cell voltage. This paper has investigated the characteristics of LPB cells and then the thermal distribution of battery module and completed LPB pack.
