摘要

We have developed Hybrid Electric Vehicles (HEV) with Battery Management System (BMS) for several years. At this time, we have developed the Hybrid Electric Vehicle using the Ni-MH battery. One of the most important technologies for BMS is the design of high voltage battery pack in terms of volume reduction, thermal balancing of battery module and keeping in optimal battery temperature range. These factors affect the battery life and cooling method according to driving profile in the HEV. This paper introduces three processes to design the high voltage battery pack for the HEV. The first concept is easy modification dividing into 3 boxes, which are battery pack, electric parts and cooling system. The second one is thermal balancing of battery modules minimizing the air resistance with the given cooling system. The last one is the volume reduction in mounting in the HEV. As a result, we have made and mounted the battery system using prismatic Ni-MH 30 modules (Panasonic EV Energy co~®) in the HEV. Furthermore, these method is not only to maintain optimal temperature but also to keep temperature within less than 6 degree between maximum and minimum difference during the serious charge/discharge profile in bench test.
