摘要

This paper presents the SAFT position in the development of high power batteries to meet thernrequirements of hybrid vehicles and 42 Volt integrated starter alternator systems. At the battery level,rnthere are too many common aspects between these two automotive applications to consider themrnindependentlyrnThe paper will present the technical merits of the two high power advanced technologies that SAFT isrndeveloping to meet the market requirements. Actual data such as gravimetric power and energyrndensities, volumetric power and energy density, cycle performances, calendar life and safety will bernshared on the SAFT Ni-MH and Li Ion high products.rnBoth product lines have already demonstrated a cycling ability surpassing the requirementrncorresponding to mileage of a the vehicle during its life.rnCalendar life predictions, based on extrapolation of actual data show that both chemistries shouldrnachieve a life time equivalent to the lifetime of most vehicles.rnThe two technologies are therefore very good candidate to fulfill the high power applications of thernautomotive industry.rnThe major obstacle, as seen by the car makers, to the large introduction of these technologies onboardrnvehicles is the cost of these advanced technologies when it is compared to the “reference” LeadrnAcid battery.rnUp to now, price goals have been expressed by the car makers in term of dollar per kWh. Saft willrnshow why using the price of the energy to rate these high power products is misleading.
