Abstract:

The increasing rate of pollution due to vehicles has forceddown all the major nations to set the new limits of emission rate as well as fuel consumption rate, for both present and future. To meet these limit values, theautomotive industry is continuously developing various technologies such as improved aerodynamics, lightweight design, more efficient transmission, regenerative braking, advanced exhaust pipe, low rolling resistance tires etc. But almost all the technologies have reached their performance limits and their further improvement results in very small changes. The advantages of high voltage system have already been purposed by the Hybrid vehicles and Electrical vehicles.The introduction of 48V technology has produced highly efficient and advanced mild-hybrid vehicles which are showing improved results compared to both the normal and hybrid vehicles. The 48V technology is advanced to the other high voltage technologies as well as being within the safety limits of 60V for prevention of human shock. The system has introduced various new technologies such as Starter-Generator which can work as the starter as well as torque provider during the motion of avehicle, advanced regenerative braking, electrically driven rearaxle, electric compressor, electric pumps, electric power steering pump etc. The best feature of the technology is that it can be installed easily in any vehicle segment along with the conventional 12V system, with slight variation in thearchitecture of vehicle, in both gasoline and diesel engine vehicles. The 48V system can provide from 12 to 15kw power, reduced fuel consumption by 10-20% and reduced exhaust emissions up to 15%. The technology gives an advanced base for the further trend of future technologies such as advanced electronic powertrains, replacing the conventional mechanical and hydraulic loads from powertrains with the electrical loads and the new electrical components in vehicles, resulting in further improvement in performance and efficiency. The commercialization of 48V technology can bring a new revolution in theautomotive industry.
