Development of electric systems for hybrid and electric vehicles

This article presents improvement concepts of automotive electrical systems. 12-volt electrical systems are heavy and not effective for hybrid and electric vehicles. Author of this article performed study of energy consumption to analyze this problem. For this purpose 10 Channel Automotive Ammeter was developed. Current measurements were made in vehicle fuse boxes during test drives and simulation tests. Studies have shown that some circuits are overloaded and incorrectly designed. After summarizing of measurement results, author developed concept of Energy Distribution Controller with integration of Power Rail. This solution combined with 48-volt installations, will allow to developed efficient electric system for hybrid and electric cars.
