Electrical 48V coolant pump for highest thermal management requirements

Abstract

The EU parliament’s regulation sets the average threshold for CO₂-emissions at 95 grams per kilometer for new vehicles starting in 2020/2021 - in comparison with 130 g/km in 2015. This trend is continuing not only in Europe but in other regions of the world as well. Thresholds for CO₂ emissions in 2020 have been set to about 121 g/km in the USA (then 93 g/km starting in 2025), 117 g/km in China, and 105 g/km in Japan. In order to achieve this level, many mechanically driven components have already been replaced with electrical systems. The rising proportion of hybrid vehicles promotes the trend toward electrification. With regard to the development of the combustion engine, simplification or even elimination of the belt drive for engine auxiliaries characterizes efforts for future vehicles. Eliminating of the belt drive allows the friction in the combustion engine to be minimized, thus increasing its efficiency. This opens the door for fuel savings and therefore results directly in lower CO₂-emissions.
