Hybrid vehicles make use of traditional fuels while being accompanied by electric motors and engines. Electric motors function as the auxiliary power of engines to improve low-speed power output and fuel consumption. Hybrid system can reduce fuel loss of traditional fuel vehicles and level down fuel consumption so as to save energy and reduce emission.
There are three types of hybrid power system by power:
First, 12V + Stop-Start System (Micro Hybrid) acts as the entry technology of hybrid vehicles. Micro hybrid vehicles can be accomplished only by adding a set of start-stop system to traditional cars, so that engines can stop running in the case of a red light or traffic congestion and resume working as long as clutches are stamped again. By this means, 5%-15% of energy can be saved and 3%-6% of carbon dioxide emissions can be reduced.
Second, 48V+ISG/BSG System. In 2011, several German automakers jointly launched the concept of 48V system, and constituted LV148 standards. 48V system supplies power to 12V system via DC/DC adapters so as to improve the existing 12V start-stop system. As an upgraded version of 12V start-stop system, 48V system supports extended load, enhances the fuel economy to 15%-20%, and only requires less than half of the costs of high-voltage hybrid technology.
Third, Full Hybrid (PHEV and HEV). The most widely used full hybrid P2 structure, for instance, connects motors and engines by clutches as well as links motors with transmissions through clutches as well. The system can enable idle speed start-stop, brake energy recovery, acceleration boost and battery electric driving.
By dynamical structure, hybrid power system falls into three types: Series Hybrid Electric Vehicle (SHEV), Parallel Hybrid Electric Vehicle (PHEV), and Power-Split Hybrid Electric Vehicle (PSHEV).
Major component suppliers are speeding up the 48V micro hybrid product process with higher requirements on fuel consumption and emissions in China. Delphi’s products have been applied in Honda Civic 1.6L (overseas edition) and will be used by another two automakers in 2017, and Continental also started mass production in 2016. Domestically, the world’s first 48V mass-produced car – Changan EADO Electric Type was first launched in November 2016.
726,000 electric passenger vehicles (including 424,000 EVs and 302,000 PHEVs) were sold worldwide in 2016, up 32.2% from a year earlier, claiming an approximately 0.84% share of global total automobile market. With intensified efforts in promoting electric cars on a global scale, electric passenger vehicle sales volume will grow to 1.8 million in 2020.
