www.chinabuses.org: Hyundai developed its own homegrown hybrid architecture for using in its new vehicle. The technical design, known as a parallel hybrid system, will serve as the foundation for future hybrid drive vehicles introduced by Hyundai. In a parallel hybrid, the wheels are turned by power coming directly from the gasoline engine, the electric motor, or both together, as conditions demand. This approach is similar to the design used by Toyota and Ford.

The more significant innovation is the use of a lithium polymer battery system provided by Hyundai’s battery supplier, LG Chem. According to Hyundai, the lithium batteries deliver the same power as today’s hybrid nickel metal hydride batteries—but with 30 percent less weight, 50 percent less volume and 10 percent greater efficiency.
