Development of Hyundai/Kia's LPI Hybrid Electric Vehicles

The history of Hyundai/Kia's hybrid vehicles is outlined and the latest model, the Elantra Liquid Petroleum Injection (LPI) hybrid is considered in more detail. It is based on a fly-wheel-mounted motor-generator type parallel hybrid system and is the first hybrid to use advanced Lithium Ion Polymer batteries. The six main components of the system architecture are described comprising i) the LPI engine, ii)the continuously variable transmission, iii) the electric motor with motor control unit, iv) the battery, v) the direct current/direct current converter and vi) the Hybrid Electric Vehicle control unit. Comparisons are made with conventional gasoline technology and details given of modifications made to improve fuel efficiency, thermal efficiency and mechanical efficiency. Detailed specifications are presented in tables and features presented diagrammatically. Other improvements noted are better aerodynamics, improved visibility of the instrument cluster and a creep aid system.
