In parallel hybrids, the ICE and the electric motor are both connected to the mechanical transmission and can transmit power to drive the wheels. Hybrid electric vehicle can be classified according to the way in which power is supplied to the drivetrain. Many HEVs reduce idle emissions by shutting down the internal combustion engine at idle and restarting it when needed.Ī hybrid-electric vehicle produces less emission than a pure-gasoline burning vehicle. Some HEVs use their internal combustion engine to generate electricity by spinning an electrical generator. Modern HEVs use improved technology which converts the vehicle’s kinetic energy into electric energy. The aim of the electric powertrain is to achieve better fuel economy or better performance.

The world's mainstream OEMs have conducted diversified explorations in hybrid systems, and finally chose the hybrid strategy that is most suitable for their own models. In 2020, 32,600 Lixiang ONE cars were sold, ranking first in the extended-range field.
Parallel hybrid vehicle example series#
In series mode, the engine and the electric motor are not mechanically connected, so the engine can obtain the best efficiency at different vehicle speeds and loads. The series extended-range hybrid power roadmap is represented by Nissan e-Power, Lixiang ONE, Dongfeng Voyah, etc. For example, the GAC Trumpchi Electromechanical Coupling System (G-MC) adopts the series-parallel mode, which is mainly used for plug-in hybrid BYD's DM-i super hybrid technology adopts the EHS to open up a new technology system in addition to Toyota's THS Power-split and Honda's i-MMD. A large number of Chinese plug-in models have exploited German technology roadmap and suppliers.Ĭhinese automakers have transferred from the original technology diversification to the dual-motor-based series-parallel mode. The system replaces traditional lead-acid batteries with power-type lithium-ion batteries with a voltage of 48V and an energy of less than 1kW - h, and replaces traditional starter motors and generators with B/ISG motors. German cars are mainly based on 48V low-voltage and high-voltage hybrid technology arranged in P0/P2. For example, the new-generation GAC Trumpchi GS8 hybrid system is planned to be equipped with the Julang Hybrid System composed of Trumpchi 2.0T engine and Toyota THS Hunan Corun New Energy has purchased the core technology Toyota's THS for RMB1 and promoted the application in conjunction with Geely.Īmerican cars are mainly based on Power-split (PS) of GM and Ford for example, the general hybrid power system of GM LaCrosse adopts a dual-row planetary structure design to achieve two "power split" modes (high and low speed modes) and one or multiple fixed gears so as to further improve the fuel economy and transmission efficiency of the car. Toyota is committed to licensing the hybrid technology to Chinese automakers. For example, Toyota THS available in Toyota Prius adopts a single planetary row structure design to maximize fuel economy in common vehicle speed ranges. Through strong hybrid, the best fuel-saving effect can be achieved. Japanese cars are mainly powered by Toyota's Power-split (PS) and Honda's i-MMD series-parallel hybrid. Five global major hybrid technologies compete fiercely in ChinaĬurrently, hybrid power is mainly being developed in Japan, the United States, Europe, and China which choose different hybrid technology roadmaps according to their technical reserves and development goals:
