The "CENEX Low Carbon Vehicle" held by the Jaguar Land Rover (JLR) Group on September 9, 2015 in the United Kingdom, released the concept "Concept_e" of the zero emission and low emission power transmission system.
Concept_e's demonstration models include the three hybrid models "Concept_e MHEV", plug-in hybrid "Concept_e PHEV" and pure electric vehicle "Concept_e BEV".
The Concept_e MHEV is based on the "Range Rover Evoque", a combination of a 66kW (90PS) diesel engine and a 48V electrical system. A 15 kW crank motor with clutch is incorporated in the hybrid module located between the engine and the 9-speed gearbox. This motor and generator is driven by a 48V electrical system equipped with a 48V lithium ion secondary battery.
The Concept_e PHEV is based on the "Range Rover Sport" and has the same structure as the MHEV, but it has a trial-production gasoline engine with an output of 220 kW (300 PS) and an 8-speed gearbox. The maximum output power of the motor is 150kW and it also serves as a starter. The power supply of the motor is a 320V lithium ion secondary battery. Regular four-wheel drive is achieved with the original automatic transmission.
Concept_e BEV is a platform specially developed based on the aluminum framework of Jaguar Land Rover Group. Equipped with 70kWh high-capacity lithium ion secondary battery and electric drive system. The front-side reducer and the 85kW-powered motor drive the front wheels, and the rear 2-speed gearbox and the 145kW motor drive the rear wheels. Reducer and 2-speed gearbox "eAxle" are manufactured by GKN Driveline.
Concept_e is a project to study advanced technologies for low-carbon vehicles such as the new generation of hybrid and electric power transmission systems. Under the leadership of the Jaguar Land Rover Group, 12 organizations including universities and suppliers have cooperated to start research in 2013. The investment in the past two years was 16.3 million pounds. Innovate UK, a public body supported by the British Ministry of Commerce, Innovation and Skills, provided some funds for the research project.
Partners include Zytek Automotive, GKN Driveline, Motor Design, AVL, Drive System Design, Williams Advanced Engineering, Delta Motorsport, Tata Steel, University of Bristol, Cranfield University (Cranfield University) and Newcastle University. (Reporter: Shibuya Shajiangzi)
