At the CENEX Low Carbon Vehicle event in the UK, Jaguar Land Rover (JLR) is showcasing three Concept_e research demonstrators—a mild hybrid, plug-in hybrid, and battery-electric vehicle—including a new novel high performance, modular electric drive module (eDM) developed in-house by Jaguar Land Rover.
These are capable of producing twice the power and torque of any electric motor-generator currently in production, JLR said, and can be inserted between any engine and transmission to create MHEV or PHEV, or used alone for a BEV.
The Concept_e technologies are the output of an advanced powertrain research program for state-of-the-art, next-generation hybrid and battery-electric powertrain technologies which began in 2013.
Led by Jaguar Land Rover, this two-year £16-million (US$25-million) research project is part-funded by the UK’s innovation agency, Innovate UK and involves 12 UK technology partners. (Earlier post.)
The three Concept_e research demonstrators include:
|Concept_e MHEV. The Mild Hybrid is based on a Range Rover Evoque donor vehicle and features a prototype diesel engine (90 PS) and a 48V electrical system. It incorporates a 15 kW crank-integrated motor with disconnect clutch within a hybrid module sandwiched between the engine and 9 speed transmission. The motor-generator is powered by an advanced 48-volt electrical system and 48-volt lithium ion battery pack. Click to enlarge.|
|Concept_e PHEV. The Plug-In Hybrid employs a similar architecture to the MHEV but with a prototype gasoline engine (300 PS) and 8-speed transmission longitudinally mounted within a Range Rover Sport donor vehicle. The electric motor is capable of up to 150 kW and also takes up the function of the starter motor. The motor draws electrical energy from a 320-volt lithium ion battery packaged in the boot. The hybrid powerplant drives through the conventional automatic gearbox normally fitted to the Range Rover Sport and the full time four-wheel drive system is retained. Click to enlarge.|
|Concept_e BEV. Concept_e BEV is a bespoke research demonstrator based on Jaguar Land Rover’s aluminium vehicle architecture. The underbody has been modified to mount the 70 kWh high voltage lithium-ion traction battery and electric axle drive (EAD) units. The front drive unit features a single speed transmission coupled with an 85 kW electric motor. The rear drive unit features a twin speed transmission coupled with a 145 kW electric motor.
