• New electric Drive Module (eDM)
• Three ‘Concept_e’ vehicles
• Future electric, plug-in and hybrid cars
Pretoria – Jaguar Land Rover (JLR) has revealed its new low and zero emission engine technologies at the 2015 CENEX Low Carbon Vehicle event in England.
Three Concept_e research vehicles showcase technologies including a new unique high-performance, modular electric drive module (eDM) developed by the automaker.
According to JLR: "These are capable of producing twice the power and torque of any electric motor-generator in production today. These can be inserted between any engine and transmission to create Mild hybrid electric vehicles or Plug-in hybrids, or used alone for a Battery electric vehicle."
Led by Jaguar Land Rover, this two-year (started in 2013), £16.3-million research project is part-funded by Innovate UK1 and involves 12 UK technology partners2.
The three Concept_e research concepts are:
• Concept_e MHEV (Mild Hybrid Electric Vehicle)
A 'Mild Hybrid', based on a Range Rover Evoque, uses a prototype diesel engine (66kW) and a 48V electrical system. According to JLR: "It incorporates a 15kW 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."
• Concept_e PHEV (Plug-in Hybrid)
A Plug-In Hybrid employs a similar architecture to the MHEV but with a prototype petrol engine (220kW) mated to a eight-speed transmission mounted within a Range Rover Sport. The electric motor is capable of 150kW 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.
• Concept_e BEV (Battery Electric Vehicle)The concept BEV is a based on JLR’s aluminium vehicle architecture. The underbody has been modified to mount the 70kW/h HV lithium ion traction battery and electric axle drive (EAD) units. The front drive unit features a single speed transmission coupled with an 85kW electric motor. The rear drive unit features a twin speed transmission coupled with a 145kW electric motor.
New potential technologies
Jaguar Land Rover's director of Research and Technology Dr Wolfgang Epple said: “This is a long-term Jaguar Land Rover research project exploring all aspects of future hybrid and battery electric vehicle technology.
“The three Concept_e vehicles will allow us to test and develop exciting new potential technologies that could form part of our low and zero emissions vision beyond 2020.”
Jaguar Land Rover recently introduced Ingenium engines in the South African market. The low-emission, 2.0 litre diesel (132kW/430Nm) is available in the Jaguar XE sports sedan launched earlier in 2015.
