JAGUAR LAND ROVER Plug-In Hybrid and Mild Hybrid technologies
- Jaguar Land Rover reveals unique electric Drive Module (eDM) technology that could be used to create future low and zero-emissions vehicles
- Three ‘Concept_e’ research demonstrators showcase potential future Battery Electric Vehicle, Plug-In Hybrid and Mild Hybrid technologies
Pretoria, 9 September 2015 – Jaguar Land Rover has revealed some of the new and innovative low and zero emission powertrain technologies it is researching at this year’s CENEX Low Carbon Vehicle event, held in the UK.
Three Concept_e research demonstration vehicles showcase this far-reaching future research, which includes a new unique 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 in production today. These 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 product of an advanced powertrain research programme 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, £16.3m research project is part-funded by Innovate UK1 and involves 12 UK technology partners2. It has brought together leading engineers and technologists from academia, the supply chain and industry to create a number of unique and innovative solutions.
“This is a long-term Jaguar Land Rover research project exploring all aspects of future hybrid and battery electric vehicle technology,” said Dr Wolfgang Epple, Director of Research and Technology, Jaguar Land Rover. “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.”
“The project is also helping to develop the UK’s skills and capabilities in alternative powertrains. We are serious about helping the UK become a worldwide leader in powertrain technologies. Collaborative research programmes like this allow us to multiply the effect of our own R&D investment and nurture the UK’s technology supply chain. This approach is helping to develop the skills and technologies that will make the UK even more competitive in the future.”
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 (66kW) 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.
- Concept_e PHEV. The Plug-In Hybrid employs a similar architecture to the MHEV but with a prototype petrol engine (220kW) and 8 speed transmission longitudinally mounted within a Range Rover Sport donor vehicle. The electric motor is capable of up to 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 is a bespoke research demonstrator based on Jaguar Land Rover’s aluminium vehicle architecture. The underbody has been modified to mount the 70kWh 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.
“Environmental Innovation is at the heart of our business. We have a wide-ranging low emissions technology strategy, which has created innovations like our Ingenium engine family and lighter vehicles,” said Dr Epple. “Technologies like these have already helped us reduce our fleet CO2 average by 25 per cent in recent years.”
As part of its environmental commitment, Jaguar Land Rover recently introduced Ingenium engines in the South African market. This low-emissions 2.0-litre diesel powerplant, producing 132kW and a class-leading 430Nm of torque, is available in the Jaguar XE sports sedan, and will be available in additional vehicles in the future.
“Our future vision is to continue to reduce emissions and improve fuel efficiency while still delivering the luxury, performance, refinement and comfort our customers expect,” said Dr Epple. “Whether it’s optimising the internal combustion engine, advanced hybrid and battery-electric propulsion systems, the introduction of new, lightweight materials or the improvement of energy conservation through more efficient heating and ventilation technologies, we are leaving no stone unturned to ensure Jaguar and Land Rover vehicles emit significantly less emissions in the future.”
