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 demonstration vehicles showcased the
innovations, 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.”
“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.”
