Electric vehicles are not exactly the lightest vehicles around. Despite not having an engine or transmission, these vehicles do carry heavy batteries that make up most of the EVs' weight. In order for electric vehicles to cover hundreds of kilometers before needing a recharge, having large capacity batteries are a must.
Jaguar Land Rover, however, wants to change all that. In order for future EVs to cover more ground without impacting carbon emissions, JLR wants to make these vehicles lighter and faster.
The company plans to do this by developing lightweight vehicle and powertrain structures made from composites. JLR says the lightweight material will be capable of handling the increased torque generated by high-performance motors while improving efficiency and cutting CO2 emissions at the same time.
With extensive use of composites, JLR is also looking to reduce the weight of electric vehicles by 35 kg and increase stiffness by 30% This will also allow them to fit larger batteries on the lightweight platforms, without affecting CO2 emissions.
By 2022, JLR expects to have developed a fleet of prototype test vehicles using the lighter, stronger composite materials.
“The development of new lightweight body structures to complement the latest zero-emissions powertrains will be key as the electrification of our vehicle range continues. This project will allow the true environmental credentials of electric vehicles to be realized by enabling wider adoption of the technology and will propel Jaguar Land Rover and the UK supply chain into a world-leading position in low-carbon technology,” said Marcus Henry, Research Manager at JLR.
With the UK planning to ban the sales of new gasoline, diesel, and hybrid cars by 2035, JLR's plan to make EVs lighter may help the country move towards a zero-emissions future. In addition, JLR says that between 2023 and 2032, the project could help prevent the release of 4.5 million tons of CO2.
