Can air extend an EV’s range?

The energy efficiency of electric vehicles (EVs) can be improved by 3 to 7% with proper tire inflation, according to a recent ExxonMobil study.

The first-of-its-kind study followed three identical EVs, each with different tire air-loss rates, as they each traveled 5,400 miles crisscrossing all sorts of environments in the United States, including city streets, small towns and rural roads, for six months.

The results showed that properly inflated tires enhanced EV energy efficiency by as much as 7% to extend vehicle battery range.

What if there were a way to increase an electric vehicle’s (EV’s) energy efficiency by 3 to 7 percent? A recent ExxonMobil study has revealed that proper tire inflation can do just that.

Back in 2018, the company embarked on a first-of-its-kind study that tracked EVs to understand the impact tire inflation pressure has on vehicle range. As the inventor of halobutyl rubber, the technological wonder that helps keep tires properly inflated, ExxonMobil wanted to take a hard look at the challenges EVs encounter.

The study followed three identical EVs, each with different air-loss rates. Each car traveled 5,400 miles, crisscrossing all sort of environments, including city streets and remote roads, for six months.

The results? In a nutshell, choose a tire that will stay better inflated over time. It will not only extend the life of the tire, but also the overall energy efficiency.

TECHRULES × TREV TECHNOLOGY

REVOLUTIONARY ELECTRIC VEHICLE TURBINE RECHARGING TECHNOLOGY NEARS PRODUCTION READINESS 

  • Chinese automotive R&D company, Techrules, will soon be ready to begin production of its innovative Turbine-Recharging Electric Vehicle (TREV) technology
  • New strategy set to launch technology in fixed and mobile charging stations as well as to commercial vehicle and passenger car OEMs
  • Smaller 15 kW turbine expands potential applications to include passenger cars, allowing for faster commercialisation
  • Discussions are at an advanced stage regarding location for the world’s largest micro-turbine production plant 

The Chinese automotive R&D company, Techrules, is approaching production readiness for its ground-breaking Turbine-Recharging Electric Vehicle (TREV) system which was showcased in the Ren supercar at the 2018 Geneva Motor Show. 

The TREV system is an all-new patent-protected series hybrid powertrain technology comprising a turbine-generator. TREV combines extensive experience of aviation and electric vehicle technologies with several patented technical innovations, delivering unprecedented levels of efficiency and performance, and ultra-low environmental impact especially with the use of renewable fuels.

Over the past year Techrules has made significant investments to grow its technical capabilities. World renowned electric vehicle expert Prof. Dr. Ching Chuen Chan is overseeing a newly-established Techrules R&D centre in Beijing. Prof. Dr. Chan is, amongst others, a member of the Chinese Academy of Engineering, a member of the Royal Academy of Engineering, and a Founding Chairman of the World Electric Vehicle Association. Under his guidance a smaller 15 kW turbine is now nearing its production readiness, making it suitable for commercial and industrial applications. 

William Jin, CEO of Techrules, said: “Since we showcased the Ren supercar with a twin 80 kW turbine set-up at the 2017 and 2018 Geneva Motor Shows, we received a tremendous amount of interest from OEMs around the world looking to benefit from its exceptional range-extending capabilities for passenger cars and commercial vehicles. So, we decided to adjust our strategy and develop a smaller and cheaper 15 kW version which is more suitable for commercial and passenger vehicles. This is allowing us to commercialise the TREV system much faster: we will be ready for mass production by the end of 2019.”

Techrules will use the TREV system in fixed and mobile charging stations as well as providing it to OEMs for use in commercial vehicles and passenger cars. 

In addition, Techrules is currently looking for a suitable international partner to help finalise the development and production of its Ren supercar, with a longer term aim to use its TREV system for its own passenger cars.

The inventor of the new micro-turbine technology, Chief Technology Officer of Techrules, Matthew Jin, explains: “The development of the Ren supercar is giving us extensive real-world experience that only cements our belief that large scale adoption of micro-turbines in electric vehicles will herald a new age for electric mobility. 

”Because the core technology of our turbine includes a brand new hybrid air bearing system, we have a previously unavailable route to mass-production of micro-turbines at a reasonable cost. And it can run on renewable fuels such as ethanol and biogas, which would smoothen the transition from the age of fossil fuels to the age of electricity. Because of its superior efficiency, fewer batteries are needed for electric vehicles, saving significant weight and cost, while also reducing emissions and, ultimately, urban pollution.”

Whether applied as a standalone charging system, or as a range extender in an electric vehicle, the micro-turbine can recharge batteries anywhere and at any time. It completely eliminates the problems of range anxiety and the inconvenience of lengthy charging times or poor charge point availability. Since it can use the existing infrastructure it avoids the challenges posed by the construction, cost and capacity of charging networks.

William Jin concludes: “We are in advanced discussions with a number of potential new partners to form strategic alliances. These will allow us to bring our technology, including the Ren supercar, to markets around the world, and to develop new products and commercial applications for our advanced TREV system. But our key priority now is to conclude the negotiations with local municipalities with the help of Professor Dr. Chan, in order to start building the largest micro-turbine facility in the world.”

Misconceptions of Driving an Electric Vehicle

Whitley, UK: Jaguar has today launched an intelligent app designed to help motorists experience life with an electric vehicle (EV), before actually owning one.

The Go I-PACE App captures journey data on a smartphone, notifying customers of how much money they’d be saving per trip, and how much battery they’d be consuming – delivering a clear indication of the time frame customers could go without charging their car.

In recent years, there has been a worldwide acceptance of electric vehicles, with over 1.9 million battery electric vehicles used globally in 2017. China is currently ranked as the largest market for all-electric vehicles, though countries like the US and Norway are also growing considerably, often triggered by government incentives such as subsidies and exemption from toll and parking fees.

According to recent reports by ‘The Society of Motor Manufacturers and Traders’ (SMMT), many British drivers are still mistrustful or confused when it comes to pure electric cars. Research has shown that more than 52% of consumers are interested in purchasing electric cars, but hesitate due to concerns such finding a charging spot, or not feeling like they know enough about how an EV actually works.

As a result, Jaguar has teamed up with Presenter and Independent EV Expert Robert Llewelyn, to help customers realise the benefits and simplicity of actually owning an electric vehicle.

Robert commented: “It can be hard for drivers to understand how an EV would fit into their day-to-day lives. The Go I-PACE app makes this possible by providing personalised information about how the Jaguar I-PACE could work for them based on real-world data. I’ve no doubt the app will surprise many users with the scale of the potential cost savings and by revealing how little change to their driving habits I-PACE ownership would actually make.”

With many governments around the world, including the UK, intending to cut emissions and improve air quality by 2030, the Go I-PACE app gives motorists the chance to prepare for the future.

The app is free to download and available now on Apple devices, and will be coming soon for Android:
