Fast charging is all the talk now but doubling then trebling the range is seismic. The world solves its problems by eliminating infrastructure. The 285 page IDTechEx report, "Routes to 1000 Mile (1600km) Battery Electric Cars 2021-2041" spells it out.
The report answers such questions as:
- Why is range improvement an ongoing, primary car battleground?
- What are the best ways of making affordable cars with 1000mile (1600km) range and when will it happen?
- What percentage of cars will have what best range 2021-2041?
- What percentage contributions from each technology and who leads?
- Detail on emerging simplification, lightweighting, solar bodywork, new components, batteries?
- What is the technology roadmap by year to achieving these ranges 2021-2041?
- Best ranges are currently achieved in different ways. How can we combine them?
- What other options will emerge from the research pipeline. When, from whom?
- What to believe about solid state batteries. Critically compare and predict?
- Decade of huge improvement in lithium-ion battery format, software, chemistry, cost. Detail and timing?
- What about supercapacitors, multifunctional composites, the two zero-emission range-extender options?
- Lessons from 30 different approaches from 30 vehicle companies appraised?
IDTechEx heavily discounts many promises, given the history of over-optimism, but it predicts strengthening demand for range, giving the many reasons why, and huge progress towards it. Learn how the technologies enabling long range bring other delights. Solar bodywork gives gentle users travel without ever using a charging station and the first get-you-home feature. If you drain the battery, you just wait and the body charges the car enough to get to a charger. Lightweighting aids acceleration and cost. The day is coming when there is no reason to buy a car that needs frequent charging.
Researched by multilingual PhD level IDTechEx analysts worldwide, the unique 285 page IDTechEx report, "Routes to 1000Mile (1600km) Battery Electric Cars 2021-2041" starts with an Executive Summary and Conclusions. Here you see the many reasons for increasing maximum range, the existing and the planned enabling technologies. Detailed infograms show trends, achievements, research pipeline with roadmaps 2021-2041. See when there will be wide availability of given long ranges and the percentage of cars with them. Quantified are the four primary contributors to widely-available range being 760 miles in 2031, up a startling 2.4 times on today. IDTechEx calculations are discounted by factoring in past over-promising by developers and OEMs and by deep analysis of technical and scaleup challenges and solutions ahead. For example, contrary to popular understanding, the next decade is not primarily about solid state batteries though they figure strongly in 2031-2041 forecasts and roadmaps presented for range extension.
Chapter 2 Introduction concerns perpetual cars, relevant smart city issues, geopolitical implications, iterative methodology for introducing range-extending technologies. A sensible starting point for the detail is Tesla, the world's most valuable auto company, because it got there largely by offering longest range and being exclusively focussed on battery-electric vehicles. Chapter 3 "Tesla Holistic Approach" describes how it has achieved range by many small things such as cable elimination, more efficient motors, low drag factor, best batteries. See how it will go much further with massive simplification beyond those giant aluminium diecastings. Read its advice on how to design motors.
Then come chapters on the technologies emerging with many new examples. Chapter 4 is on simplification and lightweighting to increase range. See in-wheel and eAxle motors with integrated power electronics, voltage increase shrinking cables and motors, structural energy storage, in-mold, 3D, transparent and edit-able electronics and electrics, merging components, new battery-cooling achievements, multi-functional composites. This is a 20 year view including Rivian, VW Group and other innovators. It is supported by a detailed jargon buster at the start of the report and by company profiles.
Chapter 5 concerns solar cars with increased range. This just got serious with major moves by Hyundai, Tesla, Toyota, VW Group and other giants plus startups selling solar vehicles, not just dreaming. How did Sono Motors get over 13,000 orders by emphasising all-over solar? The many solar formats such as film-wrap or load-bearing are critically appraised and the roadmaps and benefits are compared now and in future, even unfolding, sun tracking and super-efficient versions. Chapter 6 dives into the chemistries with many actual examples of single crystal silicon, CIGS and GaAs on cars, comparison charts, edit-able, multijunction and other options even metamaterial-boosting and comparison of solar cars that never plug in.
The 26 pages of chapter 7 deeply examine batteries and supercapacitors increasing range. Here is the structural battery, module elimination, potential disruptors to lithium-ion quantified and criticised, questioning trumpeted solid-state car batteries promised in cars 2024-6. See academic figures for energy density improvement by chemistry into the future then IDTechEx prediction of commercially available energy density by year. Chapter 8 presents range increases from future thermal management. Chapter 9 gives 20 company profiles each accompanied by SWOT analysis. This focuses on what they are doing to extend car ranges.
