NEW TECHNOLOGIES TO WATCH FOR

By Éric Descarries

The rapid growth of the electric car industry has, at the same time, created a whole new world of technology that is also growing at a tremendous rate. Not so long ago, it was believed that the electric car fleet would only increase in number and growth slowly. Today, we have to admit that it is growing at a very fast pace.

Perhaps the style of the cars still has something to say about the car industry. But what attracts our attention the most in recent years are the technical improvements and innovations included in the tidal wave of electric vehicles.

Batteries

If we consult publications with some expertise in the field, we quickly realize that it is mainly the evolution of batteries that captures our imagination. This evolution brings with it the creation of new materials, including thermal interface products, adhesives, seals, filters and so on. Beyond that, according to a report by experts at IDTechEx, the most common power that consumers should expect by 2030 is at least 400 kWh per battery pack.

Electronic components

In the same vein, we should see a whole new generation of electronic components such as on-board chargers, CD-CD converters, inverters and others, especially since several manufacturers have already announced 800-volt vehicle platforms, a niche that, once again, the IDTechEx report estimates will grow to 10% of the market by 2030. As you can see, that kind of electrical “power” will require more robust semiconductors, electrical wiring and frames!

Electric motors

Like batteries, the evolution of electric motors is booming in terms of both power and torque. The good news is that, according to IDTechEx, the development of axial flux motors and other recent discoveries could reduce the need for rare earth materials, if not eliminate them. In addition, we should expect a reduction in the size of such motors.

Fuel cells

Despite a slowdown in the development of fuel cells, some companies are pursuing their research. For the moment, it seems that only Toyota and Hyundai are interested in this technology, but recently, Honda and Suzuki (the latter being part of Toyota) have indicated their interest. As you may have understood, the major obstacle remains the lack of infrastructure for refuelling vehicles using such technology, which also translates into a high cost of hydrogen.

Autonomous vehicles

Finally, the most intriguing and exciting technology would be the development of autonomous vehicles—cars, vans or trucks that drive themselves without the supervision of a driver. IDTechEx does not believe that the technology will be commonplace for another 20 years or so, but who knows?
