Electric vehicles

In electric aircraft, motor power-to-weight ratio is paramount for endurance, the main constraint on sales. You cannot lug ever more battery weight to get range. Indeed, better motors mean less battery in a land, water or air vehicle. The new IDTechEx Research report, "Electric Motors for Electric Vehicles: Land, Water, Air 2019-2029" explains the new emphasis on power-to-weight ratio with good efficiency.

IDTechEx is hosting a free webinar on Thursday 28 March 2019 titled Electric Motors for Electric Vehicles Land, Water, Air: $100+bn Market Emerging.

IDTechEx Launchpad will showcase innovations from 20 start-up companies at the IDTechEx Show! held in Berlin, Germany on 10-11 April 2019. All winners will be showing a new working prototype or product, many for the first time.

IDTechEx CEO Raghu Das identifies 3 of the most important technology trends that you need to know about this year.

The electric vehicle population has accelerated around the world, surpassing four million units for the first time in 2018. Producers have responded to consumer's range anxiety by increasing the available range per charge in their vehicles. However, ultimately the deployment of electric vehicles will depend on the deployment of ubiquitous chargers, which can also help mitigate peak energy demand on the grid with v2g functionality.

Traction motor sales grow faster than electric vehicle sales because small vehicles such as mobility for the disabled have two motors. IFEVS has put two in microcars for four-wheel drive. In larger cars, two motors is now commonplace for economy, performance, four-wheel drive, vectored steering and attack survival.

Car demand will collapse as people move to cities. $100 billion was written off the stock value of car companies recently. The US economy is on a sugar rush from a trillion-dollar borrowing boost at the top of the cycle. Climate change getting out of control in 12 years? These and many other negative indicators can portend a recession, maybe a severe one. What are the implications for EVs?

Bad strategy rather than tactics, such as misjudged new models, will kill several major automotive companies. They face a perfect storm of peak car, totally new technology, totally new markets and recession.

It is a rule-of-thumb that manufacturers should vertically integrate only when products and markets mature, so they can confidently shave off the last pennies of cost. One exception is when shortages loom: Tesla built its battery gigafactory fast using proven Panasonic technology. However, many suppliers now build battery gigafactories.
