Vehicles going up in flames are not new to the electric era. An estimated 171,500 took place annually in the U.S. alone over a recent three-year period, and cars powered by the combustion of gasoline are plenty prone to catching fire.

The vehicle blazes are making a big impact before automakers have even managed to pin down their precise causes.
A flaw affecting a plug-in hybrid SUV in Europe will keep Ford from complying with tougher emissions standards this year.
BMW and Hyundai are recalling tens of thousands of cars, and GM is being probed by U.S. safety regulators.
"What we're seeing with new fires has more to do with the landslide of new EV models and higher sales in the last couple of years -- there are more fires because there are more EVs," said Sam Jaffe, managing director at Cairn Energy Research Advisors, a Boulder, Colorado-based consultancy.

A younger, tech-savvier population is one reason why China is the world's biggest EV market, JATO Dynamics said in a report earlier this week, with consumers in Europe and the U.S. more likely to stick with what they know.
