“Extreme cold introduces safety risks for charging batteries,” says Paul Gasper, a staff scientist at the National Renewable Energy Laboratory’s Electrochemical Energy Storage group. Scientists generally consider lithium-ion batteries safe to use in a relatively
But recent mishaps, such as the stalling of cars in Chicago, show how current EV technology could flounder as future weather gets even more extreme: climate change continues to drive up average global temperatures, but this disrupts patterns that have long regulated the planet’s weather—so overall warming can usher in worse cold snaps.
The scientists say this could let batteries quick-charge even at temperatures as low as –58 degrees F (–50 degrees C). Other approaches, such as harnessing pulses of electric current from the car’s motor, can also warm up batteries for faster charging in the cold.
The rechargeable lithium-ion batteries that power most EVs perform poorly in the cold, so scientists and carmakers around the world are busy scrambling for solutions.
