- The main problem is caused by drivers who heat their cabins, a battery expert previously told Insider.
Tesla is facing backlash following a report that it created a secret team to suppress customer complaints about the range of its electric vehicles.
Reuters reported that the EV maker had created a “diversion team” last summer, which was tasked with canceling as many range-related appointments as possible.
The report says that Tesla received thousands of complaints from customers who were unhappy with the ranges of its electric vehicles, highlighting one complaint that said the car was particularly affected by cold weather, an allegation the company has faced before.
Earlier this year, the automaker was fined around $2 million by South Korean regulators after being accused of exaggerating the range of their cars in cold weather.
The Korea Fair Trade Commission said that a typical Tesla’s battery performance dropped by around 50% in the cold.
But Tesla isn’t the only EV maker having trouble with its cold-weather range.
A Recurrent study that analyzed thousands of EV verified and estimated winter ranges suggested that battery performance on numerous models could drop anywhere from 3% to 32% in freezing conditions compared to 70 degree weather.
Why electric vehicle batteries don’t last as long in the cold
Venkat Srinivasan, a battery expert and director of the Argonne Collaborative Center for Energy Storage Science, said Insider’s Tim Levin that the main reason batteries drain more in the cold is that drivers heat their cabs.
While gasoline cars use heat generated Electric cars rely solely on battery power for their motors to heat passengers. Colder temperatures also slow down the chemical and physical reactions that make batteries work, by recurring.
Anna Stefanopoulou, director of the Institute of Energy at the University of Michigan, said wired that batteries were “like humans” and preferred temperatures between 60 and 80 degrees Fahrenheit.
“You don’t have that much power when you want to unload,” Stefanopoulou said. “The situation is even more constrained when you want to cash out.”
Charging electric vehicle batteries in cold climates
charging it can also be a problem in cold conditions.
Idaho National Laboratory reported that electric vehicle batteries can take up to three times longer to charge in cold temperatures.
Stefanopoulou told Wired that it’s important to try to keep electric vehicles at least 20% charged in sub-zero temperatures, as the vehicles need to use that charge to warm up the battery enough to start.
In December, Tesla owner and radio host Domenick Nati he said he tried loading his car in a Tesla Supercharger in 19 degree weather. But 15 hours later, he said his car had only gone 19 miles and he was forced to cancel his Christmas plans.
But some startups are looking to make cold weather woes a thing of the past.
Greater Bay Technology, a Chinese firm, told Bloomberg that its new “phoenix” cell can charge from 0% to 80% in six minutes — regardless of the outside temperature.
There are a few ways EV drivers can extend the battery life of their cars in cold climates. British car market auto trader He suggests putting the car in eco mode, which, when installed, helps direct power where it’s needed most and away from features like speakers.
He also suggests drivers keep their EVs covered when parked to help keep them warmer. The hotter they are, the more likely they are to hold their charge, he adds.
