As electric cars with more accessible and longer distances reach the market, the long-awaited transition to battery transport seems to be real. But there remains a serious challenge: cold time for battery suction.
New studies from the AAA reveal that when the mercury drops to 20 degrees Fahrenheit, the average speed of the electric car decreases by 41%. When colder temperatures hit, EV owners have the same instinct as the brothers with internal combustion engines, which is to develop the heat as high as it will go. This puts a serious strain on the EV battery, reducing the overall range and increasing the need to charge more often to reduce the chance of being stuck in a dead battery.
"The attractiveness of electric vehicles continues to grow as a wider variety of designs and options has increased in the market," said Greg Brann, AAA Director for Automotive Engineering and Industrial Relations, in a statement. "While drivers realize that there are restrictions on the operation of electric vehicles in more extreme climatic conditions, they are less likely to be caught unprepared by an unexpected drop in the driving range." hit Central America and Canada. As the temperatures fell, Chevy Bolts and Tesla Model 3s owners told CNBC that they saw a 50% smaller range in their vehicles.
Extreme heat is also the resistance of electric vehicles. When outdoor temperatures warm up to 95 degrees Fahrenheit and air conditioning is used inside the vehicle, the range of motion may decrease by 1
The problem is that, unlike a car with an internal combustion engine that can heat the cabin with heat, the motors must be plugged into their batteries to trigger the climate control system.
Less battery power means more charging, which increases the cost of operating the vehicle. The AAA study found that the use of heat when out of 20 degrees Fahrenheit added nearly $ 25 more every 1000 miles compared to the cost of combined urban and highway driving 75 degrees Fahrenheit.
AAA tests five electric vehicles – the BMW i3, the Chevy Bolt, the Nissan Leaf, the Tesla Model S and the Volkswagen e-Golf – all with a minimum distance of 100 miles. The actual driving conditions were simulated using a dynamometer, which was essentially a giant treadmill, in a closed test cell where ambient temperature could be controlled.
In order to determine the impact on the driving area, the cold and hot weather scenarios – both for HVAC use and for – were not compared with those at normal outside temperatures. Surprisingly, AAA has found that the impact on the range is almost the same between the tested cars.
Manufacturers of electromobiles have to find a way to communicate the effect of the extreme climatic conditions of the customer as they strive to increase their sales market. At the same time, owners can take some steps to help mitigate the effects of heavy heat and cold on their vehicles, says AAA. Take some time to pre-heat or pre-cool the car while it is still connected to a charger. Plan for frequent stops to charge if you travel longer so you do not get caught on the side of the road with a dead battery.
