BYD Tang fails to impress Norwegian YouTuber Bjorn Nyland. Quite the opposite, in fact. He has found that the battery overheats at minus 9 degrees Celsius.
In a new 1,000 kilometer test, Norwegian YouTuber Bjorn Nyland ran into an unfortunately well-known problem – the Chinese BYD Tang showed signs of significant battery problems in winter conditions.
During the test, where the temperature dropped to minus nine degrees Celsius, the electric car's battery overheated. This inevitably affected the rest of the test, which actually had to be interrupted.
Nyland, known for its extensive range tests of various electric cars, is also surprised by the result.
The BYD Tang tested, which has a 111 kWh battery, was fully charged at the start of the test.
But after about 270 kilometers of driving, it was time for the first charge, where Nyland noticed that the battery was unusually warm, despite the low temperatures.
– It's really not good for the battery to be that hot, says Nyland in connection with the test.
He pointed out that the high temperature not only negatively affected the charging speed, but also indicated a potential problem with the battery's cooling system.
During charging, the battery continued to generate heat, and the temperature rose to 50 degrees Celsius, which worried Nyland.
He continued the test, but found that the problems only continued. On the next charge, the battery reached a temperature of 54 degrees Celsius. It didn't help the temperature in the battery pack either, as the car started to slow down.
Nyland chose to continue the test the following evening, when the temperature had risen to six degrees below zero.
Initially, there were signs of improvement as the battery stayed cooler, but after a short time the temperature rose again to 50 degrees Celsius.
– Imagine if I had taken the test during the summer at 25 degrees or in Thailand, Nyland remarks ironically about the challenges he faced.
Due to the ongoing charging problems, Nyland was forced to interrupt his long, but otherwise planned, drive.
He concluded that this was the third time he had been forced to end the test prematurely, and that all three times it was due to problems with Chinese electric cars.
