Tesla updates battery software after Hong Kong, Shanghai fires

The company this week issued the update, which tweaks "charge and thermal management settings" in the battery out of "an abundance of caution".

The changes will "further protect the battery and improve battery longevity", according to the company. The move is in response to a pair of battery fires, one of which was captured on security cameras in a Shanghai parking garage. The video of the Model S is below.

"We currently have well over half a million vehicles on the road, which is more than double the number that we had at the beginning of last year, and Tesla's team of battery experts uses that data to thoroughly investigate incidents that occur and understand the root cause," Tesla said.

"Although fire incidents involving Tesla vehicles are already extremely rare and our cars are 10 times less likely to experience a fire than a gas car, we believe the right number of incidents to aspire to is zero."
