Tesla Motors has maintained that the most recent fire involving one of its Model S electric vehicles isn't the result of a vehicle or battery malfunction, but the company is still addressing the situation with a software fix, according to Green Car Reports. The California-based automaker has added a software function that automatically reduces the charge current by about 25 percent when power from the charging source fluctuates outside of a certain range, Green Car Reports says, citing the Twitter feed from an Apple employee, @ddenboer, who owns a Model S. You can read the text of the update below.

Last month's fire in an Irvine, CA, garage was the fourth involving a Tesla this year. The company cited an investigation by the Orange County Fire Authority and said the incident was caused by a wall-charging system that overheated and not by the luxury sedan itself. Meanwhile, the National Highway Traffic Safety Administration (NHTSA) continues to take a closer look at the other three Tesla fires, all of which took place during the fall. Two of the fires - one in Tennessee and another near Seattle - were caused by metal debris in the road that struck the bottom of car and hit the car's battery with such great force that the battery was punctured.

Automatic Charge Current Reduction

If the Model S onboard charging system detects unexpected fluctuations in the input power to the vehicle, it will automatically reduce the charging current by 25%. For example, this will reduce a 40 amp charge rate to 30 amps.

This charge is designed to help protect you even when a problem exists that is outside of the car or charging electronics. It should significantly increase robustness and safety in the unlikely situation that a home wiring system, receptacle, adapter or cord is unable to meet its rated current capacity.
