The battery life of electric vehicles has always been the focus of many skeptics, who often claim that the batteries will decay quickly and need to be replaced frequently. However, more and more facts have proven that these doubts may not be reliable.
Recently, according to foreign media InsideEVs, a 2018 Tesla Model 3 Performance has created a new milestone: the mileage has exceeded 200,000 miles (about 321,900 kilometers), and the battery capacity has hardly shown any significant attenuation. The owner said that the vehicle’s range and performance have been stable over the past 50,000 miles.
Generally speaking, the degradation of electric vehicle batteries is most obvious in the first 75,000 miles or so, after which the degradation rate slows down significantly, which was also confirmed by this Model 3 owner.
According to the owner, almost all of his charging is done at Supercharger stations, from a low state of charge to 95% or 100%. He monitors the battery health in a variety of ways, and combined with RecurrentAuto’s report, the car’s battery capacity has lost about 11-15%. Assuming that the vehicle has lost about 13% of its battery capacity, this means that this performance version of the Model 3, which originally had a range of 310 miles (about 498.9 kilometers), can now run about 270 miles (about 434.52 kilometers).
It is worth noting that in addition to the battery, other parts of the vehicle will also have problems with time and mileage. For example, the owner had the charging hardware repaired after 100,000 miles, and the air conditioning system began to show a decline in efficiency. However, these problems do not affect the core performance of the vehicle.
This case once again proves that battery technology for modern electric vehicles has made significant progress.
