Bjørn Nyland just lately as soon as once more examined the battery capability of its Tesla Model 3 Efficiency, which beforehand misplaced 6% within 14 months and about 60,000 km (37,300 miles).

Because it seems, after shut to 2 years (22 months) and 80,000 km (50,000 miles), the battery degradation progressed additional to about 8%, in comparison with new.

It is fairly a considerable lower, however in Bjørn ‘s case, the automotive was driving quite a bit and likewise fast-charged quite a bit:

• DC charging whole: 11,813 kWh (60%)
• AC charging whole: 7,995 kWh (40%)
• Complete: 19,808 kWh

Throughout the take a look at, Bjørn estimated that the full obtainable vitality at 67.0 kWh (in comparison with 71.4 kWh nominal, indicated by the automotive, together with about 3.2 kWh buffer. When new, the automotive had 73 kWh.

The newest and former outcomes of whole battery output (vitality obtainable) are as follows:

• April 27, 2019: 73 kWh
• October 15, 2019: 69.6 kWh (-2 kWh by software program?)
• June 13, 2020: 68.8 kWh (6% degradation)
• February 6, 2021: 67.0 kWh (8% degradation)

Bjørn explains additionally that the chilly temperature (-13°C) may have an effect on the take a look at end result, nonetheless, in all probability not that a lot. Possibly it could be a 7% or 7.5% loss.

Anyway, at this level, it appears that evidently the battery degradation goes down by 1% per 10,000 km (6,200 miles) and 1% per 11 weeks. If nothing adjustments, 80% of the preliminary capability (20% degradation) ought to be reached at 200,000 km (124,300 miles) or inside 5 years, however that’s solely an extrapolation.
