Since a week now my Tesla Model X 100D won't charge as it used to. At my usual charging station 16/16 A it doesn't go faster than 14 km/hr... while it used to be 40 or 41 km/hr. I had the installation checked and bought a new cable but it won't help. At other public charging stations it is the same... at Tesla they told me that the cold winter temperatures are the problem which is somewhat hard to believe. At the super charger it still charges fast. Does anybody has had similar experiences?
