Tesla has installed Supercharger charging facilities for its EVs around the country, but these chargers are usually used exclusively for Tesla cars. Superchargers in Europe, however, may not be so much the case at the moment. Automotive information site Electrek reported that due to a software issue, Superchargers in Europe can (at least currently) charge non-Tesla EVs, such as the Volkswagen ID.3 and BMW i3, as well as other companies' EVs, just like Tesla cars.
For the convenience of charging EVs, Tesla uses the CCS standard, which is widely used in Europe, as the charging connectors for its vehicles sold in Europe. Tesla's Supercharger also uses CCS, but when an EV other than a Tesla car is connected to the Supercharger, Tesla's unique software will not "handshake" the car and start charging. This handshake process ties charge usage data to the Tesla owner's account and is also used to calculate costs.
However, when owners of non-Tesla EVs in Europe connected the charging connector at Tesla's newly installed Supercharger V3 charging facility, they found that they were able to charge their vehicles completely normally, and several reported cases have been revealed.
Electric vehicles confirmed to be (unintentionally by Tesla) compatible with the Supercharger V3 are as follows
Opel Ampera-e (Chevy Bolt EV)
Hyundai Kona Electric
Hyundai IONIQ Electric
The fact that these EVs can be charged by Supercharger V3 without problems is most likely due to a bug in the handshake process. Also, these EVs are not tied to a Tesla account, so they won't be charged when the charging process takes place.
Nevertheless, now that this unexpected behavior has become widely known enough to be publicly reported, there is no doubt that Tesla will be quick to debug the Supercharger V3 facilities. Tesla is offering a free period of Supercharger use as a benefit to some customers, but it's highly unlikely that they would be comfortable with a situation where another company's EVs would charge for free.
Tesla has previously stated that they intend to open up the use of the Supercharger network to other companies' EVs, but due to cost-sharing and other conditions, they have not been able to reach an agreement with any other company so far.
