The first Tesla V4 Supercharging station in Harderwijk, Netherlands is already installed and open for Tesla electric cars (but not yet included in the onboard navigation) so we can take a look at the first video reports from the site.
As we know, there are 16 individual stalls (CCS2-compatible) - taller than the older V3 and equipped with a longer cable, attached at the top, to provide easy access for more electric vehicles. Tesla said that soon the station is expected to be available also for non-Tesla EVs.
A new video, posted by electricfelix, presents a full experience of the V4 Supercharging of a Tesla Model 3. According to the video, the peak charging power of a pre-conditioned battery was about 160 kilowatts (kW), when arriving at 30 percent state-of-charge (SOC).
electricfelix noted also that the new stalls are visible from far and quite tall. There seem to be some quirks in the stall's plug dock, so it will be interesting to see how durable and reliable the new design is.
The cable appears to be really long, which is a good thing, and a brief look indicates that it might be long enough to charge a Tesla in a nearby spot. An interesting thing is that the stalls are positioned a little bit on the right from the center point, rather than in the middle of the spot.
According to a separate report posted by Teslarati (after Esther Kokkelmans, who visited the charger), the length of the charging cable increased from about 6-6.5 feet in the V3 version to 9.5-9.8 feet (calculated from 2.9-3 meters), which means some 50 percent increase. That should definitely help to charge non-Tesla EVs, which might have charging inlets in different locations. We described this issue a few times, including here and here.
New photos indicate a DC current output of up to 615 amps (A) and 1,000 volts (V), which would mean that the new stalls are future-proof for higher power charging. On the other hand, the power electronic cabinets (chargers that power the stalls) appear to be the same 250 kW units (250 kW, 631 A and 0-500 V per stall).
At least for now, the first users report similar power output as in the case of V3 Superchargers, which means that a power increase is not the reason for the switch to V4 in the initial phase.
