This tip has been circulating in Tesla user forums and online communities for a few years now, but with the onset of summer it has attracted attention again. Which tells me it’s not fake. Because the old Supercharger V2 charging panel does not have a cooling cable. that when summer sunlight reaches the handle (To connect the charger to the car) it has a higher temperature. Until the sensor sends a signal telling the charger to reduce the charging speed to keep the temperature at a safe level. Therefore, when a damp cloth is placed on the handle It will help block sunlight and reduce the temperature. and results in faster charging speed or faster charging.
One Tesla owner revealed that he used this technique on a hot day with his Supercharger V2, which increased the charging speed from 60 kilowatts to 95 kilowatts. Many other owners have also joined the Out of Spec Studios online community.
The data reveals that owners of these vehicles connected the charger at a 2% state of charge and the Supercharger increased the charging rate to 147 kilowatts, but subsequently overheated, causing the charging rate to drop to 58 kilowatts with a charge of 34%. then placing a damp cloth on the charging pole holder brought the charging speed back to 119 kilowatts.
Another extreme test of the compressor with wet rags. Connected to 2% SoC: increased up to 147 kW normally and thermally limited to 34% up to 58 kW. I slapped on the wet rag at room temperature and it went back up to 119kW where it reached the limit of the internal charging profile. Amazing! ⚡️ pic.twitter.com/0o6VGgdhc9

This trick doesn’t apply to the new Supercharger V3 charging panel, which charges most Tesla electric vehicles. With the exception of the Cybertruck electric pickup, which is equipped with an 800V battery pack (other models have 400V), every Supercharger stations in the United States. Impossible to supply 800 volt electricity
The Tesla Cybertruck has two 400 volt battery packs connected to 800 volts, but when charging there is a switch to connect the 2 batteries in parallel at 400 volts to match. Compressors The charging current increased to over 700A, causing the charger handle to overheat, which cannot be removed even if heat dissipation was applied. And using a wet cloth can help charge the Cybertruck.
Additionally, longtime electric car racer Branden Flasch has been posting about other people’s cars as well
However, this trick, regardless of the Supercharger model, will help recharge it a little faster. But when the state of charge approaches 100%, the charging rate will still decrease. So it’s nothing special. But keep in mind that these techniques are not authorized by the company. Therefore, car owners must accept it at their own risk. But some say Compressors It can be loaded safely while it rains So just a damp cloth should not cause any harm.
Finally, it is recommended for safety reasons. You should first wait for the charging status on the car screen or smartphone app to complete. Then gently pull the charger handle out of the car.
