How to quickly charge a Tesla in the hot summer? One piece of cloth solves it!

News on May 8, as the temperature gradually rises in summer, the charging speed of electric vehicles has also been affected to a certain extent. At the same time, some Tesla owners have discovered a simple and practical way to increase the charging speed of Supercharger stations, which is to cover the charging line with a wet towel while charging.

This little trick has been circulating in the Tesla owner community for a long time. With the arrival of summer, this practice has attracted more attention from car owners. The principle is to use a wet towel to block direct sunlight and reduce the temperature of the charging cable handle. On older V2 Superchargers, the handle heats up quickly after being exposed to sunlight due to the lack of active cooling of the cable. The internal sensor will therefore instruct the charger to reduce the charging speed to maintain a safe temperature range.

In the experiment, the data editor found that in hot weather, the charging rate of the V2 Super Charger was significantly improved after using a wet cloth to cover the charging cable. For example, one owner recorded an increase in charging rate from 60 kilowatts to 95 kilowatts. There are also car owners who plug in the charger when the battery power is low, and the initial charging rate quickly rises to 147 kilowatts, but as the power increases and overheating problems occur, the rate drops to 358 kilowatts. Then, after placing a wet towel, the charging rate jumped back up to 119 kilowatts.

Regarding the new V3 charging pile, this trick is not effective for most Tesla electric vehicles. The only exception is Tesla’s electric pickup truck Cybertruck. This car is Tesla's first model equipped with an 800V battery system (other models are 400V systems). While former US Superchargers were unable to provide 800V power, the Cybertruck increases charging current speeds by splitting the battery pack into two 400V sub-units. In this case, the wet towel trick may help Cybertruck owners increase charging speeds when using V3 chargers.

Although this solution can improve the rechargeable battery experience to a certain extent, it is not absolute. When the battery is close to full charge, the charging rate will still decrease. In addition, regarding safety issues, car owners generally believe that this method is safe, because Tesla’s Super Charger can work normally on rainy days, so wet towels will not have an adverse effect on the charging process.

This little trick provides Tesla owners with a simple and practical way to increase charging speed during hot summer days. While the results may vary depending on the car model and charging plug type, it's certainly a method worth trying for those car owners who want to charge quickly in a short period of time.
