Tesla always strives to improve  customer satisfaction by providing the best possible products, convenience,  and service. Tesla will soon begin mass production of the Semi, so now the company is working on improving the Superchargers that will charge it.

On March 5, 2020, Tesla filed a patent for 'Liquid Cooled Charging Cable and Connector.’ The patent describes an improvement to a liquid-cooled charging cable and charger for charging of electric vehicles, including semi-tractor.

Tesla writes in its patent application:
"The advancement of electric vehicles has created an increased need for charging equipment that delivers electric power. Some such applications (eg, certain fast-charging vehicle chargers) are designed to work with continuous currents of 100 Amps or more. With the advancement of larger electric vehicles, such as semi-tractor electric vehicles, charging duties have increased. Resultantly, charging cables may be required to service charging at 2,000 Amps or more. Higher current flow in a charging cable results in the generation of more heat, which must be removed to prevent overheating and damage to the charging cable. As a result, the conductors of the charging cables have traditionally been sized larger to match higher current draws, resulting in greater bulk, cost, and difficulty in handling."
The patent describes examples of systems and techniques for cooling charging cables. That is, the patent describes a charging system for an electric vehicle. According to the disclosure, the charging system for an electric vehicle can have a power supply, a charging cable, a connector, and a cooling system. The charging cable can have a coolant conduit routed through the charging cable. The charging cable can also have a coolant return path formed within the charging cable jacket. The cooling system can pump coolant through the coolant conduit and coolant return path to remove heat from the charging cable during a charging process.


According to Tesla, production of the Semi will begin in 2021, which means that the charging infrastructure for them needs to be improved. Construction of Giga Texas continues at a rapid pace. It just recently became known that the “First Substantial Completion” should be completed by May 1, 2021. At the moment, it is not known which cars will be produced there, but Cybertruck and Semi are the most likely contenders.
