Recently, in an externally published patent application, Tesla gave a potential solution. According to the method proposed by the scheme, the Tesla charging station can realize high-speed charging and automatic charging in the future.
The first thing to note is that sometimes the patented technology applied by each company may not necessarily be converted into commercial use. Therefore, this patented technology of Tesla cannot be too optimistic. Instead, this new technology from Tesla should be viewed from another perspective and is only seen as an interesting patent.
For this charging technology, Tesla first filed a patent application in 2014 and updated the application content in the following 2016. At the beginning of this month, the patent application was finally formally disclosed. The name of this patented technology is: "Thermal regulation provided by the charging station during the charging process of the electric vehicle". The patented content describes a ground-mounted system that automatically charges the battery of an electric vehicle with an external cooling system that enables an efficient and fast charging process.
The following are some of the important sketches and schematics of the system given in the patent application.
According to reports, the physical shape of this charging system is similar to the wireless inductive charging scheme, but it is a wired connection. Therefore it has a relatively high charging efficiency.
Tesla also describes how this thermal regulation state works in the patent document: the initial signal from the electric vehicle to the charging station is sent via a wireless communication connection (eg Bluetooth) and the electric vehicle is realized by this connection. Pairing with the charging station. In response, a suitable electric vehicle charger connection will be determined accordingly. Included for the connection for charging (in some cases, a dynamic flow connection to achieve a thermal state adjustment during charging). A temperature demand signal or any other form of thermal information will then be sent to the charging station via the signal line in the charger.
In the case of DC charging, the battery will be hot, so this new charging system is equipped with a higher power electric vehicle battery external cooling system to achieve higher charging rate capability. As Tesla CEO Elon Musk has hinted, the future Tesla Super Charging Station version3 will achieve more than 350kW of charging power.
This charging station also has a disadvantage: this ground-mounted charging system adds to its complexity compared to Tesla's previously introduced charging solution "machine snake charger".
