A new charging station cable designed by a Purdue University research team could enable an electric vehicle (EV) battery to be recharged in under five minutes, comparable to filling an average passenger vehicle's fuel tank at a gas station. The patent-pending technology “addresses a better thermal management scheme for EV charging cables based on the principles of subcooled flow boiling. This would enable ultra-fast charging of EVs by the safe passage of much higher electrical currents through the cable,” said V.S. Devahdhanush, a Purdue University Ph.D. candidate and research project team member.
The Purdue team's prototype charging station cable is designed to dissipate heat as electrical current flows through the cable. In comparison to the cable used by Tesla on its Supercharger V3 - currently considered the fastest charger in the U.S. market - the prototype cable delivers 4.68 times the current, according to Devahdhanush. The Tesla V3 supercharging architecture supports peak charging rates up to 250 kW per car.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
