Experimental cable charges electric vehicle in 5 minutes

A new study was conducted by experts from the American Purdue University: their development will help reduce

the amount of time it takes to recover energy from an electric vehicle.

The new device uses alternative cooling technology to dissipate heat from the charging cable. In this way, the current required to charge an electric vehicle can be conducted in less than five minutes.

During the work, the authors focused onpower cable, since it is its configuration that is responsible for the charging speed. Modern solutions are based on liquid cooling systems, similar to what is used in computers to prevent overheating. But these systems cannot be greatly expanded in order to increase the amount of current and speed up charging. In this case, the cable will seriously increase in size.

In the course of experiments, the authors managed to developa prototype cable based on liquid vapor cooling. The heat generated within it converts the liquid into vapor, which is then circulated, cooled and converted back to liquid form, and then passed through the system again.

As a result, the new approach makes it possible to processmore heat than existing counterparts that are already operating at charging stations. The new prototype can handle more than 2,400 amperes. That's 1,000 amps more than needed to cut an electric vehicle's charge to five minutes, and more than 4.6 times more than existing chargers.
