They came up with a new charging protocol created using a computer model.
The fast charging curve is the result of the agreement made by the automobile manufacturer and is a means to extend the battery life. In theory, you can maintain the maximum charging speed until the end of charging, but this will damage the battery, so after a certain point, the charging speed will gradually weaken and become quite low as the charging state approaches 100%.
But now, a group of scientists led by Eric Dufek of Idaho National Laboratory has created what it considers to be an improved charging protocol, which can obviously enable the electric vehicle to be charged to 90% quickly in 10 minutes. According to New Scientist.
You can do things like ramp voltage, or reduce the voltage or current in turn.
They used computer models and real world tests to confirm the results, saying that these updated protocols would not affect battery life. These agreements can obviously be applied to any vehicle using lithium ion battery technology, and can be implemented by automobile manufacturers on their existing models.
It is not mentioned whether Duffy and his team have contacted any auto manufacturers that can implement their agreements. But we want to know how a small group of researchers can come up with such a breakthrough when car manufacturers spend billions to achieve fewer goals, and many of them really have the opportunity to obtain artificial intelligence to help design?
We can't help thinking that over time, this may still have an impact on battery health, although we certainly hope to see the implementation and testing of this, if it produces results as good as they say. Charging speed (and waiting time) is an important discussion point in the EV community. Interestingly, they can be improved, not just by upgrading the charger or the vehicle's charging hardware.
