Before purchasing a second-hand #battery-#electric #vehicle, every buyer and seller asks themselves how the battery state of health (#SoH) can be determined as precisely as possible.
First services, such as the "Aviloo Device", are already being offered in order to externally check the condition of the battery. But wouldn't it be much more interesting if there was a kind of "digital twin" of this exact battery that automatically saves all the information needed? A kind of "universal protocol" that provides the SoH - regardless of the #manufacturer?
Here is the kicker: Such a "Battery #Twin #Model" could not only store all the important information, but also provides useful tips on how to handle this individual battery in real-time and/or in the future. (1) How to charge, (2) How to use the battery better and even (3) Predict its own service life under certain conditions. Brilliant, if such a thing existed!
Meanwhile, there are countless tips on the internet about the Do's and Don't of battery charging. But even research has not yet been able to provide a universal model that applies to every #cell #chemistry, every cell #format, every #charging #profile, #cooling system and #type of use.
Our guest for today is Dr. Billy Wu. He is a Reader (Associate #Professor) and Director of Research in the #Dyson School of Design Engineering at #Imperial College London. He works in the area of #electrochemical design #engineering.
