Dr. Billy Wu: How Charging Routines affect Degradation | Battery Podcast
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.

Great interview, informative and useful. Thanks a lot.
The reality is not as simple as the model. Too complicated model could be misleading in decisions.
This is confusing. Okay, they agree on keeping low SoC but this tesla prof says itâs the %DoD effecting degradation, âmicro-crackingâ of iron oxide crystals within the battery cells occurs much more at full charge-discharge cycles. His advice was to charge less at a time at low maximum SoC to 75% max. Also, I think âplatingâ, when lithium gets lost, he called âdissolutionâ.

Cellphones should have given enough real life experience in battery behaviour
How and where any one can purchase it and the cost of the batteries.
I always trickle charge my Jaguar. BMS goes haywire if it goes under 11,5 volts. So I try to drive it as much as I can since it charges the battery during driving.
Eventually, it will all be wireless charging. Or at least for the most part. You can be 100% sure that Robo Taxi will be wireless charging. There are busses in China which already charge wirelessly at 500 KWh. Also there is very little loss. Perhaps that will improve with technology. SO the weight of the cable shouldn't be a factor for THAT much longer.
I understand the positives of the industry working together but we all know that at the end of the day if that does happen the industry will just find the best cost option and it will not necessarily push for more innovation. Competition creates innovation. Collaboration ultimately creates conspiracy based on history
I want to know about Lead acid batteries :(
Much of the digital battery twin data can is collected by a decent BMS. The voltage of each cell, over current charge, over current discharge, highest voltage cell, lowest voltage cell, back temperature, balancing, etc. So just data log that (lots of BMS units have usart, CAN, Bluetooth, and wifi.
âEVs will get to recharge as fast as gas cars, in a few years!â. NO THEY WILL NOT!!! (not in the next 7-10 years). (Maybe only for long trips, or rushed times, but not all the time, if you do care for the life/cycles of the battery!).
why do european men look and sound so weak and feminine??? must be woke virus
I came back to watch this video again but noticed the negative comment about quantum scape was removed from the older version of this video. I wonder why?

Please explain, when the battery is charged, the cells in it are filled one after another (like communicating vessels), or when charging at 80-90%, some parts of the batteries and cells are not charged at all?
Great guest!

Recap by Tammy AI
Wow, thanks!
Great timing with the timing <3 .
Great episode, thanks! I would love to know how the different cell chemistries should be charged for best cycle life. NMC/NCA should be between 20-80% to prolong the battery life. LFP should be charged to 100% once a week or so. But does it help also to hold it between a specific percentage to prolonged its life or does it not matter as much?

I'd rather just sit in a NIO and let battery swap manage it all, within 4 minutes.....
Who owns the battery in your car? Would you swap you shiny new battery with some unknown battery?
@rjbiker66 until a few days later and you swap it out again? You're worrying over nothing đ Besides, just think of the resale value of an EV, which is 4+ years old where you have zero understanding if its been correctly charged over its lifetime.... the solution? Battery swap.
@@barr96 a few days later someone else has swap their battery with your original.
@@rjbiker66 you're missing the point. You don't own the battery :)
@@barr96 so what happens when you want to sell the car?
This gap was filled at our company starting with the first EV 2008. We for any longer had ICE and even nasty hybrids. But now full fleet of 12 are EV, we also have 11 kWh chargers at office and home and produce much of our own energy giving us FREEDOM from energy Mafia. We usually charge in 10 SECONDS and sit in an already climatized car in the morning. Super Fast charging with my car could be done in 18 minutes at 240 kWh but who cares with a range 70% around the globe never use in one day? We do up to 598 km in summer or 370 miles! So think many concepts where set up by old oil companies with stations only invented by 1925 or 25 years after the car as financial slave systems in fact that always adjusted prices before vacation periods etc. We do not need more HPC but intelligent HOME and DESTINATION chargers. We only go to hotels e.g. offering reserved garages with chargers and enjoy nice trips besides highways with much congestions in Europe. In fact we travel at good average speed and do well to our battery and own LIFE as we can enjoy an absolutely quiet ride in comfort which is unprecedented quality of drive. Most problems are only fake arguments that thinking and flexible people never ever had. when Berta Benz took the car of her husband to visit friends she had no range anxiety, needed no assurance to go 1000 km or 600 miles first and neither needed over 600 hp to claim that the car costs more than a 100 hp combustion car. So we should do everything to change the thinking of people and their prejudices created by bad intentions to follow hidden agendas. Batteries are much better than we think. My BRAUN razor, the first with LiIon has over 25 years and is still fully working and charging. Our Tesla Roadster only needed to change battery as we got an improved version in a special offer which made it a new car with all other things revised and improved. What other car company is doing that other than for some old timers of high value at astronomical prices. The Tesla costed us some 8000 USD and certainly the old battery was still with over 90% good enough for a power wall or so!đđšđ
Great guest. He didn't stumble, need to BS, or get anything wrong technically..... but more importantly, always saw the bigger picture and perspective, and was able to come up with a way to convey it to laymen. So, a great engineering mind, plus a great ability to understand how to explain things to people who are not.
Would like to know which chemistries prefer which charging strategies. Tesla says to charge their LFP packs to 100% but feel it's more so because of the flat voltage and therefore low confidence in predicting the SOC. Are they telling people to lower the pack longevity to improve the consumer experience? ie. flat battery @ 10 % and a tow truck..
I'm inclined to think so, yes. When the LFP batteries were first introduced in 2021, they didn't have the 100% charge recommendations and had a lot of users get stranded at 10% or 5% SOC. They realized that it was a BMS calibration issue where the car wasn't able to accurately predict the bottom of the pack. After a few weeks they introduced the 100% recommendation once per week, which seems like a compromise between battery longevity and BMS calibration accuracy.
I had trouble understanding what she was saying. She would zip through important concepts and I could not recognize the words she was saying, even after replaying.
Oh wait me petrol car has none of these issues lol!!!!!
Well I guess your few of the lucky ones đ€Ł
@@JohnD0129 petrol degradation from charging? Sure.. I am the lucky one

â@@JohnD0129 You are comparing apple and oranges. Battery degradation in comparison with petrol degradation
@@jolly1039 no sir Iâm comparing transportation vehicles in general. Doest matter if itâs Petrol vs EV. All parts degrade over time and are expensive.
I own the battery. I own the data. Digital twin?
See how Tesla is doing it for the semi - enough said.
This is interesting for sure, there are many that hate EV and there are those that love EV and I find that those that hate EV does not understand how a battery works. Understanding is the key in which the tech is getting better by the day so donât give up and keep an open mind.
đ§ excellent đ§ Thanks đ Intro music is Very high & Disturbing...
đNa ion battery đ§ thanks đđšđł
I charge at home with 2 kW power up to 80% capacity. For my casual driving its ok.
I mostly do tthat. If I do it when the sun is shining it is a good match to my average roofttop solar panel output.
For grid applications self-reassembling liquid metal batteries such as Ambri liquid calcium - antimony battery look promising.
9:00 is that the reason why you should keep the charge of a battery between 40-80%?
He's getting all of the little but very important points incorrect.16:00 battery temperature not external ambient temperature is what limits charge performance. As soon as the battery as preconditioned aka heated up to above freezing temperatures It will charge at high speed like normal.
You just have to have the power available in the battery to pre-condition
Great video!!!
Note with the same current and higher voltage batteries the power will increase and faster charging will result.
BATTERY PASSPORT: "A battery passport would keep a record of an individual battery's constituent parts, aiming to increase transparency throughout the supply chain. Information about the battery's raw material provenance, manufacturing, carbon credentials, human rights record, usages and more would be digitally recorded." That doesn't benefit the consumer, this is for politician's control. A better passport would track charging cycles, environment, load application, charging history (abusive?). This information could be developed to provide REAL value to consumers rather than the political bickering built in to the existing passport.
Around 24:30 Dr Wu suggested a choice between accuracy and simplicity. I think that is a false choice. Logs over the life of the battery charging and discharging environment can certainly be maintained. Effort of creating such a system and at what cost is likely the real problem. OEMs don't care once they sell a product. Also, they may be creating a system that could be used against them when it comes to warranty issues. a graph of SoC would be useful to the 2nd hand market. I personally would avoid an EV with high annual mileages. The chances of poor charging habits might increase. Wouldn't a graph showing 20-80% charging and little degradation be more valuable that someone that drives little but charges to 100% frequently? Finally, the unspoken truth -- data is being harvested from every car without the owner's knowledge. So why couldn't more information be available as to a batteries care over it's lifetime?
good arguments! However if the battery_data_Logs were available and/or could be manipulated by the consumer, or with the help of "expert shops", just before a second hand sale!!!, I would be suspicious!
@@konradcomrade4845 - agreed. Data should be immutable and that can be managed with digital signatures.
Is 100% battery always full on battery? I have scooter it says 100% full but when I test it on multimeter it says 82,5 something, if 82,5Ă·20 (it's 20 series system) it gets 4,1 volts the lithium can be full at 4,2 volts?? 2nd another my scooter it's says 97v (23 series system) after got charged at 97v full, it's drop to 96,5 it's 4,19 each it is save for long run? It's already 4 years now and I feel like nothing changed on range it's like brand new
đđ Thanks
Yes I agree with you, the battery of my car, 9 years old, 420.0000 km and 1900 cycles, have a capacity degradation of 12 %, 20 % increase of internal resistance. But with my New victory smart solar charging at home the charging power varying from 1200 to 3500w So I gain 1 % capacity and lower impedance. 120 KW at 5 % soc 7 years ago, now 83 KW at same soc....the BMS do his job..... 45% SUC 55 % slow at home. Thanks tesla. Have a nice dayđ
Very interesting discussion. A thought occurred to me regarding battery degradation. With potholes in our roads multiplying rapidly. The vibration caused by driving a car with an out of balanced wheel will surely impact the integrity of the battery when you consider the sheer number of physical connections in an EV'S battery. Just a thought...
Incredibly unlikely I suppose if you had a wildly out of balance wheel and a poorly latticed battery connections, you might run into some issues. It's definitely not an issue in any Tesla
I know itâs a bit different but I had a iPhone that one day stated 98% battery health to not charging with in a few days
Really use-fall, convinced me EVâs are not ready and I will not get one.
So, my take away is that battery swap will be much easier solution.
Maxell of Japan already commercialized solid state batteries for medical equipment.
Very in and interesting, will check the rest of the series. Someone needs to design a safe add on battery pack to lower the range fears of EV. And FYI my phone battery is useless at 88% of health, but luckily they have battery cases till I can afford a new phone đ
How come 88% health is useless?
@@somutfaydalarpesinde3289 really not, planning on getting one more year out of phone. Then itâs a backup and MP4 player. Thanks ( useless is probably the wrong word, less useful is better )
250 kilowatts is the hard limit for passively cooled cables... If only typical charging speeds were anywhere CLOSE to that number, even 1/2 is good! One of the problems is the shoddy BMS systems being used EVs today. Be it the cooling or the mechanical board being used.
You know this topic is great! Im from the solar installation industry nice insights keep it up! Cheers from philippines.
