Is it just a Hybrid Capacitor? Kind of an odd voltage range, if so...

25% solid state battery aur 75% Namak ki battery

Solid state battery aur Namak ki battery donon sath mein Karon Mein Lagegi

BLAH BLAH BLAH BLAH 😡

The more interesting question is not "does the grid support extremely fast charging?", it's "how much heat do you generate when charging and where do you generate it, does it even make sense to thermally engineer an automotive battery pack that can charge that quickly?"

Northvolt, the big fraud.

Protect this woman. Her tech will disrupt Big electric and big petroleum

Question: will lithium EV battery packs swell with age eventually, regardless of how they are used or stored? Or does this happen only when the battery is not used for a long time?

Interesting to see used EVs starting to be sold in the UK now with State of Health certificates that show the remaining usable capacity compared to the nominal capacity when the EV was new.

This is the best explanation of super capacitoir battery. Although the capacity has improved tremendously but it always lags behind lithium battery but it serves much better in application when charging and discharging speed is crucial. The combination application of both is very interesting. Thank you!

new videos when ? 👀

I think one of your questions wanted more specific detail, of which I would also love expert opinions. Regarding temperature of LFP cells; What is the sweet spot/range of temperature that is best for a cells longevity?. According to the diagram you showed, it seems a sweet spot is 30 - 40 degC. Would you agree? I'm in South Africa (considered warmer than Europe I think) and my cells indoors in summer only reach about 21-22 degC, nevermind winter where they get to about 12 - 18 degC. So I'm wondering if its worth insulating or controlling the temperature of the cells to get closer to 30 degC. I don't charge at high currents at least, but I am trying to get the most lifetime out of these cells.

Price of batteries will still fall the coming 10 years. Zoo cost for batteries will not be the most valuable part.

woohoo people that speak my language, subbed

Nonsense, 800V DC, 500kw chargers are widely available and no need for any cooled cables

Very good but, please, it's equilibrated, not 'equilibriated'.

I need a battery that can perform at -20C to 150C with a voltage curve mostly flat. My circuit runs for 20 minutes at low temperatures. Is there any way to correct this? I fire an actuator at the end of day two at 150 mas. Currently using CR2 batteries from Duracell and other. Failing at low temperatures.

Interesting facts that give a better understanding of how to look after your battery, I've always thought that the reason the charging slows down as the battery gets more charge was because the Potential difference between the power source and the battery was getting closer so it becomes harder to push charge when the Voltage equals out.

Low cost? Why it is very expensive in Alibaba and other online shopping platform. what happened?

Thanks a lot. We are looking forward to see new videos 🖐️

Is it better to discharge a battery from SOC 80% to 20% once or from 65% to 35% twice? Thanks.

As someone dogging the hell out of my EV on ride shares, I'm testing out the theory that consuming energy between 70-30% range leads to less battery degradation (40 kWh on a Model S/about 124 miles usable range before recharging back to 70%) and using a total of 258 miles per day. I'll post the results after 5 years.

Well done India. Best wishes

I have over 10 years old laptop with over 95% SOH battery. I have limited charging to 60%, and starting of charging to 50% unless I need hours of working time. When battery was new, it was bit under 30Wh, and now it's over 27 Wh. I perform couple of times a year a balancing and capacity measurement cycle. Most of time the battery is idling between 50 and 60%. That 10% is enough to move with power on in energy saving mode or work for a while without plugging in. It sometimes goes to under 40%, but charges then only to 60%. The battery experiences full cycle or nearly empty only couple of times a year. Otherwise it's between 40 and 60% soc.

Wake up guys There here Yoshino B4000

Very interesting interview Patrick, I see that you have finally contacted Dr. Wu, since I last saw your interview with Dr. Krupp several months ago. In my opinion, Dr. Wu is an eminence when it comes to batteries, with his simple, direct way and if you doubt, he does not explain how these energy storage devices work, he is a specialist in this field. Thank you for sharing the interview, and it is a joy for me that you met him and made a great video with your guest and your friend who asked you very important questions about it. many successes spreading news about battery development. Greetings from Peru, here there is also an ecological battery model developed by a compatriot from plant pots: it is called ALINTI, which may interest you just out of curiosity. Good luck.

Super interesting interview. We have so much to learn about batteries, energy management and renewables. Kind of exciting times to be honest. 😊

Question Lithium titanate chemistry is know for having up to 20.000 cycle life And verry expensive. Do you consider this type of battery being able to have good return on investment while used in off-grid for home appliances and power for the heatpump and also charging the EV Best Regards Roland

23:56 how about "cold charging" in theory and practise ?

Beside BMS lithium ion can only take what it takes you can’t push cv or cc in each cell

Fast charging creates fractures in batteries. Nothing can be done till they build them different. Good. News they figured it out, bad news: not sure when they will put into mass scale production across all brands.

What should telecom operators in sites areas where there are no public grid?

Technology that isnt safe, should not enter consumer market. Lithium ion batteries are not safe.

Tesla fahren ist besonders effizient😊

Wrap kevlar around those cables to slow down theft.

There can be a lot of variability in battery cells. I bought 2 electric toothbrushes. One battery (Panasonic cells) died after 2 years 1 month. The second one from the same pack is still working after 8 years.

In terms of the issue around large charging cables. Why can't the charging voltage be increased such that there is less current flow reducing the physical size of the cable?

EV Manufacturers should add bigger buffer for EV batteries to avoid getting close to overcharging limits , if battery 100% charge is 4.2V make it 4.12 as maximum charge ,the same at the bottom , when lowest safe is 2.8V make it 2,88V as a lowest voltage .

When will this climate hysteria finally be over and when are we going to return to more sensible energy solutions again?

Wondering about the science about this, and if charging to 100% on an NMC battery(Ford Lightning) is damaging if you are only charging at 12 amps/2.7kW(through an offgrid solar installation). We've cut back to 80% but wonder if we really have to?

When you see the letters 'Dr' and they are not ascribed to a ....ehehe.... G.P. It's time to "listen up".

Sodium ion is better for electric bicycles compared with lithium ion: very low fire risk, robust, longer life, and very quick charge. A small battery size is not a problem unlike a car because you can peddle if charge runs out, you can stop and charge very quickly if you need to, is not damaged if fully discharged, and a small battery size makes the bike cheap.

I don’t know what the professor is saying. Here in Bangalore 95% of autorickshaws are not EVs! The same with bikes/Scooters. Till date I have not seen a Sodium ion battery based vehicles

This is why I'll always stay with ICE vehicles.

As with any commercial interest it's all about money & ultimately control. The investors expect to at least double their money so don't want to develop a technology that you buy once and it lasts a lifetime, they want a technology that you have to renew periodically which increases profit and drives further R&D. I have a calculator made by Casio with a small solar cell and I have never replaced the battery since I bought it new 40 years ago, that was not a great commercial design for calculator or battery manufacturers. Point I am making is you can be damn sure technologies already exist that could give everyone on Earth energy independence that use abundant, sustainable materials like oxygen, hydrogen, silicon, aluminium, iron, calcium, sodium, etc. These technologies can NEVER be released open source as the population would just spiral out of control... and there is the quandary. Only mediocre technologies that can easily be controlled will be allowed to develop.

If an EV were to have a type of odometer- or a log recorder stored in nondestructive / non-resettable memory showing amount of recharge KWH at a +50KW rate, number of KWH discharged while under 20% SOC, and number of hours battery pack spent at 100% SOC (for non iron phosphate packs) , this would give good metrics to amount of wear of tear. Outside of that, a 20 mile drive cycle where amount KHW delivered can be correlated to the percent of charge drop, and then compared to when the pack was new. Example: M3 LR pack is 82KWH/80KWH usable, 1% of charge is 800WH at 75 degrees F when new. A noticeably degraded cell will start delivering less WH per a percent of charge at the same temp.

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 it’s the %DoD effecting degradation, “micro-cracking” 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 “plating”, when lithium gets lost, he called “dissolution”.
