Yo what's up I'm now sitting in an mg4 51 kilowatt Hour lfp battery and in this video I'm Going to talk about well lfp batteries Versus the Cobalt batteries So uh yeah uh I just finished that run Which is the Steep Hill test and it was Very interesting and quite surprising How this car performs So oh you'll be like oh how was it how Was it well if you want to know how it Was you have to wait a couple of days And then you can watch the video and see What happened yeah so um yeah but okay In this video I haven't had any of these Uh rambling videos in a while now so uh It was actually based on a A Thai follower or actually Frank they They call it FC fan club he asked me During a live stream like hey Bjorn uh Or hey yeah uh what is the difference Between lfp battery and uh and the and And nmc battery or the the Cobalt based Batteries and I was like well Um And I started explaining you know so Wait can we turn right because it seems Like it's kind of hard to turn right now Because of the traffic is quite massive Trafficking yeah but so uh where do we Start lfp it's like this car has it Means uh lithium iron phosphate It doesn't have Cobalt in it and then The the one with a bigger battery the
One the one the in Europe you get the 64 Kilowatt hour Um mg4 that one has Cobalt in it okay Let's go Sorry I had to focus I'm driving let's Just Hammer this guy Okay And then Cobalt is like it's like the Steroids for Batteries Cobalt will boost Its uh its properties to make it better For example when the when batteries are Cold typically uh they will perform Worse they will have limited power Output uh in order to not damage the Battery And also they will charge slower but Then when you add Cobalt to the battery It makes it better it can then charge Faster or discharge more And then lfp since it doesn't have Cobalt it will also kind of suffer from It So LFE battery is kind of they actually And if lfp batteries will perform best If they are heated up and in Thailand The lfp battery makes perfect sense in Thailand because it's in general fairly Warm over here So I've noticed in uh car scan or test Scan my Tesla that during a typical Drive in Thailand the battery will Actually stay at around 30 to almost 50 degrees Celsius yeah but That was Tesla Tesla might feed the
Battery yeah I think Tesla is actually Feeding the battery with heat from from The motors the heat Scavenging some kind Of alien Technologies some Advanced Yeah and then leave while Leaf goes to 56 degrees Celsius well that's a Different story but okay so that's at Least the differences there and then an Nmc batteries NCM NCM batteries I think it's a nickel Cobalt manganese I think that's the one That one Uh it's it's more energy dense so that's The that's you know that's why the Bigger battery is there in the Cobalt Battery because it's it has higher watt Hour per uh kilogram uh so you will find A high capacity uh cars to have uh Cobalt batteries for natural reasons but Yeah I also I think it was weight yeah You have volume versus weight also so The the Cobalt batteries are you in general you Know smaller and lighter which is very Crucial for uh cars like EVS but on the Other hand if you don't need that much Capacity nowadays you the batteries are Getting better and better so in this Battery here 51 kilowatt hour and the Car weighs 1 750 kilograms it's actually Not that bad you know And you still get uh over 300 kilometers Of range on this car so and it could Have been better if the car was more
Efficient even but yeah and then another Thing is that The Cobalt batteries they are more Expensive than the lfp batteries in in Terms of kilowatt hour or you know what Hours so That's probably why Chinese car Manufacture they start using more and More lfp batteries because they are Affordable and you know the low the low Range cars like this one is going to Then be cheaper Another Difference is that The nmc battery you know you heard it Like all batteries are dangerous once it Catches fire you cannot extinguish it Which is kind of true uh and then if the Battery gets too hot you get the thermal Runway and if you puncture the battery It would just catch fire and yeah and Burn in a very uh scary way That's that's for the Cobalt batteries But lfp batteries they are way way way Safer I think I haven't tried it myself But I think you can you can actually Puncture the battery and it will still Not catch fire you know And I don't know how many degrees Celsius it can actually take Without Catching Fire so LLP way way Safer Another thing is that um you know Batteries they have a voltage and then
When you discharge the battery the Voltage will drop and then when you Charge it up the voltage will go up I Don't remember exactly uh yeah and the Cobalt batteries the common Environmentally different environments Like like in the in this car you have The the NCAA you know and NCM button Tesla uses NCA which is the a is Aluminum instead of uh manganese right And then I don't remember other variants Again But um Wait what was my point again yeah Voltage voltage so so typically one cell Is a nominal voltage is 3.7 oh Okay 3.7 volts but when you discharge it To the low I think you can distort it as low as 2.5 Volt Maybe it's not recommended but yeah Roughly there right and then when you Charge it up to maximum it's 4.2 volt Roughly But yeah it also depends on chemistry And all that and then how you mix the Cameras in but roughly there but the lfp Batteries the voltage range is way way Narrower so when you discharge the Battery to almost zero right it's I Don't remember how much it is but it's It's way way narrower narrower Um voltage span and that actually makes It slightly harder to estimate how many
Percent the battery is at and then and Also how to calibrate everything uh Right because I mean how how can how can The cars tell you that you have like now 43 battery well it looks at the voltage To figure out How much it has so That's probably why maybe some car Manufacturers they don't want to use LLP Batteries because it's harder to to Figure out how many percent you have but Then for for some some devices uh let's Say uh A lamp or something right or something Not critical then it's not too important That we we get very accurate uh reading You can just say well it's roughly 70 Roughly 80 no big deal right but for a Car you kind of need to have very Accurate uh Measurement on how much energy or Battery you have left Okay what else differences uh well so The Cobalt batteries they contain Cobalt And the Cobalt comes mainly from Congo Wait what the what's up with the Traffic over here man uh and then Congo Is okay I don't know too much about it They just heard that the political Situation in Congo is kind of unstable Um and then uh supposedly the the The Cobalt comes from the mines that it Has been mined by child slaves so if you Want to criticize EVS for being bad
You know you can just say well it's um It's it's from you get the wrong like You you are you are on your high horse In your EV thinking that you are saving The planet but The minerals for your EV comes from uh The bare hands of a child slave in Africa which is a country right I'm just Kidding what dude this damn right lane Huggers dude oh man yeah Yeah these these pickup trucks by the Way I don't know if you can see it but They have modified the suspension so That they can load way more than uh the The cars uh original design is But then it means that the car becomes Very very stiff And they then typically in Thailand you You have a very shitty Or poor maintenance on the roads and Then the the left lane which the trucks Mainly Hammer at They are quite bumpy so the so the these Kind of pickup trucks they they then Always hug the right lane yeah and they Don't give a I I also tend to hug The right lane because I don't want to Ruin my rims but if I see traffic coming From behind fast I will just move over To the left lane let them pass and then Move over again but these guys They don't give a okay anyway But LFE battery has another nice
Property which is that It has way way better degradation so When it comes to degradation Um it's bad for the battery to be Charged to 100 percent And it's bad for the battery to to stay Warm Um If you keep it if you keep those two Conditions The longer you stay there than the words This means that you can if you just Briefly charge it 100 and then you start Discharging it again Uh and even if it's hot no big deal it's Not that much but if you Leave it at 100 in Bangkok where it's Hot and leave it there for days then That's bad for the battery but for the Cobalt battery For lfp battery lfp batteries they can Take the heat way better and they also They they don't care too much if they Are charged 100 percent So uh typically uh LFE budgets they will Have like two three four times higher Cycle uh lifetime than Cobalt batteries So it's simply amazing how How well lfp but you know simply Speaking of simply amazing which is the Nissan slogan for the the new the Branch Banking New Leaf that came out the 40 Kilowatt hour Leaf the leaf should have Used lfp battery since Leaf doesn't have
A thermal management then they could Actually just punish the battery and Even at 55 degrees Celsius they could Probably still take okay charging rates With it but I think the problem with Leaf is that maybe the energy density is Too low because I need to overtake these Slow pokes okay so it's actually very Common to Kind of overtake with okay I'm still coming through coming through Yeah I mean it looks dangerous but we Have plenty of space here and it's yeah That guy also when he blinks at me the Thai people they just blink at you for And it really typically in Norway if you Want to talk you want to cross the road Like you you want to take a left turn Right and oncoming traffic is flashing At you A couple of times it means go ahead you Know I will wait for you in Thailand if They flash at you it means stay there Don't move I'm gonna go first yeah And also in Thailand When you when you um want to in like a Like um like a queuing situation or or Like a sip merge right or if you just Want to change lane and you want to get In front of someone don't ever ever ever Put on the turn signal And wait for uh for them to give you a Slot they will then accelerate like this And close the gap and block you from
Entering uh yeah so what you need to do Is find out if you have enough space And then you just slide it in like a Ninja Yeah maybe blink once yeah like a true BMW driver yeah but okay back to back to The lfp again so what else is it yeah so But but okay so I mentioned by the way The lfp doesn't like the cold weather it Actually performs quite poorly if if an Lfp and a Cobalt battery they are both At 10 degrees Celsius the lfp will have Way lower discharge rate and way lower Charging rate than in Cobalt battery Remember that I told you that Cobalt is Like the steroids for Batteries it makes Everything better Uh but Well-designed cars like Tesla they can Overcome that problem because when You're driving you will have typically You have leftover heat from the motor Because the motor is not running at 100 Efficiency that would be simply amazing Uh so there will always be some leftover Heat and then with heat Scavenging you Can then divert heat into the battery Instead and that's what Tesla is doing In the beginning lots of Tesla owners Were complaining that was many many Years ago they were complaining that the Batteries The lfp batteries that were Performing poorly in cold weather
But Tesla fixed that by Actively heating up the battery and Especially at low state of charge Because that's also another condition When when you have low standard charge You can then not get the same power Output as if you are at higher stable Charge So Tesla actively towards the end when The state of charge drops towards 10 Percent it will heat up the battery and Keep it at higher temperature than when It's uh higher standard charge so Tesla Is doing some smart engineering to Overcome or mitigate the problem with The lfp batteries but then what about This mg so the CV when we drive it to Yellow in Winter and it's minus 10 Degrees Celsius will it then charge fast Oh and another another thing that Tesla Is doing and then more and more car Manufacturers doing is that when you Navigate to a fast charger the car will Automatically preheat the battery heat It up uh actively so that you can Receive uh faster charging speeds but uh Like Cobalt batteries like uh like uh Like the Korean cars for example right Uh they don't need to be that hot to be Able to uh take good charging rates I Remember when I tested I think was in Euro which is Cobalt based battery uh Even when their battery was only 10 Degrees or 5 degrees Celsius it was
Still taking over 50 kilowatt but lfp Battery at those temperatures might take Only five kilowatt you know What else is it with lfp versus Um Cobalt batteries hmm Yeah I think I I cover most of it so um Yeah I find it interesting and also Which type do I like the most well Actually I I like lft better and better Because okay I mentioned that the the Energy density is not that great for lfp Battery but you know a battery pack Consists of maybe hundreds or maybe Thousands of smaller cells and then each Cell Uh is then packed together Arranged in zokana Array and then maybe Put in parallel put in cereal to get the The whoa that was attraction control but So you can have higher voltage and then Higher capacity But then they also have to bundle it in Modules And all that packaging and all that Stuff actually adds some overhead and The effective energy density then Becomes lower so Tesla is doing Something smart they're making the fat Cells which is bigger bigger cells with Bit more volume and then you have lower Waste of material In between right and stuff like that Packaging And therefore uh uh I think the Tesla is
Trying to reduce or actually eventually Eliminate the use of cobalt and they Have to figure out something so they're Doing that one to to still have a high Okay I might have to talk to that guy by The way he's gonna ask me where do you Go Yeah there are plenty of these police Checkpoints they are looking for illegal Immigrants from Burma or from Myanmar Okay I need to overtake that truck Because he's not going very fast Um so we're gonna do the like a Thai Thai style Um which is to hammer it on the Continuous line and I I know it's not Legal but everyone in the mother is Doing it you know like like Germans they Go 20 kilometers per hour over the speed Limit yeah because everyone is doing it No but um but also test Tesla is not the Only car manufacturing car manufacturer Doing something smart with the battery Packs uh byd with the blade batteries oh Look at that look at that body roll No but byd they also Have the blade batteries you know so Typically if it's a pouch cell or um or A prismatic cell each cell where I have To focus here a little bit okay but I'm Just going to do it barely legal here Okay okay Forgive me Father I have sinned I have Hammered okay but
Um like like a like a pout cell is Roughly this the size of my palm you Couldn't we could have called it the Palm cell almost to think about this a Car battery is huge so it needs to Consist of many of these pouch cells but Byd they made the blade battery and then Instead of having smaller cells they Have a huge law very long lfp cell uh I Think it's like one meter long that's Why they call it the blade battery right And by doing that they also reduce the Waste Material in between and so on and they Talk about cell to pack uh well I'm not Sure if that was the byd or whatever Instead of having modules several Modules they just have like the cell Right into that consists that goes that Becomes a battery pack without having to Have more segmentation And that means that the effective Energy density and the feed battery will Be higher by designing the battery pack Smarter so even though the lfp has low Energy entity it doesn't have to be that Bad really so that that's actually very Uh very good because in my opinion we Should actually try to avoid using um Cobalt in the batteries right unless There is a way to find Cobalt somewhere Like from an asteroid or some yeah But okay so I think I covered uh most of It now the differences between
Um lfp and NCM and Well okay I can say is that for cars Then yeah LFE batteries they have the Disadvantages because they are kind of Heavy and all that but there are places Where lfp battery wouldn't matter too Much for example if you have local Storage like some kind of in a in a Solar PV system When it's stationary on the ground in a House or in a in an industrial building Then you don't care how heavy or big it Is so their lfp would make perfect sense Because it has a perfect a really great Lifetime and everything right So Um But I guess if you want the big the best Range then you still have to go for NTM I mean or the I mean the Cobalt Batteries but I'm actually liking it at A fee more and more now So um yeah and then I want to ask you Guys which battery type is your favorite Okay anyway I think that's going to be It for now I hope you guys enjoyed this Video as always thank you for watching And talk to you later
Electric City Vehicles Cars Power


Electric City Vehicles Cars Power
Electric city vehicles cars power are a great way to reduce your carbon footprint and improve the quality of your life. They also provide unique benefits that gas powered vehicles do not have.
The first benefit is that EVs are not very energy intensive. Electric cars are quiet at low speeds and do not emit emissions. However, they do have limited range. That means they do not go as far as a gas-powered car, especially when driving at a constant speed.
Another advantage is that you can charge your vehicle overnight at home or work. Some EVs are capable of traveling up to 80 miles on a single charge. But that may not be enough for long distance travel.
If you plan to drive long distances, it is important to plan a large buffer between the EPA combined rating for your EV and its actual range. For example, a Porsche Taycan has a city range of 257 miles, while a Honda Civic Hybrid has a highway range of 250 miles.
While there are many different types of electric vehicles, the majority can cover about 80 miles on a single charge. In addition, battery-powered EVs do not require oil changes or tune-ups.
Aside from these advantages, electric vehicles offer convenience. Many can be charged at home, or in multi-family housing. This also helps with fuel savings. There are also public charging stations.
Depending on the model, your electric car can take anywhere from two to three hours to fully recharge. However, the time will decrease as technology advances.
