i wonder whether the movement of electrons while charging the battery is correct....I thought we should be forcing the electrons through the negative terminal so that the chemical reaction can be reversed
@RainbowDeath Yes there are chemical reactions that need "extreme" circumstances to start like the heat of a flame. But there is an uncountable number of reactions that work at room temperature and pressure. Like when you add lemonjuice to tea and it changes color or rusting or your cells breathing.
Clarifications: +POS is Lead Oxide, -NEG is Metallic Lead // When Charging, +POS is the Anode and -NEG is the Cathode ... Vice-Versa (as indicated in this video) when Discharging and supplying power to a Load Another Awesome Video!
I appreciate that each video assumes that the viewer knows nothing about electricity. This has really helped me learn by repetition and I don’t have to stop to look up thing. Excellent work!
Agreed. Because of my previous trade in HM Armed Forces, I knew all this but it is still an excellent video, that explains in easy to understand terms, how a car battery works.
Great video again. If you need to jump start a car... make sure the running one is running and connect the jump leads red to red and black / negative as close to the starter as possible on an unpainted surface on the dead car, try starting the dead car, if it starts disconnect the leads. Sometimes you may need to leave it a few minutes before it will start. Once the leads are disconnected you can check the alternator is working with a multimeter across the battery set to DC it should read around 14.4 V when the engine is running.
🤯 oh my God, NOW I see why you're supposed to connect the negative lead to the chassis and _not_ the negative battery terminal! I'd always known not to, but always wondered why.. it's so obvious now. _So the electrons are delivered closer to the starter._ THANK you!
@@nthgth Actually, one reason for this I've seen is so that the final connection is made away from the battery. The battery can release hydrogen gas, which is highly volatile and could be ignited by the arcing during connection/disconnection.
Excellent descriptions, actually. One gripe, when stating/defining the charge of an ion, the symbol is suffix to the number: 2- is charge, -2 is oxidation state. Thus SO4(2-)
This video was absolutely fantastic, answered every question I had on how these batteries worked and your animations made it really easy to understand. I also watch a lot of your other videos and I have to say thank you so much for helping me with learning as much as I can about engineering, I love learning new things but I hate some of the drab and dry videos sometimes uploaded, yours is the perfect mix between showing how it works through your voice and through the animations.
Why haven't the lead acid battery been replaced by the lithium ion battery? The lithium ion battery is better in almost all ways, and is also about the same price and soon even cheaper at under $100 per kWh.
From what I understand, lithium ion batteries don't perform as well as lead acid batteries in the cold, lithium ion batteries don't provide as much amp/hour as lead acid batteries that are the same size, and lithium ion batteries require more electronics to maintain a specific voltage and temperature as they are more reactive.
It's just a generator. The way how applying electricity to a coil makes it into an electromagnet, when you inverse that, the motion of magnets induces current in the wires, and the magnets are connected to a rotor, which, in turn, is connected to the engine via belt. Pretty much all generators generate alternating current (I think all of them, but am not 100% sure...), hence the name, alternator, but the way you can restrict water flow in one direction, but let it flow in the other, the same can be done to electric current, effectively turning it into direct current to charge the battery. Edit: Sorry, there are DC generators too... Key difference is AC generators magnets rotate, and coil is stationary, but in DC generator it's the opposite.
I'm greatly annoyed that industry continues to show automobile current flowing from a positive battery terminal to the various loads when it actually flows from the negative terminal to those loads via the chassis/body structures instead. There is no ground in this situation whatsoever. To say otherwise is to sow confusion. That said, I applaud the channel provider for acknowledging the true flow of current.
A car acid battery works with the principle of Electrolysis. It's a very basic procedure which you all would have studied in your high school chemistry.
Seriously, this was so good. I thought I knew this stuff but whilst watching discovered HUGE areas that I didn't know and / or understand ! Outstanding tutorial - Many thanks.
@5:48 - the "additives" concentration in the negative/anode plate is extremely important. For example, ventless flooded lead acid batteries will have higher concentration of calcium in the anode plate ( lead calcium alloy). The tradeoff for lead calcium alloy battery is quicker sulfation or short battery life inside a car due to charging problems. Some people say the push charge (not float) should be 14.8v but a study suggests 14.1v . Either way, it will have problems in any vehicles. Lead calcium alloy is also cheaper to make.
Tell me about sulfitation. The killer of accumulators. I hate that modern lead-acid accumulators are all of the "maintenance-free" type. I have no possibility to add distilled water, which eventually evaporates even in "sealed" types, especially when they are over-discharged. That should not happen, but can. If you catch the problem fast, you can save an accumulator. If it is of the "maintenance-free" type, you are out of luck if the water level got too low, as you have no means how to add distilled water to the electrolyte.
Remember when checking the electrolyte level in the battery make sure it’s fully charged before adding more. The fluid level will increase while charging and can over flow if not properly done.
@@harshvithlani9399 If youre interested in this sort of stuff watch the video on diodes. It directly relates to what you learn in school and actually did a better job explaining it than my professor. We have a small class so I had my professor play the video to clarify stuff. Ironically my professor would pause the video to explain something, then unpause it just for the video to explain it.
can you please explain how the current flows when jump starting the car? DC runs from negative to positive. we connect the dead battery positive to live battery positive and the live battery negative to the chassis of the dead battery. so, the electrons flow : 1, from live negative -> chassis 2, through the chassis to dead battery negative 3, dead battery positive -> live battery positive is that correct? is that how a car battery gets the electrons when jump starting the car? through the chassis ?
10:56 Might confuse some that Cathode is labeled as positive (Cathode is negative electrode). However in this case the electrode of a battery that releases electrons during discharge is called anode; the electrode that absorbs the electrons is the cathode. The car battery anode is always negative and the cathode positive. This 'appears' to violate the convention as the anode is the terminal into which current flows.
Wait wait wait, I think you might be confusing conventional flow (used only in drawings) and actual electron flow (what actually happens in real life). The anode is negative because it's what initially has the electrons, which have the negative charge. They flow from negative to positive to reach an equilibrium. Or am I misunderstanding something?
this is so great! I remember when I was a school student, I was struggling to understand how chemical reaction and electricity work. but with your video animation it is much easier to understand. student nowadays are really lucky!
Who is this person behind the engineering mindset? This person knows everything engineering. Very helpful and specifically the most helpful videos I found. My go to source.
8:40 didnt like electro boom manage to record electricity in a very high framerate, and the arcs always went from positive to negative, but they could see in very slow speeds that there was very small arcs that went from negative that impacted with the positive arc. Basicly 95% of it went from positive to negative
I do not know anything about a car's battery, but with this video, I feel like I just graduated from Harvard University 🎉 thank you!!! Thank you for the detailed explanation. 🤯
Could you do a deep dive on lithio rechargeable cells? There seems to be different fields of thought around cathode/anode potential labeling, and current flow vs convential flow in general. Your videos are excellent I'm sure it would help clear it up
Firstly you said the grid is coated in a paste of PbO then you said Anode is made of pure Pb and the Cathode is made of PbO, did you mean to say that the grid structure is made from Pb and PbO respectively but then you also said the paste is where the chem. r×n occurs...so my question to you is the only thing that causes the chem. r×n is diff. chemistry of plates(as you later said in the video) so if that is so how this all make any sense? PLEASE respond to my query!🙏 Edit: Also wherever you've mentioned PbO(Lead Oxide) I think you meant PbO2(Lead Dioxide) because when you showed the atoms they were atoms of PbO2...is that so? Anyways, a great detailed video!
We need different materials to cause the chemical reaction. So this battery uses lead and lead oxide as well as a sulfate electrolyte. The animations show the reaction occurring from 10:45
bigger batteries like 200ah ones used to function properly with only 10.5 volts, bc of the size, the starting will draw less current in a size comparison
Never seen a 2/3, 1/4 fire order. Usually they offset each one by a bit. 2-4-3-1, or actually I think mostly it's 2-3-1-4. I'm sure it's a simple design from previous years though. If I were to make it myself, that would allow much easier replacement of the parts involved.
Can someone help with this question If the battery gets recharged while the car is running Why does it run out after a long time like in few years, Shouldn't last forever?
Thanks Paul, informative as always. If the flow of electrons is from the negative terminal then why do car manufacturers place fuses on the positive terminal? Surely they are not providing any protection to the circuit if electrons are flowing out of the negative terminal?
This confused me for a while too. Basically it comes down to which end of the battery or dc electrical power system you decide to define as zero volts ('ground') and also connect this to the metal chassis and engine. If the system has negative grounding then the fuses are connected at the positive supply terminal so that any electrically downstream positive dc wire or equipment which accidentally comes into contact with the large surface area of the chassis will blow the fuse and stop the fault current. It's the opposite way about for a positively grounded system which connects its fuses (or any other type of circuit protection etc.) at the negative supply terminal.
Don't be confused of (+cathodes) and (-anodes) | Cathodes are negatively charged electrodes, that means (+protons) inside cathodes have less electrons, while -Anodes sends more positively charged electrodes (-electrons) that flow's into a conductor (copper wire - free electron structure) and adds more electron particles within the wires when connected to Cathode. Then it creates a reaction that produces electrical energy along with electromagnetic energy. Cathode is sucking all the excess electrons to make it self stable and not to become reactive. When Cathode receives enough electrons, it becomes in a neutral state and is not reactive any longer due to equilibrium. That is why batteries will last.
So if electrons are flowing from the negative how does anything thats connected to the positive and using the car frame as a negative get any electrons?
For all of you Information: A device that generates electricity by chemical reaction is called a battery. A device that stores electricity though chemical reactions is called an accumulator. This is what happens when one lets the technological illiterates define terms.
Because most things are discovered by accident - they are not inventions. Like soap, animal fat dripped on the ashes of the fire below it - and soap was discovered, not invented.
Any idea if I can use a Starlink dish (50-75W) for about 8h connected to my car battery while it charges on solar (200W) at the same time? According to my math this should not decrease the battery power to less than what the car needs to start, correct?
As a retired engineer, while I understand the change in current flow convention, I can't see why that would result in the anode, which has always been the +ve pole, becoming the -ve pole.
Your explanation of charging @ 13:00 was like an "ohhhh I get it" moment for me... as I have been trying to make it "click" in my mind how I can measure amperage both in and out using a shunt only on the negative terminal. I've known that it works, but not necessarily how.
weither the electrons actualy comes from the positive or negitive terminal is easly proven... touch the negitive battery terminal to one end of a light and touch the other end of the light to ground ... and nothing happens.. NOW touch the postive battery terminal to one end of the light and ground off the other end of the light and you get light..we must always question the "authorities" as well
I think there is a small mistake. During charging the Anode and Cathode interchange. Since oxidation and reduction occur in opposite electrodes compared to discharging.
I was actually looking for a comment that helped me understand the relation between what was said in the video and what I was taught = PANIC = Positive Anode, Negative Is Cathode. Thank you!
Fantastic explanation. I just have an issue with the super expensive Fluke 115 meter you recommend in the comments. As an engineer you should know a meter without mA is basically for professional electricians and anyone can get started in electronics with a basic $20 meter (or a $3 from Harbor Freight to cover 90% of needs).
Can I ask you for something? (And sorry, english isnt my language...) In co-operative farm, where I start working, there is "battery room", where are batteries for tractors and trucks recharged. This room is well ventilated. I think about it why, so I asked my colleague. He told me, that its necessary to prevent an explosion, because battery that is recharging is producing hydrogen, that can explode. When I saw this video, I dont see any free hydrogen, so... how? I have never fell in love with chemistry, so maybe I dont see it well, but can anyone explain that to me? Just want to know. Thanks!
It would be fantastic if you could make a video on how car electrical systems work. Particularly explaining how the chassis ground works with the negative terminal of the battery
Even cars with electric motors have lead batteries. No, not to drive the electric motor. But to switch on the high-voltage battery, 12 volt relays are switched on. It would be impractical to operate lamps, speedometer and radio with high voltage. These components are all available as a 12 volt version, and the components that are in other cars can still be used. The 12V lead-acid battery is charged from the high-voltage battery via a voltage converter. But since there is no starter, the lead-acid battery can be small. If the 12 volt battery fails, the electric car will not continue to drive even with a full high-voltage battery.

At 5:56 regarding battery pole. What I know is that The Negative = Cathode and Positive = Anode. Not as you explained. I'm right?

Don't be confused of (+cathodes) and (-anodes) | Cathodes are negatively charged electrodes, that means (+protons) inside cathodes have less electrons, while -Anodes sends more positively charged electrodes (-electrons) that flow's into a conductor (copper wire - free electron structure) and adds more electron particles within the wires when connected to Cathode. Then it creates a reaction that produces electrical energy along with electromagnetic energy.
Cathode is sucking all the excess electrons to make it self stable and not to become reactive.
When Cathode receives enough electrons, it becomes in a neutral state and is not reactive any longer due to equilibrium. That is why batteries will last.
Very good.

The dual functions of the alternator is genius.
Would a frozen battery take charge (at -27 degrees ) if it was at 50% charge capacity when it was left at -27 degrees for a week?

Flows through the frame. It's the same process it just flows the opposite way.

My car has a lithium ion battery I discovered to my dismay when it when flat during lockdown. £600 for a new one.
What are the readon for battery terminal corossion
When it started getting a little complicated I couldn't comprehend how someone could come up with such an invention! 🤯
on the shoulders of giants my friends. like evolution, no one individual has greater value to the end result than do all the participants.
Because most things are discovered by accident - they are not inventions. Like soap, animal fat dripped on the ashes of the fire below it - and soap was discovered, not invented.
trail and error. building up from a simple concept. it takes months maybe even years
👍🏼 Greatest transition & jump to commercial of all time! 🤣 Good video, too! ⚡
Thanks! 😁
Any idea if I can use a Starlink dish (50-75W) for about 8h connected to my car battery while it charges on solar (200W) at the same time? According to my math this should not decrease the battery power to less than what the car needs to start, correct?
As a retired engineer, while I understand the change in current flow convention, I can't see why that would result in the anode, which has always been the +ve pole, becoming the -ve pole.
Your explanation of charging @ 13:00 was like an "ohhhh I get it" moment for me... as I have been trying to make it "click" in my mind how I can measure amperage both in and out using a shunt only on the negative terminal. I've known that it works, but not necessarily how.
Now I undestant How lead acid battery charge and discharge and how its works. Thanks my friend.
weither the electrons actualy comes from the positive or negitive terminal is easly proven... touch the negitive battery terminal to one end of a light and touch the other end of the light to ground ... and nothing happens.. NOW touch the postive battery terminal to one end of the light and ground off the other end of the light and you get light..we must always question the "authorities" as well
amazing
4:39 think flow diagrams are switched
Thank you for putting the flow of electrons in the right direction! It is really not hard to do.
I think there is a small mistake. During charging the Anode and Cathode interchange. Since oxidation and reduction occur in opposite electrodes compared to discharging.
I was actually looking for a comment that helped me understand the relation between what was said in the video and what I was taught = PANIC = Positive Anode, Negative Is Cathode. Thank you!
Fantastic explanation. I just have an issue with the super expensive Fluke 115 meter you recommend in the comments. As an engineer you should know a meter without mA is basically for professional electricians and anyone can get started in electronics with a basic $20 meter (or a $3 from Harbor Freight to cover 90% of needs).
but electrons are not flowing, they are oscillating
Very awesome video
Glad you enjoyed it
SUBSTANTIAL The Engineering Mindset
Tutorial brilliant video amazing thank you
The Engineering Mindset
From Nick Ayivor from London England UK 🇬🇧
Can I ask you for something? (And sorry, english isnt my language...)
In co-operative farm, where I start working, there is "battery room", where are batteries for tractors and trucks recharged. This room is well ventilated. I think about it why, so I asked my colleague.
He told me, that its necessary to prevent an explosion, because battery that is recharging is producing hydrogen, that can explode.
When I saw this video, I dont see any free hydrogen, so... how?
I have never fell in love with chemistry, so maybe I dont see it well, but can anyone explain that to me? Just want to know.
Thanks!
4:29 I hate the so call "Conventional current", it's purposely incorrect and still use for some reason.
It would be fantastic if you could make a video on how car electrical systems work. Particularly explaining how the chassis ground works with the negative terminal of the battery
Even cars with electric motors have lead batteries.
No, not to drive the electric motor. But to switch on the high-voltage battery, 12 volt relays are switched on.
It would be impractical to operate lamps, speedometer and radio with high voltage. These components are all available as a 12 volt version, and the components that are in other cars can still be used. The 12V lead-acid battery is charged from the high-voltage battery via a voltage converter. But since there is no starter, the lead-acid battery can be small. If the 12 volt battery fails, the electric car will not continue to drive even with a full high-voltage battery.
