From a scientific standpoint, the largest challenge facing today's electric cars is the energy density of batteries used. The batteries are both massive and heavy, and as a result have significant impacts on electric transportation feasibility depending on the scenario. This video analyzes today's batteries energy density, as well as the efficiency differences associated between gasoline vehicles and electric vehicles. Even when accounting for efficiency, the gap between electric and gasoline energy densities is quite large.
To further illustrate this point, we'll assess the feasibility of an electric powered semi-truck, and the weight of the battery required in order for the vehicle to have a range of 500 miles. The results will SHOCK you. Maybe not; that's just a bad joke. But you might learn something! Have a watch.

    You know it's interesting what people don't even realize is that the current car you're driving right now has an ion engine in it it's called a catalytic converter a catalytic converter through a catalyst process converts the combustible hydrocarbons and exhaust from your engine and causes a catalyst between the minerals in the converter that converts them into less dangerous emissions two of those chiefly are heat and water so you already have an ion engine in your car call the catalytic converter now what if they figure out a process or way to power the car on a larger device or catalytic converter where you have an engine like a catalytic converter that is able to take water or hydrogen or some other fuel source and through a catalyst process creates and generates Heat which is energy and then that is then used to power the car or vehicle people don't even realize you already have a mini ion engine in your car and didn't even know it it's called your catalytic converter that's what I mean about evolutionary steps forward in technology think about it what if they could develop a catalyst material that was far more reactive and say it reacted to something as simple as water or air or oxygen or some other element and created so much heat and energy that that could then be harnessed to actually power the vehicle I think that technology is just around the corner

    It could be a fuel cell technology or perhaps ion engines NASA as we speak is working on and is developing ion engines that run on plasma so one day in the future you may have a vehicle that runs on an ion engine that is able to convert just air into plasma and energy through a catalyst process that will power your car vehicle almost indefinitely I don't know I'm not smart enough to know what the evolutionary leap will be but I am smart enough to know that it will happen and it will happen before this century is over because I study technology I studied history and I know how these things go and I can tell you that what everybody thinks is the future is not actually what the future wants a bean where are my flying cars lol you see we were all promised flying cars by the 2000s and so where is my flying car LOL see what I mean about technology in the future it rarely ever is what they tell you it's going to be

    We are due for an evolutionary leap remember technology must like Evolution does not drudge along inch by inch it makes giant leaps forward that catch Everyone by surprise we didn't learn how to harness lightning for energy to Electrify our cities we just learn how to create electricity for ourselves and I am telling you right now electric vehicles and electric trucks are not the future the future of powering cars and vehicles will probably resemble something on the level of a fuel cell. I don't know if it'll be hydrogen because there are issues with hydrogen it may be some form of nuclear fusion we don't even know yet what science will bring this but there will be something that comes along in this Century that will solve all of our energy problems and all of this will seem really silly and your great-grandchildren will be watching NOlocal videos about when everybody thought that everyone was going to drive electric cars I suspect that the technology will be some kind of a fuel cell technology and will most likely be on a nano level as I think that nanotechnology is the future some kind of a nano fuel cell technology that will have nearly Infinite Energy producing capability and will make gasoline obsolete will make batteries obsolete will make all of this obsolete that is the evolutionary leap that we need to make to solve our energy problems because remember an electrified vehicle does not solve our energy problem something to think about

    Everyone forgets that Lithium is a heavy metal, dangerous to human beings, electric cars catch fire, toxic fumes worse than IC vehicles, but worse still it produces more carbon pollution (the god of greenies) to produce car batteries than IC engines AND when they are knackered and need replacing they are expensive to replace YOU pay for the exhausted batteries to be returned to the country of origin and stored. With IC engines most of the vehicle is recyclable and of value. Lithium Ion Batteries are a liability when they become useless. The Agenda Driven pro electric devotees hide these facts to support their beliefs. I live in Australia, I go 500km to my nearest holiday destination, 2000km east to leave my state or 4500 km north to do the same guess which vehicle is the only option available to me. Yes, not a vehicle with a max range of 300km with an 8 hr charge.

    That not really true. While that argument it is true for gas vs (soon obsolete in 2021) battery technology at the making of this video. It does not account for the inefficiency internal combustion engine of extracting that energy. To extract the energy of one gallon if gas you need 5 gallons of gas as engines are only about 20% (diecel engine 30%) efficient. As where electric engines are over 90% efficient in energy extraction.

    When talking about EV's, the presumption about their success in the future all points to increasing the efficiency of batteries. A lot. Never a doubt that such improvements are even possible. There are limits of physics, right? E.g., ICE vehicles have improved, and continue to improve, but nowhere near the rate of improvement as they did in the past. Now the improvements are very small, and by using evermore exotic and complex technologies to make it happen. Same is happening with solar panels and wind turbines: the improvements were great in the early stages of development, but now the improvements are increasingly fine and small. And I recall Mercedes dismissing Elon Musk's claims of battery development, stating limits of physics.

    Why is not efficient having a combustion engine installed on a car producing electricity (not car traction) for an electric engine doing the car transportation? I assume that the combustion engine will be more efficient as a electricity producer than a traction engine (less gear box, power distribution, etc) while an electric power train will be more simple (as moving parts).

    Hey; I like your Videos but sometimes you forget major components of the equation; in this particular case you've forgotten to factor how we produce electricity in the USA which is required to charge the all electric cars in the first place. While California leads the nation by producing about 15% of its needs by wind and solar; which are very efficient; nation wide those sources only account for 2% of the power you use to charge your electric cars. About 90% of electricity in the USA is produced by burning natural gas and other fuels and the best of these are only 60% efficient. To compound this problem; transmission of the power from the plant to the charging station can lose as much as 20% of the electric power produced; and you can lose even more while charging your all electric battery pack. So overall with the current means of electrical production you basically have no significant advantage over a gasoline cars ; let alone a Hybrid car in terms of energy efficiency. This can change only if electrical power is produced by highly efficient solar, wind; nuclear, geothermal or similar source. Even California will have to increase its wind/solar by 7x just to meet current electrical demand and the added demands of an all EV fleet would make it more like 15-20x. For the nation as a whole we are talking 45x. This figure could be moderated by more efficient solar but few believe you can do better than 50% efficiency. But lets say you have your own solar cells and charge your own car with 100% solar. Well; even then you have to look at the following equation. Force = Mass * acceleration squared F=MA^2 this is a major law of physics. If we presume you are a typical driver and you'd accelerate your car the same way and not try to become a race driver because you think your EV is efficient - we can cancel out the effect of how fast you accelerate on your drives. This leaves MASS as the factor which will change between types of cars. So if a Tesla Model S is 5000 lbs and a Model 3 is 4000 lbs; If say a Toyota Prius is 2900 lbs and is part electric plug in; you gain little if anything from the highly efficient electric motor because your car weights a great deal more. An all gas car could easily be 2500 lbs so it can be half as efficient in terms of its engine and still burn no more fuel per mile. This is why it is paramount to reduce the weight of EV cars. Now you can say a Non EV may well burn fossil fuels to do that and produce pollution but pollution and efficiency are two different topics. However; since we are mentioning pollution - a much large electrical grid suggests MUCH greater use of Sulfur hexafluoride a green house gas 25,000 times more potent than CO2; and since this gas stays in the atmosphere 16 times longer than CO2 it represents a potential negative overall environmentally to move to go to EVs. Lastly as noted in one of your previous videos; higher weight suggests higher production energy costs and thus an energy deficit before you even drive the car one mile. The best hope for EVs to become the dream people want them to be is to reduce their weight by at least 50% and slowly replace existing electrical production with a Non SF6 dependent electrical grid.

    35-40% efficiency for a pure-gasoline power train is very optimistic. Yes, my Prius Prime’s engine does indeed have a peak thermal efficiency of 40%, and that is indexed quite impressive. However, *a pure-gasoline power train hardly ever lets the engine operate at peak efficiency* . All told, it’s still hard to get better 25-30ish%. A hybrid power train can keep the ICE off completely until it is able to run at close to peak efficiency, but its still not perfect.

    There's a couple of things that no one ever talks about with regard to electric cars. 1> Where does that electricity come from to power electric cars. More often than not from the burning of fossil fuels. So one needs factor the initial efficiency of electrical generation to charge these cars into the equation. 2> The reduction of revenue from fuel tax for the construction and maintenance of highway infrastructure. The government wants us to drive more fuel efficient cars, but they never stop to consider the reduction in tax revenue that necessarily causes. As a result the rest of us who drive gas cars end up subsidizing electric/hybrid drivers in the way of higher gas taxes. A few states are considering surcharges on electric vehicles every year as part of their vehicle registration.

    Totally agree with the assessment based on an individual vehicle. I do wonder if the drawbacks of an individual vehicle can be minimized by owning a fleet of these, up to a point where it makes a vehicle viable for logistical use under right conditions. It is clear from that video that long distance freighting is not viable, at least for the moment. A network of distribution points may be a more efficient model to use an electric truck in. The trucks themselves could have interconnectivity between individual vehicles and maybe in some future even autonomous driving. To further increase the efficiency of the model, one could invest in digitization of the office. This would make planning and general administration more efficient. Digitization will also allow different logistics companies to digitally share vehicles, trailers and container space. Maybe an idea for a follow up video? "At present day, could a logistical model be created and maintained that would make a current day electric truck viable?"

    Many issues start disappearing if you raise power density from 250 wh/kg to 400 wh/kg , which is perfectly possible with nearish-term improvements, and keep striving for high efficiency to reduce heating issues. The other solution that European manufacturers have been pushing for is... pantographs. Stone-age tech I know, but electrifying the interstates would almost completely eliminate the range requirement issues for trucks, at the cost of some infrastructure requirements.

    ICE Cars biggest problem is that practically all the potential efficiency has already been squeezed out of their powertrains, which is rarely ever above 25-30% (well-to-wheels) overall. The most significant gain in ICE vehicle efficiency over the last decade has been coming up with more & better ways of turning the ICE OFF. Going forward, improvements in ICE efficiency will be so very slight as to end up being almost pointless, compared to BEV powertain efficiency that's already available and the larger gains in battery energy density that will start showing up in production BEVs over the course of this decade. As for the charging infrastructure... connections to the electric grid are already available in 1000x more locations than gas stations, and millions of times more than non-starters like hydrogen (the experience with CNG vehicles effectively proves that). The handwriting is on the wall: BEVs will dominate the personal passenger vehicle & light truck markets by the end of this decade.

    Forget about "regular" gasoline or batteries! Nothing beats Diesels when it comes to Efficiency and Fuel Economy! Change my mind!

    Would love to see something around the efficiency of diesel electric railroad power (the original “production” hybrids) and the feasibility of using similar technology in highway transports.

    I think battery technology will be short lived in cars. They make excellent fuel sources for power tools but that's about it. The problem with batteries is the exhaust. Batteries carry their exhaust with them. Which causes the density problem. The issues with combustion is the throttle on energy. While it does throttle ok, you still cannot challenge the EVs excellent command of energy. I think we will get EV's from fuel cells. Which can refuel/charge quicker, have the protential to be lighter.

    electric car can overcome that energy density problem if they can dec charging to only 15 sec to 1 minute or lets say time taken to fill up a car at gas station. this is not possible right now but may be in future.(just saying i don't know future). 12 hours of charging(without supercharger) is real pain in ass. and i am talking about tesla.

    So clearly we just need to line the highways with Tesla coils that can power andcharge our vehicles as we drive and then we can go far with tiny batteries. Joking, but maybe...

    the thing is, the electricity charging your batteries is likely coming from a non-renewable energy source.

    I am an Iranian engineer My name is Farhad Imani I designed a car engine without the need for charging and without the need for fuel, and it's not like Tesla and others who have to charge it to travel 500 kilometers, for example, because My engine does not need to be charged at all And it practically emits gravity and leads to the movement of the car, and then during the movement it enters the second phase of production, which leads to the production of very high power and torque and speed (above 500 km). And it takes thousands of miles without charging The distance around the world that travels about 40,000 kilometers without the need for any fuel and recharge over and over again I will make it and introduce it to the world except Iran The steps of its construction in Iran It costs a maximum of 10000 $ , although later it is more important and introduced to the world

    The batteries can be recharged over & over again thousands of time. When gasoline burned its a one way chemical reaction that makes air pollution, water vapor & CO2 emissions. When you compare an EV batter to gasoline, the battery only the container for the electrons, like the gas tank. Gasoline supply chain emissions often exceed those created by burning the gasoline in an ICE Your volume & energy density comparison misses these dimensions of the larger energy picture. Please make another more comprehensive video that includes these dimensions, recharging vs refueling time & efficiency. Also consider covering the recycling EV batteries vs gasoline supply chain from mining to end use in engines that make air pollution where people are living & working & exercising & walking & breathing etc Air pollution to ICE engines a serious public health cost & issue also!

    I'm not an engineer but I enjoy their videos. Have you considered a diesel locomotive? They're powered by a diesel generator that powers electric motors that power the wheels. I guess for better TORQUE but what about efficiency?

    Carbon titanium coating of batteries really could happen, if not already in the lab. If that does work and you can charge a model Y in less than a minute, I think electric trucks would make sense if drivers stop every 3 hours for a 15 minutes break. You wouldn't use as large battery packs that you're talking about and you wouldn't really have to worry about the charge if that becomes your new way of driving. Drivers can adapt. Manual vs semi auto vs auto vs CVT's, turbos vs NA vs hybrid vs ev, 2wd vs 4wd vs AWD vs always on AWD vs electric hybrid AWD, differential vs no differential... They all drive differently and we can adapt. Even gear ratios and the number of gears, gasoline vs diesel vs propane vs natural gas vs hybrid vs electric vs hydrogen. The point I'm making is that change is inevitable and drivers ALWAYS adapt
