 It is Okay, well first I should start with my name right a Raphael be a costa Miranda and yours is Catherine mm-hmm and We are here to discuss because we have gotten together and we are going to discuss our project on electric vehicles and Personal or or mass transit, but we're going to concentrate I guess a little bit more on the personal vehicles Which are the most that are out there I guess Just like the Gas engines there are several several types of electric vehicles. They're also known as EVs and We're going to discuss a little bit about what types of EVs there are and there are advantages and disadvantages The electric vehicles are either all electric vehicles that means that they operate only on electricity or they can be also What they call a plug-in hybrid electric vehicles which run on electricity and Gas lane The advantages and disadvantages of the electric vehicles. Well, let me go back a little The electric vehicles the a EVs all electric vehicles they only use one source of power and that's as electricity They're range the range can go to Somewhere around 80 miles to 100 miles with one charge There are some a luxury models that can go farther than that of course, but They could go up to like 250 miles In one charge, but of course, they're going to cost more charge an AEV it could take up to 30 minutes on a fast charge or Depending on your charging method There are there are three types of charging methods and I have them here and I'll read them real quick Charging level one is the method that you can just plug it into an 110 outlet Probably from your your most likely from your house or even from your work But this is the most slowest method of charging and it would take somewhere around two to five Miles a charge per hour So to just do five miles it would take an hour to charge That's miles Level two with this message you can charge an AAV through a 240 volt System either residential or 208 volt from our commercial It requires a little bit more equipment and For a faster charge, but it can deliver 10 to 20 miles of charging per hour So you get a little bit more For less time Then you have the DC fast charge This method you can charge an AEV Through a 480 volt AC Input it requires a specialized highly specialized highly powered equipment too So this is going to bring up the cost a little bit more so that you can get that extra faster charge But if you look at it it charge a 60 to 80 miles in 20 minutes I actually found a really interesting podcast by an economist in Germany and She has been specifically studying the idea of how much electric batteries cost against traditional engines and One of her points was that the faster you charge the battery The longer the overall lifetime will be if you're not doing a low and slow charge. And so she was talking about Maybe not so much changing how we charge it but Putting the charges at places like grocery stores or movie theaters places where you're gonna be able to leave them Plugged in longer or your workplace But they can stay there for a long time and it that still doesn't disrupt your every day Nice. Yeah, that's interesting Other than that, that's the three levels of charging that I found for the AVEs AEVs Letters here, but and then the second type of electric vehicle is the plug-in hybrid hybrid electric vehicles These vehicles run somewhere around 40 to 60 miles on the charge and once that charge is gone It converts into a gasoline motor So the the advantages of this is that if you're going on a long trip you can Do this in this car because it'll convert into a Gasoline engine and you can continue to to drive down the road but the other advantage of this is that while that Gasoline engine is running it is also charging your batteries So you don't really need an external source source to get that battery going Yeah, and I saw that I saw that both both types also use regenerative braking Yes, that's correct. They do you use that regenerated braking? I have no idea how that works pretty cool Yeah, it blows me away when you just break and it comes it gives you that extra push there or whatever, you know, but uh That's basically the two types of Electric vehicles that I found There's some other, you know, like like everything else. There's some other Kinds, but they go into those two, but those are the two main Sources that I found The advantages of the and the disadvantages of the EVs I'll start with the advantages They are more environmentally friendly EVs do not have an exhaust system, so they don't do not create a they create zero emissions a Gas powered cars are we know that are the largest contributors to greenhouse built up in the air's atmosphere Electric cars can contribute to clean and clean air and a healthier planet Uh The next one is electric is cheaper than gasoline it usually Compares to like a third of what gasoline cost. I don't know. Did you did you find anything else? That's maybe cheaper than that? Um, I So I was I Found something from out of the Idaho National Laboratory and according to their study. They found that operating Cost of a mile traveled an electric vehicle can be three to five times less than a mile in a gasoline Your sources and my sources are more or less than the same Okay, they're in the same picture minds are like a third or something like that So, but I guess they were doing it by how much of electricity is used Compared to a gallon of gasoline, right? And that's how they got there. Uh, the comparison Another advantage is that that uses less maintenance. I guess it's because basically in a in a Gasling engine, there's a lot of moving parts and there's a lot of friction and everything and they get destroyed a lot faster than an electric car Which is hardly no moving parts Plus, you don't have to use oil that you don't have to change oil and stuff like that, you know that or any lubricants in these in these engines So your maintenance is less I'm wondering if the tires are it's a better run on the tires too and everything since they I don't know that maybe they might not be Too hard on the tires being that they're more gentle on the road or something. I'm not sure, you know How those brakes work too Okay, they are very quiet and They are so quiet that there has been some legislation in the US that they want to put noise making Systems in these cars so the pedestrians Yeah, because they're so so quiet you're just walking out to the street and you don't hear the car coming So they want to put like the noise making like a car engine in these things because of this problem But that's one of the advantages especially here in the city and you have these cars Well, you know, it's not not they don't make too much. They don't make noise at all Speaking of that When I was looking for I was kind of looking for case studies To see I've already been using them and I live pretty close to Washington, DC And it turns out that in 2018 DC bought 14 100 electric buses to run their circulator route and You know, like you're saying in a big city like that Sometimes, you know, sometimes them being that quiet might be an issue but To to work on reducing the noise pollution of such a dense urban area would be Incredible they're hoping to buy 18 more in the near future and they want to eventually go to all electric Buses for their entire fleet Nice. Yeah It was nice to see someone actually taking steps They are and that's one of the things I'm gonna touch on on the later notice is the It's not being put out there the advantages and disadvantages of these of these cars I don't think they're giving enough promotion for the people to know what what's out there, right? Yeah I was saying right although there are a lot of tax incentives and Other monetary incentives, but it's not it's not even at all, you know different states give more Than others. Yes, and that was and that is actually my next advantage is that you can get tax credits Having a non a zero-emission vehicle And in the article I was reading it it said that you could get it up to $7,500 depending on, you know, what type of vehicle and what it has and you know, but That's one of another advantage is that it has and the last advantage that I have here is And this could be like in the cities you can shorten your commute because by driving an EV You can use the What is that called the Carpool lane, even if you're driving alone Because I guess they want you to get to your destination faster So you don't spend your battery in like a traffic jam or something like that, which would be very bad People would not be so so keen on that Exactly and then I have the disadvantages. I have five disadvantages here The most ebbs have a short range. We talked about that before 80 to 100 miles or 60 to 100 miles and But only a few can go like 200 and 300 miles the more luxury Talking having to buy a Tesla or something about yes And and the prices on the Tesla's I was looking at their website and they are outrageous. I guess they have not made a Single dime on those cars yet because they're so expensive, right? They're making them so that just to get rid of them So something interesting I found on that note Oh The battery production costs have actually decreased 80% Wow, it's just that they were so expensive to begin with It's it'll it should continue to fall as they as they improve the technology. I Hope so. Yeah. Yeah, I hope so Let me see We charge it can take longer Then just filling up with gas Okay The initial cost of an EV can be big and some models can go to 30 to 40 thousand dollars And the luxury models can go up to $80,000. Yeah, I mean I'm the all the other perks that you want to put in it Charging stations are not always available. That's another problem. They are starting to move out from the into the in The cities and stuff like that, but when you get to like the rural areas There's not much out there and you and if you go out you can you can get stuck easily if you don't know where you're going Yeah And then there there's not a big priority pack to pick from not like you go to a Regular auto dealer and you can pick and choose Tremendous amount of models. They only have specific models for that and that I started looking into like There was more trucks around if there was more vans around and they're starting to come out with that too So it little by little it is spreading more and it's getting the viaries going to be better Yeah, I Believe that the EVs is the future It has to be if we want to live in a world that has a clean atmosphere The diesel and gas trucks They create so much Greenhouse gases that you know, it can be very damaged to the atmosphere We now tend to this trend, you know, we don't know what the future will be I believe that the technology is there to make it better Electric vehicles of battery Are gonna be improved to have a longer life and better Charging methods so I think the technology is is there or is almost there to have this done But I also believe that EBS have not been promoted enough and that the consumer is not aware of their advantages and disadvantages Yeah, I think there's also is in the case with most renewable energies Disinformation being put out one thing that I had heard Particularly concerning. I think they use Tesla as the example People were saying you would have to drive an EV for about eight years to offset the environmental impacts of the production of the battery and the disposal of it and This is again going back to that podcast I was talking about and she's saying that this it was taken from a single Swedish study Where they went in and cherry-picked the absolute worst case scenario and then are now dispersing this Completely out of context Yeah, yeah That's bad. That's too bad But like I said, I think this is the future matter of fact. I I wish I could buy one, you know yeah, because It would be neat to just go around and Not waste any Gasoline and just plug it in much cheaper. I I kind of see it It'd be even better if they could Get it into public transportation like what if you could run? What if you could run a train on one of these? Oh my god? Yes We have a commuter train that goes up and down from DC it goes. I mean, it's what? 54 miles down to the most subtly station All of that yeah, all that track and all those people Yeah, running on electric. It'd be it'd be incredible or tractor trailers There you go all that cargo shipping Yeah, yeah, well like like we talked about earlier about the the trends is I have an article here from clean Technia that says that By the year 2040, California is going to be all electric buses for their Shuttles and Public transportation So that's going to bring according to this article according to the electric vehicle research The new regulation is part of a statewide effort to reduce emissions From the transportation sector which accounts for 40% of the carbon dioxin emissions and up to 90% of the pollutants that cause smart Wow So when fully implemented the regulation expects to reduce greenhouse gas emissions by 9 million metric tons from 220 to 200 I mean 2020 2050 and that's like taking off like four million cars out of That's incredible. That's amazing and if they can do that and those calculations are correct and it's it's a wonderful thing And it's it's also important to remember, you know, it's only as clean as The electricity that it's being charged with is So actually, I think we both use the energy department's website for some of our information Yes, and they have a tool where you can actually go in and click on your state and it'll break down the power percentages that's that are fueling your states you can see, you know, like How much of the electricity that I'm using is coal power as opposed to renewable energy? Yeah So, I mean, you know, whatever argument they might have against it as energy in general becomes cleaner. It's going to make Electric vehicles more accessible too Nice, I agree Okay, okay. I have I Think I think we covered everything that we had talked about Covering very nice very nice. Well, it was really nice You have a fantastic night, okay, but I have a question. How do I how do I get it from you so I can post it? I don't know here. Let me stop
