It's now cheaper to run a Diesel than an EV ! [Must know numbers for EV ownership]

hey guys and welcome to petroped now last month I made a video with my Hender group long-termer the Mustang Mac e talking about the challenges of owning an EV if you didn't have your own off street parking and your own charging and that video has had an unbelievable response it's very nearly done one million views and there were thousands and thousands of comments and there were many questions and many points raised in those comments and I thought I would do a bit of a follow-up video firstly a couple of my predictions have come true already I stated that I didn't think that free Road fund license for EVS would last very much longer and within a couple of weeks of that video going live the UK government announced in their Autumn statement that from 2025 here in the UK electric cars will pay Road fund license just like any other vehicle but lots of you said that you found that video very useful especially those of you thinking about buying an electric car but I had lots of questions about all of the numbers related to owning an electric car this video we're going to debunk some of those numbers and also look into an AAA report that came out just a couple of weeks ago that suggested here in the UK it's actually cheaper to run a diesel car at the moment than it is to run an EV if you don't have your own charging [Music] thank you now before we start I always find it amusing what people pick up on on videos and a lot of you said I've parked my electric car right in front of a stack of logs how green am I a couple of things firstly we're on oil-fired central heating here and we are actually looking to move next year towards a solar panel array on the roof of This Barn a Tesla power wall and removing our oil-fired central heating with an air source heat pump but until we do that arguably burning logs in a wood burner is far more sustainable and environmentally friendly than burning oil so there we go anyway first of the numbers I want to talk about is battery size okay then so when you're buying your EV one of the first numbers you're going to come across is how big the battery pack is or the size of the batteries and think of this as an analogy anyway to the size of your fuel tank in your petrol or diesel car the bigger the number the bigger the battery pack the further the car is going to go the unit of measurement for the battery pack size is kilowatt hours and that can range from for a small City EV maybe 30 or 40 or 50 kilowatt hours to the really big ones 90 to 100 kilowatt hours now this particular car this is a long range Mustang Mackie has a 98.7 kilowatt hour battery but only 91 kilowatt hours of that are usable and you think why is that well I will actually come to that a little bit later you might not tap into all of the battery pack size the other thing that battery pack you might and I had an EV press car the other week that referred to that as the traction battery or the high voltage battery that battery pack is the battery that's going to power the motor that makes you go forward but all EVS will also have a low voltage battery effectively a 12v battery that will run all of the ancillaries things like your air conditioning your lighting and so on so you'll have two batteries the other number that you might hear refer to when you're talking about battery pack is the voltage it's running at so this particular car runs on a 400 volt system and some newer EVS especially the ones that are aimed around being able to do very fast charging May well have an 800 volt system again the bigger the number that is now the faster the charging can take place when you are plugged into a DC charger more on that later now before you say anything I know the car is filthy it is freezing conditions here in the UK at the moment lots of salt on the road and it's way too cold to be washing the car for a start I think my hose is probably Frozen anyway but let's talk about charging there are two basic types of charging for an electric car AC charging and DC charging AC standing for alternating current DC standing for direct current let's talk about AC first this is the type of charging that you're going to find at home and in a lot of public places like supermarkets and car Parks so there are three speeds that you are likely to come across with AC charging the first and slowest of them is what I sometimes refer to as granny charging but it's the type of charge cable that will come with every electric car that on one hand has a domestic power socket so in the UK we call that a three pin plug for my American audience you just got two pins on your domestic power sockets and on the other end is the connector that plugs into your car now the unit of measurement for Speed of charging is now kilowatts so battery pack was kilowatt hours speed of charging is kilowatts I am as guilty as the next person and a few people pick me up on it I often mix those up but if you are being pedantic the speed is kilowatts the size of battery pack is kilowatt hours now if you are on a three pin plug at the at home on what we call single phase power you're going to be looking at a charge speed of around about two kilowatts maybe up to three kilowatts to get the speed by the way you multiply the voltage by the current now in the US so in the UK we have 240 volt electric supply domestically in the US you have 120. so these numbers are going to be slightly different in the US so that is a slow speed charger and to get the speed of charging you basically divide the size of the battery pack by the speed of the charge with me so far hopefully so that's a really slow way to charge your car um it would be fine if you had a plug-in hybrid I know plenty of people who run a plug-in hybrid off of a three pin two kilowatt charger at home it's not a massive battery pack in most plug-in hybrids and that is fine but if you've got a full-blown EV you will find it very painful indeed to plug in your car to a domestic two kilowatt charger so what you now need is a seven kilowatt wall box now I've got one of those behind me I'll just get it so first off this is now an installation you can't just plug this into your domestic Supply you'll need an electrician to come out and run cables to your garage or outside space again in my video I said that um there were subsidies for this when I got this and if you bought a car at the time you would get a subsidy for your charger I believe now in the UK that doesn't exist and in many countries the feedback you gave me is that doesn't exist so with the Charger and the cost of installation you could be looking at anything up to around a thousand pounds to get a charger like that installed but now this is now running at a speed of around seven kilowatts so if you did your maths and I'll I'll round the numbers up to make it easy let's say for the example this car had a 70 kilowatt hour battery pack and I charge it with a seven kilowatt charger that is 10 hours to charge the car 70 kilowatts divided by sorry 70 kilowatt hours divided by 7 kilowatts hopefully that makes sense so even if you had a big battery pack in your car like this very nearly 100 kilowatt hours on a seven kilowatt charger you're looking at maybe sort of seven to ten hours for a full charge now when you look at public charging infrastructure a lot of the free charging you might find at somewhere like a supermarket or the lamp post charges that many of you commented on a lot of those are seven kilowatts so yes they will charge almost think of it like a trickle charger but it's not something where you would go and plug in for an hour while you have a coffee and wait for your car to charge this is an overnight charge really seven to ten hours now AC charging does have a faster variant at 22 kilowatts however in the UK and it's the case in many countries most domestic power supplies are what we call single phase and you can get three phase power supplies however that's normally in some kind of commercial premises and with three phase I don't know if you can spot this but there are three pins in this connector and if you're using a single phase so domestic power supply you're only really using one of those pins as soon as you go three phase you use all three pins it triples the rate so you're now charging at around 22 kilowatts it's three times as fast something you probably wouldn't have at home the cost of installing three-phase at home is either likely to be too much or just the infrastructure into your home is maybe not able to support it but in some commercial premises you may well find in some hotels in other public infrastructure that you're charging at 22 kilowatts and you're still using one of these type 2 charges so that is AC charging so we've done AC charging let's talk about DC charging now if I am being pedantic as well the actual charger is in the car so these really are charge points but that's splitting hairs so so far AC charging we said your domestic one was seven kilowatts you could do that up to 22 kilowatts there is some terminology so slow charging is defined as up to seven kilowatts and fast charging is up to 22 kilowatts so they are both in the Realms of AC so what we're now talking about is rapid charging and Rapid charging is anything from 22 kilowatts up to 100 kilowatts now my nearest DC charger is a 50 kilowatt charger here at the Goodwood Aerodrome so I've come to my beloved Goodwood to describe a little bit more now the type of connector is going to change now there are a couple of different types of connectors there's something called chademo which I've never actually yet had on a car that I've been reviewing but by Far and Away the most common is this it's something called a CCS charger now if you look behind the charge port on the car first off the the top part of the charger there is the same shape as the AC connector that I would put in and then you've got this bottom part as well so this is now DC charging at 50 kilowatts so to put that into context let's say the Mackie 100 kilowatt hour battery 50 kilowatt charger I should be able to get a full 100 charge at about two hours so it is much much faster we've gone from sort of seven to eight hours to two hours and Rapid charges go up to 100 kilowatts so if this was a 100 kilowatt charger I could charge that car in an hour and then you are now also able to although they are far less common than the 50 kilowatt charger you're now able to get what we call Ultra rapid charging which is basically anything over 100 kilowatts and I've been to a couple of 350 kilowatt charge sites and if your car will take it because once you get to that kind of speed it's about the voltage remember we talked about 400 or 800 volt systems but if you were charging at 350 kilowatts for a car like that we're now talking about 20 25 minutes to charge the car it's a simple amount of math this is like a fire hose if I want to fill up a swimming pool the faster the charger the bigger the fire hose the more water is going to come through it the faster the swimming pool fills up it's that simple your biggest challenge with 50 kilowatt and above charges is just finding them they are far less frequent when you look at how many charges and they're often quoted the number of public charges in the UK for example or in any country you live in will be a really big number but a very large proportion of that will be AC charges the faster charges from 50 kilowatts and above this is the kind you really want if you want that Vault and bolt if you want to stop have a coffee fill your car up you want the bigger kilowatt number you can get so on my zap map app and there are others available that will tell you where your local charges are you can filters that just filter off anything slower than 50 kilowatts that's what I do anyway I think all the different types of charges is one of the most complicated things about owning an EV but if that's all the different speed of charging what about cost of charging now I wanted to just talk about a lot of you commented on the fact that you could charge at work for free and I totally understand that I know plenty of employers that currently offer free charging I think my point was in my previous video how long will that last especially with the current cost of electricity the energy costs for businesses are going up so much that maybe some businesses will look at the cost of allowing their employees to charge during the day for free and make adjustments and and start to charge so that may well be the case but in general what about the cost of charging well here in the UK the AAA the Automobile Association did a brilliant piece of research recently so let's just talk about some of their findings according to a new AAA report EVS can lose out to diesel cars when looking at the Pence per mile cost it found that running a diesel is cheaper for Ev drivers who do not have any form of personal dedicated off-stream charging the report confirms that domestic charging is the cheapest option for Ev owners domestic charging is also half the price of ultra rapid options fast charges also represent the most common charge point in the public network outnumbering rapid and Ultra rapid devices by more than three to one however slow charging providers often offer subscription Services which unlock rates lower than the average fast charging price for those without any personal dedicated off-street charging running a diesel is cheaper at 13.25 Pence per mile in contrast with all but Ultra rapid charges petrol is more expensive on a pence per mile basis of 14.62 Pence per mile but for all EV drivers using a combination of domestic charging and Ultra rapid top-ups is cheaper than running a petrol or diesel car now in piston cars we're all used to efficiency measures we're all probably more than happy with what miles per gallon or liters per kilometer mean but when you get in an electric car those two measures don't mean anything the measure you need to understand is miles per kilowatt hour or I guess you could look at kilometers per kilowatt hour if you are in the metric system it's kind of confusing a little bit because we're in the crossover of metric and Imperial we do both here in the UK but it's a really really simple measure it is literally a measure of how efficiently the car is going to get along the road now let's try and simplify the maths imagine this car has a 100 kilowatt hour battery pack and the car says I'm doing three miles per kilowatt hour do the maths just multiply the two together and that means at that level of efficiency you should get 300 miles on a full battery pack so cars that are least efficient if I get in an EV doing a road test and I'm looking at efficiencies of two between two and three miles per kilowatt hour I'm not particularly impressed anything over kind of three and a half to four and I'm hugely impressed now that number also is massively impacted by how you drive and how heavy your right foot is but some electric car manufacturers just have more efficient powertrains more efficient aerodynamics and that miles per kilowatt hour figure is just a really good indicator of how efficient that car is in turning the charge in the battery pack into kinetic energy and making it go forwards okay let's talk range the most commonly talked about thing whenever it comes to electric cars oh they don't have enough range so range is a combination of how big your battery pack is and how efficient your vehicle is so you say okay I'll buy the most efficient vehicle I can with the biggest battery pack well yes but it's not quite that simple the bigger the battery pack that will mean typically the car is bigger and it will be heavier and it will cost more so that sometimes isn't for a smaller City car that's just not an option so for sure those two things have a big impact but it's just like the range in a petrol or diesel car the way you drive it has a massive impact hard acceleration will deplete the battery quicker um the big killer for electric cars and actually this isn't a problem for me because I'm stuck behind this truck is speed so drag aerodynamic Dragon mechanical drag increases with speed and therefore if you were for example on a Motorway or a dual carriageway and you set your cruise control at 50 miles an hour compared with someone who set their cruise control at 70 miles an hour you're going to get more range because drag squares with speed the faster you go the more drag you get the less range you're gonna get so that's why you'll often get if you were just doing lots of town driving you're going to get more range out of your car than if you were doing long distances at higher speed the other thing that hampers range and this is definitely the case at the moment here in the UK because it's winter time and currently the outside temperature is only one degree Celsius is that has a huge impact on battery efficiency and what you'll find and I'm sure many of you who own electric cars are finding this in the winter time your range depletes or decreases significantly so this extended range Mac e um it doesn't do anywhere near the quoted figures of nearly 300 miles but in the summertime you know 250 maybe 260 miles was doable at the moment in the cold on 100 charge in the morning it's indicating about 160 to 170 miles and I know someone who's got a mini electric at the moment they're currently struggling to get 90 miles out of it now there are some things you can do to alleviate that problem um most EVS will come with an app and while the car is still plugged into your charger in the morning you can go into your app and preheat your car so get it all nice and toasty inside but also do what we call pre-condition the batteries that warms the batteries up and that helps with efficiency but the heater will kill your range as well I was in an EV just last week and just by turning the heater off my range my predicted range of the computer in the car went from 140 miles to 190 miles by turning the heating off now the last thing to mention is what a lot of Manufacturers will do is their predicted range is done with an algorithm on a computer and I mentioned this in my um in my last video lots of you pulled me up on it if you if you um clear the driving history your predicted range in your car goes right to the maximum that manufacturer will do and then over a period of time the algorithm works out what your actual range is likely to be um so you could do that but what a lot of those algorithms do is actually protect the battery by not utilizing all of it so even when your predicted range is showing zero a lot of Manufacturers will still have maybe 10 of the battery uh actually in or power in the battery and they do that to help protect the battery and provide things like longer warranties on batteries and then the final thing just to mention very briefly as we're going so slowly and I've got a nice long journey is and this this literally could be a whole video in its own right is that the kind of best practice really is to keep your battery between 20 and 80 charge now the first 20 and last 20 of your batteries charge take the longest it's to do with how the electricity and the power goes into the battery it kind of trickles in to start with up to 20 and then from 20 to 80 you get your most efficient or most uh rapid charging and then it tails off at the end the last 20 percent so it's not such a problem if you're just charging overnight but if you're rapid charging in public the best practice if you keep between 80 uh sorry 20 to 80 percent that's your fastest way to charge so you know you can you can nip into a rapid charger stick it on there um you know charge from let's say 20 to 60 or 80 in half hour 40 minutes and then go that's quicker than if you hang on until you've done all your 100 charging and I know the problem with that many people will point out is that means that if your range let's say you're doing a range of I don't know um uh 100 miles I'll keep my mats easy and you only stick between 20 to 80 you're only actually utilizing 60 of the battery that means your range isn't 100 miles it's really 60 miles um but that's that's more to do with this the the most efficient using your charge infrastructure as efficiently as possible but range oh my goodness what a topic that is we could literally talk about that for hours next set of numbers is all to do with power not the power of the charging the power of the car I guess the first thing to say is whether you are metric or imperial so whether you talk about horsepower or metric horsepower I'm going to go into the world of metric and talk about metric horsepower or Ps for distressor because a lot of EVS will be quoted in PS however if I was being entirely accurate because this is an electric motor I should be quoting power in terms of kilowatts not horsepower so you therefore need to know the relationship between a kilowatt of power and a metric horsepower and one kilowatt of power is 1.35 metric horsepower so this car for example has 351 metric horsepower and that equates to 258 kilowatts now I think it's fair to say that although the correct way to quote power of an electric car is in kilowatts most manufacturers and most reviewers and magazines and so on that you'll look at mix them all up you'll see a combination of metric horsepower brake horsepower kilowatts but that's the relationship [Music] now the last number I want to talk about is kind of the same and that is talk now again um I get berated quite a lot because in talk numbers I often quote talk in metric talk which is Newton meters but I appreciate that many of you live in Imperial land and we'll want to talk in foot pounds now either one is applicable you will find that I think a lot of electric cars will be quoted in newton meters because it's uh typically more kind of ties in with the metric uh kilowatt electric description and the thing you will find about a lot of electric cars is they have really high torque output so this Mackie for example has 580 newton meters of torque which is a lot however for me the important thing about torque in electric cars is not so much about the number it's about the torque delivery so I could have a piston car that has a lot of torque so something like an Aston Martin DBS super legera for example that produces 900 newton meters of torque but it's on a torque curve and that torque curve goes up through the Rev range and you'll find Peak torque depending on the car at somewhere probably between I don't know four and a half to six thousand RPM in an electric car that torque figure so this this car the 580 newton meters that this car has in terms of torque is available all the time from zero RPM it's not a torque curve it's a flat line and it's this instant talk that you will hear people talking about in electric cars the second I put my foot on the throttle I've got that torque so talking electric cars yes the number's going to be higher yes it's likely to be quoted in newton meters but it's available from zero RPM and that totally transforms the driving characteristics of the car now guys I hope you enjoyed that one I'm sure there are some numbers I've forgotten if there are please put in the comments below I'm sure some of you might take debate at some of the descriptions I've used I was trying to simplify as much as possible but keep it as accurate as possible but honestly I think when you're coming into electric from scratch and you alert doing all your learnings it can sound very confusing but when you break the numbers down and when you understand them it really isn't that bad um put in the comments below I would love to know what you think of that one um but if you've enjoyed it then please give me a thumbs up comments below are always welcome and if you haven't done so already please subscribe to petrified for plenty more content to come and I'll see you on the next film guys you take care drive safe thank you foreign [Music]
