    00:00:05 the Porsche tyon is one of the most impressive Feats of Automotive Engineering on the road today and I am here in stut guard Germany to talk to Porsche about this vehicle to find out how they took it from very good to very very good with the latest [Music] update the vehicle has a lot charger battery pack it has more range it

    00:00:32 charges quicker from an already impressive 270 KW and it does all that while being lighter so how is the tyon able to pull all this off well I'm here with clous reberger you're a director of Powertrain for this vehicle you're in charge of the powertrain you're in charge of the battery the tyon was a great vehicle tell me the the process to make

    00:00:58 it what it is today yeah when we uh launched the first taon we were very proud of it and uh of course after three years we had to bring some new ideas into the vehicle so with uh increased power we reduced charging time and we also increased of course the range of the vehicle which are the most important points in the electric vehicle and power of course is Porsche alike and not only

    00:01:28 Power for the drives but also bring it to the [Music] road so one of the more impressive uh changes to the new tyon is the increase in power this is a 24% increase from a vehicle that was already really powerful so talk us through what uh what you and what Porsche did in order to to to to generate that much energy yeah I think

    00:01:55 uh the the power increase in total is even more than 24% but on the rear axle it is 24% up to 450 KW wow the uh electric motor was completely new designed so we did a lot we did the new uh magnetic design MH uh so we changed the v-shaped magnets we changed the metal sheets and we changed also in the magnets they were separated from each other to incre to reduce the losses mhm

    00:02:28 uh these were the main changes in the El motor then of course we did also some software changes in the Ina so uh the pwm the pulse with modulation was changed so uh the philosophy was to even get more out voltage so that we changed the modulation strategy mhm and this was to increase power and to reduce losses we also adopted the frequen quency of the uh pulse width

    00:03:04 modulation uh according to the speed of the motors so if it is a low speed we also do a low frequency uh switching and uh This was done with a lot of improvements so uh that we also did uh so socalled frequency wobbling so that it was not always the same frequency but changed slightly in also three use the noise which is coming out M and with let's say a sort of measures we could

    00:03:37 increase the total power wow it also reduce the losses and the weight which is a very important issue for Porsche so lighter but also quicker yes so extra quicker the the frequency like previously was it like a like the same frequency regardless of how how quickly the motor was turning yeah it was it was the same frequency and now we changed it so that at low frequ at low speed we

    00:04:03 reduced it to 4 khz and according to the speed of uh the vehicle then we increased and yes so that we get out maximum uh Power with reduced losses one of the more interesting aspects of the porset hion is the fact that it has a two-speed gearbox most EVS have a single speed and what's great as that when you're driving you can actually hear and feel the second gear

    00:04:37 kicking in can you talk a little bit about the philosophy of of adding that to uh this vehicle whereas everyone else essentially has a single speed gearbox yes uh when we first launched the first generation of the tyon we have seen that the two-speed uh electric motor allows us uh to have on the the first point maximum acceleration at low speed and very high efficiency at high speed

    00:05:08 though it's let's say of course a two-speed uh gearbox is more complicated M so you have to manage the switching and uh the the gear changes and this stuff but especially for efficiency at high speed and to get uh the the range of the electric vehicle we had chosen this efficiency for high speed and maximum acceleration at low speed and this

    00:05:37 that's all behind this and of course we also improved it in the second generation now uh we reduced friction but only slight changes but as you know Porsche is always it's our stuff always to find where we can go to the edge yeah to the next level Next Level yeah initially was there an idea to use a single speed or was it always two speed uh yeah of course we did some

    00:06:02 investigations also in the single speed when we started but this is a long time ago yeah yeah uh but uh it uh let's say it was uh a decision which was really really made very early mhm and we have seen that with this decision we can make a typical Porsche electric vehicle with is a Porsche this is the main idea behind all this [Music]

    00:06:33 let's dive a little deeper into the motor let's talk about the hairpins typically people are using rounded hair pins you're using rectangular hair pins what is the technical reason for that uh the electrical engineers uh they designed uh the the the target is always to get as much copper as possible into the the nuts of the electrical machine and that's was the decision that was the

    00:06:58 decision and the the reason be the rectangular hair prints so that with this uh shape of the copper wire we could increase the copper filling MH in the slots of uh the electrical machine and this is also a point of uh maximum power and reduced losses so the slots has to has to be filled MH as full as possible and with this rectangular shape this was uh the

    00:07:31 reason behind so most electric machine cram as much copper as you can as much as possible into the slots of the electrical [Music] machine one of the more exciting aspects of the first generation tyon was Repeat Performance the ability in an EV to keep doing the same thing again and again and again with nearly the same amount of

    00:07:58 performance how have you incre inre that in this uh generation vehicle uh we increased this in the way that uh we we reduced the losses so that if we don't produce any heat in the electrical machine or in the battery we do not have to get it out and uh so that all uh components kept cool or in the thermal management and together with the increased efficiency and the improved

    00:08:29 thermal management M we can could also increase the Repeat Performance and Repeat Performance is Porsche you have to do it again and again and again and not only once or twice again and again that's our Target and with these measures let's say yeah improving efficiency and also improving the thermal management we achieved this target what's interesting is in the

    00:08:55 vehicle as a driver you can see like the battery temperature and all these other things these are things that most evv makers aren't sharing with the drivers is this most is this just part of Porsche's yeah I think uh a lot of our customers uh let's say they are technically interested and so we had we have also a lot of instruments in our IC Vehicles where you can see old

    00:09:19 temperature you can see old temperatures you can see the speed of the engine and I think we our customers also want to know what is with the vehicle how does it work how does it feel uh how can I know what the we vehicle vehicle is now capable of doing it and that's why we inform our customers about this yeah they like it to be technical in the vehicle not only passenger but in the

    00:09:47 vehicle that's our let's say philosophy behind this yeah so one thing that people probably don't think about as much as they should um and especially when you're traveling is charging rates you know how quickly can your vehicle charge at Peak Performance and the tyon you've increased it it was already a pretty high number talk tell me a little bit

    00:10:13 about like what you've done to increase it and how you were able to do that yeah okay uh from the beginning we started with 800 volts this was of course uh the main step let's say in the next level of charging and so we started with 270 KW with the first generation and now we increased it up to up to 320 KW um in even for let's say a wider range of uh for the state of charge uh

    00:10:45 up to let's say 50 60 Kow and then slightly reducing the power of course for the the customer benefit out of this is to reduce the time for charging so to have a longer uh better traveling distance and this was behind the idea and also of course uh competitiveness M we've seen that competitors are coming up and we like competition so we want to be better and

    00:11:16 yeah with the new battery on the one hand the new battery was with increased uh with increased energy mhm and also reduced uh resistance inside so the Lost the heat which is produced out is reduced we improved the thermal Management on the one hand getting out the heat of of the battery and also uh getting out of the vehicle and of course we improved

    00:11:46 chemistry chemistry let's say we did a lot of effort investigation how can it be achieved so that we get let's say on the limit of the battery yeah and we learned a lot out of the first generation so the first generation was not on the limit so we could learn about and improve and increase the power with this and then that you also incre increase the range

    00:12:14 so with all this you've also added more range to the vehicle yeah the range uh I'd say uh one first point is of course to increase the energy of the battery by coming from uh 94 KW hours going up to 105 KW hours of course one of the main points but not only putting energy into the vehicle but also improving uh aerodynamics improving electric motors

    00:12:43 we discussed also this points about so we've reduced uh all points where we have losses in the vehicle we reduced this and of course we increased energy of the battery and out together we all these measures which which say is a bundle of measures we could increase the range of the vehicle which is also the most benefit point for our customers so get it coming with the first generation

    00:13:13 and now with this facelift I think we de really achieved a good job with this car [Music] yeah the decision to have an 800 volt architecture how did that come about yeah when we started uh let's say 2015 to think about the architecture of the new tyan we thought about increasing voltage uh in order to improve the efficiency on the one hand

    00:13:42 but the main issue was to reduce charging time because this was always in mind of the customers uh electric uh cars it takes a long time to charge so that traveling from A to B takes a long time and so we thought about increasing volage volage so that we could reduce charging time but it was not so easy to start this because our competitors had 400 volts and most of our suppliers also

    00:14:10 sticked to 400 volts um and so we had to do a lot of uh work to convince our C to to convince our suppliers that they had to go that they should go the way with us MH and I think yeah it was a good decis decision to go this way and now we see that there are a lot of competitors coming up with 800 volts and I think we get a new standard with 800 volts and this we are we are proud of

    00:14:40 [Music] this second generation tyon I know it's early to start asking about this but third generation Fortune the future of electrification for Porsche it's electrification is exciting and do you do you are are you already thinking about the Next Generation yes of course we are thinking about the Next

    00:15:02 Generation uh now we have launched this let's say the second generation which is not only a facelift but we really made a new statement and we are now thinking about the Next Generation we has let's say have the challenge accepted competitors are coming up we like competition and that's why we are thinking about of course fast charging we are thinking about electrical drives

    00:15:28 Improvement and all this stuff also air uh aerodynamics all this stuff are in our mind to be improved MH and I think we can be we can we can't hard we can hardly wait uh how to bring out a new ideas onto the road and show our customers what we all thinking about yeah cool thank you so much CLA for more videos
