MG electric car Hello, ladies and gentlemen. A real show floor like the Geneva Motor Show is perhaps the best way to present a brand new car andbusiness objectives to the press and the public. Current times however challenge everybody to be creative. Luckily, we like to do things just a little bit different at MG.  This is why we have invited you again to an exciting and specialvirtual announcement today here in the House of MG. MG Motor Europe this year: In just a few minutes, we will give an update on theambitious new steps MG Motor Europe is taking this year. Believe me, MG is here to stay! But first for those who don’t know me yet. I’m Mike Belinfante, and I’m theSenior Manager PR for MG Motor Europe. I will host this exciting announcement event for you,together with our CEO, Mr. Matt Lei. We have asked for your attention, because we have a lot ofgreat news to share with you. MG will grow all over Europe and we want to update youon our expanding business. Last December, when we vi

Electric vehicles Explanation No. 9 in this lesson,heat the passenger compartment that is simply not true this is just all-electric heat so this   is what they call the positive temperature coefficient or PTC heater it has a two-wire    electrical connection right here it has a logic connection right there . Tesla Model S: for the control of it  ​and it has a big circuit board in here with a whole bunch of igbt transistors  that control current that is going to heat up uh ceramic little elements uh inside of this   many passenger compartment or coolant heaters use these ceramic heaters and this looks pretty big   but I wish I could get down the one I have for the model 3 because it's about 50 percent bigger for   the Model 3 so I assume for those of you that drive a model 3 that passenger compartment heat is   a little better is a little better performing than in a Tesla Model S . :here is a similarity to the parts of a Chevrolet Bolt EV but this grommet right here   you can see

The electric battery Explanation No. 8 in this lesson,same compressor that's used in the Model 3 as well and   it can be used in R134a systems or the R1234yf refrigerant systems it has a two-wire electrical   connection DC input it has its own built-in inverter where it inverts it into ac   and drives a little three-phase high voltage motor in here to run the air conditioning   compressor at variable speeds it has a low voltage logic connection here for can serial   data communication to the controller and this connection this dc connection to run an ac motor   is picked up off this bottom blue connection right here on the high power distribution module . Power supply to DC converter: so we'll plug that in so there's our air conditioning compressor our next   uh component that connects to the high voltage distribution block here is the dc to dc converter   this is the DC to DC converter for this vehicle we have two wire high voltage 400 volt or so power   being fed to the

  Nissan Leaf Explanation No. 7 in this lesson,circuit so if somebody takes the cover off like I did and the cables are   still connected it should open the contactors in the battery and turn off the high voltage to these   or applied to these orange cables all right now there's there are some other circuits in here   as you can see there's a circuit board right there as you can see in these photos there's   some transistors as it turns out this fuse over here on the right this 30 amp fuse   runs its power through some transistors here transistor circuit there I think there's four   uh transistors in parallel that control the current going to the battery coolant heater. The negative cable should be located on the back side:  and so it's not just a straight through always delivered it appears to be a variable amount of   of current or just an on-off circuit for the battery heater I don't know which one it is   if any of you know then put it in the comments so any

  electric car Explanation No. 6 in this lesson,right part number but it's   it's very similar uh i uh this information is at pyroswitch.com you can go look at the different   pyro switches that are made by auto leave but anyway I thought it was very interesting i   totally disassembled this yesterday and then put it back together as you can see in these   photos . New console top performance: it has a little circuit board it has a shunt circuit a parallel current circuit   uh where it appears to be watching the amount of current going through the pyro switch so this is a   pyroswitch made by auto leave there's a circuit monitoring the current going through it and   once the current going through it reaches some predetermined level I don't know what that is   uh on the press release for the p90d it said 1500 amps but the P100D is even more powerful so it   it probably has a higher rating but as soon as it gets to whatever rating tesla has decided   it's going to cap

tesla model s Fifth explanation of this lesson,sideways like this behind that, right here these two cables going out of the passenger compartment into the rapid splitter assembly okay the next two cables that we are going to connect are the ones that go to the inverter for the rear electric motor the rear drive unit the inverter in that and if you look at this photo photograph and video from underneath the car, you can see that the inverter is on the passenger side on the passenger side of the drive unit now I have right here. Connecting cables to the rear unit: the empty shell of the inverter assembly on the vehicle that we have right here our performance rear drive unit and the two cables that we're going to plug in go right down these holes and bolt to the inverter right there and that's what you're seeing here in this photograph is where those two bolts will connect so let's plug those in looks like we have battery positive on the left battery negative on the righ

Tesla Model 3 The fourth explanation of this lesson,so we now have our two cables from the charge receptacle plugged in all right now let's look at the output here of this charger module okay so these two holes on this side of our onboard charger module is the output for our DC power and they remember we just plugged in an external charger to charge the battery they need to somehow connect to the battery Method for connecting cables to the battery: so let me show you the next uh two cables that plug in here and how they connect to the battery and then we'll make the connection okay the two cables that go from the onboard charger module to the battery to charge it have to go through here are the two cables they have to go through this part right here called the rapid splitter split splitter the rapid splitter brings the two cables in from the onboard charger and it connects them directly to these two big terminals right here that plug into the top of the battery now if you look

  tesla car The third explanation of this lesson, cutting off the power to all these high voltage cables that we are talking about here, so when you shut down your car, the high voltage connectors should also shut down in an accident, they shut down if you open the interlock it should also shut down well.  We have a plastic cover here to make the connection from our charging case cables to this charger unit, and then this is the output where we have DC cables coming out DC power so I have removed all the screws from this cover so let's lift this cover and see what's inside here for the two cables to come in. From our shipping container it's down, and there's a nut in there and a nut there where it's screwing down. Correct voltage meter to enter current: Since this can have an AC voltage on it or a DC voltage, this unit must be ready to convert the AC voltage to DC or to skip the switch and send the DC voltage directly from the DC to the battery so let's talk abo

Power Electronics   Continue the explanation of the first lesson to fully understand the idea. You can see the big poster here that says 48 amps means that 48 amps is the maximum power this can take from the second level AC charger that you connect to a Tesla destination charger and 48 amps is double the 240 volts at the destination Tesla Cha will give us a rger of 11520 watts or 11.52 kilowatts of charge that this unit can provide for the high-voltage battery. Explanation of installing connections:  So let's take a look at the connections around this thing. We have the coolant inlet port here on the passenger side. If you look at this article from under the passenger seat of your Tesla , you can see that we have a logical low voltage connection here. We have the coolant hose actually coming from. The inverter set on the engine and the drive unit underneath the car and then that passes through the big heatsink here and exits this side and then goes up to the front of the car on th

   Power Electronics Today we're going to look at all the high voltage components, all the power electronics, the high voltage cables, and everything high voltage on the Tesla Model S , the second generation of the Tesla Model S, we have one here on the hoist, the 2018 Tesla Model S P100D the performance version of this model. s. And so I thought while I was carrying this car on the crane, I want to track all of that high-voltage orange cables and see everything they're calling and it turns out there's roughly 74 feet or 22.56 meters of that high-voltage orange cable on this car. Model S cables and common components:  There are 11 high voltage components connected to it and I want to show you where they are in the car and how they are finally connected to the high voltage battery Now these orange cables come in different diameters or sizes on the car, this piece of cable that I cut here if you look at the final view here is the inner copper core The one that I measured has
