The new second generation of 100% electric vehicles

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

Understanding the Tesla Model S | Power Electronics ( 9 )

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

Understanding the Tesla Model S | Power Electronics ( 8 )

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

Understanding the Tesla Model S | Power Electronics ( 7 )

  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

Understanding the Tesla Model S | Power Electronics ( 6 )

  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

Understanding the Tesla Model S | Power Electronics ( 5 )

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

Understanding the Tesla Model S | Power Electronics ( 4 )

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
