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 in this photograph going through the bulkhead connection at the front of the vehicle under the front because this is inside the passenger compartment near the evaporator for the air conditioning system and it is going to plug into our very top electrical connector on the junction block okay so just a quick review of the front of the vehicle we've got power coming from our rapid splitter feeding our high power distribution module it feeds all at the same time the cabin compartment heater cabin air heater the dc to dc converter the battery coolant heater the air conditioning system compressor and the inverter assembly for the front motor of the all-wheel-drive version of the Model S so that gives us one two three four five six seven eight nine ten high voltage components that we have connected 74 feet of high voltage cable to or let's see what was the equivalent in meters sorry I'm still having to remember to say meters 22.56 meters of high voltage shielded cable now this may or may not surprise you but all of these high voltage components that we've just looked at are also found on almost every other electric vehicle and plug-in hybrid vehicle that's out there i could take you over to a wall where I've put all the Chevrolet Bolt EV high voltage components and it has every one of these with the exception of the front inverter because it does not have an all-wheel-drive system but it has everything else that you see here it's different shape size different power levels but it has these same common components and you may have noticed that in on my parts I have common components numbered one through whatever for the number of components and so I'm trying to show my students this is a university these are automotive technology classes i'm trying to show my students and the public that even though it's a tesla it still has the same parts as a Chevrolet Bolt EV so I know this has been a long video we could easily spend a whole bunch of time on every one of these high voltage components which i actually do we offer some online training courses and a five-day boot camp course and if you look in the video description text there will be a link to obtain more training if you would like actual college training and to come to campus right here be here with me in this very shop and explore all these components and get into the diagnostics and actual functional tests and so on we offer all of that what's coming up next we've got the front electric motor for the Model S coming real soon and then the two electric motors for the Tesla Model 3 and then all the Tesla Model 3 high voltage components just like this I think you'll be pleased as to how much wiring they removed on the tesla model 3 versus the model s it's it's radically different all right.
