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 a diameter of about eight millimeters which if you convert it into square millimeters of area turns out to be equal to about 50 square millimeters and then there is an insulator around it and then you can see in the outer layer there is another conductor which is the shield which is to protect against electromagnetic interference and it is covered with a layer Other than the insulation now on the ends of these cables, the shielding connects to a single conductor here at the end of the cable that connects at the end to the car body which is also ground with a voltage of 12 volts, the inner conductor is where the high voltage current moves and provides power to the various components in the car.
Are there different styles:
There are different conductor styles, this is the conductor that connects two pieces together, has a metal terminal in it where there is a terminal that meets the terminal and the tren and makes an electrical connection to transmit current, so let's start our exploration of all these cables and high voltage components with the ones that everyone is familiar with Especially if you are driving a Tesla and this is the charging receptacle, so here in the left rear of the car there is a charging receptacle for tesla sold here in the US Tesla has its own shape of its own charging receptacle but it actually follows and conforms to the Society of Automotive Engineers J1772 standard As a matter of fact Tesla sells an adapter to go from their charging connector to the round j1772 found anywhere other public charging station, so tesla has its own charging stations all over the country, many of which are a great network, but if you can't get to a station Tesla charging, you can connect this adapter, the instructions on it directly indicate to plug it into the car first, then you can use the j1772 charging coupler to connect and charge the Tesla car, which is one of the 11 high voltage components in the car, so I would like you to See here is there two big orange cables here that have a 50mm square conductor cable that lets the current from the charger in.
Comparison between Model 3 and Model S:
Now by comparing the Model 3 which has a higher charge rate, its 95mm cable is gigantic compared to this Model S. I understand that the latest version of the models just announced supports faster supercharging and will have to have much larger cables for this much to pass. The current is through it without heating them up but anyway, these two cables should go somewhere, and if you look inside the passenger compartment, you can see that it goes in and down under the seat into a part called the compact charger unit, so that's a big, long cable here from the bowl. Charging to the charger unit on board is seven feet or 2.13 meters and there are two of them, so there is a large portion of the 74 feet or 22.56 meters cables on this car, so let's see where these two additional components of the two wires are in the charger unit on board by the way, So these are only two of the five cables that are there, uh, this green here is our land, and it is the third one down here, and then there are two small types that are here on this device, and there is one that detects when you have connected the charger which is called proximity detection, and then there is a charger called Control pilot which is for communication between the car and the charger or charger and the vehicle depending on the type of charging we are using, well, we got this big long cable from the charging receptacle now to the charger unit on board, let's look at the charger unit on board in more The detail next, well this big box here is the charger module on the sticker on the label called it a 48 amp single phase auxiliary charger kit and you can see the big poster here, see the second explanation of this for lesson # 2.
