Supercharging in France

When traveling the Autoroute du Nord in France the superchargers are well placed. When going from Belgium to Paris you can find a supercharger near Lesquin (Lille).

The supercharger is placed at the Novotel hotel parking and while charging it’s easy to go to the restaurant of the Novotel. But nearby are also a Mc Donalds and KFC.

The next stop

The supercharger was not very busy when we passed by and had a full-speed charge. I can image in summertime It might be busy there. When you meet other drivers at the SC you will most likely see them again at the next supercharger at the end of the Peage (toll road) near Arras.

Tesla Supercharging voltage and power ratio

Monitoring my Model X with Icinga does give some detailed insights I haven’t read about yet. When I arrived last night the supercharger (24 stalls) was completely empty. So I was expecting the full blown charge speed. However the battery level and conditioning probably didn’t allow for the full speed charge.

How do the amps and volts move over time?

You can see the voltage did increase slowly over the period of charging, where you can see the power dropped from 94 Amps to 50 Amps the red line shows the battery level which seems to follow the curve of the voltage.

Ealier in the day we see a similar graph but with what appears to be less decrease in power during the charge.

There’s not much to conclude from the data for me now, except that it’s good to see the info and maybe on the longer term understand the times needed and when to start supercharging.

If you want free unlimited supercharging when you plan to buy a new Tesla Model X or Model S then use my referral code as friend of Teslanews.

Tesla firmware 2018.14.2 and what did change

After a lot of news about the latest firmware 2018.14.2 for Tesla it was a suprise last week to finally receive the update. Earlier during the week I had a loaner Model X with a developers version of the software. It appeared a lot snappier in response but I couldn’t find anything else.

No new navigation yet (Europe)

The new software did not bring the long awaited navigation update yet. There have been a lot of youtube videos on the newer navigation but Tesla confirmed last week that it will take some more time before the navigation will be rolled out in Europe.

The update of the navigation seems not to be directly related to the software version anymore. This means we should be able to find maps versions somewhere, but I still couldn’t find that yet. In the API I can see the car version and I will monitor this when the new maps come. For now it is:

[car_version] => 2018.14.2 a88808e

Did I see any other changes? Yes! 

One of the main changes found was that you can now open up trunk and frunk with your app. Nice if you need to put something in your car and can’t access your FOB.

Power saving mode on

The main change that surprised me the next morning was that the power-saving mode was automatically turned on. This is probably nice if you want to save battery usage.

But when you get in your car in the morning to get on your way it is definitely not what you want. The car took about 5 minutes to boot all systems. A call to the service center did help a lot and after switching off the power saving mode it was fixed.

Tesla API with Icinga / Nagios

Before my Tesla arrived I have been looking into the API as published on Apiary which was documented by Tim Dorr . Some excellent work and with a few youtube videos it was quite easy to create my own PHP based plugin for Icinga / Nagios.

What can I monitor?

The plugin I wrote (hacked together might be a better expression) enables me to poll the Tesla API on a 5 minute basis. The information returned from the API is in JSON format and easily parsed with PHP.

The API is clear and simple. At first you need to have a token. This token you can get with a simple request to “https://owner-api.teslamotors.com/oauth/token”

        $client_id = "81527cff06843c8634fdc09e8ac0abefb46ac849f38fe1e431c2ef2106796384";

        $client_secret = "c7257eb71a564034f9419ee651c7d0e5f7aa6bfbd18bafb5c5c033b093bb2fa3";


        $serial_id = "????????";


 // first make sure we get the token


$username = "??????@?????.com";

$password = "???????????";  


        $data = array('grant_type' => 'password', 'client_id' => $client_id, 'client_secret' => $client_secret, 'email' => $username, 'password' => $passwo

rd);

        $header = "Content-Type:application/json\r\n";


        // print_r($data);


        $url ="https://owner-api.teslamotors.com/oauth/token";

        $options = array(

        'http' => array(

                'header'  => $header,

                'method'  => 'POST',

                'content' => http_build_query($data)

                )

        );


        $data_string = json_encode($data);


        $ch = curl_init('https://owner-api.teslamotors.com/oauth/token');

        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");

        curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

        curl_setopt($ch, CURLOPT_HTTPHEADER, array(

                'Content-Type: application/json',

                'Content-Length: ' . strlen($data_string))

        );


        $result = curl_exec($ch);

        $result = json_decode($result);


        $token = $result->access_token;

                

        echo("token: $token\n");

Because I also want to be able to do some analysis later with my car data I decided to write all returned data first to a Mysql database.  The final Nagios/Icinga plugin is just reading the latest record from the table and puts this information into Icinga.

Example data from Graphite (charging power)

For now I focus on the charging information and battery status. The other data (like driving speed etc.) is nice to have and already stored but not yet in use.

Snippet of API request

Using the SQL data exported to Excel it’s nice to have a bit of insight of the charging speeds, levels voltage and power. 

If you look at a longer period of data (a few days) you can monitor the battery usage and charge speeds.

When the wait is over

The hardest part of ordering a new Tesla is… the wait.

Just when you made the best decision in a long time, you realize the pleasure of waiting on something good takes a very long time. The Tesla portal will show you all the different stages of production for your tesla though.

What will happen next?

When you place the order you will see the car appear in your tesla account page. After a while you will get a confirmation on the order. Then a little later you will receive the VIN for your car. This VIN is not always the final VIN since the production time can influence the code sometimes.

Then the wait and reloading of the site begins. You don’t know much until you see that the car is planned for production. Again nothing is sure, and there is no set waiting time known. Eventually the production will start and you know the time of delivery will come closer.

Transport to delivery

If your car has to cross the atlantic the wait is still not over. You will get the information that the car is on transport to the harbour for the crossing. That can take a few days to several weeks. Getting in contact with your delivery contact at Tesla can help on getting a bit more information.

For Europe you will find your car on one of the Maersk lines

Final assembly in Europe

When the car finally arrives in Europe it is depending on your country where it really goes. All European cars (except of Norway and Switzerland) end up in the Netherlands.

Where at Tilburg the battery / engine part will be mounted to the car.  If you have the chance to pick up your car in Tilburg than you will be treated with a small factory tour and a drop-off at the Tesla Pickup line.

Final delivery

When you see your car there is a Tesla employee delivering your car , explaining everything you want to know or you can just opt for thriving out right away.

Let the fun begin!
