A reverse engineered interface for the BMW i3 Electric Car, created initially by Terence Eden, with some code modified by Quentin Stafford-Fraser.
These API calls are designed to allow you to interact with your BMW i3. They were reverse engineered from the official BMW i Remote Android app.
Your use of these API calls is entirely at your own risk. They are neither officially provided nor sanctioned.
THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.
There are three API servers.
https://b2vapi.bmwgroup.cn:8592
Chinahttps://b2vapi.bmwgroup.us
USAhttps://b2vapi.bmwgroup.com
Europe / Rest of World
In order to authenticate against the API you will need to be registered on BMW's Connected Drive service.
You will need:
- Your ConnectedDrive registered email address.
- Your ConnectedDrive registered password.
- The i Remote API Key.
- The i Remote API Secret.
You can get the i Remote details from either decompiling the Android App or from intercepting communications between your phone and the BMW server. This is left as an exercise for the reader ☺
Firstly, we use Basic authentication. That means taking the API Key and Secret and Base64 encoding them.
So key:secret
becomes a2V5OnNlY3JldA==
We also need to send the following parameters as
Content-Type: application/x-www-form-urlencoded
grant_type=password
&username=whatever%40example.com
&password=p4ssw0rd
&scope=remote_services+vehicle_data
Here's how to do it with curl
:
curl \
-H "Authorization: Basic a2V5OnNlY3JldA==" \
-H "Content-Type: application/x-www-form-urlencoded" \
-d "grant_type=password&username=whatever%40example.com&password=p4ssw0rd&scope=remote_services+vehicle_data" \
"https://b2vapi.bmwgroup.com/webapi/oauth/token/"
If everything has worked, you should get back the following JSON:
{
"access_token": "RCQ1hLP4AFaUBW9BjcPUN3i4WgkwF90R",
"token_type": "Bearer",
"expires_in": 28800,
"refresh_token": "7WgKmEJ2kD1ydl9Hefp01eS8qDGzKnzjeORpA6vtsoFIEanz",
"scope": "vehicle_data remote_services"
}
You must include
Authorization: Bearer RCQ1hLP4AFaUBW9BjcPUN3i4WgkwF90R
in your headers with every request.
The expires_in
is in seconds - giving you 8 hours before you have to renew the token.
I've no idea what the refresh_token
is for. Once the access_token
expires, you can simply re-authenticate and gain a new one.
You must include
Authorization: Bearer RCQ1hLP4AFaUBW9BjcPUN3i4WgkwF90R
in your headers with every request.
/webapi/v1/user/vehicles/
- Remember to include the
Authorization: Bearer
header.

Sending information to the car is slightly complicated.
Your app communicates with the API, the API then communicates with the car's 3G modem, then you have to wait for a response.
If your car is in poor coverage, you can expect significant latency. Often much higher than a typical timeout will allow for.
At a basic level, you can just send a request - for example to lock the doors, or set off-peak charging.

These commands are all available via the API, but may not be supported by your vehicle.
These are just what I've discovered so far.
Data must be POST
ed to the server.
If the vehicle is plugged in, but not charging (due to an off peak setting?) it is possible to force the car to charge.
serviceType=CHARGE_NOW
This will activate climate control within your vehicle.
It appears to be limited to the last temperature you set when you were in the car. I can't find a way to instruct the car to reach a specific temperature.
serviceType=CLIMATE_NOW
Performs central locking.
serviceType=DOOR_LOCK
This will unlock all the doors on your vehicle.
Please use extreme caution when sending this command. Ensure that you are in sight of the vehicle and are able to lock it if needed.
serviceType=DOOR_UNLOCK
If you recievce an error after DOOR_UNLOCK that looks like
{"error":{"code":500,"description":"(SmartPhoneUtil-A-2013) Action is forbidden. secretKnowledge is missing but required!"}}
An addition field must be included
serviceType=DOOR_UNLOCK
bmwSkAnswer=BMW_ACCOUNT_SECURITY_QUESTION_ANSWER
If you can't find the vehicle, or need to illuminate something in its vicinity, you can briefly activate the headlights.
serviceType=LIGHT_FLASH&count=2
- I assume that
count
relates to the number of seconds to keep the light on?
- I assume that
Set the peak / off peak charging schedule.
serviceType=CHARGING_CONTROL
- Additional data needs to be sent as parameter
data
in JSON format. The data itself is the same as returned by Get Charging Times. - Instead of
weeklyPlanner
twoTimesTimer
can be used. Format of data currently unknown.
