If your car's battery level or status in the VOOL app looks stale — or stops changing altogether — this article explains why, and what actually fixes it.
Where the data comes from
VOOL does not read your car directly. When you link a vehicle, you are authorising VOOL to read the data your manufacturer already publishes to its own cloud service, through our integration partner Enode.
That matters in one specific way: the app shows you the manufacturer's most recent record of your car, not a live reading from the car. If the car has been parked and asleep for some hours, the manufacturer's cloud may not have anything newer than we do, and nothing we can do will make the car report sooner.
How often it refreshes
We are notified when your manufacturer publishes an update — so plugging in, unplugging or charging usually refreshes it quickly.
We also re-check periodically through the day, so the record does not go stale indefinitely.
If it has stopped updating entirely
The usual cause is that the connection to your manufacturer account has expired — a password change, a re-authentication prompt, or a manufacturer app update will all do it. This is expected from time to time and is not a fault in VOOL.
Open the vehicle in the VOOL app.
Remove the car and link it again, signing in to your manufacturer account when prompted.
Check that the car appears with a current battery level.
Linking is not always instant — the connection is completed in the background once you finish the manufacturer's sign-in, so give it a minute before assuming it failed.
Not every car can be started and stopped remotely
Reading data and sending commands are two different permissions, and not all manufacturers allow the second one. Some models can be read but not controlled.
If your car is one of those — or if the connection to it is unreliable — control the charging at the charger instead of at the car. A VOOL charger sets the charging current itself, which works for every vehicle regardless of what its manufacturer allows. Linking the car is optional and mainly adds battery-level information.
If your car is not in the list at all
See List of supported EV brands. Pay attention to the "Integration status" and "Capabilities" columns there — a model marked "Limited" or "Beta" may not add successfully, and that is a limitation of the manufacturer's own interface rather than of VOOL.
