Charging with API Support

Choosing the correct type of schedule for your vehicle

All electric cars can be charged with Ohme, but some provide access to the battery state of charge which allows for more precise charging. To ensure you get the most out of Ohme, make sure you choose the correct type of schedule for your car. 

Precise charging support is available for the following manufacturers: 

  • BMW 
  • Hyundai 
  • Jaguar 
  • Land Rover
  • Kia 
  • Nissan 
  • Renault 
  • Tesla 
  • Volkswagen

If you have a car from any other manufacturer, please see ‘Charging without API support’. 

Some car manufacturers provide an API (Application Programming Interface) which allows access to information about your car via your manufacturer’s smartphone app. Providing your login details in the Ohme app allows Ohme to see your car's current state of charge, which is then used to work out how much charge you need. 

To get started, download the Ohme app and create an account. For guidance on creating an account with Ohme please see our tutorial ‘How To: Set Up Your Account’.

You'll also need to download your car manufacturer’s smartphone app and create an account. It's a good idea to make a note of these login details as you'll need these later.

When selecting your car manufacturer in the Ohme app, select the 'account sign in' option and enter your login details when prompted.  Now that you have connected your car manufacturer account, and Ohme has access to your car’s state of charge, it’s time to set up a 'Charge Schedule’. Here is a handy tutorial ‘How To: Create a Charge Schedule’. 

Having access to your car’s state of charge means you can set up a Charge Schedule with a target percentage or mileage. For example, you can create a charge schedule for 80% charge every day by 08:00. 

If Ohme can't retrieve the car's state of charge, we'll assume the battery is at 0%. Typically, this will mean more charge will be added than than you might be expecting. For more information, please see our FAQs
