[legacy] My car isn't charging as expected

Person plugging a charging cable into an electric vehicle

If you notice your car isn’t charging quite as you expected, there are a few common culprits.

Schedules set in the car

Some manufacturers allow for basic scheduling or timers to charge the battery which can be configured in the car settings. If you have set a schedule in your vehicle, this will conflict with any schedule set in the Ohme app and result in the car not charging as expected. We recommend you disable any schedules in the car itself to allow Ohme to control your charging.

Charge rate limited

Your EV may include a setting to adjust the rate of charge. This affects the speed at which the battery can be charged. If the rate of charge has been reduced in your EV, this will result in Ohme charging your battery at a slower speed. For maximum speed, you should choose the highest rate of charge your car provides. Please refer to your manufacturer’s handbook or online FAQs for more information on how to adjust your EV’s charge rate. Please note, Ohme charger’s have a max charge rate of 7.4kW / 32 amps.


Your Ohme charger contains a built-in multi-carrier SIM that connects to the internet and communicates with the Ohme app via the Ohme cloud. When the Ohme charger is plugged in, it will check the Ohme cloud for any active schedules that have been set within the Ohme app. You’ll be able to see which schedule has been selected on the Dashboard of the Ohme app. 

If your Ohme charger is not connected to the internet, it won’t be able to select a schedule. Instead, it will simply charge your car until it’s full (or you un-plug).

If you continue to experience issues with connectivity, please head here to see what to do if your charger is offline.

No schedules set in the Ohme app

When you first set up your Ohme app account, you’ll notice two pre-set charge schedules, ‘Every Morning 70%’ and ‘Afternoon Commute’. You can edit these schedules by tapping on the name and adjusting the settings to better suit your charge requirements. Alternatively, they can be deleted by tapping on the name and then the bin icon at the top right of the screen. 

If all schedules are deleted in the Ohme app, your Ohme charger will create a ‘Charge to full ASAP’ schedule. This means it will simply charge your car until it’s full (or you un-plug).

Charging outside of your tariff’s reduced rate

Ohme will always prioritise charging at the cheapest times based on your selected energy tariff in the Ohme app. However, if you have set a schedule to charge to 90%, but only 80% can be achieved in the cheap period, Ohme will continue to charge outside of this to ensure your car reaches 90%. 

If you only want to charge at the cheapest rates, you’ll need to set a price cap. Find out more about setting a price cap here.

Power-Line adaptors stopping charge from starting

If you have power-line adaptors at your property, they may be creating noise on your electrical circuit which can interfere with charging. A power-line adaptor extends your home’s wired and/or WiFi network (LAN/ WLAN) by harnessing the building’s existing power cables.

Please remove the power-line adaptor and perform a power cycle/reboot of the Ohme charger. More information can be found here.
