Boost charging - Everything you need to know

Modified on Wed, 4 Mar at 1:11 PM

What is Boost?

Boost is a feature in the ev.energy app that lets you charge your car immediately at the maximum speed your charger supports, instead of waiting for your scheduled smart charge to begin. Press Boost and your car starts charging right away. End Boost and the app returns automatically to smart scheduling.

When should I use Boost?

You need more charge than your overnight session provided
Your plans changed and you are leaving earlier than your ready-by time
You want to top up quickly before a longer journey
You are checking that your charger is physically working correctly

How to start and stop a Boost session

Confirm the app recognises your car is plugged in at home and that Smart Charging is turned on
Tap the Boost button. Charging begins immediately.
To stop, tap End Boost. Smart charging resumes automatically.

Note
Boost sessions do not count toward reward points. Only scheduled smart charges of 7 kWh or more earn rewards.

Why is the Boost button not visible?

Boost only appears when all three of the following are true: your car is plugged in at home, smart charging is switched on in the app, and a smart charging session is active or scheduled. If any condition is not met, the button is hidden. Check the Smart tab to confirm.

Boost troubleshooting

Symptom	What to check
Boost button is not visible	Car is unplugged, you are away from home, battery is full, or smart charging is off
Boost started but car is not charging	Check for any error lights on your charger or vehicle. Open and close the vehicle door to prevent hibernation.
Boost toggled on and off quickly, now stuck	Wait a few minutes. Try hard closing the app and relaunching it.

Does Boost cost more?

ev.energy does not apply any surcharge for using Boost. However, if you are on a time-of-use tariff such as Octopus Agile, charging during peak hours via Boost will incur peak-rate charges from your energy supplier. For cost-optimised charging, use the scheduled smart charge feature overnight wherever possible.
