Volvo EX40 2026 Cannot charge car using Volvo App with Hypervolt Pro 3 Charger

Have had numerous issues, multiple chats/calls with OVO CA team, with charging Volvo EX40. Had OCA app and Volvo app car charged fine but was being double billed as running via both OCA and Volvo app. Instructed to remove OCA app and only charge via Volvo app which is connected to charge anytime for 7p kwh rate. Now car will not charge at all even though in Volvo App shows plugged in and ready for scheduled start, wake up 0% added. Now trying to establish if have Hypervolt charger in Plug & Charge or Scheduled mode (no schedule added as set in Volvo app), any help please?

Steve, is you volvo giving you the message (in the Volvo app) that manual scheduling is not possible when smart charging is active (in grey half way down the screen?

Oddly, in car when I look at the main screen, there is an option to adjust the scheduling.

Checklist: 

OVO EV app deleted

Volvo linked to main OVO account (to get 7p) 

Hypervolt app installed - no schedules, linked to the OVO account

Volvo app installed, volvo app tells me that OVO is still controlling scheduling

 

What i’m wondering is if the Hypervolt app needs deleting too?

 

In short this is a mess and like you I’m ready to leave OVO over this. 

The hypervolt charger was checked in a call I had with them, full diagnostics, essentially in this set up the charger is dumb and simply needs to be unlocked and plugged in and is ready to go…. The charging ‘SHOULD’ be managed by the Volvo via there app and set to smart schedule paired with OVO CA to secure cost effective charging i.e. 7p kwh…. Clear issue is non compatibility with the Kaluza platform / Volvo / OVO….. Mine resolved now but looks very messy in the OCA app re charges and cost but have been assured this is just visual and actual billing is in line with 7p kwh when end of month credit applied….

Have had better engagement finally from OVO via email including tech team, latest set up to trial (not done yet) is:

OCA App linked to Volvo only (no charger)

Hypervolt app charger set to Plug & Charge mode

Volvo app linked to OVO account and in smart charge mode ready by 0600

They reset everything so had to log back in and set up as above both OCA app and Volvo app.

    Cool, and on volvo within volvo app set to smart charge finish by xx:xx? When i tried this bizarrely got 1.5 hrs from 1030-1200 and again from 0400-0530, smart charge in volvo app set to finish/vehicle ready at 0530. Believe vehicle went into sleep mode was feedback from hypervolt.

    The Volvo app wont allow me to schedule so I’ve had to do from the car. The Volvo app will allow me to do an urgent charge though. This is so messed up!

    Think I am almost there, OVO have had Kaluza reset everything, then starting from scratch:-

    Volvo App - Link to OVO account when done can see in Volvo app that OVO ac linked press charging button and then under info (i) button displays OVO (assumed PAYG charge anytime already added as an extra in OVO account)

    Volvo App - Set smart charge on and select time to be ready

    OCA App - In devices only link the vehicle (NOT the charger)

    Hypervolt - Set in Plug & Charge mode (NOT any schedule etc)

    Important that for Volvo/OVO/Hypervolt address matches the billing address for OVO account.

    This set up means that Volvo controls charging and not OCA or Hypervolt.
