My Rolec works fine, do you have another dealer near you that you can seek advise from or email MG head office
 
Hi srobo2,
I wouldn’t worry about going to another dealer if you don’t have confidence in the one you purchased it from, I’d make a point of telling them..
My Rolec works fine on delayed charging, but with the EV energy app I merely put the time in of when I want the car charged.
My car will not charge with the doors unlocked at this time, it needs the BMS update, as I bought my car in March and it’s only had the comfort 2 updates.
Car has now completed just over 11k and therefore will be in for its first service in a couple of months...
 
I'm sure I read on here that there was an issue with Rolec chargers/ev.energy app and timed charging and that a software fix was required or on the way. I can't find it now :rolleyes: Have you tried contacting ev.energy support?

Edit - found it: Octopus Go or Agile
 
Not 100% sure but, from what I have read I think the update you need is:

EVCC (Electric Vehicle Communication Controller)

Following this update you should be able to AC charge with the door unlocked and carry out a timed charge with a Rolec......

Is that an update to the car or Rolec charger? Thanks :)
 
Smart charging can be difficult to set up, but it can be done with a lot of perseverance!

3 weeks ago I posted here as I was due to get a Rolec charger installed and I had concerns as I could see that there could be issues. Now I have finally got it sorted thanks to reading the advice in this forum, a software update from Richmond MG in Southampton, many e-mails to ev.energy and Bulb my energy supplier.

So, where do I start? to be continued...
 
1st. Update your ZS software. I booked mine into Richmond MG Southampton 3/11/20, they really listened to me and understood what I was talking about. I told them I had a Rolec charger and that I had charging issues and that I read on the forum that there is a BMS updates that can fix it. They have a technician called Gareth who is their EV expert and they said bring it in and they would check if the software was up to date even though I only got the car on 21 Set 20 and it already had the Comfort2 update.

As they recommend Rolec Chargers I asked if they would do this free of charge and they said yes under warranty. They contacted MG technical who authorised EVCC & OBC updates applied to my car. I told them that I wanted to post what the updates where on this forum so they kindly supplied me with this...

EVCC - Electric Vehicle Charge Control
Improves compatibility with smart and timed charging systems that use PWM wake up strategy (e.g. ROLEC Smart EV). When the customer connects the charging gun to the vehicle, a timer is started within the module. This allows a charge to delay the start of charging session for upto 10 hours before the EVCC module will shut down completely. If a charge starts but then stopped within 10 minutes the timer restarts.

If the charge starts and continues for more than 10 minutes, the timer will simply run for 10 hours from when the charge gun was inserted.

The charge timer will not terminate a charge session, even if the charge is delayed until 9 hours and 59 seconds after the charging gun is connected.

OBC - Onboard Charger
Allows the vehicle to be charged on AC charging stations without the need for the vehicle to be locked. When an AC charger is connected to the vehicle the charge gun will be locked into the socket and charging will start. If the customer locks the vehicle charging will continue.

If whilst charging the customer unlocks the vehicle the charging will temporarily stop, and the charge gun will be unlocked. If the charge gun is not removed within 1 minute, the charge gun will be relocked and charging will resume.
 
2nd ev.energy - check tariff peak times match your energy supplier and ask them to manually switch off trickle charge.

I first realised my ZS had the problem as the Rolec charger did not recognise when I was on peak rate and charged my car straight away and did not wait until off peak. - I could see what was happening on my smart meter. I then had to use boost in order to get a charge even when my tariff was off peak!

ev.energy (after a bit of e-maill ping pong), then told me what my peak times were set up to, of course they were wrong even though I had selected the correct tariff on the app!

They had to update the tariff on the app which took over a week but now it is set up correctly even though you cannot actually see what the peek times are on the tariff you have selected. You can only confirm its right on the app because when you update your Smart charge settings, "Only charge below" matches your peak rate in pence/kWh. I've asked them to show the peak rates on the app and they have made a note of the request for future app updates.

I told them I had my ZS charge software updated so they manually switched off trickle charge. (blue flashing light on the charger now instead of a green)

Good luck to everyone who is having this issue and I hope this helps you resolve it.

Regards

Jason
 
@ScifiArgonaut thanks for posting this detailed information, it will be invaluable to help others understand the software updates and how their car works. Hats off to Gareth @ Richmond MG Southampton for providing the detailed explanation.

Hello, thanks for the information above very useful. Currently if I plug my 7kW home charger in the battery charge status will start flashing up in the instrument cluster - this will only happen if I lock the car - if I unlock the status is "connected but not charging". My dealership has said the High voltage fuse update is done. Just so I have a clear understanding of AC charging whilst unlocked could you describe the sequence of events you experience when plugging in your home charger. I will go back to the dealership with the OBC recommendation. Many thanks.
 
My last two charges with my Rolec charger have shown issues in the ev.energy app - a couple of minutes after connecting the charger and a charge commencing, the app shows the charge has been completed, even though it isn't - car/charger both report the charge as ongoing. Support ticket logged today...
