MG5 Instavolt charging problems.

[gaberone rex]

Anyone getting a very low charging rate with InstaVolt rapids? At Stroud Park (M40 at Banbury).
Currently it’s taken 10 minutes to reach the heady heights of 29kW having started at 23 kW. This is the second one I’ve tried here, with the same issue.
Can see other cars are getting around 90kW. Is it the MG5 (20-22) or bad luck with the charging points, I wonder…?

What's your battery SOC at time of plugging in?

From experience, plugging in at 30% in this cold weather yields under 40kW charge rate. Around 10%, mine maxes out around 55 kW in the cold.

Update: I think it’s these ‘ultra-rapid’ chargers actually!
There’s a Leaf getting 18 kW, an MGSV on 62 kW and an Audi on 100 kW. The place is only half full

Thanks. I wasnt aware of that difference. Soc was actually 56% on starting charge though.

Re my update above I think it must be the variable charging points. But not ruling out the bitter cold today as a possible factor affecting us all!

Starting at a higher SOC has a huge impact on the maximum charge speed you'll achieve, even in ideal weather conditions.

Starting between 10-20% with a pre conditioned battery will get you the fastest speeds. Particularly at 50% or higher, you will be lucky to pass 40kW.

My last stop was at a Tesla charger in 14 degree conditions with 53% charge remaining, and the maximum speed achieved was 37kW.

I've reached 80kW on one occasion when charging from 12% in the summer.

Of course,, the charging hub you're at may still have issues.

Can you elaborate on how to achieve that in freezing temperatures?
