Charging and discharge % recommendations

[kevinpclarke]

I’ve only had my ZS EV LR for one week or so. I duly ran the car down until it reached 20% and charged it up to 80%. as per the recommended documentation/internet info.
I just wondered what the general opinion and experiences was for discharging lower than 20% I.e. 10 or 15% and indeed charging it higher than 80%? Or should I only exceed these %‘s when doing long journeys ?

Any advice would be greatly appreciated.

Regards
Kevin

Up to now I have charged my hybrid every few days. Of late have charged when battery down to less than 20%. Only strange result is that instead of giving mileage of 32 miles now stops at 31 miles ???
Car done some 10,500 miles ?? Any ideas

You don't need to run it down to 20% before charging it's quite happy at charging even if your just adding 20% from 60%

Charging to 100% is fine when you need it just don't leave car at 100% with out using it

The battery will be happy if kept above 20% not so happy under 10%

For best battery health keep between 20% and 90% you can charge anywhere in-between

Hi, what battery type do you have?
The 20-80% thing is just a guide.
I keep my MG5 between 40% and 80-90% and battery balance roughly monthly.

We only charge to 80% in a daily basis and charge to 100% if needing the extra range. It hasn't gone below 32% yet.

We also avoid using fast charging methods, as we've heard that can stress the battery.

It’s an LR. You mentioned Battery Balancing. I presume that is changing to 100% and leave it connected to the charger whilst MG does it’s balancing work? I read somewhere the light within the connector where charger is connected pulses on and off for an hour or so?

Depends on if you use rapids as they charge using DC and you can only balance on type 2 AC can take 20 minutes to a few hours but only at 300W.

I just have a home Hypervolt type 2 7Kw charger which I guess is AC

Yes you guessed right

I charge to 100% every time I come home and allow it to balance every time via a Granny whether I need it or not and after 18 months and 28k plus my battery is still 100% SOH.

Out of interest how low have you run the battery down to?

 

[Barrie]

It has often shown below 15km when I land home !! Never had it on a charger other than at home.

Do you always use a granny cable to charge at home or do first charge it via a home type 2 7kw charger before switching to the Granny cable?

 

[Barrie]

No, Granny only. Just via an outdoor socket with a 30A fused spur fitted by an electrician. We live in France and the Granny pulls a constant 2.2kw so I plug it an after work and unplug it in the morning. My furthest customers for my business live 125km away from me so I always have to have it "ready to go" if needed for a 250km round trip. Sometimes I dont use the car for a few days and it does not lose any charge when I come to use it.

It sounds like you have little option, but to run the charge down to 15km when doing a 250km round trip. It is reassuring to know it will go as low as 15km or more without stopping. I’m still getting used to my ZS, but I imagine I’ll run it down lower than 20% from time to time. Many thanks for sharing your experience.

You can run it to zero and I can vouch for that. There is definately a built in "buffer". I arrived home with 1km showing and zero % once and drove it up and down our road totalling around another 10km until it died. I have a portable power station that I then used to give it a bit of juice to then get me back home ! I dont see the point of an EV with a stated range of 280km when you cant use it all ?

Good grief! that’s impressive! The portable power station sounds useful. Which one would you recommend?

How do we actually check the SOH?

How do we actually check the SOH?

With an OBD reader which you plug into the car and an app.
