I really do have a problem with this recommendation from MG but only on the LONG RANGE model and would be extremely grateful if somebody can explain to me why I have wrong ??.
We know and understand that the battery chemistry in the standard range is completely different to that in the long range version
.
In the standard range model you NOT able to set a percentage charging level, you have to charge to 100% every single time, so therefore as you are likely to leave the car plugged in and go on to commence a HV battery balance / equalizing cycle ( same thing, different name ).
The long range has a different chemistry and that MG recommends that for daily use and shorter trips, you charge the battery up to 80% and then ONLY charge to 100% level for longer journeys to assist with long term HV battery life
.
Okay, I can totally understand and see the point of this recommendation due to battery chemistry.
However, as we already know a balance charge can NOT commence until the HV battery has reached 100% fully charged.
Now compare the above MG recommendation of :- "In order to maintain the health of the high - voltage battery pack, the customer should carry out equalizing charge once a month".
Then that is contradiction in terms, on the long range model surely
?.
So, if by charging to 80% SOC on a LR totally suits the customer needs for the majority of their usage, why are you then having to follow guidance to then charge to 100% and balance at least 12 times a year to satisfy this advice, I clearly see this as contradiction in terms surely ??.
They both don't work hand in hand really, do they ???.
Restrict your charging to 100% to maintain the health of your battery
followed by charge 100% once a month to perform a balance
.
Surly it has to be an incorrect "cut and paste" exercise and applied to the LR model ?.
Which is not uncommon in the manual as we know.
