Max Charging %

[Loosehead]

Hi all,

Read a few threads but can't see a definitive answer.

My ZS EV doesn't respond to the app when I try and move it out of long trip mode. Another thread says that the standard range should be charged to 100% as often as possible. Is this correct?

TIA

It is a good idea to balance the batteries once a month especially if you do a lot of rapid charges.
I have my battery between 80-90% each morning for my commute and balance roughly once a month at the weekends but I dont do a lot of rapid charging.

I'm sure someone will add some further detail, but...

My understanding is due to the different battery technologies. The SR, battery health is better longer term to be charged to 100%.

On the LR, it is better maintained to an 80% charge.

I think all SR do this, mine is the same as yours, drag the slider to 80% and it looks like its sending this info to the car but it never sticks, i also notice everytime i go back into the app it briefly shows the slider bar 80 before going back to 100%

Yes
SR 100% every night if you like
LR 80% most of the time 100% for long trips or randomly for balance charge
I know it sounds strange but the 2 batterys are made with different chemistry

Yes the short range has different battery technology - which is happy to get a full charge every time.

I wonder why the long range has different chemistry.

I would imagine that the chemistry that does not degrade even if charged to 100% every time, is more expensive, so it makes little to no sense to put that in the "cheapest" variant.

Do we know if the LR has a problem with 100% no matter how it is applied ?

I know fast charging will degrade the battery faster than "slow charge".

I wonder if the battery is less degraded if charged to 100% with a granny charger, as opposed to a fast charger.

My home charger never goes above 3KW so essentially charging "very slow". (Not a problem, the car spends a lot of time in the driveway, so plenty of hours to get to "full").

The energy density is different and why the 2 models weigh about the same yet the LR has 20 kWh more storage.

It's actually the SR has the cheaper battery density isn't as good and worse in cold conditions

I have experiened the SR ignoring charge level request. I feel it would really should let my SR to charge below 100%

why? I have gotten so used to regen braking that not having when the battery is full has nearly caught me out a few times. I now expect the car to slow by lifting the accelerator, when it doesnt it is a surprise (bear in mind this will be early in the morning and brain not necessarily fully engaged )

I nearly always charge overnight at home. I can do the maths and work out how long to charge for as there is no API for Ohme to talk to, but I feel thats unecessarily painful to calculate and configure

 

[N2STY]

Yep that's one of the disadvantages of the SR
