Racking Up The Charge Counter

goz83

I have an electric shower which has priority over the EVSE. The shower is often used when the EVSE is in use....sometimes mid charge, sometimes after a charge has completed.

I was wondering if:

a) when the car is charging and the shower interrupts the cycle, does the car consider that in the same way as when the car is unplugged and when the EVSE is given power again, would it be considered a new charge and so then add another charge cycle to the total number of charges recorded?

b) the same as above, but after a cycle has ended. I notice when a cycle is over and the shower is turned on and off, I hear the EVSE click the same as if it were starting a new charge.

Why do you care how many charge cycles are recorded? In case it affects the resale value of the car when someone reads out the computer? Or do you think the BMS will work differently if the number of charge cycles is unusually high? I wouldn't worry about either too much.

I would care a lot more about having a nice shower, so get rid of the electric one asap

In general it's better for the battery to have lots of shallow charges as opposed to fewer 0->100 charges so number of L1/L2 charges is irrelevant really. The SOH/Hx where it's all at as far as Leafspy number are concerned.

Everytime you hear that EVSE clunk it is another increment on the L1/L2 stats in LeafSpy.

The general wisdom is that the L1/L2 number is irrelevant but I get your concern. I also wondered the same thing once I realised that having the timer on in the car causes the L1/L2 figure to basically be twice what it actually should be (once for when the car is figuring out what rate EVSE its connected to and the second one for the actual charge session).

However, will the buying public know the difference. Will the buying public know how to even use LeafSpy. I guess all you can do is point them to forums like this to convince them that its an irrelevant number or alternatively reduce your level of hygiene!

The figure in LeafSpy that I find most accurate is the AHr figure and even that seems only like an indication rather that being accurate because my AHr & SOH figures go up in winter and down in summer when you would logically expect it to be the other way around.

I was curious rather than concerned. If someone tried to knock money off the sales price due to higher indicated slow charges, I would tell them where to go.

A proper power shower would be nice, but I have returned to education and I am now a poor student, so the electric shower will have to do for now......although I do have a 3.3 bar pump and a Bath Shower Mixer.......so maybe I should look at installing a fixed shower head in the mean time? That's for another forum.

3.3 bar? That will almost take your skin off

Go for it!
