Mothballing an EV

[Venisonpie]

I need to park up a handful of Renault Kangoo's for 3-6mths, has anyone got any tips on how best to look after the batteries?

Do I trickle charge them?
Do I charge them and leave them?
Do I run them flat and leave them?

Any input gratefully received.

If they are anything like the i3 then charge and leave. It advises not to leave empty for prolonged periods of time so I'd imagine Kangoos to be the same.

If I'm not using the Tesla for a while I leave it plugged in and floating at about 60% state of charge.

can you set a charge limit, whats the vampiric loss on them like?

best stored 40-80% charged, dont plug them in and leave them at 100%

We've had an eNV200 parked up in one of our workshops whilst we are designing a new electric refrigeration to work on it. Before last Friday I think the last time we turned it on was 3 months ago. It started and ran without a hitch. Our experience is that the 12v battery tends to cause more issues so I'd put this on a trickle charger if you can.

If the cells are anything like the ones we use for electric R/C racing then storing them partially charged is best for longevity.

Nissans are best stored around 50% of charge. As far as I am aware even 80% is OK, and never less than 20%.

Many second hand Leafs coming into NZ from Japan have clearly been kept at 100% as they can have low mileage with significant loss of battery capacity.

The lead acid battery is best kept at 100%.

Any idea if there's any need to put a tender on the 12v battery? Will it automatically top itself up from the main battery?

it takes care of the 12v itself

as said set the bat to 60-80% and leave it plugged in

Actually, even if the car has been charged to 100%, and is left undriven for prolonged periods - (I left mine for two months), I found that the leaf 12v battery had gone flat and I needed to re-charge it (that was despite the solar panel on the rear wing).

Best advice is to maintain in 50-80% window. Fully charged degrades the cells and flat damages them, irreparably.

Probably only sorts out when charging.

Nissan EVs top the 12V battery up as needed. If you see all 3 blue lights flashing on the dashboard that's the 12V battery being charged.
