I have a Wallbox charger. I don't do many miles. I'm on the Octopus Go tariff (4 hours off-peak, 20 hours peak).

The Wallbox app allows me to turn down the amps supplied by the charger. Is it better to AC charge slowly provided I can still get the battery charged sufficiently in the 4 hour off-peak period? I'm assuming that any kind of charging put strain on the battery, so the more slowly I charge the better... but sometimes the obvious isn't correct.

I read that lowering the rate doesn't help your batteries in any significant way. It also doesn't help with efficiency as the charger is actually less efficient at partial load and most efficient at full load.

The single phase internal converter allows only 6.7kW so no need to reduce anything to save the battery.
OTH, no need to have the Wallbox give more than 7kW either!
