The climate control is powered directly from the battery, and the battery is charged by plugging the car in. So if you have a charging setup that provides less than 20amps, the car will slowly lose charge while plugged in. 20 amps or more and the car will slowly gain charge if the climate control is run while plugged in, because unless blocked from charging by a timer, the car will start to charge under that circumstance. If the car is prevented from charging, of course, it will lose charge.BeachLeaf wrote:Hi all, while plugged in and using the climate control (but not charging) reduce range?
That is, does the climate control use the vehicle's battery or the power supplied while plugged in. I've been using the app to start charging even though the battery is fully charged, then I turn on the climate control. Wasn't sure if I needed to actually start charging since the vehicle was plugged in. Hope that makes sense.
The car should start charging again as soon as the climate control is activated. Now, about the bolded part above: it isn't a good idea to leave the car plugged in, but not charging, for more than a few hours, as this can slowly drain the 12 volt battery. New leafs seem to compensate for that, but not older ones. If it were me, I wouldn't take the chance...BeachLeaf wrote:Thank you for the responses. I am using a Juice Box Pro 40 and I wondered if the climate control started to take power from the batteries if it would automatically start charging again while plugged in. I suspect there's a sort of threshold of drain before charging would be initiated again.
I was hoping I could set the charge timer to begin charging then have the climate timer turn on the climate control. Seemingly that's not possible, given you have to pick a timer then pick what has priority charging/climate control (that is if I understand how the timers work...)
First, the resistive heater always runs in cold weather to preheat, so that drain should be assumed even with a heat pump present. Now, about the bolded part: the climate control always takes power ONLY from the pack. The pack should always start to charge when the car is plugged in with the climate control running, so I'm not sure what you mean. If you are losing charge with the car plugged in and the CC on, it's because the EVSE isn't providing 100% of what is needed - it shouldn't be that the car is not charging from the EVSE. Are you using a charge timer?jjeff wrote:I always start charging first, then initiate the climate control. Not sure if that is necessary with the newer Leafs but with my '13 if I don't it totally runs off battery and uses nothing from the EVSE, even if plugged in My '12 is even worse in that the only way to use the EVSE and climate control is to use the preheat timer, manually running the HVAC even if plugged in results in 0 amps from the EVSE and everything coming from the battery
As Leftie said, a resistive heater can use close to 20a @ 240v itself(my '13 uses about 18a @ 240v max heat) but A/C will use quite a bit less as will a heat pump heater, especially in warmer weather.
The charge timers have played a remarkable amount of Hell with Leaf drivers over the years. Just for giggles, try turning off all charge timers and see what happens.I do have a charge timer set with a very large window of time - 8:10 PM - 8:30 AM with the cc timer to come on within that time window. Seemingly, once the car is fully charged it doesn't matter if the charge timer is set to continue, as there's nothing to continue.
