What amount of time would you say qualifies for an extended period? Coincidentally 2 days ago I tried the double lock feature for the first time and 6 hours later my 12 volt primary battery died (got the "ok to drive with caution brake pedal feel reduced" warning lamp).FYI ... on the Range Rover (and I assume the I Pace), double lock will run down the 12 volt battery if it is left engaged for extended periods. For long term storage, "single lock" uses the least power with unlocked and double locked using progressively more.
Apparently the power requirements for the motion detector inside the vehicle is not trivial:Once the full alarm system is armed, the alarm system activates if:
- The bonnet, tailgate, or a door is opened.
- Movement is detected within the vehicle's interior, including air currents (if intrusion sensor fitted).
- The vehicle is sufficiently raised or tilted (If tilt sensor fitted).
In this state, an open glass area may cause the alarm to sound, due to the movement of air currents. Make sure that all glass areas are fully closed before double locking the vehicle.
Agree. Seems unbelievable that the 12V battery can be drained when there is a whopper of a battery present.That seems crazy! I'm going to measure the power draw of double lock. When the car is single-locked it draws virtually no power, consistent with the observation that the I-Pace can sit for weeks with not much loss in battery charge.
I am not driving my beloved Kitty much, since about 30 Counties in CA have been put back on shut down by our "lovely" Governor. Does the I-Pace allow for a trickle charger, and if so....where is the hookup? I cannot find it. I am worried about my car sitting for 7+ days at a time and do not want the 12V battery to begin to cause problems on my 100% problem free Kitty. THANKS in advanceAll modern vehicles with alarm systems, even just simple remote control door locks, will have a power draw. The draw will be higher with the more features they have, such as sensors and cameras. I make it a habit to drive every vehicle I have as the "main vehicle" for a day at least once in a 2 or 3 week period. I'll take them for at least a 50 mile drive even if I have no other purpose for driving. I attach a trickle charger to them if I don't plan to drive for a longer period.
Double locking probably isn't going to make it worse. I just double locked mine overnight and it appears to be fine.
THANK YOU. I will just charge the car once in a while, or take a small drive in the neighborhood. My Kitty is safe. We not only live in a 24 hour Guard Gated Community, our 3 cars are parked all day & night in the garage. Thanks so much for getting back to me.Multiple choices to deal with this.
The batteries (remember there are two 12V batteries) appear to get charged when the main battery is charged. So if you plug in to charge the main battery, the others get charged. You can see the auxiliary battery get charged via WattCat.
If the main battery charging is not connected, an alternative is to connect the trickle charge directly to the large 12V battery. This requires removal of the center panel under the bonnet. I don't think I'd go to the extra work of connecting a charger to the smaller auxiliary battery. It is more difficult to access.
Periodically, you could just power up the car to the full ready-to-go mode and let it sit. This will engage the big drive battery for about 1 hour before it shuts down. The smaller batteries are charged during this time as if it were an ICE running and driving an alternator.
All of these suggestions are assuming the car is parked in a safe, controlled area where it won't be stolen or otherwise harmed. Use at your own risk.
It would be easier to just drive the car some distance and smell the less smog filled air (since others aren't driving ICE vehicles) for a while, even if you don't stop anywhere.
I'm not sure if the two 12V are charged while charging the traction battery but they are not charged while the car is sitting unused. Per the owners manual if you receive a low battery alert it recommends you drive the car for 30 minutes at outside temperature of 32° and above or for an hour if below 32°.I honestly had NO idea that charging the main battery ("the engine") charges the two 12V batteries.
