Yes I understand. My plan is to install a quick battery disconnect switch, so that when I'm towing the battery is disconnected and the parking brake will not apply itself. This is already confirmed, as I have towed the car 450 miles from Texas, where I bought it.
I typically go to Florida in January, and I like to stop at a Walmart parking lot for the night. This way I can drive as long as I want and stop when I want. No need for reservations at a RV park, no need to arrive early before everyone quits for the day. Also no need to unhook the car if I'm given a back-in spot at an RV park. Now as for heat while parked, The RV uses a propane furnace with a 12V blower to circulate the heat. The 12V blower will quickly deplete my RV "coach" Battery. What I want to do is Jumper the 12V "coach" battery to the Bolt's 12v battery. If the car is off the 12V blower will deplete both batteries, so the car must stay running so that the HV pack will keep both batteries charged. I have already tried this with my other electrics. First the Volt which has a engine for back-up. In the Volt the engine never came on, and the battery draw pulled down the HV pack by 1/3. Roughly got the same result from the Mitsubishi i-miev, pack was depleted just over 1/3 down.
With the Bolt's much larger pack an overnight park should have much less affect.
So when I park for the night, the Bolt would still be strapped to the dolly so It can't roll, and I would reconnect the battery for the night, jumper the batteries, start the car and leave it running all night. Even if the parking brake comes on automatically it's no deal because I'm not moving. The trick is that the Bolt wants to power itself down after an hour of unattended use. I must find a way around this. If that were to happen, then the furnace blowers would pull both 12V batteries down to fully discharged.
I suspect I may be able to use neutral to prevent the car from powering down. However the book says that it should not be left in neutral for an extended period, and if it is the car will put itself in park. There is a mode called "car wash" mode that may hold it in neutral indefinitely. I need to experiment to find out.
GM - Chevrolet..... If you are reading this....The Bolt makes a great Toad for RV use. You can exploit this by creating an "RV Mode" and adding this feature through an OTA update. The "RV mode" would prevent the car's automatic parking brake from engaging and prevent automatic power down unless the pack was depleted less than 6%. A warning screen to pop-up when engaging which would cite the systems to be turned of and ask the user if he/she wanted to continue?
