My car has a significant design flaw(1), in that it allows children to turn on the backseat car lights and leave them on. I've had more dead batteries in the five years I've had sentient children than I've had in the 40 years prior. This is a great idea.
(1) Perhaps the design flaw is in the children.
- ams6110 11y agoYou have a Honda? The problem is I don't understand how the battery would shut down just lights and accessories without a) losing all your radio presets b) requiring entering the anti-theft code in the radio (risky because if you get it wrong you can brick your radio) c) still have power to know that you're trying to start the car. It seems to me this requires more than internal battery smarts but changes to the car's wiring to have separate battery connections for computer, accessory, and starter. Right now most cars have just one big post clamp for the + and - battery connections.
- sliverstorm 11y agoYeah, it's really a problem best solved at the car level. Brownout detectors shut off all but the most important systems in the car, and then shut off everything when the battery is reaching critical levels to prevent damage.
