The Autopian sits in a SLATE

Plus on an EV halogens would just take a bunch more electricity eventually from the EV battery and range?

It doesn't exactly work like that, the DC-DC inverter on an EV is set to output a specific amount of 12v power, like the one on my Ranger does 1500w, that's it's output regardless of draw, so it has power to run the hi-fi stereo, charge the 12v battery, run the hvac blower and all the lights at the same time, if none of that is on, it's still outputting that power at the ready, it's not like you turn all that off and you get that power back. Plugging in a phone charger or adding some kickass off road lights doesn't really hit the high voltage battery, it may bog down the inverter and cause it to draw down the 12v battery causing other issues, but the draw from the high voltage battery will be fairly steady.

The HVAC heating unit(either heat pump or element) and Air Conditioner are run off the high voltage pack, and those can impact range by quite a bit.

I mean, it really wouldn't make much sense if you draw more power it has to come from somewhere. You can't just create a large amount of power and it goes nowhere unless it's charging a battery instead of powering things. So when the battery would be worn down by the extra load it would demand more from the converter to bring it up to the state of charged? I asked AI for what it's worth.. "Yes, the DC-DC converter draws variable power based on the real-time electrical load of the vehicle's 12V system. It adjusts its output to support components like headlights, climate control fans, and infotainment while maintaining the 12V battery's charge."

It may operate similar to a car alternator with a regulator, but it's still not a big hit to the power, like with my Ranger(which has halogens) running maximum draw of 1500w for an hour is 1.5kWh, on a truck like the Slate that's only 3% of the standard battery capacity, driving above 50mph or using the heater/AC will draw much more than that. So rock those Hella lights on the roll bar and don't stress it.
