[EVDL] Bolt battery power?

A front cover article in the National Ham radio magazine promoted the value of the EV for mobile radio operating during drive-everywhere-contesting. But to my surprise, he recommended NOT connecting to the Bolt electrical system due to concerns over dealer warranty issues if anything was connected

Re: [EVDL] free piston generators

I assume in this sentence you meant "plugin-hybrid": "The greater the EV range that a hybrid has, the bigger the improvement." Hybrids don't have "EV ranges" unless 1 gentle mile or so is considered "range". During my EV eganguelising I am forever correcting people who think a hybrid is an EV. I

Re: [EVDL] J1772 vs Nema flat blade insertion cycles for EV

Easy way to tell (maybe) is to open it up and see if it has a conventional small 60 Hz transformer to power its internal 12 V electronics. If so, 240 VAC will likely overvoltage those low voltage circuits (operating at 12 V). On the other hand, if it does not have a small 12 v transformer, then it

Re: [EVDL] Tesla question for Phil

When the refer defrost strip-heater kicks in and my house is on the 1.5 kW inverter, it drops the load and we go dark. But then simply cycling power restores is because the drop of power resets the "energy-star" design will NOT let the defrost come on when power is restored, so you probably get an

Re: [EVDL] Projects -- basement ground-source

The cheapest DIY ground-source heating is to hang an old Air Conditioner from the floor joists of a popular central room in the house and cut a hole in the floor to connect the hot side of the AC to the room. The cold side remains in the basement air. A 10,000 BTU AC unit becomes a 20,000 BTu heat

You hit the nail on the head. The migration of all our high-power systems to HV DC is the topic of my book (EV's, Solar', heatpumps, and all modern power supplies). Any power device that uses "variable speed" such as new airconditioners and other appliances are internally using 365 VDC which is a
