I PUT THE WORLD’S FIRST DC FAST CHARGER IN A HOME! | DAY IN THE LIFE OF AN ELECTRICIAN FAMILY

What happens here

The presenter concludes by emphasizing that while DC fast charging is quicker, it's generally more expensive per kWh than home AC charging (e.g., 20 cents vs. 42 cents per kWh at a Tesla supercharger). It's recommended for emergency situations or when rapid charging is absolutely necessary, rather than as a primary charging method for routine use. For situations requiring mobility and high power, external battery banks or large generators would be needed to supply the 100 amps required by this portable charger.

Goal: Summarize the benefits and considerations for using a portable DC fast charger.

What they say

Hide

home or do it in your office. Yeah. You think it's cheaper um DC fast charging at your house or AC charging or it's all the same cost? >> I I I don't know how efficient this is. Um I would say just doing standard you know, if you can get away with like, you know, a 32 amp charger and just keep them charged all night >> Yeah. Okay. Only when you're in a pinch you want to do this. You want to charge up fast cuz you got to go somewhere. >> Mhm. Um I would recommend using, you know, DC fast charger. >> this is the future really. Yeah, it is. It really is like Yep. Somebody could lose uh their their battery on the road, right? They run out of miles. You bring this. This can just recharge them back up, get them on the road. Yeah, but then what's going to give them 100 amps output, right? So you're better off not using this but having batteries. Yeah. Have batteries already charged up and then you don't need cuz how are you going to feed this with 100 amps? You'd have to bring a 100 amp generator, right? >> Yeah. So that's like a 45 kVA uh transformer and generator that you would need for this guy. >> Yeah, you're going to need a So that's the thing. Yeah, that would be Might as well put this in the van, but how are you going to feed it? Right. You could see it's really working now. Can I touch the screen? It's touch screen. 50% now. It's working. It's pushing. See that kW is chugging in there, man. Look at that, 1.68. 1.69. Mhm. It's a lot of power. It is a lot of power. And it uses CCS. It's It's This charger is different than this one. Yeah, because that one in your hand is only for AC. Yeah. Right? That's standard J1772 Mhm. or the Tesla only has AC on it. Okay, well the Tesla actually does also have DC plugs, I should say. But if you look at it just look at the end of it. So you got your two hots, your ground, your control pilot and then your plug present. >> Mhm. And then here you have the DC also plugged in. So now this CCS also incorporates that J1772, but it's a dummy. Yeah. It's not using it. It's only using the control pilot and the plug pilot. Those two little tiny pins, that's it's using those and uh it's using the two bottom pins. That makes sense. >> for DC. Yeah, this is J1772 and then the uh Tesla uses NACS. So North American charging standard. >> Yeah. What do you like better? NACS. NACS? Yeah. I'm pretty sure that uh every vehicle is going NACS. >> Yeah, they go in so in and out so…
