Will My Electric Hummer Motor Spin?! - DANGER HIGH VOLTAGE!

Today its time to wire up the high voltage batteries to our Electric Hummer conversion. Working with high voltage DC Electricity is extremely dangerous. In todays Electric Humvee video we are going to install the VCU which gives throttle and gear selector commands to the inverter. Kind of important. When it comes time to wire up the batteries for real, we will have 450v with 100kWh worth of capacity. HUGE Thanks to Oshcut for laser cutting my mounts and battery box: app.oshcut.com...

Third: You PREDICTED point #2 way up front by pointing out that this is the first time you've done this, and you EXPECTED there to be obstacles! None of these obstacles have unreasonably slowed you down, and you point out what you've LEARNED from each one of them!

This series has been total gold! Cant wait to see you finally get it rolling. When you make the loom, if you do it yourself theres a lot of great advice online, but i reccomend talc then a fabric strip like fibreglass or a fireproof fabric cut into a tape size strip wrap it around and . Talc inside to stop chafing of cables the fireproof fabric around the entire loom, Then tape it up like a handle of a tennis racket for example then put it in convoluted tubing. At the cable ends terminations etc. Use dielectric grease or at a punch vaseline use it around all your headlight connectors and every other electical termination or join. It will keep rust water and crap out of your connections. Not sure about the High voltage side of things but in general 12/24v evert offroader ive ever rebuilt ive done the same and it protects the loom and everything else. Id assume dielectric grease would be ok just check the spec sheet.

[@LMojzis]

There are many many things that are technically something, but he chooses to use wrong terminology. Like open circuit (O.L) somehow "flowing power". It's like hearing coworkers looking for a 500mA charger because they are afraid to "push more current into their phone, than the phone would accept." I attribute this to Zach trying to do this a) unscripted and b) attempt to use "laymen's terms."

[@sniperlif3]

I would recommend going back through the wiring and add a waterproofing so that you can go through more water if something leaks into the passenger area. Might as well go all the way for future protection. Not to mention, making the top of the hummer a solar array (if there aren't plans already), get that passive charge going for emergency use and to increase range.

[@playerroku4412]

Solar panels on car roofs always sound like a great idea but it won't provide much charge to the batteries.

[@rishusharma1630]

in addition to that add an straight horizontal wire being perpendicular to the forward motion of car. Add many of them in series and use like 20 m of wire. Then if the car moves in any direction except N-S or S-N it would generate potential difference. In best scenario when the car would be moving in an E-W or W-E direction it would cut a magnetic field of 50 micro Tesla and generate a highest potential difference of about 0.1V if car travels at 100m/s 😂😂. I know that's highly inefficient that it won't be able to even turn on an LED but i just want to try this once, but i don't have anything to do that 🙂🙂

[@kingarthurthe5th]

The solar panels would be better for the 12v system than the main battery.

I came here to ask the same question. It doesn't make sense.

[@falconeagle3655]

Cause the programmer didn't add another if condition.

[@jfbeam]

Safety. It's common practice to back with your foot on the brake. (and torque is limited in reverse.) EVs aren't like ICE cars; they have almost zero rolling resistance from the motor + transmission, so without brake or motor torque, they roll very easily. With the brake at "100%", [in drive] road vehicle rules say it must not apply torque. (I call it the Prius Rule(tm).) (and for the record, there are a lot of idiots that drive around with their foot on the brake.)

[@albinekb]

@@jfbeam wouldnt it be safer to have at least two steps in the break, fully pressing it down should not allow any movement, not even backwards (so you acidentally dont back anything over and can quickly stop)

DMV doesn't care what powers it. You register it like it was still gas powered.

@@vidznstuff1 I know they are liquid cooled. The issue I am not seeing an answer to is that they normally are laid out flat, not stacked. I am worried they cannot reject that much heat when stacked. Just asking if that has been thought through. I would think there is plenty of space to arrange them on the chassis to be more apart as to stacked tight.

[@likebot.]

Imagine if you hadn't forgotten about the brake switch and it went in forward anyway? Then when time came for the ground strap to become important you'd have to tear the whole dang thing apart to find out why you only had reverse in a year or two from now. I call that serendipity right thar.

Imagine if Zach updates the dated interior (I know that some people may like it to remain raw) and also painted the Humvee black.....

Hand movements when camera is in first person reminds me of Chris Fix. Love it!

[@a.alg0hary549]

this series feels like: HitMan Building a E-Tank in his garage

[@soberfreund]

With the help of Tony Hawk

[@dasalekhya]

more like *Hitman got married to beautiful lady* ... and then Mrs Hitman said *_you better find a new occupation_* ;-P

[@chickensfloat7427]

"Eventually we will have all the wires managed very well" Coming from the guy named jerryrig everything 😂

Did anyone else notice that he was wearing a MKBHD. tshirt?

[@andrewvader1955]

Dude! That amount of help you need for this project I beat you didn't see this coming! Best to do it with buddy's!

[@chief523]

Loving the series. Do you have a plan to install an emergency disconnect for any firefighting operations? Hopefully it’s never needed but could save a first responders life if you’re ever in that situation.

[@jfbeam]

Look on the table with the batteries. There's a big disconnect switch sitting there.

[@chief523]

@@jfbeam Thanks, I didn’t recognize what that was

[@gwpsr58]

Zach should start every episode with "Welcome, my name isn't Jerry. Really."

[@VamsiMohanKrishnaVadrevu]

This is such a fantastic series. I can't wait for the next one in this. Stop teasing us and just show us if it works Zack! Give us the big reveal. Destroy all the EV companies.

Congratulations! Cannot wait for you to finish and publish the details
