In this video, I used a 2,000 watt inverter because it's one that I already owned and used for other projects. For many electric vehicles, the maximum continuous power they can provide through the 12V system may be around 1,200 watts. Because of that, a 1,000 watt inverter may be the best choice for an inverter DEDICATED to an electric car setup
Consult your inverter manual for detailed information on what size cable to use, cable length, and voltage drop. In general, SHORT and THICK cables are best for the high current from the 12V system.
The 2023 Bolt EV specifically has a 130A DC/DC converter. That's approximately 1600 watts, but you want to keep in mind that's the MAXIMUM and that the car itself needs some power to run electronics, the cooling pump, etc. Drawing 1,000 watts is about 80 amps, or a little over 60% of the max rating on the DC/DC converter. At that power draw, the converter should barely even get warm.

This is a great set-up. I have done a similar install to my 2022 Bolt EUV, and it works great! I mounted it on brackets on top of the 12 volt converter/charger, and ran an extension cord back to the luggage compartment where I installed a 20 Amp outlet. It's great for using power tools on the job, or keeping the fridge running in a blackout. The 65 kilowatt-hour battery pack should last several days at a 1500 watt drain.

Excellent excellent tutorial. Upon researching a solution for my own '23 Bolt EV, I came to understand the wire gauges and fuses that the car already has coming from the DC/DC (APM) and from the battery to the Fuse Blocks/Power Steering Module. If you look up 'Power Distribution Schematics' in the Service Manual (some versions are free online), you'll get a great understanding of the layout. That schematic will show there is an 175A fuse on the cable that feeds the Underhood Fuse Block where Ben tapped in. I'm not an EE, but I think the existing fuse satisfies the need for an additional breaker/fuse. Assuming of course you use a 3 AWG or heavier cable. That's because the cable between DC/DC and battery, and the cable that runs from the battery to the Underhood fuse block is 25mm^2 (slightly smaller in cross section than 3 AWG (an uncommon size)). However, an advantage to installing a breaker/fuse rated less than 175A would be so that it can create an open circuit before the car's fuse does. The last thing you would want would be a 175A+ surge that bricks your car until you can replace the 'X50D Battery Distribution Fuse Block'.

Hmmm. You are connecting your load fused at 200A with a 2G wire to the positive fuse box terminal. I am concerned that the Chevy installed cable supplying the fuse box from the battery may not be rated or sized anywhere near the max load you are trying to pull to your outboard DC to AC inverter. What is the diameter spec on the car's + terminal to fuse box cable?

Reason is, the breaker being outside could corrode inside and prevent the action it's supposed to do.

I ended up printing the Anderson mount just as is. I drilled out the one hole for a 1/4" bolt, which matches the 175A connector nicely, and then heated the bolt heat to counter-sink it into the 3D print. Looks good, and nice to have a solid spot to mount the end of the cable. It's a little tighter fit in that location than it would be with the 120A connector, but works fine. I added my "make" on Thingiverse.

Ben! Been a while!!! I've just bought a 2021 Bolt that was recalled for the battery and they stuffed in a larger battery and full warranty, top of line Bolt EV for &17,500 with only 3500 miles on it! I've also got an Enphase powered 11KW solar panel system. I see you have some on your garage, I drive by sometimes... Enphase sells a charger that can charge based on solar power output, but also power your house if the grid goes down! Lots have changed since the homebuilt EV's!

Hi Brian! Bolt is a great value for a car! My solar system is 5.4Kw using Enphase micro-inverters. I have a time-of-use plan with our local public power utility. It essentially lets me SELL electricity at peak rates during the day and charge EVs at night at off-peak rates. I installed it myself and it's already paid for itself. A little less than 7 year simple ROI. Come say HI sometime if you are going past and aren't in a rush.

@@BenjaminNelsonX My system was quoted by a solar company that went out of business. I had to finish the system myself, so I bought solar panels and inverters and had to re-work some of the wiring and other systems, but I ended up with the 11KW system for $8000. My bill went from $220 a month to actually getting paid $$$ in summer, then back up to $150 this last month. I have my Bolt set up to charge from 10 AM to 2 PM, when the solar is producing. Otherwise WE Energies does buy my electric (at a reduced rate) and sells it back to me (at regular cost) so in effect if I give them the electric during the day, and charge at night, I'm giving them free electricity. My ultimate end is to have a battery backup and charge it during the day and feed from it at night, reducing my dependence on the grid to as close to 0 as I can get.

Nope. It's a circuit. If one leg needed to be 2ga, then the other does as well. I'm thinking the wire he used is overkill, but you should do your own calculations and understand them before attempting to wire up a system like this. The lengths of the wire matter a lot, in addition to Volts and Amps. Working in the 100A plus range is no joke!

I really like this project. I have been starng at my Opel Ampera-e (= Chevrolet Bolt), while being annoyed that it is a big battery with energy doing nothing most of the time. I also always wondered while Vehicle to grid funtionality has not been standard build in for many years. But that seems to be difficult for several reasons. Just hooking up a powerfull inverter to the 12Volt system seems like a in-between solution. Where I live, in Europe, power outages almost never happen, and if it happens it is only for a short time. So there is no real reason to act on that. But by choosing certain energy contracts you can charge the battery while the grid energy price is low, and sell energy back when the energy prices are high. There is an incentive to do that. The big question is: Can you just hookup such an inverter while there is no power outage? (Or what happens when a poweroutage is resolved? ) That is what a solar inverter does all the time. But is this the same? I guess not. As otherwise Vehicle to the Grid systems would not be that expensive....

You want to keep in mind that the bottleneck is the DC/DC converter. For many cars, that’s around 100 amps. Or about 1200 watts on the AC side. Any more than that CONTINUOUS would quickly run down the 12v battery, and the the low-voltage disconnect in the inverter would then cut the power as a safety feature. A larger inverter gives more headroom for surges and start-up loads.

@BenjaminNelsonX
@BenjaminNelsonX 7 месяцев назад
Electric cars use a device called a DC/DC Converter. (Chevy calls it the APU - Auxiliary Power Unit.) This device takes high voltage from the propulsion battery, and converts it down to voltage appropriate for the 12V system and charging the battery. It serves the same purpose as an alternator in in internal combustion engine, but with no moving parts, noise, vibration, or even needing a belt. DC/DC converters are typically at least 100A.

Keep in mind that the energy really doesn't come from the 12V battery - it's coming from the high-voltage propulsion battery.

@BenjaminNelsonX 9 месяцев назад
You have the right idea that you want high current cables to be as short as reasonably possible. We also want to keep in mind where the power is actually coming from. In this case, the power is actually provided by the DC/DC converter, in this case GM calls it the "APU" Auxillary Power Unit. The negative cable in this installation is connected DIRECTLY to the APU. In this car, it wasn't practical to connect the positive cable to the battery post, as there are already several leads connected there and a mechanical steel cover over the top of it. So, I instead connected the positive at the input to the fuse box, which is only a very short distance from the battery, and the main power connection of the 12V system. There's more than one way to do it, but the main take-aways are to use short, thick cables, appropriate for the amount of current to be drawn.

That seems unlikely. If you are drawing 1,000 watts continuously, it would take over 60 hours to drain a fully charged 66kwh Bolt EV battery pack. The battery would let you run for two and a half day’s continuous at that rate. Assuming that you don’t use as much electricity while you are sleeping, and that you carefully manage what you need to power during a blackout, you could make it last longer than that. Once power is restored, you can charge the car back up as usual. A friend with a Nissan Leaf was without power for 4 days not too long ago. He had no issue powering his necessities with his car during that time.

Thanks for the reply. If you know any one event is coming like a hurricane then you can charge up to 100% beforehand, but for an earthquake you'll probably be at a lot less since few people store at 100% SOC. The key, as you said, is monitoring to make sure battery level doesn't get too low. BTW, my friend in Sunnyvale, CA had a 5 day blackout this year. After that he bought a Tesla Powerwall setup.

Why not hook up to the Main Battery of the vehicle?
@BenjaminNelsonX
@BenjaminNelsonX 8 месяцев назад
Hi Jeff, It's neither safe nor easy to connect directly to the car's main battery. Most modern electric cars have about a 360VDC main battery pack. To start, most inverters are NOT designed to run in that voltage range! It's also a very dangerous (lethal) voltage and can also start fires and explosions if short-circuited. Clearly, manufacturers would NOT want car owners to interact directly with the main battery pack! In fact, there are essentially NO easily accessible points to connect directly to the battery pack on modern EV cars. For cars with DC Fast Charging, the external charger DOES connect straight to the battery, but only after communicating with the vehicle, running a number of safety checks, and then finally closing some high-power relays (contactors) to complete the connection to the battery. We are STARTING to see commercial systems which do allow connecting to the main battery. The primary one so far is a system that allows connecting a Ford F150 Lighting electric pickup truck to a person's home to power it in a blackout. This system requires a fair amount of additional equipment - essentially the same as what you would have for a solar power system, except that the truck itself is the battery. I experimented with my old Japanese electric car, drawing power OUT through the DC Fast Charge port, using a 3D printed adapter and a solar inverter. I was able to successfully draw power from the vehicle, using it as a giant backup battery and convert the power to 120/240V alternating current. Doing this is NOT a project for the Average Joe, but I hope some people enjoyed learning about the challenges of it.

Those hydraulic crimpers work GREAT! If you only ever want to do a single project that needs lugs on cables, but buy some pre-made battery cables from the auto parts store. If you are ever going to do TWO or more projects, get a crimper like this! It supports a HUGE range of cables and lugs.

@@BenjaminNelsonX I want to add Anderson connectors and cable on the back of a couple of my trucks for the winch on my trailer.

@@BenjaminNelsonX Be careful jumping an ICE with an EV, you can certainly use the DC/DC converter to charge the 12V battery, but disconnect it before they try to start it or the cranking amps can overload the DC/DC converter and or damage the 12V battery because EVs generally have lower capacity 12V batteries that are never intended to crank an ICE.

You could just jump from the inverter's negative terminal to the chassis ground of the inverter. One less wire to "forget" to connect.

On the 12V DC side of things it's very high current, that's why thick, short, power cables are needed. 10A at 120VAC is 1200 watts, but the same 1200 watts at only 12VDC is 100A!

Although it's quite easy in theory and very simple to implement, I recommend NOT to do so based on my hands-on experience. My 2015 Fiat 500e was totalled by power surge when I just subconsciously forgot a basic precaution rule: "Never start or restart the car when the add-on 12V inverter is in operation". The DC to DC step down converter embedded with the drivetrain inverter seemed completely dead. That component with more than $5,000 price tag was pretty much out of stock (and salvage parts pricings were also too high to justify uncertain conditions) for this tiny low-volume compliance vehicle. I just destroyed the most cost effective car that I had ever owned; $9k out-of-door with only 22k miles and remaining factory warranty back in 2017.

@@BenjaminNelsonX just corrected what you mention about hybrid, and also that it’s no need it if you have a chargepoint EV charger capable to do both ways like some of the public chargers on our city. I use the EV charger, to connected to my house on power outages without issues. No need an inverter. But I use an inverter on my 2012 to self charge. Installed 2 flex solar panels on the roof and parked, you can use the charge cord to self charge.

Great tutorial, but you still using the 12 volts system of the car. You are not using the 460 V battery of the car. That means that you drain the 12 v battery that it’s used for accessories and start the main electrical motor. I don’t see how you use your car battery. With a 2 way EV charger, you can used like a full battery backup without all this work. Chargepoint EV plus allows you to do it no extra charge. I been using that with my 2017 bolt and using the 460V without problem.

I'm just showing off how I did a project. If a person doesn't trust their own wiring skills, then that's fine. Don't do it. This project uses heavy-duty cables, fusing, and the inverter itself has plenty of safety features. I've tested this many hours running my furnace an other items.

Connecting an inverter like this to your Chevy Bolt is not a good idea. I own a Bolt, and here is why. The 12v battery in the bolt is not charged on a constant basis. The car will periodically check the 12v battery every few hours. By that time, your inverter can drastically lower the voltage of the battery, and since these are not deep cycle batteries, they will shorten the life of the battery. The only vehicle I would recommend doing this to, is a Hybrid car like a Prius that provides constant charge to the 12v battery.

As long as your car is turned on, it will keep up with whatever current you pull out of the battery up to about 110 amps constantly. I've tested this on my 2022 Bolt EUV.
