    Obstacles in the Way

    Yeah, that's what I was getting at. I guess I didn't explain it well.. Agreed. I think we're averaging 3 days total of power outages on average over 10 years where I am (US - CT.) It's part of why I'm going solar with storage. I'm planning a Sol-Ark w/ emp / solar flare protection.

    Obstacles in the Way

    This is the challenge of the old systems trying to handle evolution of power generation. These wholesale systems should be able to almost instantly tap residential / business battery storage to fill the demand. Not as an on off switch but as a power request. Big generators can bid on demand too...

    Obstacles in the Way

    Can you explain further? I'm missing why it would be unviable. RT is? Roof top? A lot of areas in the US are moving to require battery storage to back feed power. If these 50% renewable power "generators" can also have storage they can help support the grid and even supply other consumers if...

    Obstacles in the Way

    The power companies have lost 25% or so of their customers in a way. They (or government depending on where) still have to maintain transmission infrastructure and keep the grid stable on top of making energy. They likely profit off reselling energy they buy from their solar consumers, that...

    Obstacles in the Way

    This thread wasn't a debate about global warming / climate change, or at least it wasn't until this post, My hope for this thread is that you will stop dragging this post in that direction and that others will stop taking the bait. I find this original topic interesting, but not the off topic...

    Obstacles in the Way

    Hillhater, consider not trying to win every conversation. Try to understand the other persons position and why they're there. Negating things with false equivalencies isn't honest, fair, or constructive. It's trying to shut down info because something disqualifies that information in your...

    Obstacles in the Way

    I'm seeing the iea link not as a report, but more a cost analysis with sliding scales for adjusting for different cost inputs. If you slide the discount rate to 1 (why not 0?..) nuclear falls to more expensive than hydro, wind, & solar. This is probably meant to show different cost inputs to do...

    Obstacles in the Way

    Let's not turn this discussion into a dumpster fire. This isn't about global warming / climate change. I'd love to get back on topic and hear about some spent nuclear fuel storage / reuse that makes sense..that also doesn't burden future generations with our likely short sighted choices.

    How Safe this TVS Diode?

    If it's just the inductive spike you're worried about from say a motor disconnection mid battle, a good sized TVS should be fine handling that by itself. If the motor is AC / bldc the diodes in the mosfets likely would handle the flyback from a disconnect as long as they're decent. If you're...

    Obstacles in the Way

    Thanks hillhater, but a graph isn't a source. Without a source and references the info in the graph could very easily be manipulated, cherry picked, and / or lots of graph fudge added to support any desired outcome. When there are words added to the graph to tell you what to think about the...

    How Safe this TVS Diode?

    I would think you'd want a bidirectional TVS but it depends on how you're implementing this. TVS are good for quick overvoltage (transient) events like a static shock or quick inductive spikes. They don't do so well dealing with long term overvoltage current but are fast. You could look at...

    Obstacles in the Way

    I'm aware of the ugly side of oil and gas. They are unfortunately the most portable and pourable currently and what most things are built around. I see getting the world off of oil would get some (to a lot) of the power away from some of the psychos running countries / starting wars. Coal...

    Obstacles in the Way

    Costs are not just monetary. Safety, environmental impact, accidents, hackers, waste storage, etc. all should be considered. To look at things objectively you need to try to remove fear. The things that trigger fear are legitimate concerns and should be worked in as issues. I like safety 3rd...

    Obstacles in the Way

    Geothermal power is something I believe will be one of the better renewable options once it can scale up. Think of it like a nuclear / gas / coal plant without the ugly issues belonging to that heat source. Uses heat in the earth to make steam / make power day and night. It can use abandoned oil...

    Excellent blog post about TSLA as an investment by Jack Rickard

    There were definitely words there. That was one of the hardest things I've ever tried to follow. I see people investing in Tesla at these insane prices as very similar to people investing in crypto. Push / buy into the hype, the price goes up. The actual value is? Tesla build quality is about...

    reduce voltage drop between battery and controller

    Think of electricity as water. A capacitor is like a water tower. Voltage is like water pressure. Amperage is like water flow. Lots of flow (lots of amps) bigger pipes required (bigger wires.) A capacitor helps a pulsed load receive a more constant voltage supply. They also can absorb some...

    Best connection method nickel strips <-> cable

    I don't have any BMS recommendations (I assume you were asking me.) You could try to work in the BMS on a side of the pack so you can access the cell group connector, this would be win / win. Use the same connector for the BMS and manual intervention. It should also allow you to swap out the...

    Best connection method nickel strips <-> cable

    You are asking about a second set of wires to manually check / balance the pack, correct? If your BMS going to be buried in the pack you can do a second set of wires or a connector to do your thing. If your BMS is accessible you might be able to use it's connection to unplug then charge /...

    reduce voltage drop between battery and controller

    This gives some info on doing a voltage drop test. You are measuring voltage between connections to see how bad the connection is, the higher the voltage (voltage drop) the more resistance at that connection - where your meter probes are. https://www.agcoauto.com/content/news/p2_articleid/331...

    High current Battery pack

    The off the shelf buss bars are not meant for current levels you're looking to get. Developing things people aren't doing at scale means developing parts to support what you're trying to do. Look at Tesla and Lucid battery assemblies for inspiration if you haven't. You can laser / waterjet cut...

    reduce voltage drop between battery and controller

    If you know where the controller measures the pack voltage on the pcb you could trick it for a short time by adding a capacitor into that circuit. But this piece of code is likely trying to limit motor current from seeing battery voltage sag too far so it doesn't damage a battery. If your...
