Re: Why the BMS Doesn't Work as You Believe

Ok I read the contents in the links you guys have provided. They pretty much support what I have been saying this whole time that the batteries balance themselves and charge them individually in multiple packs, or modules in their terms. Then you didn't understand what you read. The BMS in their te...

Re: Why the BMS Doesn't Work as You Believe

If you were to run a speed test by shooting a light from a flashlight (or laser beam) from one point to another, the electricity will will form much faster, connecting the two points side by side. So electrons travel faster than light. Wow. You really do have no idea what you are talking about. Her...

Ask Elon Must about it about the battery charging and why the BMS is not needed.
All Teslas have BMSes.
He is the guy who successfully designed (and engineered) his electric cars and how their batteries have shown to hold up.
Because they use BMSes.

Anyone can attend. Full conference is $1200. Exhibit floor only is $135 I believe.

RE+

Just got back from RE+ in Anaheim. Some takeaways: Seems like everyone now has a hybrid inverter plus MPPT charge controller, usually for a 48V battery. A few go to 400-800V batteries. Same thing with 48V LFP batteries. Every battery manufacturer had some sort of 1-5kwhr 48V rackmount or monolithic ...

Re: Is a motor controller essentially an inverter? Amp reading accuracy

So my question is, is a motor controller basically an inverter? Yes. However, the current reading you are seeing is likely not due to an "inverter peak" since most inverters are three phase and the three phases sum to a constant value. The Bluetooth meter is simply sampling in a narrower ...

And that's even if we don't finally take President Carter's advice and actually conserve energy for the sake of good stewardship. Right. There are two factors at play here. One is the slow but steady improvement of energy efficiency. We've gone from coal heat to oil heat to resistive heat to heat p...

Re: California’s giant new batteries kept the lights on in a heat wave

Let me help you here,…my “imaginable” estimate for a generation system using primarily Wind and Solar, would be somewhere north of 800 -1000 GWh If you go to all solar and wind (which no one has proposed) that's about right. The world output of lithium ion batteries right now is around 1000 gwhr/yr...

Re: California’s giant new batteries kept the lights on in a heat wave

I figure the math says that if there is not enough RE to meet demand at any point during the day, then if RE is used to recharge the Batteries, it just means more Gas generation is needed in place of that power, to meet grid demand. ! By that argument, since there's not enough gas generation to mee...

“Conserve energy now to protect public health and safety. Extreme heat is straining the state energy grid. Power interruptions may occur unless you take action.

Re: My ebike caught on fire.

I had two unit power pack batteries, one battery was 54v and the other 58v. I had these batteries wired in series making 112v. The battery that caught fire kept turning off, this also happened when the battery was not wired in series. I figured the BMS was turning the battery off. Charging the batt...

Re: EV charging stations = certain ebikes also can charge?

My charger will take 240V 2A, my question is what is the benefit of using a charging station? At that rate it's only worth it if you have no other option. However, I have one of those 3kW Huawei rectifiers that will push 3000 watts from 240 volts, and that _is_ useful. I also have a pot so I can di...

Yes, but they want $165
The connector itself is around $70 so you're not going to get any sort of complete adapter for under about $100.

Rather than to just blindly accept the theory that it is is all down to man made CO2 !
No one has claimed "it's all down to man made CO2." For example, a smaller percentage of the forcing is due to anthropogenic methane releases.
