2035

Research into graphene batteries looks hopeful. There are other battery chemistry research going on. Something that has a less impact on the enviroment is needed.

If you are doing "What ifs" then in a blackout electric pumps at local gas stations are also off, so unless your ICE "has a full charge" you are also stuck

 

[sgtsandman]

I don't think it's possible. The impact just gets moved somewhere else. There is no free lunch. We are seeing that with the used solar panels and wind turbine blades. Never mind batteries.

In our current supply system, if the power goes out long term, everyone is S.O.L. regardless of what powers their vehicle.

Unless you have Solar power stored, not sure any one(even Calif.) has figured out a way to block the Sun
Much like having stored liquid fuel, but its replaced daily and doesn't "go bad", so quite different in long term use

But if you have firewood you could try wood gas system for ICE

Mama Gump... searching for a working lottery machine post power grid failure.

Solar will get you there longer but the panels and batteries eventually fail. Fuel will definitely go bad after about a year. Movies like the Mad Max series are just pure fantasy. Unless you have a way to make more fuel, ICE is toast. Then we'll be back to walking or riding a horse or donkey.

I get all my news from the headlines in the tabloids in grocery check out line, I don't actually buy them and read the articles, I am not an idiot, duh
Headlines are enough

Elvis was spotted driving an EV, good enough for me, I am switching to EV(Elvis's vehicle)
Facts are facts

If you have seen Men In Black. Those grocery checkout tabloids are the only real true source of news.

The power grid across the nation is antiquated and needs upgrading and/or replacement. All for similar reasons in California. Sooner or later the customer base is going to say they have had enough and do something to the power companies for not meeting the demand. Especially if they only have until 2035 to get the grid ready for when all those EVs are going to be on the grid.

It might be time for people to start figuring out how they are going to get power to their house independent of the grid. Whatever is likely to be more viable, wind, solar, hydroelectric. Which ever system or systems make more sense for where they live.

The roads and highways are pretty beat up too. I feel bad for the truckers, those right two lanes are more potholes than not.

Clarification - I was just asking if the heat was still a concern when doing the typical daily charging at night/at home since that would be done on a slower charger that would also be throttled down since you're only adding a few percent anyway. Why is that harmful?

I can give a personal example. My buddy went on a trip and left his Tesla parked at my house for a week in july. I have a solar trailer that doesnt like the heat as well. The Tesla charged a little bit slower in the heat, but I didn't really notice. The solar trailer however, the inverters would shut down mid day, I would have to fire them back up when it cooled down in the evening. I'm gonna build some shade over the batteries and panels, maybe add fans. I think the Tesla throttles itself down.

I forgot to add you also manually adjust the charging amps anywhere from 6 to 32. I was charging around 8-14 most of the time.

I'm not sure how to rephrase my question, but that's really not what I was asking.

I forgot to add, yes its harmful...Not detrimentally, but the same way heat affect engines. They don't like too much of it. Batteries and also inverters don't like excessive heat (or cold).

By harmful I mean it shortens battery life and capacity over time.

 

[fastpakr]

I get that.

My question is about the idea of low level daily charges specifically. Ron referred to that being harmful, and I was looking for clarification on that. There are definitely some implications to keeping the battery at 100% or full discharge, and to charging too rapidly. What I'm not clear on is the problem with adding back small amounts like 10-20% at low rates during at home overnight charging when there should be minimal heat created in the process.

Kinda like how laptop batteries that live on the chargers don't work so well when they leave the charger compared to like a cell phone battery that gets exercised regularly.

They need to cycle from full to empty and back to full. Just going full to almost full back to full hurts the battery long term.

Interesting, I would think the contrary, fast charging is harmful. I know its good for batteries to cycle, but not fully drain. My power tool batteries seem to have built in protection for overcharging, over draining, or overheating.

Although I would say low level daily charges wouldn't let the battery cycle enough to stay healthy and hold a full charge. Mostly draining and then fully charging the battery helps them not lose charge capacity over time. Although they say not to charge the chevy bolt past 80%.

I do have a 6.0 Milwaukee 12V battery that lets itself get overdrained, and my rapid charger won't accept it. I gotta use the regular charger and reinsert the battery a few times to trick the charger into feeding it enough before the lights blink bad to let battery start accepting a charge.

Hope that helps.
