Wibla posted:lifepo4 with the on-battery BMS hooked up to the computer in the car would solve this... but that's more expensive. There is one version of the Ioniq that does something like this. The 12v system is powered from a 12v pack made from the same cells as the main battery pack. But its seperated off in its own small compartment from the main pack. The dash has a button that can be held down to "jump" this smaller 12v pack from the main pack should it ever be dead for any reason.

Someone on Reddit stacked discounts and incentives (including low income ones) and got a "free" bolt ev lease. https://www.reddit.com/r/electricvehicles/comments/i2is9u/free_2020_bolt_lease_with_1k6k_money_in_pocket Their post is kind of a mess to read, but here's the body in case you don't want to click a Reddit link: quote:2020 LT bolt one pay lease 8350... 0r 10300 no money down ok credit. Dealer must discount bolt by 5k, watsonville has this price alreadly $13500 on the off MSRP . you can get others to do 4k to compete with watsonville making 1 pay lease $300 more. So for the math here how it works.

I did a little snooping around online to see how much the lithium-ion drop in replacement 12v batteries for a Tesla Model 3 cost, and I laughed the page closed when it was like $800. Maybe in a couple years when my OEM 12v will probably be reaching its limit there will be more affordable ones on the market.

There is no sane reason an EV should not just float charge the 12v off shore power when connected.

I think it's the EarthX ones or something similar that have a pretty smart onboard circuit that won't let them run down until they're dead, and other fancy features. I know there's someone in AI who's all about lithium batteries, but I don't remember who that was.

While I've switched to them in all my motorcycles and run them 4 seasons for weight reasons; they definitely can be killed. Yeah, lithium batteries should all have a protection circuit that permanently fuses off cells if one drops below the cells minimum voltage (2.5v typically) because if you attempt to charge them up again after they have depleted that far they usually explode because the metal plates inside the battery corrode and or form short circuits from the stresses at low voltage. Charging one up too high on the other hand (past 4.3v for most cells) and they can form lithium crystals which also can short out the cell and cause it to explode, only in this case runaway reactions are much more likely because the battery is also filled with energy in that state. Otherwise as long as they are kept within safe voltage tolerances (3.0v to 4.2v) they are basically impossible to kill, but will still degrade and lose capacity over time.

The Bolt (and others, buying charging modules from the same supplier?) will only charge the house battery from the traction battery and the traction battery is only connected to the rest of the car when it's switched on. There is no connection from the charging cable to the house battery. idgi.

Everyone needs a little solar panel on the rear spoiler like my leaf has. i think its like 9 W, so just a solar battery tender. I think probably put it on so they didn't have to care how much power they use while the car is communicating for the app data.

I don't know WHY it doesn't trickle charge/tend the 12v off shore power. Pretty sure our leaf does this when charging; when the HV battery is full the indicator lights switch over to flashing the 3rd light to indicate it's charging the 12V. However this may be just a coincidence and it charges it when it pleases like every other EV.

Way back when I bought my leaf the salesman told me the 12V got "topped up" every time it was plugged into shore power, in addition to charging from the traction battery and solar panel. He was a car salesman, though, so probably lying.

It all depends on how the power system is structured. Making something that can charge anything from any source without going through extra conversions costs money.

I don't know WHY it doesn't trickle charge/tend the 12v off shore power. Likely whoever engineered that particular part thought "well this is how it's always been done, why change?" This is also probably one of the reasons GM recommends unplugging the car and disconnecting the 12v battery if storing the car for more than a few months. If left plugged in for an extended period of time without being turned on, it will eventually drain the 12v. Supposedly the Bolt is the same way.

stevewm posted:Likely whoever engineered that particular part thought "well this is how it's always been done, why change?" I'd be willing to bet that it's to avoid having a lower-than-advertised charging rate for the traction battery, plus possibly having the converter for the traction battery not play nice with the downstream converter for the 12V loads, possibly leading to improper float voltages and whatnot. Plus just not needing to float the 12V on shore power under 99% of conditions.

Check out this cruiser: https://electrek.co/2020/08/04/evoke-6061-long-range-cruiser-electric-motorcycle-launched-15-min-dc-fast-charging/ It's pretty amazing if it can DCFC at the 125 kW they claim. Sucks that the AC charger's only 1.8 kW.

*points to rules regarding sources, points to electrek links, gesticulates wildly* Please find better/alternate sources in the future. Note: I'm not saying those articles are bad (except for that dumb space at the bottom for the editor to get their own ~~hot take~~ in,  gimmicky poo poo is that), but a release from the manufacturer or an english language german paper might be the better option. Less chance of mistakes or garbled translations.

stevewm posted:Likely whoever engineered that particular part thought "well this is how it's always been done, why change?" The Bolt is not that way. When the vehicle cord is plugged in The Hybrid/EV Powertrain control module (HPCM2) will check the 12V battery every 6 hours if the ignition is off. If the voltage is below a temperature dependent threshold ranging from 12.1 (cold) to 12.4 (warm)V, the Hybrid/EV Powertrain control module (HPCM2) will send the voltage set point to the engine control module (ECM). The engine control module (ECM) will send this to the 14V Power Module. Battery maintenance mode will charge the battery for 2-3 hours. If the Ignition is ON, the APM will cycle on as needed to maintain the 12V SOC. When the vehicle cord is not plugged in The Hybrid/EV Powertrain control module (HPCM2) will check the 12V battery every 4 days (2.5 to 3 days) and if the voltage is below a threshold of 12.0 may activate battery maintenance. If the high voltage battery state of charge is greater than 40% and the propulsion system is not active, Hybrid/EV Powertrain control module (HPCM2) will send the voltage set point to the engine control module (ECM). The engine control module (ECM) will send this to the 14V Power Module. Battery maintenance mode will charge the battery for 45-90 minutes..

I'm more interested in seeing the Rivians than the LiveWire in the Long Way Up. I think it's pretty interesting that Rivian built out a charging network before taking the trip, I guess it beats having a truck with a generator following them around. https://www.youtube.com/watch?v=ggu11EJo4L8

The 2021 Audi e-tron is up to 222 miles epa range (+18 miles) and the msrp is being reduced by quite a bit ($8,900), starting at $65,900 before incentives. The e-tron sportback will cost $3,000 more than the regular e-tron. I imagine this mostly comes from battery advancements - more energy dense, less expensive.

My jealousy for the SR/F and Energicas that came out after I bought my SR are only matched by the knowledge that both of those will be so severely outclassed in another few years when I’m upgrading.

Cadillac Lyriq unveiled tonight. I stole some details and pics from electrek's slide summary, pls no punish:  They want to offer rwd / awd options, 50/50 weight ratio, 19 kW (100 amp box) AC charging option, and a 300+ mile battery. They said they're 80% to production and it'll hit dealerships in the end of 2022. Cadillac said these will be available nationally across the US, they are not restricted to California. It will support up to 150 kW DCFC and feature super cruise. It also has a cool 33 inch screen.
