Well 14-50 outlet is most future proof. But assuming they run the appropriate sized wire, a hardwired wall charger can always be replaced with a 14-50 outlet easy enough.

Speaking of Regen.. The Volt (at least the Gen2) does this weird thing that if any of the tires slip even the tiniest bit, it immediately cuts regen out. It can be quite jarring when it occurs.

At the end of the road I live on, there is always a little bit of loose gravel from a nearby gravel driveway. When I am slowing down there and any of the tires slip it immediately feels like the entire car lurches forward until the brake pads grab on.

Does anyone use their EV as an office too? I do highway construction inspection and Covid has really pushed us to work out of our cars for doing paperwork instead of a field office. I’m having a hard time finding power consumption rates for “idling” with just the HVAC system running.

Well at least for my Gen 2 Volt... it depends on how hard the AC is running. The Volt has a variable speed compressor (as do most EVs I'd imagine), so it can speed and up slow down based on needed capacity. Going full tilt in MAX with fan speed maxed out it uses nearly 3kW according to the meter on the dash. As it approaches the temp set point the compressor and fans will slow down and the usage drops. I typically see it bounce between .5kW and 1kW at this stage. (the car rounds to the nearest 500watts and always shows a minimum of .5kW when turned on). I've left it on before for over an hour on a 85ish F day and it used just under 1kWh during that time period.

For the heater it is a different story.. That will use 7kW full tilt and the battery heater can use another 2kW on its own if its running.

I'd like more information on this because I know how tricky batteries are and it's hard to find actual information online to calm my nerves regarding them. So say your car is parked in a hot parking lot in the summer- will it start running an air conditioner or something to keep itself cool? A heater when the opposite is true and it's winter? How much juice does this take out of the battery while it's running and how long could a car sit on its own before it has to give up and allow the batteries to be damaged? How much power will it pull out of the wall to do the same?

This is quite a loaded question. It really depends on the particular EV.. Tesla's will cool the battery, even when unplugged, if they start to get really really hot but will eventually stop once the battery reaches a low enough SoC%. But it won't do anything if its unplugged and really cold. The Bolt EV will supposedly cool the battery in extreme hot temperatures even when unplugged under basically the same parameters.

Heat does damage, whereas cold doesn't. Hence why they follow this strategy.

Pretty much every EV on the market, and even some PHEVs with active management will maintain battery temperature when plugged in. I see this with my '17 Volt... It tries to prevent the battery from dipping below 48F or so and it will turn the battery heater on occasionally while plugged in. I can see it happen with my power usage meter. It amounts to maybe an additional $1 per month or so in the winter. It will also run the A/C when plugged in to chil the battery in the summer if needed.

Long term storage unplugged can be an issue, as it is with any car. For Volts anyways, GM recommends leaving it plugged in. Unless its going to be more than a couple months, then they recommend discharging to 50% and disconnecting the 12v battery to stop any vampire drain. Tesla's have a complete power down mode that shuts down everything for long term storage.

Really... don't worry about it.

Unless you have a Nissan Leaf. They famously don't have active cooling. And suffer badly because of it. Battery replacements are fairly common with them. They don't do well being fast charged a lot... or living in a hot climate for an extended period of time. This is not a trend seen with EVs that have active thermal management.

So basically going out and about for the day and leaving it in the elements isn't going to drain the battery. It may take a bit of a hit but it's a small hit compared to the energy used for just driving in general

Nope!

Also remember that a battery is a very dense object thus with a lot of thermal mass. It can take quite some time for them to heat up or cool down from external influence.

My home is heated by a heat pump with resistive backup heat. When the backup heat is engaged, it alone pulls 10kW. The only thing that blows up in this case is my electric bill.

Seriously though... Wouldn't TOU charging programs kinda fall apart once there are enough EVs? I mean if everyone is charging at night, then you are just creating another peak...
In my state (Indiana), TOU programs are not currently allowed. Regulations were only recently changed (in 2018) to allow electric companies to install smart meters. I would imagine TOU will follow the distribution of smart meters. (my home was switched to one just months ago).

This is the occasional reminder that I know of at least one FAA facility that spent thousands of dollars (more probably multiple tens of thousands) installing L2 EV chargers, and immediately locked the breakers open to make sure no one “stole” (that is a word actually used in an email chain on the subject by a manager) $3 worth of electricity from the government. This situation has now existed for multiple years with no resolution, since not only can they not figure out how to meter the power, they can’t figure out how to accept payment either.

They must not have consulted anyone, or done much if any research. There are companies out there with turnkey solutions to do just that. ChargePoint comes to mind.

A TOU rate would have to be REALLY cheap for me to bite on it.

As it stands my power averages between 9 and 11 cents per kWh depending on usage for the month. They use a scale based on consumption. The first 400kWh is billed at one rate, then next 400kWh at a slightly cheaper rate, and so on. With a poo poo ton of "riders" on top of it. If it wasn't for the riders and "delivery" charges it would probably be like 4-6 cents per kWh.

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.

Depends on the car. Volt does not charge unless the vehicle is on, and it charges the 12v off the traction battery. 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.

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..

My Bolt is still in OnStar demo mode...I leased it in January.

For awhile GM was giving 5 free years of "Basic" OnStar to Volts and Bolts upon purchase/lease. And it was transferable to new owners if you sold/traded in within the 5 year period.

My 2017 Volt was one of those. I have "Basic Connectivity" until December 25, 2021. I get the remote keyfob, charging status, and car locator (which the basic plan is not supposed to have) for free. They don't have anything else on offer that I would ever think about paying for.

They did not, they give you 5 years of remote connectivity. They changed what they give you afaik. I had to call onstar for it.

Yeah they have changed it multiple times :/

For some time 2018 Volt owners where being told it was not included, only a 3 month trial was... then it suddenly was. For several months the location feature was disabled, then they turned it back on.

Worst of all only 1 out of 4 people you called at OnStar knew what the hell you where talking about.

I had to go through this with mine. When my free trial of the "premium" package ran out, it completely quit working. I had to talk to a couple different people to get the Basic service I was supposed to have turned back on. Then in early 2019 it stopped working again. I had to call and have it re-enabled.

When we moved into our new corp. office about a year later, I made the discovery that the one radio I didn't sell was still active! That was 11 years ago; to this day we still have free XM radio as our background music. I'm guessing XM/Sirius only sends the de-activation signal for a period of time. Since the radio was off and unplugged for a year, it never received that signal.

So I've floating the idea about getting a Bolt, possibly. Maybe... I've seen some cheap off-lease ones come up around the area.

The dealer I bought my Volt from claimed to have a few Bolts on the lot. 3 new ones and 2 used ones. The new 2020 ones where 27k-28k They had a bunch of pictures of each one online, the under hood pictures showed they all had DCFC. (DCFC models have a large high voltage connector with 2 wires sticking out of the front of the power distribution box)

I decided to run up there and take a look.. When I arrived I discovered ALL of the new ones where NOT equipped with DCFC. :doh: Looking further, it appears the under-hood picture was identical on all of them.

so I can leave it in Sport mode and not give a poo poo because all the energy it uses will be free.

All sport mode does is remap the throttle to be less linear, being heavier at the bottom end. Surprisingly it doesn't really make much of a difference on total energy usage over a charge. Unless you are doing a tire squealing jack-rabbit start on every take off.

Here are some common things that I see new Volt owners get tripped up on. Some tips and tricks..

The EVSE that comes with the car is a 240v capable device with a 120v plug on it. You can make a simple adapter with bits from any hardware store to plug it into your 240v outlet of choice cutting charge times in half. Assuming you have a 240v outlet available. Its still limited to 12A on 240v (2.88kW), but it means a full charge in 5 hours instead of 10.5 on 120v/12A. 240v charging is a few more % efficient plug to battery as well. The 2017 has a 3.6kW (240v/16A) onboard charger, so if you get a EVSE capable of delivering at least this, charge times from a empty battery are just over 4 hours.

ERDTT: "Engine Running Due To Temperature". By default the car is set to start and idle the gas engine when the temperature drops below 34 F. For 2017 models that can be changed to happen at 14 F instead (the "Deferred" setting). But it cannot be disabled.

Engine Maintenance mode: If the gas engine has not started in ~6 weeks, the car will start and idle the engine for approx 10-15 minutes. It lets you defer this once.

Fuel Maintenance Mode: The car keeps track of the average age of gas in the tank. As it approaches 1 year in age, it will force you to use it. You cannot defer this. Adding gas to the tank decreases the average age.

Oil Life counter: The oil life counter goes by both time and how many hours the engine has run. If you basically never use the gas engine it will slowly drop down to 0 over a 2 year period.

The 12v battery is a AGM type. The car is designed to accept and charge ONLY a AGM battery. If you ever have to replace it do not put a standard flooded cell lead acid in it!

The EV range meter, or GOM/"Guess-O-Meter" as it is called, is based entirely on the driving efficiency of your last full charge. So depending on your driving style, weather, climate settings, etc.. it can vary a lot. Don't be alarmed! (many new Volt owners are!)

Most of the EV part of the drive train including the battery is covered under a supplemental warranty called the "Voltec" warranty. This lasts for 100k miles or 8 years. Or 150k miles/10 years if the car was originally sold and currently registered in a "CARB" state.

All 2017 Volts where sold with 5 free years of "OnStar Basic". This IS transferable to new owners. A 2017 Volt will still have some of this left. You can call OnStar to have it activated and transferred to your name. You may have to make a few attempts at this as OnStar reps are not always the smartest bunch. It helps if you call OnStar FROM the car by pushing the blue button. OnStar Basic gives you app access to see charging stats, tire pressures, GPS location, remote keyfob, etc..

Edit: Forgot about VoltStats! Once you get OnStar enabled, you can link your car to the VoltStats website. It polls OnStar once a day to get various stats about your energy efficiency and usage. Here is my VoltStats page: https://www.voltstats.net/Stats/Details/8980

When I bought my Volt I told the guy before we even sat down that if there where any upsells, tacked on bullshit like warranties, paint protection, etc.. I walk. It appeared to have worked, they didn't even ask. I did have to sign the paper turning down the warranty, but they didn't ask about it. The "sales guy" had no idea what the car was, why it had a plug, etc... Just your typical dealers don't know PHEVs/EVs bullshit. (This same dealer currently has a lot full of 2020 Bolts ordered without DCFC, lol) They did get kinda pissy when I introduced some stacking discounts I had at the last moment and they had to cut another 1k off the price. The finance guy said "Wouldn't you just rather have a Malibu instead?" I like to feel I won against a dealership that day...

Quite the different experience to when I bought my previous vehicle... They had tacked on about 3k in add-on junk and were not taking no for an answer until I stood up and walked out of the office. They removed it then, though in hindsight I shoulda just kept going just as a gently caress you to them. Assholes.....

Wow... glad I live in an area where power is cheap! My household averages 30-50kWh a day in summer and 50-80 in the winter. But the most expensive I have ever seen my electric is 11.5 cents per kWh, and that is with all the riders and fees they tack on included.

Indiana regulatory rules do not allow for time of use power rates far as I know. (though they are coming, utilities got permission to install smart meters in late 2018) It is currently a tiered system based on usage. i.e. the first 500kWh are at one price, the next 400kWh after that are slightly cheaper, and so on.

It generally costs a whole $1.10 to fully charge my Volt. But given my daily commute is only 15 miles roundtrip... It is more like 39 cents.

This seems like it can be a mix of DCFC, level 2, sales resources, etc. I think this is similar to requirements for Chevy dealerships that sell Bolts, though that's voluntary, per-dealership.

At least for Bolts/Volts it seems the dealers only need to have at least one Level 2 charger and a trained tech. Because any GM dealer around here that services and sells Bolts or Volts, that is all they appear to have over any other GM dealer.

Though some GM dealers carrying Bolts do have "Level 3 Lite" chargers that are 25kW CCS units.

An EVSE with a 14-30 plug would be limited to 24A. (continuous loads are limited to 80% of the circuit rating). 14-50 EVSEs are going to be limited to 40A. (which is why 7.2kW plugin EVSEs always have a 6-50 or 14-50 plug on them)

Any electrician might refuse to add a circuit to an ancient fuse box... In addition, your own locality might require it to be replaced with a modern sub panel with circuit breakers. Many have rules saying that old infrastructure cannot be added to or modified. Only used as is. You would have to consult with a electrician familiar with your area.

You can get relatively cheap old rolls royces, I'm guessing due to the combination of expensive maintenance and that the target market only wants the latest models. I wonder if EV conversions could make it reasonable to keep them going.

I would think some of them would be a nightmare.. Older British luxury vehicles tend to have a lot of motor driven hydraulic systems, which is the cause of some of those expensive repairs. Like suspension, brakes (not always a traditional assisted brake setup), windows (some Rolls have hydraulic windows!), etc. It could be challenging to get all that working in a conversion scenario.

To be fair, GM didn't advertise the capability at all. Clipper Creek made them, and GM just sold them as portable 120v EVSEs. I'm not sure who figured it out, but a couple people took them apart and found out that yeah they're well-built and designed for 120 or 240. There were a couple of years of testimonials online before I made my adapter and tried it out (after verifying part numbers).

From what I can tell, it originated on the GM Volt forums.

Some models of the EVSE included with the Gen 1 Volt where also dual voltage, but not auto switching. You have to change a jumper inside the unit.

It was quickly discovered the Gen 2 unit was dual voltage out of the box; the PCB is actually labeled for it. This was further confirmed when the Euro version of the Bolt shipped with the same exact EVSE with just a different plug on it.
