I am pleased to see that batteries have an 8 year/100,000 mile warranty.

But... Battery etiquette... I am always confused about leaving my iPhone connected to the charging cable all day, or in this day and age whether we need deep cycle the battery before charging again, etc...

I don't want to have to worry about that with a $85k EV.

As an EV newbie.... What do you think we can expect in terms of intelligence of the e-tron battery recharging system.

Is it OK to plug in every day/night, and leave plugged in? The charger will cycle on/off so that we aren't abnormally shortening the battery life by leaving it plugged in?

For instance... Here's a blogger's post that has me concerned about charging all night, not charging to 100% etc. Many of these would be exactly what I don't want to be worried about.

"Getting the most out of your EV battery doesn’t just help you travel farther, but it helps make sure you don’t find yourself stranded on the side of a road or embarrassed because you must find reliable EV transport during a road trip because you didn’t plan for battery charging and your battery runs out of juice to go any further.
Some EV batteries have higher drive time than others and it is essential that you take time to learn as much as possible about your specific battery and the car you own so you’ll know how often to charge for best driving performance.

When you use the right maintenance schedule, an EV battery can last for several years or longer. Here are ten sure fire ways to help extend the life of your EV battery and help prevent breaking down or having to buy a new battery sooner then you want to.

1. Watch Your SpeedWhen the flow of traffic allows, try to drive slower as this will help conserve energy used from your battery. It isn’t always possible to drive slower, especially when traffic is going fast on the interstate, but choosing to take a road less travelled that may have a slower speed limit could be a smart alternative to driving fast and then having to spend hours recharging because you ran the battery down too fast.
2. Stop Charging to the MaximumWhether it is force of habit or you just believe getting a full charge will allow longer commute time, with lithium batteries, it is best to charge to around 80% rather than getting a full charge. Not charging fully allows space for regenerative braking that can convert kinetic energy into usable energy if there is enough space in the battery.
3. Plan for Vacation StorageIf you have plans to fly to the beach this spring and your car will be sitting in an airport parking lot, be sure to have it charged enough to sit at the airport and then get you home when you return. If you’ll be taking a cab from your house, leave your car plugged in but set the charge at around 50% so it won’t overcharge while you’re away. Remember that the battery charge will go down a little as each day passes, so make sure you have enough charge to last until you return and can get home to charge again.
4. Park in the ShadeMany people will park a mile away from a store just to avoid parking in the hot sun. When it comes to parking spots for your EV, try to find a shady place to pull over while you go inside. This is not only going to help keep the car cooler inside but will also help prevent the thermal management system under the hood from running the entire time or your battery overheating while you’re away and draining your battery charge.
5. Take Time to Charge in the HeatWhen it’s hot and muggy outside, you need to take more time to put your battery on charge. Lithium batteries don’t like the heat any more than you like it, and they tend to drain more when it’s hot outside.
6. Search Your Route Ahead of TimeNo matter where you’re going, you need to search ahead of time to see where the available charging stations along the way are located. Have a backup plan to be able to charge if the location you choose is already full or out of service. It’s not a good situation to find you need a charge quickly and have no idea where an EV charging station is located. To locate charging stations nationwide, you can check the website PlugShare to find one along your driving route.https://www.clippercreek.com/tax-credits-2017-extended/
7. Stop Quick ChargingUsing quick charge to charge your EV battery seems like a great way to get a charge fast so you can drive, and yes you can charge faster when you put the battery on quick charge, but every time you use quick charge, it takes a little life away from the battery. Let’s put this into perspective. If you charge with a normal charge for eight years, your battery might show at least 80% left in it. Charging with a quick charge for all those years can decrease your battery life down to 70% or lower in the same amount of time. While it may not seem like a major difference, it is the difference between a battery lasting for a few more years or finding yourself in need of spending money to buy a new battery sooner than you planned.
8. Avoid Deep DischargingIf you let your EV battery discharge completely before recharging, it can take time off the overall life. If you see your battery dipping down near the 30% mark, you need to charge it, so it won’t get any lower or won’t stay low for a long period of time.
9. Time Your ChargeMany people tend to plug their EV battery in at night, so it can charge while they sleep. This is an ideal time to charge, but you need to watch the time it charges so it isn’t on the charger for too long. If you don’t already know, lithium batteries are most stable when they are holding at around a 50% charge, but this is not usually enough charge to keep your car going if you need it to during your busy day. Since this is not always a good option, you need to make sure your charge time is not too long and that you don’t unplug the battery and take off for a drive immediately. If your charger has a timer, set it to shut off at least an hour or two before you plan to leave your house in the morning. This way, the battery is charged and is not hot for the drive.
10. Mountain ModeIf you own a hybrid and plan to drive on a route that includes hilly or steep terrain, switch the car over to Mountain Mode so it will use the power from the gasoline and will conserve the battery power during the drive. Mountain Mode should be switched on at least 25 minutes before you reach the steep terrain, so your battery doesn’t go into a deep discharge as you are driving uphill.

While many of the newer EV’s can be plugged in to charge anytime and many companies have now added built in measures to help ensure batteries cannot be overcharged or will overheat, these tips are still important and can help you wrangle at least a few more drives out of the life of your EV battery. Be sure to check with the dealership as well as inside your automobile manual for recommendations on keeping your battery charged and helping ensure it has a long life.

And... Anyone know if this battery will be replaceable?

Does anyone know if this e-tron is designed to accept the 350 kW charging option in the future or is there some limitation in the engineering that limits it to 150 kW? I've yet to see anything definitive in the press information that addresses this.

cgiard

The 350kW charging is based on 800V, and the e-Tron battery is 400V, so it wouldn't be able to go at that speed. It could (in theory) go at 175kW, if the electronics can be made to support it.

rpreuss

The car will control the rate of charge and will limit it to 150kw or less even if connected to a 350kW source.

fideba

Yes, I've seen interior videos which clearly showed a slider to specify to which percent you want to charge

I've had a tour of the actual factory where they assemble the car and battery (one of the many advantages of living in Belgium :-), and asked that very question. I got a kind of evasive answer: while it's clear that the battery pack is designed to be able to removed, it certainly wasn't something they are planning to do (often)
