You misunderstood, the fast charge is the least conducive of prolonging battery life. Slow charging promotes long battery life. Hence the 7.2 and 3.6 kwh chargers on board, which is what you should use 95+% of the time.

Go read up on Leafs with short battery life in hot climates like AZ, in the heat, which is damaging. Charging fast generates heat in the battery, which is damaging to the battery and reduces it's useful life. This has always been the dilemma of recharging quickly.

Wait, and get anything you want with the 7.2kwh charger on board. VW suggests using the DCFC unit "sparingly" with no back to back DCFC recharges, it's in the owners manual. You really need a 240v 50amp outlet that will handle a 40 amp EVSE, if you want to do things right. A 30 amp welder outlet is only good for 24 amps, it is derated to 80% for continuous load like when recharging an electric car.

Unless where you work supplies an EVSE for you in the workplace parking lot, mooching electrons for free is a tough way to go. Better to provide your own source of recharging, on both ends, or pay to recharge somewhere near work. I don't feel with bad weather, a 50 mile commute each way is going to work out for you, unless you enjoy being tethered and waiting for a recharge... the base entry SE is probably not your best option, IMHO, not with 50 miles each way. That's two recharges per day.

It's a killer deal alright, so good a deal they can't give it away. There's your sign.[/quote]

Thanks for the input! I needed confirmation of my concerns. Dealer was assuring me I would be okay with the 3.6 KWH charger even if I only had 4 hours are work. I wasn't sure they were accurate from my research and then found this thread.

My welder outlet is actually 240V 60 amps; two connecting 30 amp breakers. I thought they were only 20 amps each. So, home charging would be a level 2 40 AMP EVSE. I will throw my meter on it to double check output. I am in a federal building with no parking so charging at work will have to be on a public charger, it's a Green Charge/ChargePoint+ station. I guess I will wait. I am sure when the longer range 2017's come out I can get an even better deal on a 2016 with the 7.2 KWH onboard.

If the ChargePoint+ has the SAE combo plug will that always give you a fast charge or can you just go normal charge? Since the fast charge is the best to prolong battery life.

Also, will the SAE combo plug even connect to a non DCFC e-Golf charge port?[/quote]

you have two 30 amp breakers at 120. 120 +120 at 30 amps is 240V at 30 amps, not 60 amps.

I wrote that wrong for sure, good catch. I was trying to ask about the public stations with the Combo SAE chargers, I know you want to avoid fast charging unless you really need it. So, with the SAE Combo chargers that ChargePoint+ offers, do you have to fast charge if you hook up to them? Or, can you choose to just charge through the SAE J1772 port only?

You hook up to a level 2 charger with a J1772 handle to charge at level 2, you hook up to a SAE combo plug to a DCFC port on your car to charge at level 3. No, a level 3 charger will not charge at level 2 rates. Level 2 rates are ac voltage passed through the on board charger in the car, which converts to DC voltage to recharge your battery.

Dang, that is what I was afraid of. No way to avoid fast charging on the public SAE combo chargers available to me in Norfolk. Thanks again. I am sure there are others who will benefit from all this chatter.

it's pretty hard to find level 3 chargers without some level 2 chargers near by, also. Adjust your search parameters to "J-1772" on your EVSE charging apps to find more options.

Just a refresher, since VW e-Golfs with 35.8 kWh batteries are either already here or coming soon, to a dealership near you. If you get a 2017 or later model e-Golf, add in a factor of 1.5x the charging times shown for 2015 and 2016 e-Golfs equipped with the 7.2kwh charger version on board.

I think the OP already included that in their calcs.
