I try. If its not much more, if they have it, and its not more hassle than it should be.
Lets start by saying the people at the local KIA dealership should really know their products better. My wife just signed a 3 years lease on a new Kia Niro full EV. (Don't lecture me. She chose that.) If anything her time is more valuable than mine, so driving out of her way to use an EV charging station and having to sit around waiting is just plain stupid. It made no sense to me, and the eyes of the smartest people at the local Kia dealer just glazed over like they couldn't imagine not using the free (500 KW included free) charging stations at their dealership, their sister Hyundai dealership, or one of the local public charging stations.
When I started asking questions I already knew decent name brand chargers were available from old names like Schumacher. The dealer folks kept going on about how slow it would be to use a cord, and we should have a Kia "Level II" charger professionally installed. I hadn't really looked at price, and their price wasn't outrageous as dealerships go. They just couldn't answer my questions about what is level I, level II, and why a hardwired level II was better than a corded level II. They suffered from clue deficiency. They didn't even seem to have a definition of what level II was other than its a bigger number than level I.
I gave up and went home where I took a quick look on the Schumacher website where with the most casual of study I quickly figured it out.
Many of the plug in cord type charges are both Level I and Level II with the only difference being input voltage. You can plug it into a 20 amp
240V outlet and charge at 16 amps. With an adapter you can plug into 120V outlet and charge at 16 amps. 240V is Level II. 120V input is Level I. If there is anybody in this group who doesn't already know what that means: Total power is watts. Watts is amps times volts. Then I looked a the wall mounted chargers and discovered that they were somewhat configurable. For example the SEV1600HW (HW stands for hard wired) can be configured with a plug upto a 50 amp range type on a 50 amp breaker. It can also be hard wired directly to larger breakers and set for higher charging current.I opted for a new 50 amp breaker on the sub panel in the garage and a 50 amp range plug. The recommended switch settings are to charge at 40 amps in this configuration. Its not as fast as it could be, but we already did a test with a Schumacher cord charger last weekend with it plugged into the 120V ceiling receptacle next to the garage door opener. It was enough after one week of normal daily use back up to 100% charge. I am sure 40 amps at 240 input will be plenty enough faster than 16 amps at 120V that she won't complain.
The big bonus, is that now I have an outlet in the garage where I can plug in a welder. That's the main reason I went with a 50 amp breaker/outlet instead of hard wiring into a 70amp breaker instead. I no longer have to drag things through the field to the back of the shop or string extension cords (I have some heavy 240V extension cords) all the way through the shop to work out in the driveway.
I don't think the Schumacher is much different (other than price) from the Kia charger and I would have paid the Kia premium, but they just couldn't answer any of my questions. If I pay dealer premium price I expect the dealer to know their products.
... Oh I'm not done yet. I decided to just buy all the electrical stuff locally at the big box store, so it would be here when I was ready to hang the bigger wall mounted charger and set it up. Whichever one showed everything in stock. Home Depot showed everything in stock on-line, but alas they didn't actually have the 4 pin 50 amp plugs their website said they did. Then I grabbed the wrong breaker... and it all just annoyed me. I checked Lowes and they didn't show any 50 amp (range plugs) on their website as in stock locally. I ordered one on Amazon, and it should arrive today. I wound up getting the correct breaker over at Lowes, and on my way to the check out I happened to see on a bottom shelf a box over flowing with 50 amp 4pin plug cords in just the right length for the job.
In the end I would have been better off just buying everything from Amazon. I'd have had the job done two days ago. Next time somebody lectures me about buying locally I won't punch them in the mouth, but I'll probably think about it. Oh, yeah, I had plenty of 8awg wire on hand already. More than I will probably ever use.
As to the lease / EV. Well I'm not ready for EV for a whole host of reasons. The big one being that often when an EV battery bricks the car it costs more to replace than the car is worth, and EV batteries don't seem to last as long as a gas engine at this point. My wife has had an illogical desire to buy an EV for a while now. I argued. I pointed out the less than ideal logistics. I detailed the longevity issues. I even pointed out that a paid off gasser would cost less to operate (no payments) than a new EV. She wasn't having any of that. She didn't disagree with me. She just wanted an electric car. Generally I am against vehicle leases as well. About the only one its better for is your accountant if its a business vehicle. Otherwise you are just paying rent and gaining no equity. In this case though I think its the right thing to do. In three years battery technology will have improved, and three years is well within the average life of an EV battery at this time. She won't be stuck with a large paper weight when it bricks the car. It will be somebody else's problem.
FYI: The Kia Level II wall charger was $750 plus installation. The Schumacher on Amazon was $550 with free shipping. I spent less than $100 on breaker, box, connectors, outlet, and misc, and I had wire and smurf on hand.
