Been a reader for a while (hate the term lurker...such a creepy description), and have *really* appreciated (most) of the posts, wisdom and experiences others have shared, and figured it was time I contribute something.

First some background:
- Live in the US and purchased a 2019 Kona Electric Limited in April 2019; build date is December 22, 2018.
- This is my first (all) electric vehicle; had a 2007 Civic Hybrid, but in my opinion that doesn't count.
- This is my second Hyundai; had 2013 Elantra GT manual.

Equipment owned related to the Kona:
- Juicebox Pro 40 (with Wifi) connected to a 50 amp circuit to charge the Kona at home, but occasionally will DC fast charge at EA, ChargePoint, EVGo, SemaConnect, etc.
- Tesla to J1772 converter cable for charging at Tesla Destination (AC/level-2) charging locations if ever I'm in a situation where this is the only available option.
- EGO inverter with two (2) 7.5 amp and two (2) 5.0 amp batteries.
- SeaSucker Monkey Bars for carrying around Kayaks since my Kona does not have the ability to add rails without drilling into the roof.
- Saris Bones 3-bike bike rack.
- 3DMaxpider all-weather floor mats.

Possible future purchase:
- Battery powered electric blanket (Amazon has one for $250) so I don't have to run the heat as much during the winter to preserve battery power on longer trips.

Equipment I do *not* own:
- ODB2
- TorquePro App

My experiences:
- Using the Hyundai supplied granny charger, the EGO, with the batteries I own, adds 4-miles of range after draining the EGO batteries completely in 47-minutes.
- I've used the Tesla to J1772 converter cable twice to validate that it works...it does.
- Kayaks are on order, so the SeaSuckers Monkey Bars haven't been used to carry anything, but I have mounted the Monkey Bars and driven around at 70+ MPH (112+ KPH) without issue, other then you can definitely hear wind noise. In addition to ordering Kayaks, I have the Thule Compass on order as well. I expect my first test of the Monkey Bars with the Kayaks and Thule Compass will be a slow trip around my neighborhood roads until I gain confidence that the suction works as expected/desired.
- The Saris bike rack was purchased the same day as the Kona (i.e. well before purchasing the Monkey Bars). I have both a Trek Farley fat bike and a Motobecane road bike (complete opposite bikes). The Saris caries both bikes without issue and it hasn't dented the Kona's hatch or damaged the roof spoiler.
- The best description of (obnoxious) motor noise I've heard on this forum is playing cards in the spoke of a bike's wheels. I think my Kona makes this noise, but I'm also at an age where certain frequencies are not as noticeable to me as they would have been 20+ years ago, so I haven't pursued this with the dealer.
- There is much (entertaining) debate on this forum about regularly charging to 80% vs 100%. I have taken Apple's lead and what they've done with my old iPhone to preserve battery life/health, and only charge to 80% unless I'm going on a longer trip where a full charge is needed. But do keep the debate going - it is interesting, though don't expect me to join in.
- I set my regen level to zero (0); I like using the paddles to stop as it gives me, in a very small way, a more connected experience with the Kona like I had with my Elantra GT manual.

Recent experiences:
- In May (2020) I had the first BMS update applied; no issues, but I really appreciate the feature enhancement where the brake lights stay on after holding in the left paddle until the vehicle stops and it remains lite after releasing the paddle after stop.

- Yesterday (20201109) the second BMS (196) was applied; again no issues. However, though I typically only charge to 80%, last night I charged from 24% to 90% to see what would happen. Notable changes are as follows:
--> Previous to the 196 update, the Kona (on it's internal display) reported between 7.6 and 7.8kWh charging rate using the JuiceBox Pro 40; this was consistent all the way to 60%, 70%, 80%, 90% and 100%.
--> After the 196 update, charging was steady at 8.0kWh until 80%. Once it reached 80%, for approximately 10-minutes, it throttled down to 1.0kWh; it never went to zero (0) or stopped charging (the JuiceBox reported the same 1.0kWh charging rate). After 10-minutes, charging returned to 8.0kWh until it reached 90%; this was expected since the Kona was set to stop charging at 90%.

One more thing on the 196 update, I was told it would take about 45-minutes to apply the update. The time was pretty much spot on, though I thought it should've take 2-minutes at most; go get the fire extinguish, hand the fire extinguisher to the customer, Kona Electric patched. ;)

Thing I would like to do if I had the nerve and step-by-step instructions:
Hobbit wrote a while back about implementing a switch that notified tailgaters (by quickly illuminating all rear lights) that they are dangerously close. Sadly, I consider myself a hardware guy (in the IT world), but something about rewiring my vehicle intimidates the hell out of me.

Finally, as stated at the start of this post, I really appreciate what's been shared here over the past year+, and as they say in the Reddit world, "AMA."

Belated welcome to the forum! Good feedback on the bike rack, that's the kind of info someone searching around deciding what car to get might be looking for.

The best description of (obnoxious) motor noise I've heard on this forum is playing cards in the spoke of a bike's wheels. I think my Kona makes this noise, but I'm also at an age where certain frequencies are not as noticeable to me as they would have been 20+ years ago, so I haven't pursued this with the dealer.

You might want to get someone to help you with this, give you a second set of ears. Maybe have them listen as you drive past (or have them drive past you). Clicking noises from the drivetrain have been linked to some rather serious mechanical repairs, so you'll want to investigate more closely.


After the 196 update, charging was steady at 8.0kWh until 80%. Once it reached 80%, for approximately 10-minutes, it throttled down to 1.0kWh; it never went to zero (0) or stopped charging (the JuiceBox reported the same 1.0kWh charging rate). After 10-minutes, charging returned to 8.0kWh until it reached 90%; this was expected since the Kona was set to stop charging at 90%.

This matches the experience of several others so far, as well as a description of the update from a tech. It's believed the BMS is doing some testing to make sure the battery is in good health. Since it continued/completing the charge cycle, yours should be in decent shape!
 
You could almost dope out how to wire in the "tailgater switch" by examining the big-picture
in my page, http://techno-fandom.org/~hobbit/cars/ev/141yb-build.jpg ... the connector is
near your left knee when driving, and there's one other stray one at a different spot for the
reverse lights. I could do an addendum with the specifics, I suppose, but 1> the assumption
is that someone has the schematics, and 2> Hyundai doesn't make capricious changes to
the harness in different production runs.

Interested in the Tesla to J1772 adapter.. which one did you buy?

I didn't think Tesla lets anyone other than their cars use their chargers. Can you just pull up to a tesla supercharger and plug that in?

It's for Tesla destination chargers only, which are at places like hotels and restaurants. They're pretty much just Level 2 EVSEs with a different plug. It also works for other Tesla-plug Level 2 chargers, like the travel charger and the High-Powered Wall Connector.
It definitely will not work on a Supercharger.
 
Thanks, Electriceddy (and TRSmith), for responding to doggyworld.

I've seen much confusion on this forum (and other EV forums) about the differences between AC vs DC, slow charge vs fast charge, Tesla Destination charge vs Tesla Supercharge, and level-2 charging vs level-3 charging (not to mention level-1 charging). My post attempted to be clear about what (and where) this adapter is used for by including "Destination (AC/level-2)," but even with this detail, there is still much misunderstanding of the different terminologies in the EV charging world.

The only thing I'll add to this is that on my first test of the adapter I went to a mall (well before the pandemic) where there were five (5) Tesla Destination/AC/Level-2 charges and one (1) J1772/AC/Level-2 charger. Strangely, all five (5) of the Tesla Destination chargers were open, but there was a Tesla Model 3 using the lone J1772; all were cost free for mall patrons. After an hour of walking through the mall, the adapter worked without issue; that particular Tesla Destination/AC/Level-2 charger provided a charge rate of 6.5kWh with the adapter. Also, the Model 3 was gone when I came back and I'd to think this caused the owner of the Tesla to scratch their head. Truth be told, the Model 3 owner could have chosen the J1772 to charge their vehicle because all five (5) of the Destination charges were being used when they arrived, but all had left by the time I arrived (i.e. not trying to lay blame on the Model 3 owner for using a charger (i.e. J1772) that typically non-Tesla owners can only use). But this experience left me feeling better about shelling out $250 (US) for the adapter.

Thanks, Genevamech, for the welcome post to this forum. Appreciate the suggestion on getting someone with more youthful hearing to assist and (possibly) bringing this to the attention of my dealer. As an add on to my original post about the BMS 196 update, I took a long ride to Delaware yesterday which brought the percentage of battery charge down to just above 10%. However, this time when I charged to 80% the rate was 7.6kWh (all the way through), which was a typical rate prior to the 196 update, instead of the 8.0kWh achieved immediately after the 196 update. The temperature, however, for yesterday's charge was about 15 degrees (Fahrenheit) cooler than it was when charged immediately after the 196 update, so this could account for the slower rate. Either way, I'm not worried/concerned, but an interesting difference I'll continue to monitor.

Finally, thanks, Hobbit, for providing a fuse box diagram; completely understand your disclaimers on schematics and production runs.
 
Tangential to PuffDaddy, but it reminded me: Apparently the latest version of Telsa's Destination Chargers -- they call them Gen 3 -- somehow have a J1772 plug in addition to the regular Tesla plug. I haven't really looked for one of them out in the wild, but Kyle with Out of Spec Motoring saw one in Lake Tahoe: (link goes right to the relevant part).

My understanding is Tesla has for years offered to property owners to install ClipperCreek J1772 chargers alongside Destination Chargers. But if every Destination Charger will eventually have a J1772 as well, that would be huge for non-Tesla EV drivers.
