Note that the 'aux battery saver' did not kick in overnight, as I might have expected. I'm assuming that the ~13 V was 'surface charge' as they say and that when I unlocked the doors the next morning at 1030 that was partly depleted. You can see that the aux battery was charging for the first 30 minutes. The car had been sitting for 5 days unused. On the first, actual Kona data starts at the far right, where an AC (7 amp) charge event started at 2100 hours, which I knew would take just under 2 hours to complete, noting the little glitch. I'm hoping to use this to characterise the 'aux battery saver' function and other conditions when the OBD port is not available. They say that's so it can connect automatically when you are within range and it's needed for the alerts. The leads are solid core wire so you don't want to leave it hanging.Īfter installing the app I did not enable location access while not using the app. Obviously the Blu-Tack is used to secure the logger onto the battery but any other means is just as valid. The spades need to be squeezed together carefully to encompass the 5mm stud. Using nyloc nuts assure they will not go astray if they happen to loosen. The existing post clamps have just enough exposed thread to attach the spades on top of the clamps nuts. All I needed additionally were (2) M5 low-profile nyloc nuts and a small lump of Blu-Tack. Fortunately, the install is an absolute breeze on the Kona EV and does not require loosening the post clamps, although you could do it that way. There are configurable low 'SoC' alerts as well but you have to be in range to get them immediately and so that feature may not be that useful for me, along with a couple of other inapplicable ICE-related options. While using the app within range it updates and graphs every second. A cursor is available as well but there is no apparent way to download the data. That data is accessible by the free app (both Android and iOS) when in Bluetooth range and is displayed on a graph in 24 hour segments, which you can screenshot. It logs voltage to internal memory every 2 minutes and overwrites old data after 31 days. It's a voltage logger for a 12V car battery and is connected permanently across the posts, drawing a mere 1mA. I bought this item because I noticed a UK owner had one on the SpeakEV forum.
