Re: State of Charge % incorrect
Was told the same from Custom Golf Carts in Mesa AZ

Re: State of Charge % incorrect
UPDATE: I talked with a mechanic at our (North Florida Custom Carts) and he said they will come and swap out the dashboard. Stated that it was a simple fix to the problem. I will update again after the holidays when it is done.

Re: State of Charge % incorrect
I received a printout from my dealer that stated when this issue occurs follow the procedure CSS899 detailed and it has set mine back to 100% every time. Plug it back it, wait for the red light to come on, turn the key on, it will show 100%, turn the key off, unplug, and you are good to go. Def curious about the long term fix though so hopefully someone will follow up about the dash/charger firmware update. THANKS!

Re: State of Charge % incorrect
Hello, Back with an update. Our dealer (North Florida Custom Carts) came out Monday 1/4 to replace the dashboard on our i40. Simple fix that took less than 5 minutes. Everything has been working fine since the replacement. Dealer rep who came out said Icon told them they don't understand the problem but they sent out several new dashboards to replace old ones. So far so good.

Has the issue resurfaced since the dashboard replacement? I was just told by North Florida Custom Carts that there is no fix. I am not happy with this response. "According to ICON there is an algorithm issue stemming from a charging voltage deviation that cropped up when they made the switch to Trojan batteries and chargers from U.S. Batteries and we were informed this morning that there is no resolution to the persistent charge percentage display problem. Maybe at some point it’ll be resolved but we simply don’t know when. It doesn’t affect the performance of the cart only the accuracy of the information center." |

From a technical standpoint...it's incredibly difficult to get accurate readings, especially from a company the size of ICON. I have family that worked for Tesla specifically trying to improve their battery capacity calculations. Here's some info from a battery scientist that goes into it some: Quote:

So far the problem has not resurfaced. So far so good.

Re: State of Charge % incorrect
There's an ICON group on FB and one of the ICON founders is an active member and super helpful with all kinds of info - and even shipping replacement parts directly to members of the group. Here's his very similar response:
"Tech update: After much in-house testing, and additional testing at several of our dealers, we believe we have resolved the issue of some charge meters not resetting to 100% after a full charge cycle. It seems what is happening is that the state of charge meter needs to cross the 51 volt threshold in order to reset to 100%, but the current Trojan algorithm is only charging to within .5 of that number. So to use a gas tank analogy, your tank is filling up to 99%, but not triggering the gauge to read "full". You still have 99% of your available range after charging, but the meter just doesn't know it. So they are writing a new charging algorithm for us, which we should have relatively soon. In the meantime, your dealers can substitute a US battery algorithm in its place, or wait for the updated Trojan algorithm. We apologize for the inconvenience, but we wanted to make sure of what actually was happening. We were initially a bit puzzled because exchanging meters worked in the beginning for some carts, but not others. So we needed to confirm if it was a meter issue, a battery issue, a charger issue, or an algorithm / software issue, or some combination of some or all of them. And also credit goes to a few folks here who were right on the money with their thoughts about what the issue was. This group is awesome!" Also, FWIW, I got my cart from NFCC and have been very happy with their service. Tammy is on this FB group too as is another member of her staff. I'd recommend it to anyone as there are a bunch of ICON dealers there and some folks who are fabricating bolt-on specific accessories for ICONs - like a 2" hitch receiver and nerf/step bars. |

Re: State of Charge % incorrect
Been dealing with this very issue for six months. I really hope they will release the software update soon so my dealer can try again.

Re: State of Charge % incorrect
For those with battery issues - list your battery brand/model, individual battery voltage, and # of batteries in your cart.
My hunch is still a charger software issue. If anyone missed the picture before, that's how they program the charger...they click that dropdown and select the battery configuration. It appears SUPER easy to accidentally choose the wrong battery config. I think those different battery profiles tell the charger how much to charge the pack. So if you have Trojan T-105's, your (theoretical) fully charged float voltage should be 52.8v, but if you have T-875's your total should be 54v! So if you have six 8v T-875's, but your charger is mistakenly programmed for the T-105's, then the charger may only charge up to 52.8v instead of the full 54v. My theory may be correct for some of you, and for others, you may have a completely different issue. My theory can be tested though with a multimeter and a fully charged (green light) cart. I just looked up the manufacturer battery data sheets and verified my cart (8x6v T105's) matches that float amount and the individual batteries measured 6.58v (target 6.6v). |
