Cannot Clear "E Bike battery low" warning

SimonElkington
over 1 year ago

I have an ebike with a Mahle ebikemotion x35+ system and a range extender battery. If either of these batteries drops to a low level a pop-up appears saying the battery is low (can't remember the exact words)

The pop-up can be cleared but it immediately re-appears. There does not appear to be a limit on the number of times this loop can repeat. Switching off the ebike or switching off and disconnecting range extender battery or both makes no difference - the pop-up re-appears. Through some rapid finger action it is just possible to stop the ride and save it. Then switching off the Edge Explore 2 and re-starting it clears the error message, although it will re-appear if the low battery state still exists.

A very annoying state of affairs...

1. This pop-up renders the unit useless when riding as it blocks the bottom of the screen, preventing access to the menu and disables the swipe left and right 

2. The whole point of the range extender battery is that it empties first to maintain the level in the main battery...

3. Its a redundant alert as the device displays remaining range

(All devices have the latest firmware)

Anyone know how to disable battery alerts? or know of a workaround.

Thanks

    I approached Garmin Support, this is the highlight...

    "So, Garmin devices reflect the behaviour on behalf of third party units. IF a third party device is constantly prompting a low battery, then the Garmin device will reflect that and let it's user know. Behaviour like this being exhibited is more likely to come from a third party source than from the edge unit directly."

    "I can get this raised further - so long as we have a video of the behaviour - but I'm not 100% confident it's something that we'll be able to fix, as there's a decent chance the problem is stemming from another source."

    As many other types of alerts can be disabled I then asked if a change request could be raised so that this alert type can be disabled.

    To make progress down either route we'll need video of the issue.

    So I have a 1030 plus and same thing happened to me this morning. Sooooo annoying being constantly told your battery is "critical" even though you have a range extender. Would this alert still pop up if you removed the battery % data field and just left the "travel range"?

    I finally manged to capture the issue on video so have submitted it to Garmin support. Interestingly the low battery warning continues to appear and re-appear even when the e-bike is no longer connected to the head unit. In my case the e-bike was switched off and is now about 100m away from the head unit but I still get the same looping issue. The suggests to me that the issue is with the head unit.

    I have the Edge 1040 with the latest SW and a bike with Mahle X20 and range extender and the same issue appeared in my recent ride. When the range extender was down to approximately 10%. Switching off the electric system did not clear the warning message and left the Edge device nearly useless.

    I've not heard back from Garmin tech support, so have chased them up. 

    For reference they asked me to provide them a ride file with extra information in it. If your battery is still in the low state or you know it is likely to happen on a ride it might be worth recording it as per below and raising a bug with Garmin.

    The team who are investigating the issue you are experiencing have come back to ask if they can collect some further information. The steps on how to do this can be found below:

    • Start an activity on your Edge.
    • Tap the screen. This will open a grey overlay page.
    • Press and hold the right arrow at the bottom of the overlay page for 5 seconds.
    • Select Fitness Logging.
    • Toggle ANT RX TX on.
    • ANT Logging is now enabled and ready for the next ride.
    • Press the START/STOP key to stop and discard the activity.
    • Start a new activity with the same sensors and phone connected.
    • Save the activity when you are done.
    • After you have saved the ride, send the Garmin folder and reply to this email letting us know that you have sent it. For instructions see Sending a Garmin Folder From a Device to Product Support

    Did you manage to send in this further information?  I too get this error message and I get it every time I switch on my battery even when it’s 100%.  Really frustrating having to keep hitting the screen of the garmin 830 to remove the message. I’ve tried everything to remove it and would love to get a fix.

    Not sure who you were asking the question of, anyhow from what you've written there are two things going on.

    1. Low battery warning when switching on the bike, something that appears to be a common issue - just a one click nuisance really.

    2. Being locked in a repeating loop when the range extender battery falls to a low level - which renders the head-unit useless.

    Please raise your issues as bugs with Garmin & they may prioritise fixing them.

    Thank you of for your response. Simon. It was you i was asking as to whether or not Garmin had done a fix for you. I assume not though, but thanks

    Hello Simon,

    just tried a workaround on edge 1030 and 1040:

    when you get the extender battery warning it means it is below 10% charge and the main battery near 100%.

    so you can turn off the extender, wait 1 or 2 second and clear the warning on the Garmin. It may require 2 or 3 clear if you are too fast.

    then you will get back’to full control of the Garmin.

    note that before that I also remove the extender battery sensor 352 from the Garmin sensor list, only kept the main 354.

    Enjoy
