user defined data field

I'm the owner of a Garmin Edge 840 and driving an e-bike. I want to create a data field on the Garmin where I can monitor the amount of battery still needed to finish my activity.

It's something like "100 * distance left / distance to finish". Is this possible and what's the most easy way for a non expert ?

  • It is not so easy because the e-bike battery status is not reachable for CIQ datafields in an easy way.

    It depends what e-bike you have. You can access the battery state if your e-bike fulfills the ANT+ convention for LEV (Light Electric Vehicles). Some ebikes do this: Specialized, Fazua 50 system, Mahle X20 …
    But you have to code the communication process.

    Shimano Steps needs a BT communication to the CIQ datafield.

    If you have a Bosch motor, there is no way to get battery state into CIQ datafields.

    I have a datafield on the store for ANT+ LEV compatible bikes. It‘s called EDGE 1 EBIKE and it calculates the remaining range for the given battery state using the actual activity data.

  • In case it is still of interest:
    If you want to keep it simple - check how many watt hours you use per kilometer on average. It is usually 5 to 8 Wh/km. Then multiply the distance to destination by this value and you will get the battery capacity you still need (in Wh). You then can calculate the % of charge this are with your battery (i.e. 500 Wh).

    But this estimate is also easy to make by calculating in your head if you look at batterey % and the distance you have already covered Joy

  • I think that's exactly what he wanted to do. He asked for "100 * distance left / distance to finish" what my data field displays. He'll do the math for the battery (and knowing if he's downhill or uphill...)
