Added energy is missing from beginning of charging session

Veritas1980 3 years ago updated 3 years ago 2

I was wondering why my charging sessions at home showed very low efficiency in the beginning of a charge, and then evened more out over time.

It looks like it Teslafi does not count added energy in the first 5 minutes or so. The battery range and level is clearly going up, but the charge energy added is not counting.

Hi.  Unfortunately this is not on TeslaFi's end.  The data comes directly from the API minute by minute and I'm not seeing this with my vehicle or a couple test vehicles I just checked.  When you start a charge you can view the raw API data by going to settings->account->advanced->view raw tesla api output and you'll see the same information that appears in the raw data page coming from the API.


It's possible that a reset of the vehicle could resolve it or it's a bug with 2018.6.1 641efac and your vehicle.  Or it's the battery management system adjusting the battery range at the beginning of the charge.  Unfortunately I don't have a definitive answer since there is no support from Tesla on the API.

It's been going on for a while I can see, so I don't think it is specific for this firmware. I wasn't aware it was API sending the data.


Thanks for the reply.
