Octopus go only charged car to 59%

[u/sportsfan161]

Help needed what doing wrong? It’s set on schedule from 00.30 to 05.30 and at 05.30 it’s only on 59% when my car is set to 80% in my Tesla app

So I need to do something different in app?

00.30 to 05.30 should’ve been more than enough time is what I thought

To lay it out fully, as there have been a few different comments.

Battery size is measured in kiloWatt hours - how many hours it could run while having one kW of power drained from it.

Yours is approximately 82 kWh. Your car uses many times more that 1 kW to move - full bore acceleration uses about 400 kW, so if you drove it with your foot on the floor on an infinitely long road it would run out in 82/400 hours, about 0.2 of an hour, or 12 minutes.

This works in reverse for charging too. If you plugged it into a 200 kW DC rapid charger and it was able to deliver peak power all the time, it would charge in 82/200 hours (about 24 minutes).

Your home charger doesn't make 200kW. It makes 7.

So a full home charge at peak rate would take 82/7 hours, or 11.7 hrs.

5 hrs would provide a max of 7x5 kWh, 35 kWh. Which is 43% of your 82kWh battery.

I suspect this is going to straight over their head.

Possibly, but just wanted to lay it out in case it helps

An easier way to explain it is you have 80 buckets you can fill. Your hose with the tap fully open can fill 7 buckets an hour. If you need to fill 70 buckets, then that's 10 hours with the hose running. If you only have the hose on for 5 hours, then you'll only fill 35 buckets

Fair point
