Bosch Performance Line smart system charging

[Dreks]

Hi,
I hope you are doing well. I have a Bosch performance line smart system in my Haibike Trekking 3. I am experiencing an issue with charging. When the battery reaches 100%, it stops charging as it should. However, after some time, it starts charging again, just the last dot flashing. Should it be like this?

Thank you for your time and attention to this issue.

Hi, "Ebikeshop.co.uk" has all of the manuals available for Haibike Trekking 3. I don't know if this is where you shop or not but they seem like a good spot for information. If you download the battery manual just keep scrolling through until you get to the english section. The last dot charging is suppose to mean less than 10 percent charge needed. The battery may be going through balancing itself which is usually done after a full charge. If you have a multimeter you can read it's actual voltage state. A 36 volt ebike battery when charged to full, should be at 42 volts. You didn't say whether it was in or out of the bike at the time or whether you had unplugged it and then plugged it back in, either of these could effect it's battery management system. I'll post the relevant page I found.
