While I have not worked on a Think. It sounds like your describing a
Balancing/Leveling charge. This requires you leave the vehicle plugged until the
BMS tops off all cells. This is not going to use much energy but it can
take a long time to balance cells.
If you deeply discharge a pack there is a much greater chance of them
becoming out of balance. For long life all battery manufacturers recommend not
to discharge below 80% SOC. If you really want to extend the life of your
pack try and keep the SOC between 40% to 80%. It will add thousands of cycles
to your pack if your use allows doing so.
Congratulations to you and all the other Think owners.

Yeah, the radio. Not exactly intuitive is it?
I read the auto manual cover to cover last night. Pretty good overall.
Here's a question: They gave me a L1 charger that looked different from
the ones I saw in most of the other cars. Its a large green Levitron. 12
Amp. Charged 12 hours (starting at 80% full) and never turned itself off.
I can only imagine that the last bit of power to raise the level from 99%
to 100% is asymptotic: takes an hour to do 1/2% then another hour to do 1/2
of a 1/2, then another hour to do 1/2 of a 1/2 of a 1/2, etc. When does
the charger know when to turn itself off?
