Does anyone out there have experience with a Think City- I am having
a charging issue with the Activa charger. I know it's a stretch..



Thanks,

Mark

What seems to be the problem?
Even though chargers differ, the batteries that need the
charge usually behave in the same way, so we can start
from what we know.

Here is some history,

Here is the progression of events as best as I remember:

1) When we received the cars I think the charge light was lit on the
dash when the car was first seen in the container, upon further
inspection the charge indicated about 20%

2) we drove them to our location and it was just in the first red
area after that

3) The car was plugged in several times and a fan could be heard, we
left it over night

4) the next morning the car was not charged and the plug was removed
and replaced several times and then I put the diagnostic meter in and
the charge started to read voltage and amps and so did the BMS system.

5) The car was left for several hours and it charged to about 65% and
was then driven down to 20% to move it.

6) The car was then plugged in immediately and charged to about 40%
where it seemed to stop at which point I used the meter and here is
what happened:

Charger settings could not be read from diagnostic tool due to
"communication error" most likely due to charger not working

BMS could be read and read no charging into pack

BMS had the following errors read on screen exactly as listed:


ISOLATION FAULT


I cleaned the drain tubes for the safts and reset the codes and all
BMS and other faults are gone, still can't access charger settings




I have tried multiple charge attempts to no avail- all fuses seem good.

After much frustration I disconnected the charger line at the HV
distribution box and hooked up my PFC 30, I charged at 5A and a
voltage just above the pack, this read as a charge on the BMS and
brought the car to 30% from 20%. I did not want to charge more using
this charger. This seemed to indicate that the contactors are working
and pack can be charged from those connections closest to charger.
The charger does get signals from the BMS and other locations.

So at this point I don't know if something is telling the charger not
to come on or if it is broken. Since there are no BMS errors I'm not
sure if that is the issue. The pack is only a year or so old and
should be fine. The charger is a Activa energy J71.
