Hi
hope someone can please give me a few pointers.
my config is a 4 serial x 2 parallel LION battery of 4500mAh. my max voltage is 16.8 volts when charging.
I have been for many long days now trying to complete the learning Algorithm for the bq34z100. I can get the update status to get to 5 but no matter how many times i try it never goes to 6.
here is the process i'm following as given by Tom from a previous post.
Set your Flash Update OK voltage to 2000mV. Set the FConvEn bit to 0 in the Pack Cfg B register.
1. Send an IT Enable (21) command to turn ON FETs. Send a Reset command (41) to disable Ra-table updates.
2. Discharge to empty
3. Wait until the OCVTAKEN flag turns red.
4. Send IT Enable command to set a DOD0 reference point.
5. Charge to full (FC bit set.)
6. Wait until the OCVTAKEN flag turns red. You should see VOK turn green after Qmax has learned. You should see Update Status change to a 05.
7. Discharge at a C/8 rate down to Term Voltage.
8. Wait until the OCVTAKEN flag turns red. You should see Update Status change to a 06 during the rest period.
if the process fails at what point in the list do i start the process again. I have been reloading the senc file and calibrating the board. but if theres a better way of trying the algorithm again could you decribe it please.
i would great appreciate some pointers to where i'm going wrong.
attached is the .gg file of my config and current state.
