I am considering using the BQ34Z100 to monitor a 48V LiFePo4 pack used for an electric bicycle.
I have purchased a BQ34Z100EVM and EV2300 and the time has come to open them up.
I have a couple of questions before I get started.
1. The EVM specs say that the board should not be subjected to more than 50V, yet the nominal voltage of my "48V" pack (16s, I believe) is slightly higher. Will I likely be OK or do i need to adjust the voltage divider on the EVM?
2. The EVM specs limit the current to 7A. My application routinely sees currents of 25A or more. Would it be acceptable to replace the on board shunt with an off board one that can handle the increase in power?
3. This is probably the most important question and possibly the dumbest. Is it absolutely necessary for this chip to be able to monitor the charge current into the battery? Is there some way to only monitor the discharge and some reset the chip to full after recharging the battery offline?
Thanks in advance for your help and patience.
