[FAQ] BQ34Z100-G1: Design Energy above Maximum

Part Number: BQ34Z100-G1

The maximum value for the Design Energy parameter is 32767 and in many high voltage battery configurations this value will be exceeded. In this case the parameter Design Energy Scale needs to be changed accordingly.  Design Energy Scale only affects energy related parameters.  These parameters are Design Energy, Reserve Energy(mW/cW), and User Rate(mW/cW). Current Scaling is not required in conjunction with Design Energy Scaling unless charging/discharging exceeds the 32 A that the gauge is rated for.

The value for the Design energy scale can be set to be greater than 10 however there will be an impact to the overall accuracy of the system.
