Math calculation and simulation tool that helps the battery designer to obtain matching CEDV coefficients for the specific chemistry in the battery pack using one of TI’s CEDV algorithm based fuel gauge. It accepts 3 pairs of log files that can be created by using TI’s bq Smart Battery Builder software with a CEDV Evaluation board connected through USB. For accurate calculations it will also require some additional parameters of the battery pack setup. The downloadable output file contains the CEDV coefficients that can be programmed into Data Flash to create a golden image that can be used in mass production of battery packs.
An EV2300 or EV2400 PC interface board is required to interface to the gas gauge, and a PC USB cable is required for communication with a PC. Both can be ordered online at http://power.ti.com. Windows™-based PC software is available online as well. With the EV2300 or EV2400 interface board and software, the user can read the data registers, program the chipset for different configurations, log cycle data for further evaluation, and evaluate the overall functionality of the solution under different charge and discharge conditions
