The BQ34Z100EVM is a is a complete evaluation system for the bq34z100 wide range fuel gauge for lithium ion chemistries when combined with an EV2300 USB adapter and Windows based PC software. The circuit module includes bq34z100 integrated circuit (IC) and all other components necessary to monitor and predict capacity in 1 or more series cell Li ion, Li polymer, or LiFePO4 battery packs. The circuit module connects directly across the battery. With the EV2300 interface adapter and software, it is possible to read the bq34z100 data registers, program the chip for different pack configurations, log cycling data for further evaluation, and evaluate the overall functionality of the bq34z100 solution under different charge and discharge conditions.
● Populated circuit module for quick setup
● Supports Li ion and LiFePO4 chemistries
● Capacity estimation using patented impedance track technology for batteries from 3V to 65V
● Supports battery capacities above 65Ahr
● Supports charge and discharge currents above 32A
● Supports two wire I2C and HDQ single wire communication
● SHA-1/HMAC authentication
● One or four LED direct display control
● Five LED and higher display through port expander
● Link to software allowing data logging for system analysis
●Applying a voltage higher than 5 V when jumpers are configured for 1S operation will very likely damage the IC.
