The BQ76PL102RGTT is a PowerLAN dual-cell Li-ion Battery Monitor with PowerPump cell balancing. It is for use with arrays of up to 12 Li-ion rechargeable cells. It connects to one or two cells in a series string, performs voltage and temperature monitoring of each individual cell and reports these parameters over the PowerLAN communication network. Together with a BQ78PL114 master-gateway battery controller, the bq76PL102 forms a complete battery monitoring and management system for higher cell-count applications. Partitioning of the battery monitor function on a per cell basis permits connection and measurement close to the cell. This results in superior accuracy and management over competing solutions. This scheme also facilitates the PowerPump cell balancing system, a technique which actively balances capacities of Li-ion batteries without the excessive heat or limitations of bleed-balancing techniques.
