Texas Instruments (TI) has launched BQ79826Z-Q1 – the latest addition to its battery monitor portfolio that features an EIS engine alongside the industry-leading number of cells to enhance battery safety, performance, and lifecycle in EVs and ESS. This advanced battery monitor will provide diagnostics and predictive intelligence by offering better insight into the chemical health of the cells, thus detecting faults well ahead of time. This innovative device is capable of monitoring up to 26 cells per device, which is eight cells more than any other competitor, meaning it offers 44 percent additional channel monitoring than previous iterations, saving space on the PCB. “The electrification of transportation and the rapid expansion of energy storage are redefining what battery performance must deliver, and as a leader in battery management technology, TI is uniquely positioned to meet that challenge,” said Wenjia Liu, vice president and general manager, battery management systems (BMS) at TI.
