![]() However, today’s lead-acid battery designs do not accurately measure and report current battery capacity, which often frustrates the end user, and could mean adding more batteries to keep the system adequately charged. Lead-acid batteries typically behave better than lithium chemistries in environments with wide temperature ranges. The highly accurate, simple-to-use gauge supports batteries used in mobile and stationary applications like medical instruments, wireless base stations and telecom shelters, e-bikes, inverters and uninterruptible power supplies.ĩ5-percent accurate monitoring for lead acid The bq34z110 gas gauge IC, which comes in a small 14-pin package, is the industry’s only scalable power management device to support multi-cell lead-acid battery packs with battery voltages of 4 V, 12 V, 24 V, 48 V and higher. The BQ25886 is a standalone solution with PowerPath and OTG.Texas Instruments announce the first lead-acid battery management gas gauge integrated circuit with TI’s proprietary Impedance Track capacity measurement technology for lead acid batteries. The BQ25886 is a highly-integrated 2-A boost switch-mode battery charge management and system PowerPath management which enables instant power on and provides accurate termination control device for 2-cell (2s) Li-Ion and Li-polymer battery.
