Battery Management System Solution


The DNB1168 Battery Management System integrates the function of monitoring the voltage of battery cell, impedance of the cell and the temperature of the cell, which can be used by the pack-controller to evaluate the SOC/SOH/SOF of the cell with a high precision. This chip measures the internal temperature of the cell through dedicated circuit technique, which is extremely important for the measuring of SOC of the cell, while traditional chip cannot provide such function. And also this BMS provides on-chip balancing function to eliminate the imbalance between different battery cells to extend the life of the battery pack. This BMS offers a single-wire communication to pack controller to construct a battery pack with extremely less wires compare to traditional battery management system to reduce the cost.

The Technology used allows for high junction temperatures as well as below ground operation in order to realize a robust device perfectly suitable for application in harsh automotive environments.
