ROBUST BMS SOLUTION

Ensures Safe Operation of Li-Ion Battery Packs While Reducing System Cost

Our groundbreaking BMS architecture provides the most comprehensive safety and reliability available while greatly reducing

system cost. It employs a low-power, capacitively coupled daisy chain to overcome the shortcomings of current-driven

architectures.

At the heart of the system is Maxim’s fourth-generation high-voltage battery-management IC (MAX17823). This daisy-chainable

12-cell device integrates a full suite of ISO-26262 diagnostic features to ensure ASIL D compliance. To minimize isolation

requirements, our proprietary architecture utilizes a unidirectional, diﬀerential UART-to-SPI bridge (MAX17841B) to provide a

robust interface between the cell monitoring ICs and the BMS microprocessor’s SPI port. This approach only requires one pair of

low-cost transformers at the bottom of the daisy chain to achieve galvanic isolation for the high-voltage electronics. In contrast,

current-driven architectures require isolation transformers at each BMS monitoring IC, imposing a signiﬁcant cost penalty.

Additionally, Maxim’s proprietary daisy chain achieves the fastest speeds for cell-stack measurements and ASIL diagnostics.

This gives you the most accurate synchronization to pack current measurements and, therefore, most accurate state-of-charge

estimation. The result is higher battery service life, higher driving range per charge, and lower system cost.
