ADBMS1818ASWAZ-RL is a multi-cell battery monitor, which can measure up to 18 cells in series, and the total measurement error (TME) is less than 3.0 mV. Battery measurement range The voltage range of 0 V to 5 V makes ADBMS1818 suitable for most battery chemistry. All 18 batteries can be measured within 290 seconds, and the acquisition rate of lower data can be selected to achieve high noise reduction.

ADBMS1818ASWAZ-RL  devices can be connected in series, which allows synchronous battery monitoring of high-voltage batteries for a long time. Each ADBMS1818 has an isoSPI interface for high speed, RF immunity and long-distance communication. A plurality of devices are connected in daisy chain, and all devices are connected through a host processor. This daisy chain can operate in both directions, ensuring communication integrity, even in the event of failure.

ADBMS1818ASWAZ-RL can be powered directly by the battery pack or from an independent power supply. The ADBMS1818 provides passive balance for each battery cell, and has independent pulse width modulation (PWM) duty cycle control for each battery. Other features include an on-board 5 V regulator, nine general-purpose I/O lines and a sleep mode, in which power consumption is reduced to 6 A..
