ADES1830CCSZ-RL

ADES1830CCSZ-RL is a multicell battery stack monitor that measures up to 16 series connected battery cells with a lifetime total measurement error (TME) of less than 2mV for the ADES1830 over the full temperature range. The measurement input range of -2V to +5.5V makes the ADES1830 suitable for most battery chemistries and allows the measurement of voltages across bus bars. Provisions are made for bypassing bus bars without dedicating any measurement channels. All cells can be measured simultaneously and redundantly with two individual analogue-to-digital converters (ADCs). The continuously operating ADCs with a high sampling rate of 4.096MHz allow reduced external analogue filtering and aliasing-free measurement results. Higher noise reduction can be achieved by subsequent programmable infinite impulse response (IIR) filters. Applications include utility energy storage, commercial and Industrial energy storage, residential energy storage, backup battery systems.
