Analog Devices Inc. AD-BMSE2E3W-SL Evaluation Board
Analog Devices Inc. AD-BMSE2E3W-SL Evaluation Board is a complete Battery Management System (BMS) reference design for Light Electric Vehicles (LEVs). This board offers a 72V to 96V regulated voltage range, up to 100A current capacity, and Low-Power Cell Monitoring (LPCM) capability. The AD-BMSE2E3W-SL integrated single-board system features the ADBMS6830 16-cell monitor, ADBMS2950 pack current monitor, ADBMS6822 isoSPI transceiver, and MAX32690 microcontroller. This evaluation board performs in embedded mode or using a GUI to calculate the battery's SoC and State of Health (SoH) through an enhanced coulomb counting technique. Typical applications include electric and hybrid 2-wheeler vehicles, and electric and hybrid 3-wheeler vehicles.
