The AD-BMSE2E3W-SL is a BMS reference design for light electric vehicles (LEVs). With a voltage range of 72 V to 96 V, this solution is suitable for electric 2-wheeler and 3-wheeler vehicles with high current capacity ranging up to 100 A. ​​

This single-board system utilizes the best-in-class ADBMS6830 cell monitoring chip that is capable of monitoring up to 2x 16-channel. This board also features battery pack monitoring using the ADBMS2950. ​The ADBMS6822 dual isoSPI transceiver provides a built-in 2-wire reversible isoSPI connection, which simplifies the communication of BMS parts in a daisy chain configuration before sending the data to SPI lines in the microcontroller. ​​

The on-board MAX32690 MCU, when loaded with the firmware, can perform BMS measurements such as cell voltage (average and filtered), and pack voltage and pack current measurement. The board also has a charge, pre-charge, and discharge mode that can be controlled by the ADBMS2950 pack monitor chip.​

The AD-BMSE2E3W-SL is designed to perform either in embedded mode or using a GUI, where it calculates the battery's State of Charge (SoC) and State of Health (SoH) through enhanced coulomb counting technique.​

The EVAL-ADBMS6822 evaluation board is a dual SPI to 2- wire isolated serial-port interface (isoSPI) adapter featuring the ADBMS6822. Multiple ADBMS68xx battery monitors can be linked through daisy-chain interconnections. The EVAL-ADBMS6822 evaluation board also features reversible isoSPI, which enables a redundant communication path to the peripheral units. The PCB, components, and DuraClik™ connectors are optimized for low electromagnetic interference (EMI) susceptibility and emissions.

The EVAL-ADBMS6822 evaluation board can communicate to a PC by connecting together with EVAL-SDP-CK1Z. The EVALADBMS6822 evaluation board provides a standard SPI, which can be translated to isoSPI and then onward to a peripheral device or daisy chain as applicable.

The EVAL-ADBMS6822 evaluation board can also be used to evaluate the ADBMS6821. Note that, for the ADBMS6821, there is only one SPI port; therefore, ignore the second SPI port and auxiliary isoSPI port when using the ADBMS6821.

Full specifications on the ADBMS6822 dual isoSPI adapter are available in the ADBMS6821/ADBMS6822 data sheet available from Analog Devices, Inc., and must be consulted with this user guide when using the EVAL-ADBMS6822 evaluation board.
