AD-BMSE2E3W-SL

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