Product Details
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.
