The AD-BMSE2E3WLC-SL Solution Kit is a cost-competitive, system-level reference design developed for medium- to high-performance Battery Management System (BMS) applications in Electric 2-Wheeler (E2W) and Electric 3-Wheeler (E3W) platforms. Designed for battery systems operating from 36V to 96V and supporting currents up to 100A, the solution combines accurate battery monitoring, current sensing, protection, and system control into a flexible development platform. The kit leverages the automotive-grade ADBMS1816W battery monitoring IC to provide precise cell-voltage measurement, temperature monitoring, and pack-level diagnostics, enabling developers to evaluate and accelerate the implementation of advanced BMS functions for a wide range of battery chemistries, including Li-ion, LiFePO4, Ni-MH, and Sodium-Ion batteries.

The solution kit consists of two primary hardware components: the AD-BMSE2E3WLC-48V baseboard, which integrates current sensing, power-path control, communication interfaces, and system-level BMS functionality and the EVAL-ADBMS1816WLC daughterboard, which expands cell-monitoring capability and enables support for higher cell-count battery packs. The package also includes the MAX32666FTHR microcontroller board, which executes BMS algorithms and provides USB-to-SPI communication for GUI interaction and two DC2472A Battery Emulator boards for evaluation and testing purposes, allowing users to simulate battery-cell voltages without connecting an actual battery pack. ​

Featuring built-in charge and discharge control circuitry with both high-side and low-side current sensing, the AD-BMSE2E3WLC-SL supports accurate State of Charge (SoC) and State of Health (SoH) estimation while providing the flexibility to implement centralized, distributed, or modular BMS architectures. Its modular and stackable design supports standard Arduino and Feather form factors, allowing users to integrate their preferred MCU platforms with minimal hardware modification. The system is further enhanced by daisy-chain-ready isoSPI connectivity, enabling scalable battery monitoring solutions for larger systems.

To accelerate development, this reference design also includes open-source firmware examples and a comprehensive PC-based graphical user interface (GUI) that provides real-time monitoring, diagnostics, configuration, and data visualization capabilities.
