Wired, Wireless, & Contactless: Comparing BMS Design Approaches

Abstract

Aggressive, worldwide net-zero targets are driving up the manufacturing throughput of larger and more efficient stationary battery energy storage systems (BESS) and a wider range of electric vehicles (EVs).

It is increasingly important for BESS and EV manufacturers to employ cost-efficient battery management system (BMS) designs that maximize the usable energy from the cells during their life, while also improving control over the safety and reliability of battery packs to meet warranty obligations or alleviate any simmering public concerns.

This white paper discusses three different BMS hardware design approaches: fully wired, far field wireless, and near field contactless; investigating and comparing the cost-efficiency, safety, and reliability aspects of each.
