EV battery voltage ratings are trending upward from 400 V to 800 V, while those of large energy storage systems are increasing from 600 V-900 V toward 1,500 V. As test engineers evaluate hardware-in-the-loop (HIL) requirements for the battery management systems that manage these batteries, they face a trade-off between simulated cell channel count and simulation accuracy.
High-voltage lithium-ion battery packs for EVs and large ESS typically use a distributed BMS architecture comprising Battery Control Units (BCU) and Battery Management Units (BMU). Download this whitepaper to learn more about using ISO-SPI simulation technology to replicate interactions between BCU and BMU.
