DEMO_IMR_BMSPWR_V1 Demo board for BMS power, utilized in Infineon Mobile Robot (IMR)

概要

This 44.4 V nominal voltage demo board, with a voltage range between 30 V and 50.4 V and a charging and discharging rate of 1 C & 5 C, is delivered in a modular design by combining the DEMO_IMR_BMSPWR_V1 power board (on this page) and the DEMO_IMR_BMSCTRL_V1 controller board, with the required software. The IMR uses two modular BMS solutions, supporting hot-swapping of the batteries, meaning that the robot never has to be powered off.
