Distributed High Voltage BMS

INTRODUCTION

Idneo’s DISTRECO is a high-accuracy distributed BMS that can manage several battery slaves with a maximum of 18  cells per slave and total voltage up
to 1500 V. The safety level of the BMS is ASIL-C rated with same actuation mechanism of the contactors and Pyro-switches.
Open API interface to include custom battery SOC, SOH or SOP algorithms.
