D1000 Gen1 – Battery Management Unit (BMU)

Overview

The D1000 Gen1 Battery Management Unit (BMU) serves as the master controller in Prohelion’s distributed battery management architecture. In this system, multiple Cell Management Units (CMUs) are deployed throughout the battery pack to monitor individual cell groups locally, while the BMU acts as the central coordinator that aggregates data from all CMUs and manages system-wide operations. This distributed approach allows for scalable battery pack designs where CMUs handle local cell monitoring and balancing tasks, while the BMU provides unified control, safety management, and serves as the single communication point to the vehicle’s systems. Part of Prohelion’s comprehensive battery management system ecosystem, the D1000 Gen1 BMU delivers reliable battery pack control for demanding applications.

Key Features

• Central Communication Hub: Acts as a bridge between CMUs and vehicle CAN bus
• Contactor Control: Manages pre-charge and main contactors for safe battery pack operation
• Data Aggregation: Collates telemetry data from all battery nodes and provides summary information
• Safety Management: Includes precharge control with fault detection capabilities
• Compact Design: Space-efficient form factor suitable for integration into various vehicle platforms
