M48 Gen1 – Battery Management System (BMS) – 16S 100A

Overview

The M48 Gen1 Battery Management System represents Prohelion’s centralized (but modular) battery management solution, specifically designed for <16S 48V nominal lithium battery systems. Unlike the distributed D1000 architecture that uses separate BMU and CMU units, the M48 employs a unified centralized approach where all monitoring, balancing, and control functions are integrated into a single intelligent unit. This design is optimized for applications requiring up to 16 series-connected cells (57.8V nominal), offering comprehensive battery pack management with 100A switching capability, intelligent balancing algorithms, and precise state-of-charge estimation for maximum energy utilization.

Key Features

• Centralized Architecture: All-in-one design with integrated monitoring, balancing, and control functions
• 16-Channel Monitoring: Comprehensive voltage sensing for up to 16 series-connected lithium cells
• Intelligent Balancing: Advanced algorithms with 666mA external balance current for optimal cell equilibrium
• High Current Switching: 100A continuous charge/discharge current capability with complete load control
• Precise SOC Estimation: Ultra-precise current sensing combined with intelligent algorithms for accurate state-of-charge
• Comprehensive Protection: Software-configurable over/under voltage, current, and temperature protection
• Temperature Monitoring: 8 NTC thermistors for critical point monitoring and FET temperature sensing
• Low Power Consumption: 30mA max operation, 4µA sleep mode for minimal parasitic drain
