Smart BMS Protection Architecture
Our in-house developed BMS (model RYD-10S V1.0) provides comprehensive protection and intelligent battery management, ensuring optimal safety and performance in all operating conditions.
Over-Charge Protection
Over-Discharge Protection
Multi-level over-voltage protection (4.230V
/ 4.350V / 4.380V) with hardware and software redundancy.
Discharge cut-off at 2.800V per cell, with recovery voltage of 3.300V
Over-Current & Short Circuit
Primary 50A / Secondary 60A / Tertiary 80A protection. Short circuit response within 480µs.
Temperature Monitoring
NTC sensors (10KΩ B3435) with charge/discharge high/low temperature cut-off.
Cell Balancing
Passive balancing starts at 3.9V with
≥30mV difference. 42mA balance current.
