BMS Description
Due to lithium batteries’ high volumetric and energy density, along with single-cell voltages up to 4.2V, they have been widely adopted in portable electronic devices such as mobile phones, PDAs, and digital cameras. To ensure operational safety, lithium battery applications must include battery management circuits to prevent overcharging, over-discharging, overheating, and overcurrent conditions. Lithium battery protection ICs, with their ultra-small packaging and minimal external component requirements, are widely used in lithium battery protection circuit design.
Advantages
Built-in high-precision voltage detection
High-Precision Voltage Detection A sophisticated voltage monitoring system that continuously measures individual cell voltages with high accuracy (typically ±0.5% or better), enabling precise cell balancing and protection against over/under voltage conditions.
Temperature protection
Temperature Protection Comprehensive thermal management system incorporating multiple temperature sensors and protective algorithms to monitor and regulate battery temperature, preventing thermal runaway and ensuring safe operation across various conditions.
Built-in three-stage discharge overcurrent detection
Three-Stage Discharge Overcurrent Protection Multi-level current monitoring system featuring three distinct thresholds for discharge protection: warning level, protection level, and emergency cutoff, providing graduated response to different overcurrent scenarios.
Charging overcurrent detection
Charging Overcurrent Detection Advanced charging current monitoring system that quickly identifies and responds to abnormal charging currents, protecting cells from damage due to excessive charging rates or faulty charging equipment.
Independent charge/discharge over-temperature threshold settings
Independent Charge/Discharge Temperature Thresholds Separate temperature threshold settings for charging and discharging operations, allowing optimized performance and protection based on the different thermal characteristics of charge and discharge cycles.
Integrated battery connection wire break detection
Integrated Wire Break Detection Real-time monitoring system for detecting disconnections or poor connections in battery pack wiring, featuring automatic fault detection and reporting capabilities to prevent system failures and ensure reliable operation.
