Battery Management System (BMS): The Core Safety Barrier of the New Energy Era Published: April 15, 2025 The Importance of BMS In the revolution of electrification and energy storage, BMS serves as the digital bridge connecting chemical energy and power systems. It defines the safety foundation, lifespan, and intelligent operation of batteries, supporting the infrastructure of the new energy industry. Core Functions & Architecture 8 Key Functions: Voltage/temperature monitoring, SOC/SOH estimation, fault protection, balancing control, communication (CAN/Modbus compatible). 3-Tier Structure: BMU (Cell-level data collection) BMC (Module control) BCU (System-wide strategy execution) Energy Storage Systems: Distributed BMS enables large-scale management. Technology Trends AI Integration: Neural networks and Kalman filters improve SOC/SOH accuracy. Cloud Connectivity: CATL’s cloud BMS enables OTA updates and predictive diagnostics. Functional Safety: Complies with ISO 26262, redundant sensors/power supplies. Domestic Chips: Rising adoption of MCU/AFE chips from Huawei, Jiefa, and Navitas. EV vs. Energy Storage: Design Differences Objectives EV: Safety-first (millisecond response), automotive-grade standards (vibration/temperature resistance). Energy Storage: Cost optimization, grid compliance (IEC 61850). Communication EV: Low-latency CAN bus/UDS protocols. Energy Storage: Modbus/Ethernet for large-scale data exchange. Cell Management EV: Active balancing (e.g., leapfrog capacity method) for strict uniformity. Energy Storage: Fault-tolerant designs for mixed-cell compatibility. Maintenance EV: OBD diagnostics, reliant on 4S shops. Energy Storage: Remote OTA/cloud diagnostics for unmanned operation. Industry Trends Regulations: GB/T 36276-2023 (energy storage safety standards), automotive EMC requirements. Key Players: CATL/CALB (in-house BMS), Prond/Lixin (OEM), TI/ADI (chip suppliers). Conclusion BMS is the "central nervous system" of new energy systems. With advancements in AI and cloud technology, it drives a smarter, safer energy future. Contact Us:

"Comprehensive Overview of Energy Storage System Architecture" Release Date: March 21, 2025, 20:00   I. Overall Architecture of Energy Storage Systems Energy storage systems consist of four core units that collaboratively achieve energy storage, conversion, and management: 1. Energy Storage Unit ◦ Function: Stores and releases electrical energy. ◦ Key Storage Media: ■ Lithium-ion batteries ■ Lead-acid batteries ■ Pumped hydro storage ■ Compressed air energy storage ■ Flywheel energy storage 2. Energy Conversion Unit ◦ Core Device: Power Conversion System (PCS) ◦ Role: Bidirectional AC/DC conversion: ■ Charging: AC → DC (grid → storage) ■ Discharging: DC → AC (storage → grid/load) 3. Energy Management Unit ◦ Function: The "brain" of the system: ■ Real-time data collection (storage capacity, charge/discharge status, grid load) ■ Optimization scheduling strategies ■ Coordinated control of multiple energy systems 4. Monitoring and Protection Unit ◦ Safety Mechanisms: ■ Real-time monitoring of voltage, current, and temperature ■ Abnormal condition alerts (overheating, overcharge/over-discharge) ■ Automatic cooling activation or circuit interruption   II. Energy Storage System Architecture Types 1. Centralized Energy Storage System ◦ Features: Large-capacity battery bank + centralized PCS ◦ Advantages: Simple structure, easy control ◦ Challenges: ■ "Bucket effect" (performance limited by the weakest cell) ■ Inter-cell loop current risks ■ Wider failure impact range ◦ Applications: Grid-side storage, large-scale renewable energy plants 2. Distributed Energy Storage System ◦ Features: Decentralized deployment + flexible grid connections ◦ Advantages: Localized supply-demand balancing, enhanced renewable energy integration ◦ Challenges: Complex coordination, higher maintenance costs ◦ Applications: User-side systems, microgrids, distributed power sources 3. String-Type Energy Storage System ◦ Features: Modular design + independent PCS (one string per controller) ◦ Strengths: ■ High efficiency (eliminates string current in
