🌟 Key Highlights & Technological Breakthroughs
⚡ 1. Advanced Split Architecture for Optimal Safety
-
Decoupled Control & Sensing: By isolating high-voltage switching and system control (90AKA Master) from cell sampling (13PNA Slave), the system minimizes signal interference and elevates overall thermal and electrical safety.
-
Modular Multi-Slave Expansion: Supports up to 8 daisy-chained slave units (up to 104S equivalent configuration), providing seamless adaptability for light electric vehicles, heavy industrial machinery, and stationary battery energy storage systems (BESS).
🎯 2. Ultra-High Precision Sensing & Passive Balancing
-
Millivolt-Level Accuracy: The 13PNA slave board delivers cell voltage detection across 0–5V with a typical error of <10mV (max error <20mV) and a 1mV resolution.
-
Adaptive Passive Balancing: Integrated passive balancing (up to 200mA/channel) maintains cell consistency, prolonging battery pack lifespan.
-
Multi-Point Thermal Monitoring: Each slave module supports up to 4 external temperature sensors for comprehensive thermal mapping across cells, ambient environments, and MOSFET components.
🔋 3. Universal Chemistry & Multi-Profile Switching
-
Full Battery Compatibility: Native support for Lithium-ion (NCM), Lithium Iron Phosphate ($LiFePO_4$), Lithium Titanate (LTO), and Sodium-ion (Na-ion) chemistries.
-
Dual Parameter Profiles: Supports embedded dual parameter configurations, allowing operators to switch system parameters instantly with a single button via software.
🔌 4. Robust High-Power Control & Protection
-
High-Current Handling: Equipped with 3-pair high-power MOSFETs handling up to 300A peak current (10s) and 150A continuous discharge with optimized thermal dissipation.
-
Multi-Relay Management: Dedicated 4-channel relay drivers for charging, discharging, pre-charging (inrush current mitigation), and electric heating elements.
-
2-Stage Circuit Protection: Comprehensive safeguards including 2-stage overvoltage, 2-stage overcurrent, undervoltage, short-circuit, and overload protection.
🌐 5. Smart IoT Telematics & Multi-Platform Monitoring
-
Industrial Communication Protocol: Features isolated CAN2.0A/B (JN1939), RS485 (2500V isolation), TTL, and DI/DO customization.
-
GNSS Cloud Tracking: Built-in GNSS port enables real-time location tracking, cloud-based fleet management, remote diagnostic logging, and OTA firmware updates.
-
Wireless Mobile & Desktop Controls: Integrated Bluetooth connectivity connects effortlessly to iOS, Android, Huawei Mobile Apps, and Windows PC host tools for real-time monitoring and fault log retrieval (up to 400 cycle logs).
