✨ Key Product Innovations & Highlights
⚖️ 1A High-Efficiency Transformer Active Balancing
Unlike traditional passive balancing that wastes energy as heat, the 16HDA BMS adopts a transformer-based bidirectional active balancing system delivering up to 1A balancing current. This rapidly equalizes cell voltage differences ($\pm3\text{mV}$ precision at $25^\circ\text{C}$) with minimal energy loss, extending battery lifespan and maximizing usable capacity.
🔋 Heavy-Duty Power & Ultra-Compact Architecture
-
200A Continuous Discharge for over 1 hour; 400A Peak Discharge (>1 min).
-
2000A Short-Circuit Breaking Capacity to guard against extreme fault conditions.
-
Ultra-Compact Form Factor (214 mm×100 mm× 22.6 mm), significantly smaller than standard market alternatives, allowing easy installation into sleek wall-mounted or stacked battery cabinets.
🔗 Seamless Multi-Pack Parallelization (Up to 16 Packs)
Featuring an integrated 10A current-limiting module and onboard 4-bit DIP switch addressing, the 16HDA system allows up to 16 battery packs to be connected in parallel without risk of massive cross-pack circulating currents during startup or load spikes.
📱 4.3-Inch HD Touchscreen & Multi-Protocol Connectivity
-
Interactive 800×480 HD Touch Display: Real-time display of pack voltage, current, state of charge (SoC), temperatures, and fault alarms with customizable UI and OEM logo options.
-
Comprehensive Protocol Support: Native integration with CAN, dual RS485, RS232/TTL ports, and pre-loaded protocols compatible with all mainstream residential inverters/PCS units.
-
Smart Diagnostics: Built-in BLE for quick local mobile app debugging (ANT BMS V2 App) and external tri-color LED power button for quick SoC and system status inspection.
🛡️ All-Weather Protection & Heating Management
-
4-Channel NTC Sensing: Real-time monitoring of cells, MOSFETs, and ambient temperatures.
-
Optional 10A Integrated Electric Heating: Automated low-temperature heating control with $5^\circ\text{C}$ hysteresis to prevent frequent cycling and ensure safe charging under freezing conditions.
-
PWM Pre-Charge & Dual Relay Dry Contacts: Built-in PWM pre-charge circuit prevents high inrush current and spark formation when connecting to heavy capacitive inverter loads.
