2. Long Cycle Life for Reliable Durability
Engineered for long-term value, the Calb 44.4V 147Ah Nmc 811 Battery Module demonstrates reliable durability with a cycle life of 500 cycles while maintaining ≥90% capacity and 1000 cycles while maintaining ≥80% capacity under specified test conditions, ensuring sustained performance and reduced total cost of ownership over its service life.
3. Robust Performance Across Wide Temperature Ranges
Built for resilience in diverse environments, the Calb 44.4V 147Ah Nmc 811 Battery Module supports a wide operational temperature range, allowing charging from -20°C to 55°C and discharging from -30°C to 55°C. This ensures stable power delivery and reliable operation in both extremely cold and hot climatic conditions.
4. High-Power Capability for Demanding Applications
The Calb 44.4V 147Ah Nmc 811 Battery Module is capable of high-power output, supporting a maximum continuous discharge current of 432A and a peak pulse discharge current of 1038A for up to 10 seconds. This makes it suitable for applications requiring high bursts of power, such as vehicle acceleration or handling peak loads.
Application:
1. Commercial Electric Vehicles (e.g., Buses, Trucks):
The Calb 44.4V 147Ah Nmc 811 Battery Module, with its high nominal energy of 6.54 kWh, robust cycle life (500 cycles with ≥90% capacity retention), and wide operating temperature range (charge: -20~55°C; discharge: -30~55°C), is an ideal power source for electric commercial vehicles, providing reliable range and durability for demanding daily operations.
2. Energy Storage Systems (ESS) for Renewable Integration:
Featuring a substantial capacity of 147Ah and excellent capacity recovery rates (e.g., ≥95% after 90 days at 45°C), the Calb 44.4V 147Ah Nmc 811 Battery Module is well-suited for residential, commercial, and grid-scale energy storage. It effectively stores energy from solar or wind sources, enabling load shifting, peak shaving, and backup power with long-term reliability.
3. High-Power Industrial Equipment (e.g., Forklifts, AGVs):
The Calb 44.4V 147Ah Nmc 811 Battery Module supports high-power demands with a maximum continuous discharge current of 432A and a peak pulse current of 1038A (for 10s). This makes it a perfect fit for electric forklifts, Automated Guided Vehicles (AGVs), and other heavy-duty industrial machinery that require sustained high output and frequent cycling.
4. Backup Power Supply for Critical Infrastructure:
With its defined State of Charge (SOC) operating window (5%-97%) and stable performance under storage conditions, the Calb 44.4V 147Ah Nmc 811 Battery Module can be configured into reliable Uninterruptible Power Supply (UPS) systems or backup power units for telecommunications base stations, data centers, and other critical facilities, ensuring operational continuity during grid outages.
