2. Key Performance Features of the LFP.6144.G2 Battery
1. Rated Voltage and Assembly Structure
The LFP.6144.G2 has a rated voltage of 51.2V, providing a stable and efficient power output. It features a modular design consisting of one main control box and two LFP.6144.GM battery modules, making the system easy to expand or service. The main control box manages the overall operation, including charge and discharge control and battery health monitoring, while the battery modules store the energy.
2. Charge/Discharge Rate (C-rate) vs. Battery Capacity (kWh)
The charge/discharge rate (C-rate) and battery capacity (kWh) are closely related but represent different aspects of battery performance.
C-rate refers to the rate at which a battery can be charged or discharged. For instance, a 1C rate means the battery can be fully charged or discharged in 1 hour. For a 100Ah battery, a 1C rate delivers a current of 100A, while a 0.5C rate discharges the battery over 2 hours with a current of 50A.
Battery capacity (kWh) represents the total energy the battery can store, calculated by the formula:
Battery capacity (kWh) = Battery voltage (V) × Battery capacity (Ah) / 1000
For LFP.6144.G2, with a voltage of 51.2V and a capacity of 240Ah, its energy storage capacity is:
12.28kWh = 51.2V × 240Ah / 1000
3. The Relationship Between C-rate and Capacity
While the C-rate influences how quickly a battery can deliver power, it doesn’t change the battery’s total capacity (kWh). However, the C-rate does determine how fast the battery can release its stored energy.
- Low C-rate batteries (e.g., 0.5C) store larger amounts of energy but discharge more slowly, which may limit their ability to power high-demand equipment.
- High C-rate batteries (e.g., 1C) release stored energy faster, making them more suitable for applications requiring significant power over shorter periods.
For example, a 10kWh battery with a 0.5C rate can provide a maximum of 5kW of power, while a 6kWh battery at 1C can deliver 6kW, offering greater power output in less time.
LFP.6144.G2 supports 1C charging and discharging, making it ideal for scenarios where fast energy delivery is essential, such as during power peaks or emergency backup.
4. Modular Design and Expandability
The LFP.6144.G2 system is designed to be modular, allowing up to 4 units to be stacked together. This increases the maximum discharge current to 300A and supports inverter outputs up to 15kW. This flexibility allows users to scale their energy storage systems based on their evolving needs, avoiding the need for an upfront large investment while still accommodating future expansion.
