EverExceed’s advanced LiFePO₄ battery solutions are designed to fully meet these demanding technical requirements, ensuring reliable power supply for 5G networks under diverse operating conditions.

Capacity Calculation & Key Influencing Factors

The required battery capacity for a 5G base station is not fixed; it depends mainly on station power consumption and backup duration.

Core Formula:

Required Capacity (kWh) = Peak Power Demand (kW) × Backup Hours (h)

Example:

If a 5G macro station has a peak power consumption of 5kW and requires 4 hours of backup time, with 90% Depth of Discharge (DoD), the required capacity would be:
5kW × 4h ÷ 90% ≈ 22.2 kWh

Key Factors Affecting Capacity:

· Station Type & Power Consumption: Macro stations consume 15–25kW, significantly higher than small cells (3–8kW). Main power consumers include AAU (Active Antenna Units) and CU/DU (Central/Distributed Units).

· Backup Time: Generally 2–4 hours, but longer durations may be required in critical sites or regions with unstable grid supply.

· Depth of Discharge (DoD): EverExceed LiFePO₄ batteries support 80–90% DoD, allowing efficient utilization of installed capacity.

· Temperature: High temperatures (above 35°C) reduce efficiency, requiring 10–15% additional capacity; low temperatures also affect discharge performance.

· Future Scalability: EverExceed’s modular battery design supports easy capacity expansion to meet future 5G traffic growth.

⚡ High Discharge Rate Requirements for 5G

C-rate (discharge rate) defines the relationship between discharge current and rated capacity, reflecting a battery’s ability to deliver power. 5G stations demand high discharge capability due to:

· AAU Peak Loads: Sudden surges during high-traffic periods.

· Network Traffic Bursts: Batteries must handle sharp increases in power demand.

· Fast Response: Especially in “smart peak-shaving” applications, where rapid response to grid fluctuations is required.

Typical Values:

5G Macro Station: Continuous discharge up to 500A.

Urban Small Cell: Peak discharge up to 150A.

EverExceed’s high-rate discharge LiFePO₄ batteries are engineered to handle these demanding conditions, ensuring stable and efficient power delivery to 5G infrastructure.
