Backup for 48V LiFePO4 Rack Battery

The backup function of the 48V LiFePO4 Rack Battery refers to the ability of the battery system to quickly switch to the power supply state when the main power supply (such as power grid, main generator) is interrupted, ensuring the continuous operation of critical equipment or loads. Its functional design revolves around reliability, response speed, and adaptability, as follows:
1. Core standby power function
Fast power-off switching to ensure power supply continuity
Equipped with intelligent switching modules (such as ATS automatic transfer switch or DC/AC conversion unit), when the main power supply voltage is abnormal (power failure, undervoltage, overvoltage), it can switch to battery power mode within milliseconds (usually < 10ms) to avoid sensitive equipment restart or data loss due to power failure (such as servers, communication base stations, monitoring systems).
It supports "zero switchover" design, especially for scenarios with very low tolerance for power interruptions (e.g., medical devices, industrial control units).
The stable output is matched to the load
The 48V DC output can be directly adapted to DC loads (such as 48V base station equipment, network switches, and security cameras in communication equipment rooms) without additional conversion, reducing energy loss.
If AC loads are to be driven (e.g. small office equipment, emergency lighting), an inverter module can be integrated to output 220V/110V AC, compatible with a wide range of load types, covering a range of several hundred watts to several kilowatts (depending on battery capacity and module configuration).
On-demand battery life and capacity management
Based on the high cycle life (typically > 3000 cycles) and stable capacity characteristics of lithium iron phosphate battery (LiFePO4), the standby battery life can be calculated based on the load power (e.g., 1000W load with 10kWh battery, the theoretical range is about 10 hours).
The integrated battery management system (BMS) monitors the battery SOC (state of charge) in real time and visualizes the remaining battery life via a local display or remote platform, allowing users to plan ahead (e.g. starting the generator in time or reducing unnecessary loads).
Smart charging and self-maintenance
After the main power supply is restored, the system automatically switches back to the charging mode, and the BMS controls the charging current and voltage to avoid overcharging, and at the same time balances the status of each cell of the battery pack to prolong the service life.
It supports "floating charge mode", which maintains the full state of the battery with a small current in the long-term standby state (when the main power supply is normal), ensuring that it can be put into use immediately when the power is cut off, and reducing capacity attenuation.
2. Accessibility and Benefits
High level of security
Lithium iron phosphate batteries have the characteristics of high thermal stability, strong overcharge and over-discharge tolerance, and cooperate with the functions of BMS such as over-temperature protection, short-circuit protection, and over-current protection to reduce the safety risk during standby power supply.
The rack-mount design (typically fits into a standard 19-inch cabinet) saves space, and some products have built-in fire isolation or temperature warning devices to adapt to tight environments such as equipment rooms and power distribution rooms.
