Lithium Iron Phosphate (LiFePO4 or LFP) is an important lithium battery chemistry used in stationary energy storage applications.

LFP batteries are valued for their thermal characteristics, cycle-life potential and suitability for repeated charge and discharge operation when designed and operated within specified limits.

LiFePO4 technology is widely considered for commercial and industrial energy storage because of its characteristics and suitability for stationary battery applications.

Why Is LiFePO4 Used in Energy Storage Systems?

3. Understanding ESS Battery Voltage and Capacity

Battery voltage and capacity are important parameters when selecting or designing an energy storage system.

The battery configuration must be compatible with the power conversion system, BMS and intended application.

Important Battery Parameters

Voltage (V): Represents the electrical potential of the battery.

Capacity (Ah): Represents the battery’s electrical charge capacity.

Energy (kWh): Represents the amount of electrical energy stored.

Power (kW): Represents the rate at which electrical power is delivered or consumed.

C-Rate: Describes the charging or discharging current relative to the battery’s rated capacity.

How to Calculate Battery Energy

The basic nominal energy calculation is:

Battery Energy (Wh) = Battery Voltage (V) × Battery Capacity (Ah)

For example:

A 51.2V, 100Ah LiFePO4 battery has a nominal energy capacity of:

51.2 × 100 = 5,120 Wh

Therefore, the nominal energy capacity is 5.12 kWh.

Actual usable energy depends on the permitted depth of discharge, operating conditions and system losses.

4. Battery Energy Storage System (BESS) Architecture

A system rated at 100 kW / 215 kWh has:

Rated power: 100 kW
Nominal energy capacity: 215 kWh
Nominal energy-to-power ratio: 2.15 hours

This is a theoretical ratio, not a guaranteed backup duration. Actual operation depends on usable energy, discharge limits, load and conversion losses.
