The temperature of the LFP cells
What is the operating temperature of the LFP cells?
The operating temperature of the LFP cells is based on the specification and the application. There are several points to be clarified in this matter. The first to clarify is the three different temperatures in relation to the batteries.
The ambient temperature
The ambient temperature is usually given as the air temperature of any environment where the batteries and related equipment are kept. The ambient temperature is given at the specification of the cells. It is also called the operation temperature.
The cells can be stored and operated within these temperature limits. However the performance of the cells is dependent on the temperature so the performance of the battery differs in various temperatures. In simple words, when the cell is cold (bellow zero) the performance is limited, when the cell is hot (above 40 °C) the drain of the cell must be limited as well in order to protect against overheating.
