FAQ: Can LiFePO4 cells be charged with impulse DC current? (Most lead-acid batteries prefer to be charged with trickling currents – which increases their lifespan.)
Answer: With LiFePO4 cells it is possible to charge with non-impulsive DC current. There is no study or a test report known to us that would show any advantages of impulse current charging against the standard flat current charging. Based on comments from LFP cells suppliers, as far as possible the cells should be charged with continuous (non-impulsive) DC currents.
FAQ: Do we need to install a temperature sensor to monitor the charging of the cells?
Answer: Certainly it is wise to install temperature sensors as secondary protection during the cells operation. Each cell should have its own sensor. During the standard operation all cells should have identical temperature corresponding to the temperature of the surrounding environment. The LFP cells do now get significantly warm during regular operation (standard charge/discharge at 0.5C and less).
If the temperature sensors show a temperature difference of one or more cells (even if the difference is just a few degrees), it is suggested to inspect the operation of such cells to find out the reason for the temperature increase. It is to better to locate a possible problem before the cells may get damaged for some reason.
