【 摘 要 】

The paper presents the results of testing the LT-LFP.300.11.01 Li-Ion cells under different conditions of charge by stable and pulse width modulation current. The shown study proves the possibility of approaching the diagnosis of battery cell before multi stage charging cycles. This approach helps to determine the real cell state of charge, which is important for the charger in turn for the determination of the initial current value at the very first stage of charge. Using the trickle charge algorithm, each battery cell may be charged individually in accordance with its initial state of charge, chemical condition and temperature. This approach should use a special charger acceptable for multi-cell charge or diagnosis of individual cells with a balancing apparatus. The same approach could be used for battery restoration.
