Zusammenfassung:	The present disclosure relates to a method, apparatus, medium and device for determining a voltage inflection point of a cell core in a LFP battery. The method includes: charging the LFP battery with a first current value and monitoring the State of charge (SOC) of the LFP battery, the first current value being greater than a predetermined threshold of current; if the SOC of the LFP battery is outside a predetermined detection range, controlling and charging the LFP battery with the first current value; if the SOC of the LFP battery is within the detection range, controlling and charging the LFP battery with a second current value, the second current value being less than the predetermined threshold of current; and detecting the voltage inflection point of various cell cores in the LFP battery according to parameter information of the various cell cores in the LFP battery in the process of charging where the SOC of the LFP battery is within the detection range.
