A method of charging a battery of electrochemical accumulators, particularly a lithium battery, by means of a power source, comprising: a step of charging the battery by connection to the power source for a determined time interval having a duration longer than or equal to 1 minute; at the end of said time interval, a first step of measuring a voltage (Vbatt) of the battery in charge mode; a first test enabling to detect whether the measured voltage (Vbatt) of the battery in charge mode during the first measurement step is equal to or greater than a target voltage which is equal to an open-circuit voltage of the battery at a desired target state of charge (SOCO); if the first test is negative, resuming the charge process from the charge step; if the first test is positive, a pause step, having a predefined duration (dpause), during which the battery is disconnected from the power source and in the idle state; a second step of measuring the voltage (Vbatt) of the battery at the end of the pause; a second test comprising verifying whether the voltage (Vbatt) of the battery measured at the end of the pause meets an end-of-charge criterion relative to the target voltage; if the second test is positive, stopping the charge process; and if the second test (E7; E19) is negative, resuming the charge process from the charge step, wherein the pause step comprises: a first pause, followed by a step of measuring the battery voltage (Vbatt) and by an intermediate test step to verify whether the voltage measured after the first pause is greater than or equal to the target voltage, and a second pause implemented only if the intermediate test is positive, and wherein the duration of the first pause is shorter than the duration of the second pause. a step of charging the battery by connection to the power source for a determined time interval having a duration longer than or equal to 1 minute; at the end of said time interval, a first step of measuring a voltage (Vbatt) of the battery in charge mode; a first test enabling to detect whether the measured voltage (Vbatt) of the battery in charge mode during the first measurement step is equal to or greater than a target voltage which is equal to an open-circuit voltage of the battery at a desired target state of charge (SOCO); if the first test is negative, resuming the charge process from the charge step; if the first test is positive, a pause step, having a predefined duration (dpause), during which the battery is disconnected from the power source and in the idle state; a second step of measuring the voltage (Vbatt) of the battery at the end of the pause; a second test comprising verifying whether the voltage (Vbatt) of the battery measured at the end of the pause meets an end-of-charge criterion relative to the target voltage; if the second test is positive, stopping the charge process; and if the second test (E7; E19) is negative, resuming the charge process from the charge step, wherein the pause step comprises: a first pause, followed by a step of measuring the battery voltage (Vbatt) and by an intermediate test step to verify whether the voltage measured after the first pause is greater than or equal to the target voltage, and a second pause implemented only if the intermediate test is positive, and wherein the duration of the first pause is shorter than the duration of the second pause. a first pause, followed by a step of measuring the battery voltage (Vbatt) and by an intermediate test step to verify whether the voltage measured after the first pause is greater than or equal to the target voltage, and a second pause implemented only if the intermediate test is positive, and wherein the duration of the first pause is shorter than the duration of the second pause.
