Abstract (en)
[origin: WO2022254107A1] The present invention relates to a method for recharging a traction battery (3) for an electric vehicle (1) that can be recharged by means of a recharging terminal (7) in which a predetermined recharge mode is configured that determines the setpoint recharging current for governing the terminal (7), comprising governing a first recharging phase controlled by a first current setpoint CR1 as long as the state of charge of the battery (3) is lower than a predetermined state of charge threshold (S1), and governing a second recharging phase when the state of charge is higher than said state of charge threshold (S1), characterized in that the control (23, 24) of the recharging current, during the second recharging phase, is governed by the first current setpoint CR1 if the environment temperature (T) is lower than said temperature threshold (T1), and when the environment temperature (T) is higher than or equal to said temperature threshold (T1), the control (24) of the recharging current is governed by a second recharging current setpoint CR2 having a value which is a function of a predetermined reduction coefficient k according to the following equation: CR2 = k*CR1, where k is between 0.2 and 0.8.
