Method for estimating and displaying the time it will take to charge an electric battery from an initial level of energy to a target level of energy, the actual capacity of the battery being made up of a useful capacity and a reserve capacity, a useful charging range being included within an actual charging range between a minimum and a maximum level of energy, the target level of energy corresponding to the maximum level of energy, characterized in that the method comprises the following steps: - at the start of a charging phase, a step of estimating and displaying a total charging time ( t _ EHC_est) required to reach the target level of energy, - a step of estimating and displaying an intuitive remaining charging time ( t _ rest _ ch _ parf) required to reach the target level, said intuitive time initially being equal to the total charging time ( t _ EHC_est) then being decremented by one unit of time for each unit of time which passes; - a step of estimating an intuitive state of charge ( SOC_parf) and an intuitive energy level ( En_parf), the intuitive state of charge initially being equal to the state of charge corresponding to the initial level of energy then being incremented, for each unit of time which passes, by an amount equal to the difference between the levels of charge corresponding to the target level of charge and the initial level of charge divided by the total charging time, and the intuitive energy level (En_parf) being the minimum value among an actual energy level reached and the energy level corresponding to the intuitive state of charge calculated in the following way: En_parf (t) = min(En_reelle(t), (SOC_parf(t)/100) x capa_utile), where En_reelle is the actual energy of the battery, SOC_parf is the intuitive state of charge and capa_utile is the useful capacity that is able to be used by the user, - at the end of the charging phase, a step of readjusting the useful charging range within the actual charging range by setting the minimum level of energy of the useful charging range to the actual energy level (En_reelle(tf)) reached at the end of the charging phase, from which the value of the intuitive energy level (En_parf(tf)) is subtracted at the end of the charging phase. - at the start of a charging phase, a step of estimating and displaying a total charging time ( t _ EHC_est) required to reach the target level of energy, - a step of estimating and displaying an intuitive remaining charging time ( t _ rest _ ch _ parf) required to reach the target level, said intuitive time initially being equal to the total charging time ( t _ EHC_est) then being decremented by one unit of time for each unit of time which passes; - a step of estimating an intuitive state of charge ( SOC_parf) and an intuitive energy level ( En_parf), the intuitive state of charge initially being equal to the state of charge corresponding to the initial level of energy then being incremented, for each unit of time which passes, by an amount equal to the difference between the levels of charge corresponding to the target level of charge and the initial level of charge divided by the total charging time, and the intuitive energy level (En_parf) being the minimum value among an actual energy level reached and the energy level corresponding to the intuitive state of charge calculated in the following way: En_parf (t) = min(En_reelle(t), (SOC_parf(t)/100) x capa_utile), where En_reelle is the actual energy of the battery, SOC_parf is the intuitive state of charge and capa_utile is the useful capacity that is able to be used by the user, - at the end of the charging phase, a step of readjusting the useful charging range within the actual charging range by setting the minimum level of energy of the useful charging range to the actual energy level (En_reelle(tf)) reached at the end of the charging phase, from which the value of the intuitive energy level (En_parf(tf)) is subtracted at the end of the charging phase.
