US 2025/0050863 A1 · METHOD FOR DETERMINING AND RESETTING THE STATE OF CHARGE OF THE BATTERIES OF A HYBRID VEHICLE

Abstract

A method is for determining and resetting the state of charge of at least one battery of a hybrid vehicle including a first battery, a second battery and a heat engine. The method includes, during a standby phase of the vehicle, a first step of charging the first battery via the second battery, during which: (i) the first battery is charged; (ii) the value of its voltage is measured; (iii) the value of the voltage of the first battery is compared with a threshold voltage value corresponding to a maximum state of charge of the first battery; and (iv) when the threshold voltage value is reached, stopping the charging of the first battery, determining that it is in a maximum state of charge and setting a value of its state of charge to maximum state of charge, and otherwise continuing to charge.

A method for determining and recalibrating a state of charge of at least one battery of a hybrid vehicle, the vehicle comprising a first battery, a second battery, and a combustion engine, said method comprising:

charging, during a vehicle standby phase, the first battery via the second battery, the charging including:
(i) charging the first battery,
(ii) measuring a value of a voltage of the first battery,
(iii) comparing the value of the measured voltage with a first threshold voltage value corresponding to a maximum state of charge of the first battery,
(iv) when the value of the measured voltage reaches said first threshold voltage value, stopping the charging of the first battery, determining that the first battery is in the maximum state of charge, and setting a value of a state of charge of the first battery to the value of the maximum state of charge, and when the value of the measured voltage has not reached said first threshold voltage value, continuing the charging of the first battery.
