Claim Text:
1. A motor vehicle with electric or hybrid propulsion comprising: a rechargeable electric accumulation battery; a braking system allowing recovery of energy; the battery being rechargeable during braking phases and during charging phases during which the vehicle is stationary under control of a power supply system comprising means for determining a maximum allowable power for the battery, the means for determining the maximum allowable power for the battery comprises a first mapping including a first maximum power on the basis of temperature and state of charge of the battery and a second mapping including a second maximum power on the basis of the temperature and state of charge of the battery, the first maximum power being greater than the second maximum power, the first mapping comprising first maximum power values corresponding to a braking phase and the second mapping comprising second maximum power values corresponding to a charging phase of the battery; and means for calculating the maximum allowable power for the battery, the means configured to calculate the sum of the first maximum power affected by a first coefficient α(t) between 0 and 1 and of the second maximum power affected by a second coefficient equal to 1−α(t).
