METHOD FOR THE MANAGEMENT OF THE ELECTRICAL CURRENT SUPPLY IN A MOTOR VEHICLE |
摘要 |
This disclosure relates to a method for the management of the electrical current supply in a motor vehicle having a combustion engine, wherein the charge state of a battery is detected and characterized as a discrete variable that indicates whether the prevailing charge state is below or above a calibrated threshold value. If the discrete variable indicates that the prevailing charge state is below the calibrated threshold value, the battery is charged using a relatively high voltage over a predetermined time period in such a manner that all cells of the battery are charged. If the discrete variable indicates that the prevailing charge state is above the calibrated threshold value, different temperature-dependent voltage set points of an electric generator in the vehicle are set in dependence upon a prevailing energy conversion efficiency level of the drivetrain that is detected and characterized as a further discrete variable. |

1. A method for managing current supply in a vehicle comprising:
in response to a discrete variable indicating that a charge state of a battery is less than a calibrated threshold value, charging the battery using a voltage setpoint over a predetermined time period such that cells of the battery are charged to a target; and in response to the discrete variable indicating that the charge state is greater than the calibrated threshold value, setting a voltage setpoint for an electric generator based on a parameter indicative of drivetrain efficiency and a parameter indicative of temperature of the battery. |
