Abstract

The present invention relates to a vehicle battery power transfer limit management system and method. A vehicle includes a powertrain and a traction battery, wherein the powertrain includes an electric machine. The vehicle also includes at least one controller configured to cause the electric machine to absorb torque during a transmission shift event. Absorbing the torque causes the battery to be charged with the current produced by the electric machine according to a predetermined power transfer schedule that defines a charge limit. The controller is also configured to allow the current to exceed the charging limit for a predetermined duration under certain conditions.

Description

technical field [0001] The present disclosure relates to power flow management of high voltage power sources for vehicles. Background technique [0002] Batteries used in electric or hybrid electric vehicles, like any battery, have limited power transfer capabilities. Power delivery beyond certain limits may be undesirable. Limiting charge and discharge currents to less than the full battery power delivery capability prolongs battery life. Appropriate limits may also be affected by vehicle operating conditions. The battery power delivery limit is also operable to constrain vehicle performance requiring higher levels of power delivery. Contents of the invention [0003] In at least one embodiment, a vehicle includes a drivetrain and a traction battery, wherein the drivetrain includes an electric machine. The vehicle also includes at least one controller configured to cause the electric machine to absorb torque during a transmission shift event. The absorbing torque cau...
