System and method for charging capacitors of an electric vehicle

An electric vehicle 10 is provided having an electric generator 36 and a motor 34. A voltage bus including a DC link 54 is configured to provide generated electrical energy to the motor 34. A controller 64 may estimate the charging current to a capacitor 56 of the voltage bus based on the current commanded from the generator 36 and the voltage measured across the capacitor 56. The controller 64 may adjust the charging rate of the capacitor 56 based on the estimated charging current.
