1. A vehicle comprising:
an electric motor;
a variable displacement hydraulic pump having a swash plate;
driven traction members;
a transmission operably coupling the electric motor to the driven traction members and to the hydraulic pump;
a hydraulic pressure consumer fluidly coupled to an output of the hydraulic pump;
a battery to receive energy produced by the electric motor during braking of the driven traction members by the electric motor;
a controller configured to adjust an angle of the swash plate in response to a sensed state of the battery and braking of the driven traction members.
 
14. A vehicle braking method comprising:
determine braking by a vehicle;
determine a battery state of a battery used to propel the vehicle;
in response to the battery state satisfying a predetermined threshold, adjusting a swashplate angle of a variable displacement hydraulic pump to a braking angle; and
in response to the battery state satisfying the predetermined threshold, directing flow from the variable displacement hydraulic pump to a compensator/relief.
