1. An electric vehicle, comprising:
- a frame;
a plurality of ground engaging members supporting the frame;
an electric motor supported by the frame and operatively coupled to at least one of the plurality of ground engaging members to propel the vehicle;
a battery supply supported by the frame, the battery supply being operatively coupled to the electric motor;
a plurality of chargers supported by the frame operatively coupled to the battery supply to charge the battery supply, the plurality of chargers being coupled to the battery supply in parallel;
an electronic controller operatively coupled to the electric motor to control operation of the electric motor;
an operator area supported by the frame, the operator area including seating and operator controls, at least a first operator control providing an input to the electronic controller regarding a desired speed of the electric vehicle, wherein the plurality of chargers are positioned forward of a front plane of the seating and the electric motor is positioned rearward of the front plane of the seating, wherein the battery supply is positioned generally under the seating;
a first differential supported by the frame rearward of the front plane of the seating and operatively coupled to at least a first ground engaging member which is rearward of the front plane of the seating, the electric motor being operatively coupled to the first differential;
a second differential supported by the frame forward of the front plane of the seating and operatively coupled to at least a second ground engaging member which is forward of the front plane of the seating the electric motor being operatively coupled to the second differential; and
