Electric vehicle with an electric powerpack arrangement

A straddle seat electric vehicle comprising:

• a frame;
• a straddle seat supported by the frame;
• at least one ground-engaging member operatively connected to the frame;
• an electric motor being operatively connected to the at least one ground-engaging member for driving the at least one ground-engaging member;
• an electric powerpack operatively connected to the electric motor, the powerpack comprising:
• a battery pack comprising:
• a battery housing including:
• a housing body,
• a cooling channel defined in the housing body, the cooling channel extending generally vertically through a center portion of the housing body,
• a first cover selectively connected to the housing body, and
• a second cover selectively connected to the housing body;
• a first plurality of cylindrical battery cells disposed in a first chamber defined by the battery housing laterally between the cooling channel and the first cover, each battery cell of the first plurality of battery cells extending generally orthogonally to the cooling channel and the first cover;
• at least one first current collector disposed laterally between the first cover and the first plurality of battery cells, the at least one first current collector being electrically connected to the first plurality of battery cells,
• the first cover enclosing the at least one first current collector and outer ends of the battery cells of the first plurality of battery cells, the first cover being electrically insulated from the at least one first current collector;
• a second plurality of cylindrical battery cells disposed in a second chamber defined by the battery housing laterally between the cooling channel and the second cover, each battery cell of the second plurality of battery cells extending generally orthogonally to the cooling channel and the second cover;
• and
• at least one second current collector disposed laterally between the second cover and the second plurality of battery cells, the at least one second current collector being electrically connected to the second plurality of battery cells,
• the second cover enclosing the at least one second current collector and outer ends of the battery cells of the second plurality of battery cells, the second cover being electrically insulated from the at least one second current collector.
