Advantages of High Voltage in Electric Vehicle Designs
Watt''s Law P (Power) = V (Voltage) x I (Current) This relationship points the way toward significant efficiency gains. A key concept in electronics is that higher current translates directly to increased heat. The primary source of heat here is the copper losses, where high current causes heat in the conductors through a resistive load.

Why do higher voltage batteries need lower KV motors?
It''s not that high voltage batteries need to be paired up with low kV motors. There''s nothing inherently wrong with this configuration, it''ll just result in the motor''s shaft spinning an ungodly rate. This is because the rotation rate is (theoretically, and only when no load is applied to the motor shaft) equal to kV * voltage. ...
