What is the wattage of a motor compatible with both 60V and 72V?

These two types of motors are not compatible. Differences in range: The biggest difference between 60V and 72V electric vehicles is the range. A 72V electric vehicle has a slightly longer range than a 60V one because the 72V battery has a larger capacity. Differences in capacity: Assuming a standard rated current of 20A, according to the electrical power formula P=U×I, we get: 72Vx20A=1440W, 60Vx20A=1220W. Here, P represents the total power (battery capacity), U is the rated voltage, and I is the rated current. This means that an electric vehicle with a rated voltage of 70V has a capacity 220W higher than one with a rated voltage of 60V. Differences in rated voltage: One has a rated voltage of 70V, while the other has a rated voltage of 60V, designed to match different motors. Differences in speed: According to the electrical power formula P=U×I, higher voltage results in greater power output, leading to faster speeds for the electric vehicle. Differences in mileage: Based on Joule's Law Q=I²Rt, current flowing through a conductor generates heat, meaning higher current results in more heat and greater energy waste. Under the same power conditions, higher voltage leads to lower current and higher efficiency.
