When the weather is hot, the electric car starts slowly and runs fast at night.

The tire pressure is too low because of the motor.

The air pressure of a normal electric vehicle is between 365,438+00 and 380kpa. Although the air pressure of a hot electric car can be slightly lower, if the air pressure is too low, the friction of the electric car will increase, the battery loss will accelerate, the cruising range will be reduced, and the electric car will not run far.

At present, some illegal manufacturers are using some refurbished motors as new motors, but these motors often have large power loss and low matching degree with control, which will accelerate the power loss during use, which is also a big reason why electric vehicles can't run far. Some motors may rust in summer water, which will strain the battery and reduce the battery life.
