Can car charging t-level tri-levels be boosted and bucked?

Transmission lines are resistive, the longer the line the greater the resistance. In order to reduce the line loss, and the loss of power = line resistance * the square of the value of the current flowing, only to reduce the value of the current flowing, in order to reduce the line loss, the power of transmission = voltage * current, increase the voltage, the current is naturally smaller. So, first raise the voltage, to the place where the power is used, and then lower the voltage.
