Discussion on the electrical basis of EV charging

Of course, the definition of voltage: voltage is also known as potential difference or potential difference, is a physical quantity that measures the energy difference generated by the unit charge in the electrostatic field due to the different potential. Voltage is represented by the letter U, the unit is volts, abbreviated as volts, and is represented by the letter V. ==1 Dc and AC circuit basics: Definition of direct current: direct current is referred to as DC, also known as "constant current", constant current is a kind of direct current, is the size and direction of the same direct current. The magnitude of the current (high voltage) and the positive and negative electrodes do not change with time (relative range). ==2 The definition of alternating current: Alternating current is referred to as AC, alternating current is also called "alternating current", referred to as "AC". Generally refers to the size and direction of the periodic change of voltage or current at any time. Its most basic form is sinusoidal current. ==3 Alternating current is widely used for power transmission because it is more efficient than direct current under previous technical conditions. The easy rise and fall of AC voltage is just suitable for high-voltage transmission. The use of a simple booster transformer can increase the alternating current to several thousand to several hundred thousand volts, so that the power loss on the wire is minimal. In the city, step-down transformers are generally used to reduce the voltage to tens of thousands to several thousand volts to ensure safety. ==4 Visit our blog to learn more about EV charge: https://www.omgevcable.com/
