Charger for electric vehicle

Abstract

The invention relates to a charger for an electric vehicle, belonging to a charger and comprises a charger body, a charging wire and a plug arranged on the charger body and connected with a power supply, wherein the charger body is internally provided with a winding transformer, a plurality of taps are extracted from the winding transformer, each tap is conducted with a circuit by the rotation of a knob arranged on a shell of the charger body, and the charger body is internally provided with an adjustable resistor and a resistor knob is arranged on the shell of the charger shell for realizing transformation of output current; and a plug hole is arranged on the charger body, the plug hole is matched with a charger plug hole at one end of the charging wire, and the other end of the charging wire is connected with a storage battery. The invention has the advantages that: a universal charger brings great convenience for the production and the management of a manufacturer, the manufacturer only needs to produce the same mould shell to be assembled with electronic components, and simultaneously produce various types of charging wires; and the voltage and the current are adjustable, therefore, the use range is enlarged.

Description

technical field [0001] The invention relates to a charger, in particular to a universal electric vehicle charger suitable for various types of electric vehicles. Background technique [0002] With the popularization of electric vehicles, it has become an indispensable means of transportation in people's daily life, but 1) the battery charging sockets of various electric vehicle manufacturers are different, there are positive polarity and reverse polarity, and the shape of the jack also has different There are round holes and square holes; 2) At the same time, there are differences in the capacitance and voltage of the battery. The existence of the above two situations shows that each different type of storage battery requires a different type of charger, which undoubtedly brings troubles to charger manufacturers, sellers, and consumers at the same time. 1) Due to the diversity of charger types, in order to To distinguish them, different types of chargers need to be marked, ...

AI Technical Summary

Problems solved by technology

The existence of the above two situations shows that each different type of storage battery requires a different type of charger, which undoubtedly brings troubles to charger manufacturers, sellers, and consumers at the same time. 1) Due to the diversity of charger types, in order to To distinguish them, different types of chargers need to be marked, which increases the production cost; 2) Sellers need to import multiple types of chargers, which will easily cause confusion during transportation and sales, and increase management troubles ; 3) Some families now have many different types of electric vehicles, so they must be equipped with multiple types of chargers. Users are prone to purchase mistakes during the purchase process, either cannot be charged effectively, or cause damage to the battery, which is very difficult to use. inconvenient
