Abstract: The present document describes an intelligent charging system in direct current for electric vehicle batteries. The developed system, based on the concept of modularity, allows an intelligent, simultaneous and sequential charging of different vehicle models available on the market. Its modularity makes it possible to charge electric vehicle batteries at maximum powers that are a multiple of a given unit power, for example 50 kW, the only limitation for the total power of the charging system is the availability of the electrical power supply on which it depends, whether it’s alternating current or direct current, coming from the electrical grid or other sources such as: local generation, energy storage banks, electrical traction grids, among others.
