BACKGROUND OF THE INVENTION

The use of electric vehicles for private users is currently being extended. Apart from the known advantages of these vehicles, the problem of their recharging is raised, which although it may well be using the domestic network, it raises some technical details that make its use uncomfortable, since the recharging of an electric vehicle implies several hours of connection the expense and occupation of the domestic electricity supply that entails.

On the other hand, the widespread use of wireless devices, especially smart phones (smartphones) and tablets (tablets), is known at the present time. Such is its popularity that any modern application must be managed and reviewed on these devices so that it has a certain acceptance in the market.

There are solutions to manage and control the charge of electric vehicles, which consist of a direct communication with the vehicle. These solutions are focused on giving security to the loading process, and the more features they include are more expensive. The major functionalities are focused on providing external load management system, but do not handle vehicle information. There are other solutions that allow you to communicate with the vehicle, but they are limited in compatibility, they are physically in the vehicle. Thus, there is no known system equipped with universality in an intermediate device, external to the vehicle, which manages communication with the vehicle, which communicates with the user and with a universal external management system independent of the vehicle.

WO2011109460 discloses a system for charging control of an electric vehicle in which a mobile device of the portable type is used to reserve a charging station at a given time, useful for charging stations public or shared, including the possibility of payment; When the vehicle approaches the loading station, a more portable mobile device, such as a mobile telephone, verifies its availability with the loading position. The loading post sends a certificate with information about the vehicle load. This invention focuses on managing the reservation of cargo posts, but does not establish a management of the load parameters from the mobile device with information on data coming from the vehicle, nor can it be used in a domestic environment.

Therefore, there is a need for a simple and economical system that allows the control and management of the charging parameters of an electric vehicle that manages data from the load, the vehicle, the user and the central management of the system itself.

DESCRIPTION OF THE INVENTION

The present invention is established and characterized in the independent claims, while the dependent claims describe other features thereof.

The object of the present invention is a simple and economical system that allows the control and management of the charging parameters of an electric vehicle using an external device for communication with the elements of the system and with direct communication with the vehicle. The technical problem to solve is to constitute a system with the adequate elements to achieve the mentioned object.

In view of the foregoing, the present invention relates to a system for control and management of electric vehicle charging, that is, that the load parameters such as the duration of the charge, the connection time can be handled , the moment of disconnection, the choice of the most economical tariff period, vehicle variables such as load level, calendar data of a reservation system or central coordination, etc.
