An electric vehicle charging station that is installed in a residence is coupled with a main circuit breaker in an electrical service panel. The charging station includes a charging point connection that couples an electric vehicle to a set of service drop power lines that provide electricity from a power grid to the residence; a current control device coupled to control the amount of electric current that can be drawn from the set of service drop power lines by an the electric vehicle through the charging point connection; a receiver to receive energy readings from one or more current monitors that indicate an amount of current is being drawn from the set of service drop power lines; and a set of control modules to cause the current control device to control the amount of current that can be drawn by the electric vehicle through the charging point connection based on the received energy readings to avoid tripping the main circuit breaker.

Method and apparatus for electric vehicle charging station load management in a residence

Dynamic allocation of power modules for charging electric vehicles is described herein. A power cabinet includes multiple power modules that each are capable of supplying an amount of power to a dispenser. Multiple dispensers are coupled with the same power cabinet. A first power bus couples a first dispenser and switchably connects the power modules to the first dispenser; and a second power bus couples a second dispenser and switchably connects the power modules to the second dispenser. The power cabinet includes a control unit that is configured to cause the power modules to switchably connect and disconnect from the first power bus and the second power bus to dynamically allocate the power modules between the first dispenser and the second dispenser.

Dynamic allocation of power modules for charging electric vehicles

A total amount of current drawn through a first charging equipment and a second charging equipment that wired on a same electrical circuit is limited to not exceed a maximum amount of electric current supported by the electrical circuit to prevent the electrical circuit from being overloaded, where limiting includes communicating a first current limit to a first electric vehicle connected to the first charging equipment to cause the first electric vehicle to limit its current draw to not exceed the first current limit, and communicating a second current limit to a second electric vehicle connected to the second charging equipment to cause the second electric vehicle to limit its current draw to not exceed the second current limit, where a sum of current being drawn at the first current limit and the second current limit does not exceed the maximum amount of electric current supported by the electrical circuit.

Managing electric current allocation between charging equipment for charging electric vehicles

The concept of smart home is an emerging issue to the modern technology dependent society Remote control technologies are widely used to control household electronic appliances without walking up to them Controlling household appliances through computer can also be a possible solution However, it cannot fulfil the current demand which is to control them from remote places The advantages of cellular communications like GSM technology is a potential solution for such remote controlling activities GSM-SMS technology can be used to control household appliances from remote places With these hypotheses, three different approaches have been proposed and implemented in this paper Firstly, household appliances are controlled by server mobile which acts as remote control Secondly, GSM-SMS messaging technology is used to control them from remote places and finally, to provide a multiple agents environment This paper discusses about the design and implementation issues of such smart home

The Implementation of Controlled Humanoid Robot with Android

This system offers a new approach to control home appliances from a remote terminal, with an option from a local server, using the Internet and radio connection This system is accomplished by personal computers, interface cards, radio transmitters and receivers, microprocessors, ac phase control circuits, along with window-type software and microprocessor control software The system is designed to control home appliances' on/off, to regulate their output power, and to set their usage timing The prototype of this system was tested and responded successfully, which verifies the feasibility of this system's theory and concept
