System and methods for smart charging techniques

a charging system and smart charging technology, applied in the direction of memory systems, electric energy management, electric devices, etc., can solve the problems of simple timer systems merely delaying charging to a fixed off-peak time, and purely schedule-based systems cannot address unpredictable operational demands, so as to reduce the congestion of the electric distribution network, reduce the cost of electricity, and reduce the effect of greenhouse gas emissions

Benefits of technology

The patent text describes a centrally controlled smart charging system for electric vehicles that can reduce costs, reduce congestion, and reduce greenhouse gas emissions. The system requires a server to coordinate the charging activities of a large number of vehicles distributed over a wide area. The server can produce substantial benefits even when direct low-latency communications links between the server and each device or vehicle are precluded. The method includes periodically transmitting a charging schedule from the server to electric resources, receiving the schedule, and replacing or overriding the prior charging schedule with the received schedule. The server can also manage the total power level for the electric resources based on the determined power levels of the controlled and uncontrolled resources, adjusting the energy price for prices-to-devices enabled electric resources, and managing the charging behavior of the prices-to-devices enabled electric resource based on the adjusted energy price.

Problems solved by technology

Simple timer systems merely delay charging to a fixed off-peak time.
Purely schedule-based system cannot address unpredictable operational demands.

Embodiment Construction

[0030]Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

[0031]Overview

[0032]Described herein is a power aggregation system for distributed electric resources, and associated methods. In one implementation, a system communicates over the Internet and / or some other public or private networks with numerous individual electric resources connected to a power grid (hereinafter, “grid”). By communicating, the system can dynamically aggregate these electric resources to provide power services to grid operators (e.g. utilities, Independent System Operators (ISO), etc).

[0033]“Power services” as used herein, refers to energy delivery as well as other ancillary services including demand response, regulation, spinning reserves, non-spinning reserves, energy imbalance, reactive power, and similar products.

[0034]“Aggregation” as used herein refers to the ability to control power flows into and out of a s...

Abstract

A system and methods that enables smart charging techniques. A smart charging method may include periodically updated schedules. In addition, a smart charging method may include schedules with overrides. Further, a smart charging may involve a method for local load management in the presence of uncontrolled loads. A smart charging method for managing electric resources may also provide direct control over prices-to-devices enabled devices.
