KWHR Meter Project


Summary

This project, the KWHR Meter Project, is a project to design and construct a device capable of providing feedback on the amount of electrical energy used by a house or small building and also limiting usage based on a set energy quota. The KWHR Meter Project a research project with the strong possibility of a concrete application. It was requested by Matt Walsh, former Dokimoi Ergatai (Collaboratory) member and Energy group advisor, who is now serving as a missionary in Burkina Faso and has need for such a device. The concept is designed with a limited energy source in mind, such as a solar energy source. More information can be found in the project proposal article.

Purpose statement

The purpose of this project is to design and implement a reliable, manufacturable device to measure, display, and limit kilowatt-hour usage of a home or AC sub-system with the goal of energy awareness, equitable energy sharing, and energy conservation.

Goals

(As copied from the project proposal article)

  1. Design and construct a proof of concept digital KWHR meter and controller which is able to display energy usage and disconnect the energy source in the case of over-usage, as specified by the requirements in the specifications section below. Target date February 2010.
  2. Design and construct a first generation KWHR meter based on the proof-of-concept device, which shall include all functionality of the proof-of-concept while also conforming to safety and environmental requirements as summarized below. Target date May 2010.
  3. Coordinate with Matt Walsh in Burkina Faso to conduct a complete, in-field functionality test and document the test with a complete report of successful and failed functionality, recommended improvements, and other relevant information. Target date June 2010.
  4. Perform a manufacturability analysis of the first generation device and document with rationale any necessary design changes for cost-optimization or ease of manufacturing. Target date December 2010.
  5. Design and construct a prototype of a second generation device incorporating the results of the in-field test and manufacturability analysis conducted using the first generation device. Target date May 2011.
  6. Construct 5-10 second generation devices and coordinate with Matt Walsh to implement them in Burkina Faso in conjunction with the solar energy system at the mission station in Mahadaga, Burkina Faso. Conduct a long-term use test of the devices, documenting any further design flaws or desired changes. Target date December 2011.
  7. Write user's and installer's manuals for the second generation device, incorporating feedback from Matt Walsh and other testers. Target date May 2012.

History

This project is starting up in the Fall of 2009. It was prompted by a request from Matt Walsh in August 2007. In January 2012, three meters were installed in Burkina Faso. Feedback from the use of these meters aided in the final Phase I model, five of which will be sent to Burkina Faso in January 2013.
