Evolution of Project

The Holy Grail:

Click to view the Long Story.


Where the Short Story - Long Story Merge:
Recently a 'what-iffing' proposal to retrofit an existing diesel powered vehicle for eventual title transfer to my grandsons 'hit' the Lithium battery obstacle. It was roughly two-thirds of the total project cost as well as roughly a twenty percent addition in vehicle weight and a corresponding projected drop in vehicle performance/range.

Summary:
Facing this obstacle, the search for the Holy Grail started. The search evolved a solution incorporating proven basics established in the 1920's -1930's and minor 'tweaking' of modern electrical materials. Initial design work has reached a threshold where it is time to reach-out for additional resources, engage in intellectual property protection, fund prototyping, and discuss licensing arrangements.

Working Assumptions:

The working assumptions are:

Reference:

This project is an excellent example of standing upon giants shoulder so the you can see the future. The table given below is but a partial list on the giants that played a role in the project's maturity.

The references are split into a short list of "primary" references given directly below and into the Supporting Reference section table given at the bottom of the page. The reader may also come across images and spreadsheet references. A complete set of project notes provide a "grubbing trail" that was followed to reach a level of knowledge required to carry this project to its current status. That set of development notes is available upon request.

https://www.youtube.com/watch?v=lEQoKTjsRMo This URL is truly where the Quest for the Holy Gail started. The URL provided is the first of a youtube series covering conversion of exisiting street vehicle to electric. This is a 'fine detail' series which is targetted at the DIY-Plus project. It contains one of the best discussion of the impact of the 'Battery Pack' on the design of EV's. Within the series it introduces motors, controllers, coupleres, etc. Their web page is https://ev4unow.com/. A collection of salient images from the various presentations was been and transposed to 'numbers' in a PDF printout of a spreadsheet used for 'what-iffing'. The spreadsheet helped to focus a 'ballpark' dollar numbers of the original 'personal objective'.
