4 Weeks remaining: Small Scale Prototype
Wayside Power Small Scale Prototype: Update 4 Weeks remaining Issues this week: Maxwell has still not gotten back to us, so we have begun to look for cheaper alternatives If we create a supercap bank made up with many 2.7V cells in combination of series and parallel, we will be able to save money. This does cause the charging time to increase to about 4 minuets, up from about 45 seconds, as each cell can only handle about 30A of current vs 2000A with the other more expensive modules. We will have to solder all of these together. We will have to create a casing to hold and easily assemble, dissemble. We can use SAB MOSFETS to balance our series stack and prevent overcharging instead of trying to match a mosfet of the shelf with our ucap modules, this is a good thing! These are specifically designed to be a low cost and low power usage solution to balancing supercaps in series. https://www.digikey.my/en/videos/a/advanced-line...
Full-Scale Wayside Team: Great data collection and specifications. Please include some written paragraphs, commenting on what all of this data means for your project, and what you intend on using this data for. How will it affect how you design your wayside system? Some of the data is obvious, while other parts of the data is not.
