Event Report

We did it: another successful EV event despite CoVid restrictions.  

This time we organized a local car rally with 7 people in a completely distanced manner (our own cars) and then used data and footage from this rally to run a global Zoom event on Earth Day to share the learnings more broadly.

Much to our surprise, we attracted an international audience, and not just from North America but also including Germany.

The event I think successfully explained how to run a local car rally to evaluate the regenerative braking efficiency of any EV (or Plug-In Hybrid).  This is an enormously powerful and easy way to demonstrate one of the best reasons to own an EV, and the reason they are such an efficient means of getting around and transporting things.

Thanks to all who participated and I hope this starts or continues a conversation on how EVs are changing our lives.

Event Description

 

A popular local EV rally involves an EV hill climb up a local ski mountain with EV owners each driving their own car while measuring and then sharing their energy usage.  This event will be an on-line "Zoom" meetup that will explain just such a rally.

The real event is a four-stage rally, and data at the end of each stage are added to a spreadsheet that calculates the efficiency of each car in recovering the potential energy gained from the altitude change.  How this is done may not be intuitive, but we will explain the logic, the formulae, and the results for several different EVs.  We have photos to share, plus the master spreadsheet, and we hope to teach everyone how to organize their own EV efficiency rally.  

It is also important to note that our findings apply equally to braking on flat ground, because regeneration can recapture kinetic as well as potential energy.  High school physics proves its worth!

We will also unveil an exciting finding for the bravest EV drivers among us.  Join us to find out what that terrifying eureka moment was all about.
