Welcome and thanks for your interest in volunteering for the next level of Recurrent battery diagnostics!
Recurrent won a National Science Foundation grant to enhance and validate our machine learning models. With this new funding, we will be sending volunteers aOBDII plug-in diagnostic device to use for a few weeks so we can collect data we aren’t usually able to get, such as efficiency, AC/DC charging diagnostics, and information to estimate usable battery capacity.
This is a pilot program so please reach out to us with any questions that this page doesn’t cover.
If you think this sounds cool (or you just like science), please indicate interest by filling out this form with your name, email, vehicle model, and zip code. This is not a commitment and we will contact volunteers in the next few weeks with more details.
What is the big deal?
Recurrent has been awarded a National Science Foundation Small Business Innovation Research (SBIR) grant worth $256k to investigate and validate our machine learning model using hands-on diagnostics. There are a few data points that we are currently unable to get from our automatic data collection, including efficiency, AC/DC charging patterns, and other information to estimate usable battery capacity. This program will allow us to collect this information for select drivers and use it to make our predictions and models better for all drivers.
What will be involved
We are currently recruiting volunteers and hammering out the details for an August launch. Details or specifics may change, but here are a few things we know for sure.
This pilot study will be at no cost to you. We will send you everything you need, including instructions and a return shipping envelope.
The device used in this program will be a OBDII plug in diagnostic device (or similar).
The device gets plugged into your OBDII port or appropriate adapter (Tesla), allowing us to perform advanced analytics through a combination of onboard hardware and higher frequency software-based range queries. We will provide any hardware you need to use it.
What is in it for you?
This program is a dream for data and battery nerds. In addition to sending you all the data we collect from your car, we will send you any aggregate insights we glean from all participants. Some of the data we hope to collect may include efficiency distributions correlated to features such as speed and weather, a summary of charging behaviors and stats, and insights into usable battery capacity.
We will also offer participants opportunities to interact directly with our team of battery scientists throughout the project.
How will you be helping science and the acceleration of EV adoption?
NSF SBIR grant recipients are chosen by a review panel based on the intellectual merit of the idea and also on the broader impacts of the research. We will use the data we collect to give EV drivers and shoppers a more accurate assessment of their vehicle, increasing confidence and transparency in electric vehicles and the used EV market. Used EVs are shockingly affordable and this can help open the door to more widespread adoption.
Regarding our scientific mission, we want to know how accurately a machine learning model can use a large dataset of battery information to evaluate battery state of health without ever touching a vehicle. This program gets us one step closer to an answer.
What is Geotab?
Geotab is a technology company that regularly serves commercial fleets with web-based analytics and diagnostics. They have provided devices to over 2 million fleet vehicles, including similar research projects with public utilities like Tacoma Power. Learn more at geotab.com/about.
Does this void my warranty?
No! Plugging an OBDII device into a vehicle’s OBDII port does not void any warranties. For example, these same ports are used by mechanics during emissions testing.
What if I change my mind?
No problem! Just let us know and send back the device. There is no commitment.
How will you choose participants?
We will select drivers to receive devices based on how many applicants we get and what sort of vehicles they drive. We will likely target one or two make/models first, but plan to expand over time from there.
