INL's AVTA EV testing terminated

Tue Jul 18, 2017 7:19 pm

I've been wondering why this page has not been updated in many months:

https://avt.inl.gov/vehicle-type/all-po ... chitecture

In response to my inquiry:
INL spokesperson:

Thanks again for your interest in INL's work producing the AVTA reports. As you probably know, INL is part of the Department of Energy's national laboratory system and receives much of its research funding and direction from DOE.

To answer your question about the light-duty vehicle testing, federal funding for the project has ended because the EV industry is maturing, which lessens the need for taxpayer-funded testing and data collection.
It is extremely disappointing that the only program that has been independently monitoring manufacturer's claims of BEV/PHEV/BEVx initial battery capacity (total and available) and battery capacity loss over time has been terminated.

This will leave EV owners with few sources of battery capacity data, apart from the inaccurate (and easily manipulated) BMS reports provided by manufacturer's.

The much-more reliable data on charge accepted can only be collected (with some effort) allowing calculation of available battery capacity by owners of EV's for which charge/discharge efficiency reports were previously collected by the AVTA, and published at the site above.

Thanks for finding out the details on this.
I too had noticed the lack of updates on the AVT site this year.
It is a real shame. This was the best site we had for comparing the actual battery details.

Wow. I had no idea. Call me disappointed, as well. :(

'19 Bolt Premier
'13 Leaf SV w/premium package (owned)
'13 Leaf SV w/QC + LED & premium packages (lease over, car returned)

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

I didn't know about this. Very sad :(

Thanx for info.
