I was wondering why SoH gets reported haphazardly, knowing how it affects value so much. Any thoughts?

    Problem is: who pays enough to make this worth anyone’s while? A business must be profitabel.

    There’s a few companies trying to standardize battery health ratings, sort of like Carfax, but for the batteries specifically.

      This would be big, and I wonder what it’d do to the secondary market of EVs.

      I think refurbishing and replacing EV batteries are still a grey area, how do you haggle the sale of an EV with 70% battery life and the looming unknown and headlines for deeep deeep 8 figure replacement quotes out there lol

    car manufacturers have no incentive to make it easy for consumers to know the true state of their batteries. they want you to come to them for expensive diagnostics and repairs. it’s all about the $$$.

    There are quite a few companies that provide this service in Europe. Usually it works by putting a device in the OBD port and then measuring the amount of energy which is used as the car is driven over time. There are also second hand EV dealers that provide this information as standard, for instance DriveGreen in the UK provides Moba battery reports for all the cars it sells:

      I just clicked on a few Konas and Ioniqs and they all said ‘SoH certificate available soon/on request’

    not sure the concern over “battery replacements” is justified. people are overly concerned about longevity, when lithium ion chemistry has been studied and tested for years. (long before EVs were a thing).

    we replace laptops more often than cars. is that because the laptop gets old or the battery dies?

    people aren’t concerned about batteries in hybrids… hybrid batteries aren’t replaced either.

    Toyota is turning to startup Redwood Materials for critical battery materials

    https://techcrunch.com/2023/11/16/toyota-turning-to-redwood-materials-critical-battery-materials-us-factory/

    The effort was announced as the first batch of Toyota Prius vehicles that were released 20 years ago retired from the road. And it will only grow. Toyota’s battery lifecycle ecosystem is forecast to include the recycling, remanufacturing and repurposing of the nearly five million current operating units, according to the automaker.

    EV batteries can be repurposed as grid storage to reduce battery supply chain impacts: report

    https://www.utilitydive.com/news/ev-batteries-repurpose-recycle-grid-storage-microgrid-nrdc/686200/

    Repurposing old batteries from electric vehicles in alternative energy storage applications – like at fast-charging stations or rooftop and microgrid storage systems – is one of the ways to extend EV battery lifespans and electrify the transportation sector in a more sustainable manner, according to a new report from the Natural Resources Defense Council.

      Yup as others have pointed out, battery tech has come a long way, but still has a loooong way to go before “we don’t need to worry about battery health” or the cost of refurbishing/replacing them is a cost incentivized “maintenance” thing.

      Batteries degrade over time. It’s what they do.
