alex vallette here (cofounder and ceo): shipping in the usa will resume in september. we had to suspend because of tarifs but now we have a warehouse on the east coast so things should be much more optimized as the tariffs will apply only on cost of goods ans not on the consumer price. subscribe to the newsletter to stay tune (we only send one mail every two weeks)
(Gouach cofounder) There's an app which shows you the voltage level of each cell, and the battery will auto-rebalance them!
For second-life cells, you indeed have to match the cells, we don't necessarily expect people to do that themselves, but we will partner with battery recyclers to get second-life cells, test and match them, and sell back those packs at a lower price as an additional revenue stream for the recycling industry!
Our battery would be perfect for this kind of use-case
For the shaking of contacts, rest assured that: our batteries get tested by third-party authorities like any other batteries, and go through intense stress-test (check https://www.instagram.com/p/C-c_NEbtE4N/ for an example)
And as a second proof, our batteries have been in use in a free-floating mobility startup, Pony, for around 3+ years, they have been subjected to all kind of heat, cold, rain, snow, people kicking bikes, people throwing bikes in the river, etc, and they are working great!
Hi!
Thanks for coming here.
I have a question - how does the device aid in identifying in which cells have gone bad, and then do the necessary rebalancing to match the load level of the cells in the string?
Also, cell replacement is a concern in EVs that placing in a cell of different make and age to the existing ones will mean that cell will have a different charge curve to the others, making very easy for the pack to go 'out of sync' again. How do you address this issue?
You also mentioned that you spent a huge amount of time on making sure the contacts stay in place during the shaking that comes with riding a bike - which is super important as jumpy contacts could cause DC arcing which is a fire hazard.
How would you ease the concern that such a thing absolutely cannot happen?
