It wouldn't make a lot of sense to have universal batteries as it would also limit the designs of the car if it were legislated. permalink fedilink source parent hideshow 3 child comments replies: [–] dynamojoe@lemmy.world 12 points 3 years ago (2 children) Universal batteries would be bad, but standardized batteries would be great. If a battery has certain dimensions and gives a certain output, and can regulate itself as to charge and discharge, it doesn't matter what chemistry it uses or internal cells it has. We have had D, C, B, A, AA, AAA, etc., for years and manufacturers got along just fine within those specs. Removable batteries are already a thing with Gogoro scooters in Taiwan and I think at least one car brand in China. permalink fedilink source parent hideshow 2 child comments replies: [–] atzanteol@sh.itjust.works 6 points 3 years ago I don't know if the industry is mature enough for that. There are different voltages, max power outputs and sizes. A set a size and voltage defines nearly everything. Standard specs are great for something that is replaced frequently (alkaline batteries). It's less needed for things that are replaced rarely. permalink fedilink source parent [–] a_spooky_specter@lemmy.world 2 points 3 years ago Those are cells not packs. A cell based pack uses cells in a module that then are combined to create a pack. Standardizing is not as easy as people make it out to be. permalink fedilink source parent [–] sunbytes@lemmy.world 5 points 3 years ago (1 child) I know a guy who started a company to do exactly this (in Europe only for now). So the battery swap idea is out there, and being acted upon. permalink fedilink source parent hideshow 1 child comment replies: [+] InternetTubes@lemmy.world 6 points 3 years ago* (last edited 3 years ago) [removed by mod] permalink fedilink source parent [+] sweetdude@lemmy.world 1 point 3 years ago* (last edited 2 years ago) [deleted] permalink fedilink source parent
