I'm sure this will sound like a noob question, but I'm trying to learn more on how Tesla charges the batteries in their pack. Maybe this is a question in general of all multi-celled batteries: Is it like a hose that has to fill up cups, in this case cells, that goes from cell to cell to fill or rather a hose that sprays an area at once in which each cell is filled at the same time. Or is it something entirely different? If someone can help point in the direction of learning more that would be great. The Tesla graphics and info seem to explain only how fast it takes but not the charging itself.
