I think what you're really interested in is the energy density of the cells. How much the pack weighs is a function of the wh/kg of the cells and how many cells you have. If you double the energy density of each cell and double the number of cells in a pack you have the same weight as you started with. IOW it's not about kg it's about kW/kg or kWh/kg and the mass of the pack per se isn't that relevant.BnBinSD wrote:Is there any info on how much each vehicle's battery pack weighs? I've always wondered if some mfr's have an edge in this area, or they're all pretty much the same.
You'll see the biggest differences in mass at the anode.
