"Another cool feature of the dash display I haven't seen anyone mention yet is the battery capacity gauge. The SOC display on the far right has 12 blue and white bars, each indicating about 2 kWh, but the matching 10 white and two 2 red bars to the right of those SOC bars aren't just a fixed legend, but are an active display of battery pack capacity that will vary in the short term due to extremes of temperature and in the long term as the pack ages.
When the top two capacity bars don't light anymore, the pack will have lost nearly the 20% of capacity that Nissan figures would indicate end of life, at least for EV service.
Nissan hopes to develop a secondary market for the "80% packs" for use as backup batteries and in off-grid wind and solar systems. Trade-in value would reduce the net cost of a replacement pack for EV owners."
