Nissan is working on what to do with the battery
packs inside of its Leaf EV once they have reached EOL status for automotive
duties. Once the vehicles are at the end of their life, the batteries will
still have a very large percentage of their charge capacity.
Nissan says that the battery will likely have 80%
of its original capacity when the car is ready for the scrap heap and have use
in other markets such as energy
storage. Nissan is looking years down the road when the Leaf is aging and
there are old battery packs on the market. To find a green and profitable use
for the old batteries, Nissan is pursuing the possible use for the batteries in
The push to find a viable way to recycle the
batteries also comes not long after the massive tsunami devastated parts of
Japan and blackouts were common from damaged electrical plants.
Nissan has demonstrated a new system that uses
old Leaf battery packs. The system has four Leaf batteries in a cellar inside a
Nissan building. These batteries are hooked to 488 solar panels on the roof of
the building. Nissan reports that the battery packs store energy the solar
panels create. The power created is enough to charge 1,800 Leaf vehicles per
Detroit News reports that other
carmakers are working on similar plans to reuse their EV batteries including
Toyota and Honda. These companies are working on linking hybrids with a
driver's home to form smart grids. A Leaf battery with 80% capacity could store
enough electricity for two days of use for a normal household.
