areas of extreme temperature variations. This deterioration can be minimized with careful preparation
for storage. A properly stored EV is much easier to return to service.
1.17.1 Storage Area Selection
When selecting a storage area, consider the following:
1. The storage area must be dry. A heated area is best, but not necessary. It should be insulated to
minimize extreme temperature variations.
2. If the building has large window areas, mask them to keep sunlight off the EV.
3. Avoid buildings in industrial areas where corrosive emissions may be present. Avoid areas close
to saltwater.
4. Consider the area’s risk of fire, theft or vandalism. Check with an insurer regarding EV coverage
while in storage.
