Requirements for storage areas and
containers
Used or defective high-voltage batteries with
lithium-ion technology still contain a high level of
electrical and chemical energy in the form of
electrolytes. Since the condition of the battery is
no longer monitored by the internal battery
management system during storage, appropriate
precautionary measures must be taken.
The storage requirements depend on the condi-
tion of the high-voltage battery as per the
assessment protocol in WIS for evaluating trans-
portability.
A distinction is made between:
• Storage of high-voltage batteries which are
safe for transport/undamaged
• Storage of high-voltage batteries which are
not safe for transport/damaged
and in the case of high-voltage batteries which
are safe for transport/undamaged, the following
distinction is made based on fire protection
requirements:
• Storage with sprinkler protection and
• Storage without sprinkler protection

High-voltage battery
Storage of high-voltage batteries which are
safe for transport in storage facilities with
sprinkler protection
When storing high-voltage batteries in storage
areas with sprinkler protection
requirements must be taken into account:
• They must be stored at a distance of 2.50 m
from other stored materials. Alternatively a
partition wall made of non-combustible
material can be installed. The partition wall
must be at least 1 m higher than the material
stored adjacent to it.
• The maximum surface area of parts storage
areas is 75 m²
• Maximum storage height 1.60 m, or
• Storage in protected storage racks
(e.g. HHS 4 as per VdS CEA 4001)

The ceiling sprinkler system must be designed as
per the applicable sizing requirements for sprinkler
systems (e.g. VdS CEA 4001), packaging must be
taken into account
