EV3.4.11 segments contained within the accumulator must be separated by an electrically
insulating and be fire resistant barrier (according to UL94-V0, FAR25 or equivalent) and must
subdivide the accumulator into 6MJ segments if this is not already met by the separation due to the
120VDC voltage limit.
NOTE: The contained energy of a stack is calculated by multiplying the maximum stack voltage with
the nominal capacity of the used cell(s). Documentation of segment separation must be provided in
the ESF.
