2.3 Mechanical features
The mechanical features described in this chapter are
standard provided on this energy storage pack.
2.3.1 Galvanized skid
To be able to lift the ESS by means of a forklift, a
galvanized skid with rectangular slots is provided.
2.3.2 Galvanized and painted canopy
The unit is equipped with a galvanized steel canopy to
avoid corrosion. This process means, there is a
considerable barrier between the steel plate and air
ensuring that the painted surface is not compromised.
The pieces are also cut with a Nitrogen high-pressure
laser (prevents from rust while its production). And
they are all finished and protected with a powder
coating paint.
Also rain caps are placed in the most sensitive parts of
the machine to protect from water ingress.
2.3.3 Lifting beam and sling guides
A lifting beam is attached to the unit base frame. This
single lifting point will allow to lift easily the ESS.
In order to secure the position while transport, use the
guides placed in the roof to avoid any canopy damage
with the proper slings.
This is not a lifting system alternative.
2.3.4 Data plate and serial number
The ESS is furnished with a data plate showing the
product code, the unit number, the energy stored and
the power output (see “Data plate” on page 75).
The serial number is located on the front side of the
canopy.
2.4 Electrical features
The electrical features described in this chapter are
standard provided on this ESS.
2.4.1 Lithium ION batteries
Lithium-iron-phosphate (LiFePO4 or LFP) is the
safest of its family. It also does not need to be fully
charged to perform correctly as other chemistries
need. Service life even slightly improves in case of
partial charge instead of a full charge. This is a major
advantage in addition, its wide operating temperature
range, excellent cycling performance, low internal
resistance and high efficiency.
LFP is therefore the chemistry of choice for very
demanding applications.
Each battery is connected and controlled by the BMS
(Battery Management System) that makes possible
the communication between components and learn
from each performance, as for example, get
automatically their cells balanced.
