5.9 Safe Technology
Each 48TL160H is made of 80 sodium nickel cells. A single cell is composed by a fully sealed
prismatic steel case which contains the active materials and the cell separator. The cells are
electrically connected by brazed/welded rigid inter-cell connectors and the resulting cell pack is
contained into a stainless steel (inner) box together with 3 heating elements and the temperature
probes.
The inner box is surrounded by the thermal insulation complex
which is composed by a number of
micro-porous silica panels with the appropriate thickness to provide the right level of insulation,
minimizing the thermal losses.
The outer stainless steel battery box contains the inner box and the thermal insulation barrier and
provides the adequate mechanical strength and a sealed construction.
All of the active materials are safely and permanently contained within the battery, which has zero
spillage and cannot leak or outgas in normal operation.
5.10 Battery Protection
Each battery has its own electrical, thermal, and mechanical protection built-in.
5.10.1 Electrical Protection
Electrical protections are considered as primary security.
Fiamm SoNick 48TL160H battery is protected against short circuit or prolonged current
overload (current above 200A will open the positive leg) by the Battery Management
System’s (BMS) ability to disconnect the battery terminals. Battery is also provided with
internal fusible link protection, (200A)
that will open the
negative leg if an over current
situation, in the remote case of non-intervention by the BMS, occurs.
