g. Exhaustsystems
h. Deflagrationventingsystems
12.Identification of any surrounding communities, sites, and infrastructure that may be impacted as a result of an incident.
Testing
Details of any evidence based testing of the system design should be requested, for example, results of UL 9540A testing.
Design
Design features should be made clear. These may include:
Rack layout and setup
Thermal barriers and insulation
Container layout and access arrangements
Detection and monitoring
An effective and appropriate method of early detection of a fault within the batteries should be in place, with immediate disconnection of the affected battery/batteries. This may be achieved automatically through the provision of an effective Battery Management System (BMS) and/or a specific electrolyte vapour detection system.
