One quarter of large-scale batteries have built-in fire risks caused by manufacturing defects in components, according to a new report out of the US.
Audits over six years found that 26 per cent of battery energy storage systems (BESS) have quality problems..
Although only a quarter of all problems came from cell manufacturing – half come when the battery is installed and tested on site – Clean Energy Associates say defects at this stage of a battery project are the highest risk because cells are the building blocks.
Half of all defects were caused during installation, a manual process with less stringent quality control processes, the report said.
