Description of content: To achieve net-zero carbon emissions by 2050, it is expected that renewable energy power generation equipment and energy storage systems will gradually enter households and communities. Due to the risks associated with thermal runaway in lithium-ion batteries used in energy storage systems, the BSMI proposes to add secondary lithium cell blocks, battery packs (modules), and battery systems with capacity between 1 kWh and 100 kWh (inclusive), used in battery energy storage systems (BESS) into the mandatory inspection scope. Two alternative conformity assessment procedures are made available for the choice of applicants, i.e. Registration of Product Certification (RPC) or Type-Approved Batch Inspection (TABI).

Objective and rationale, including the nature of urgent problems where applicable: Protection of human health or safety; Protection of the environment
