As Taiwan advances its energy conservation and carbon reduction goals, the adoption of renewable energy sources like solar power is on the rise. With this shift, lithium battery-based energy storage systems are becoming increasingly common in homes and communities. To safeguard consumer safety and ensure product reliability, the Bureau of Standards, Metrology, and Inspection (BSMI) announced on December 20, 2024, that "Residential Lithium Battery Energy Storage Appliances" and their associated "Power Conversion Systems" will be subject to mandatory inspection. This proactive measure underscores the BSMI's commitment to protecting consumers by addressing the potential risks associated with these emerging technologies.
Lithium battery appliances, while critical to renewable energy solutions, carry higher safety risks if not properly designed or manufactured. Substandard products can lead to thermal runaway incidents, posing significant dangers to users. To address these concerns, the BSMI convened three briefing sessions with industry associations and manufacturers, receiving no objections to the proposed regulations. The new requirements mandate compliance with standards for electrical safety, electromagnetic compatibility, grid connection safety, and, notably, thermal runaway propagation resistance. These measures aim to ensure that lithium batteries can withstand potential thermal events, significantly reducing risks.
The inspection requirements apply to "Residential lithium Battery Energy Storage Appliances" with a battery capacity of up to 20 kWh, and "Power Conversion Systems" with a capacity of up to 20 kW, including devices designed for bidirectional power transfer or integration with solar power systems. Starting July 1, 2026, these products must successfully complete the inspection process before being imported or released from production premises. Companies can apply for Registration of Product Certification upon announcement of the notice of adoption. Products that are certified will be permitted to display the "Commodity Inspection Mark" (example attached) before the official implementation date.
The BSMI urges companies to ensure the safety of products and correctness of labeling so as to protect consumer right and safety. On the other hand, consumers should only buy products bearing the Commodity Inspection Mark to guarantee safety and compliance. Moreover, the products should always be installed by a qualified electrical contractor approved by the companies.
