acing the challenges of global warming and extreme weather, energy conservation, carbon reduction, and sustainable development have become the direction of joint efforts of countries and international companies around the world, and they have successively proposed declarations and actions for net zero emissions by 2050. In order to achieve the goal of net zero emissions, electricity generation, the main source of my country's carbon emissions, plays a key role in the development of renewable energy and the construction of energy storage systems.

Solar power generation, wind power generation, hydropower generation, etc. are all renewable energy sources of intermittent power generation, and the power generation cannot be adjusted according to the load demand. Although the carbon reduction target can be achieved, it may cause unstable power supply, which requires an energy storage system Auxiliary stable power supply and power regulation, just like reservoirs can prevent floods and continuously supply water resources. However, it is difficult to extinguish the "thermal runaway" characteristics of lithium batteries in energy storage systems, and there have been many fire accidents in lithium battery energy storage systems in the world, so it is urgent to formulate relevant specifications or standards. Energy system voluntary product verification (VPC), with three-stage verification to ensure the safety of energy storage systems.

In order to promote the verification of outdoor battery energy storage systems, the Bureau of Standards actively understands the needs of private enterprises for the safety verification of energy storage systems, proposes a verification plan with reference to international standards and international verification practices, and assists enterprises in understanding the implementation and implementation of the verification system through 5 briefing sessions. Clarify the requirements of relevant verification specifications, and provide verification services through a third-party legal person verification team to strengthen the security of the energy storage system. The three-stage verification content is divided into "design review" before construction, "site review" after completion, and In the "regular test" every two years, in addition to the energy storage equipment safety standard inspection, the energy storage system is also required to obtain the visas of the electrical technician and fire equipment engineer before passing the examination of the Bureau of Standards.

• "Design review" stage : Before the construction of the energy storage site, a third-party verification agency will confirm whether the design of the site and the components planned to be used meet the requirements of the verification specifications. The case field is built to ensure the safety of the energy storage field equipment.
• "Site review" stage : After the construction of the energy storage site is completed, a third-party verification agency will conduct a site safety assessment and on-site safety test to confirm whether it meets the requirements of the verification specification, and then issue a verification certificate after being reviewed by the Bureau of Standards. To ensure the safe operation of the energy storage field.
• "Periodic test" stage : Due to the long life cycle of the energy storage system, in order to continuously ensure the safe operation of the energy storage site, a safety assessment and on-site safety test are conducted by a third-party verification agency every 2 years to confirm whether the energy storage site is still safe. Meet the requirements of verification specifications to reduce the probability of accidents in the energy storage field that has been used for many years.

In order to achieve the goal of net zero emissions in 2050, the government actively promotes energy transformation and promotes the use of renewable energy, and encourages the construction of energy storage systems. However, in the case of many accidents in foreign energy storage systems, how to promote the development of energy storage systems while ensuring the safety of energy storage systems and related equipment is an important issue. In addition to promoting the "Battery Energy Storage System Project Verification" provider as the standard for setting up energy storage systems, the Bureau of Standards, Inspection and Quarantine also continues to pay attention to the development trend of international energy storage and review and revise relevant regulations on a rolling basis, in order to improve the safety of energy storage systems At the same time, it assists local enterprises to connect with international standards.
