Portable Power Supply Safety Standards

While modern power stations are built with advanced safety features, such as Battery Management Systems (BMS) and global safety certifications (e.g., UL, CE, FCC, RoHS, UN 38.3), user awareness and adherence to proper handling are paramount to prevent accidents, damage, or injury. [pdf]

FAQS about Portable Power Supply Safety Standards

What are electrical safety standards?

These standards are defined and administered by national or international agencies with various government-recognized testing laboratories able to certify compliance with such statutory regulations. The primary goal of safety standards for power supplies used in electrical equipment is to protect against fire, electric shock and injury.

What is power supply safety?

Power supply safety is a multi-faceted challenge that requires careful consideration of IEC protection classes, medical-grade standards, and safety certifications. At MicroPower Direct, we understand the importance of designing power supplies that meet these stringent safety requirements.

Do you need a safety report for a power supply?

When integrating power supplies into a system, reviewing the safety reports and certifications is a must. Certifications like the CB report (IEC 60950-1) provide vital details on a power supply’s compliance with international safety standards. These reports often include key information such as:

Are medical power supplies safe?

In medical environments, power supply safety takes on even greater significance due to the direct impact on patient care and life-supporting equipment. IEC 60601-1 standards govern the design and performance of medical power supplies, ensuring that they meet stringent requirements for safety, reliability, and performance.

What is a power supply protection class?

The International Electrotechnical Commission (IEC) outlines several protection classes to categorize the level of protection a power supply provides against electric shock. This classification is particularly important in industries such as healthcare, industrial applications, and consumer electronics.

How do I choose a power supply for medical devices?

When selecting power supplies for medical devices, these factors ensure the safety and reliability of equipment such as diagnostic machines and life-support systems. When integrating power supplies into a system, reviewing the safety reports and certifications is a must.

Solar photovoltaic panel standards

The International Electrotechnical Commission (IEC) establishes two primary standards that govern the quality and safety of photovoltaic modules: IEC 61215 and IEC 61730. These standards serve as the cornerstone for PV module certification worldwide. [pdf]

Energy Storage Equipment Cell Standards

In this article, we briefly discuss each of the 20 proposals adopted in the third edition of UL 9540. UL 9540 is a safety standard for the construction, manufacturing, performance testing and marking of grid-tied ESS. This includes electrochemical, chemical, mechanical, and thermal storage systems. [pdf]

FAQS about Energy Storage Equipment Cell Standards

Are electrochemical energy storage systems ul 9540 certified?

As a basis, electrochemical energy storage systems are required to be listed to UL 9540 per NFPA 855, the International Fire Code, and the California Fire Code. As part of UL 9540, lithium-ion based ESS are required to meet the standards of UL 1973 for battery systems and UL 1642 for lithium batteries.

Do energy storage systems need a CSR?

Until existing model codes and standards are updated or new ones developed and then adopted, one seeking to deploy energy storage technologies or needing to verify an installation’s safety may be challenged in applying current CSRs to an energy storage system (ESS).

What is an energy storage system (ESS)?

Covers an energy storage system (ESS) that is intended to receive and store energy in some form so that the ESS can provide electrical energy to loads or to the local/area electric power system (EPS) when needed. Electrochemical, chemical, mechanical, and thermal ESS are covered by this Standard.

What is the UL 9540 standard for energy storage systems?

For ESS, the standard is UL 9540, Standard for Energy Storage Systems and Equipment. UL 9540 covers the complete ESS, including batery system, power conversion system (PCS), and energy storage man-agement system (ESMS). Each of these components must be qualified to its own standard:

What if energy storage system and component standards are not identified?

Energy Storage System and Component Standards 2. If relevant testing standards are not identified, it is possible they are under development by an SDO or by a third-party testing entity that plans to use them to conduct tests until a formal standard has been developed and approved by an SDO.

What is a safety standard for stationary batteries?

Safety standard for stationary batteries for energy storage applications, non-chemistry specific and includes electrochemical capacitor systems or hybrid electrochemical capacitor and battery systems. Includes requirements for unique technologies such as flow batteries and sodium beta (i.e., sodium sulfur and sodium nickel chloride).
