In response to the challenges of global climate change, a global wave of green and low-carbon energy transformation is taking shape, with residential energy storage, especially for households, becoming an increasingly popular choice for many foreign families.

In response to the challenges of global climate change, a global wave of green and low-carbon energy transformation is taking shape, with residential energy storage, especially for households, becoming an increasingly popular choice

Currently, the market demand for residential energy storage can be classified into two main categories. The first category includes regions such as Europe and North America, where electricity prices are relatively high. In these areas, the primary goal of installing residential solar energy storage is to achieve cost-effectiveness in electricity usage. The second category includes regions like Southeast Asia and Africa, where unstable power grids are prevalent. In these areas, the main purpose of residential energy storage installations is to ensure a stable electricity supply.-Sunpack Energy will do the best for all the world clients.
For domestic energy storage companies, the primary market for residential energy storage lies overseas, making international expansion an inevitable path. Energy storage is a crucial technology and foundational equipment supporting new power systems. Different countries and regions have strict certification standards and entry barriers in place.

Overall, the main certification systems that are predominantly encountered include four categories,

1,North America: UL certification system

2,Europe: CE certification system;

3,Australia: CEC certification system

4,Japan: JIS certification system

   2. This presentation will focus on highlighting the key testing aspects of North American UL certification and European CE certification,

North American UL Certification: This certification is applicable to the North American region and primarily focuses on safety testing. The certification process typically takes around 2 months. UL certification holds high recognition in the energy storage field as a joint standard for the United States and Canada. UL 9540: Represents comprehensive functional safety certification for enclosed energy storage systems, emphasizing mechanical, electrical, and environmental testing.

UL 9540A: Focuses on fire safety. UL 9540A testing primarily evaluates battery energy system installation parameters, ventilation requirements, fire facilities, fire strategies, and response measures to reduce thermal runaway risks and enhance system safety response levels.

UL 1973: Certification requires various tests for energy storage lithium battery packs, including combustion tests, overcharge protection tests, over-discharge protection tests, temperature shock tests, etc., to ensure safe operation of battery packs under various extreme environments.

European CE Certification: IEC/EN 62619: Emphasizes safety requirements for energy storage batteries and battery systems. It includes external short-circuit, impact, drop, thermal abuse, overcharging, forced discharge, and other safety tests for battery cells and modules. Additionally, it evaluates battery management system (BMS) functions such as overcharge voltage protection, overcharge current protection, overheating protection, and resistance to thermal runaway propagation.

IEC/EN 62477 or IEC/EN 62109: Focuses on general safety standards for energy storage PCS (Power Conversion System). It primarily addresses requirements related to electrical shock prevention, energy containment, fire prevention, heat injury prevention, mechanical and noise injury prevention, as well as environmental stress that the product might undergo during operation, storage, and transportation.

VDE 2510: An essential certification for entering German-speaking regions. It covers most safety risks associated with energy storage systems, including electrical safety, battery safety, electromagnetic compatibility, functional safety, energy management, transportation safety, installation safety, and decommissioning management. In May 2018, the new standard VDE-AR-E 2510-2 was released, extending safety requirements for energy storage systems to grid-side connections.

Other:

Lithium Battery UN38.3: Applicable almost globally, this involves safety and performance testing. It's part of the United Nations Manual of Tests and Criteria for the transportation of dangerous goods, Section 38.3. It requires simulated conditions, temperature cycling, vibration, impact, external short-circuit at 55°C, overcharge, forced discharge tests, among others, to ensure safe transportation of lithium batteries

If lithium batteries are not installed together with equipment and if each packaging contains more than 24 cells or 12 batteries, a 1.2-meter free fall test is also required.

Aviation/Maritime Transportation Identification Report: For products containing batteries originating from China (excluding Hong Kong), the final aviation transportation identification report must be reviewed and issued by a hazardous materials identification organization directly authorized by the Civil Aviation Administration of China.

With the continued heat in the energy storage sector, global renewable energy giants are also accelerating their overseas energy storage market expansion.
