definition of portable energy storage:

portable energy storage means can be carried by single hand and move, at the same time, do not need to be connected to the power system of permanent storage products. This type of product can be divided into the following two types:

1. Handheld;

2. Mobile type, meeting the following conditions:

   - The weight does not exceed 18 kg, and it is not fixed, or it is equipped with auxiliary mobile devices such as wheels, which is easy to carry and use by ordinary users.

portable energy storage industry development present situation and prospect:

In recent years, portable energy storage (also known as outdoor energy storage) has become rapidly popular in the global market, and as a branch of new energy storage, it has once again attracted many eyes. In the past four years, the market for portable energy storage has expanded 23 times. The United States, as the world's largest portable energy storage application market, accounted for 47.3% of sales in 2021, mainly because American users love outdoor activities. Japan as the second largest application market, accounting for 29.6%, its application field and the United States there is a big difference, such as in the field of emergency shipments of about 500,000 units, while the outdoor application field shipments of about 50,000 units, mainly because of the frequent occurrence of natural disasters such as earthquakes in Japan, the demand for emergency power equipment is high.

Although China's portable energy storage power industry started late, but after several years of development, has become the world's largest portable energy storage power production and exporter. According to statistics, more than 90% of the world's emergency energy storage products are produced in China. In 2022, the global portable energy storage market will reach 20.81 billion yuan.

industry leader in revenue: warburg to 2022 new business income is 3.203 billion yuan, up 38.35% from a year earlier. The operating income of Zhenghao Technology in 2022 is expected to be between 2.8 and 3.5 billion yuan, an increase of about 100% year-on-year.

According to the forecast of China Chemical and Physical Power Supply Industry Association, by 2026, the global shipment of portable energy storage products will exceed 30 million units, and the total amount will reach 88.23 billion yuan.

In order to ensure the smooth entry of your portable energy storage products into the global market, BACL battery technology experts have organized the following safety specifications for you:

lithium battery portable energy storage product safety certification and testing standard of global market:

1. United States:

   - The certification standard is UL 2743:2023, and the safety certification in the United States such as UL and ETL is voluntary and can be applied selectively. If the product is to be sold on Amazon, only UL 2743 test is required.

   - The lithium-ion cell standard is UL1642, and the new UL 2580 and UL 1973 are optional cell standards.

    - note: auto emergency start power lithium battery for UL2743 applicable standards.

2. China:

   - At present, there is no special standard for such products, usually using GB-4943.1 as the main standard of the whole machine, the internal lithium battery follows GB-31241, only need to issue a quality inspection report.

3. Japan:

   - Energy storage power supply products with AC AC output are not classified as batteries, belong to PSE objects outside the product, can not apply for PSE certification.

   - Usually internal lithium battery for circular PSE certification, the whole machine can be issued according to IEC 62368-1 report plus Japan deviation safety confirmation report.

   - If the lithium battery report requires a photo of the machine, and the PSE circle logo on the machine, there may be a risk of being removed from the market. Already domestic big factory products have been removed from the Japanese e-commerce platform.

   - Note: Automotive emergency power supply because there is no AC output, usually regarded as similar to mobile power, can apply for PSE certification.

4. European Union:

   - There is currently no harmonized standard specifically for portable energy storage products, according to the EU alert market supervision sampling opinion, for AC output energy storage power supply, the market supervision believes that it has the function of UPS uninterruptible power supply. It is generally recommended to adopt EN IEC 62368-1+EN IEC 62040 standards. If the product has other functions such as lighting, other criteria need to be evaluated according to different functions. (IEC 62619:2022 standard is suitable for industrial storage battery)

5. Korea:

    - according to KC, 62619:2022 standard to KC certification. Similar to lithium battery products, CB certification is performed first, the standard is IEC 62619:2022, and then CB certification is applied for Korean KC certification.

6. Australia:

   - In accordance with AS/NZS 62368-1 and AS/NZS 4763, SAA certification is not mandatory.
