This type of product typically weighs between 1kg-30kg and comes with AC 220V/110V output, USB port, and car charging port. Its main scenarios are camping and emergency situations.
| Detecting dimensions | core standard | Key testing content |
|---|---|---|
| Battery safety (mandatory) | UN 38.3 | Mandatory items for transportation safety. It is necessary to pass 8 tests including altitude simulation, temperature cycling, vibration, impact, external short circuit, overcharge, and forced discharge, and obtain the "Transportation Condition Appraisal Certificate" before boarding the plane/sea freight. |
| Electrical safety of the entire machine |
GB 4943.1 (Domestic, Audio and Video/Information Technology Equipment Security) UL 2743 (North American, Portable Power Standard) EN 62368-1 (European Union, Audio and Video/ICT Safety) |
Leakage current, insulation resistance, grounding continuity, mechanical strength, plug torque. Special attention: UL 2743 requires that overcharge, overdischarge, and short circuit protection must be verified under fault conditions. |
| Electromagnetic compatibility (EMC) |
FCC Part 15B (United States) EN IEC 61000-6-1/-3 (EU) |
Radiation disturbance, conduction disturbance, and electrostatic immunity. Portable power supply with inverter, EMC is a high-risk area, often returned due to interference with radio/TV signals. |
| Wireless function (such as Bluetooth/WiFi) |
FCC ID (United States) CE-RED (European Union) |
RF exposure, frequency tolerance, and occupied bandwidth. |
| Energy Efficiency and Performance |
GB/T 35590 (Domestic, Mobile Power Bank Performance) DOE (Department of Energy) |
Effective output capacity (rated capacity vs actual output capacity), conversion efficiency, static power consumption. China requires mobile power banks to be labeled with rated capacity instead of cell capacity. |
Special reminder: China's GB 31241 (Safety Requirements for Lithium ion Batteries for Portable Electronic Products) has been upgraded to GB 40165, with stricter requirements for overcharging and thermal abuse of battery packs for portable energy storage products.
The voltage is usually in a 48V low voltage system or a 400V high voltage system, with a power of 3kW-15kW, and is used in conjunction with photovoltaic inverters.
| Detecting dimensions | core standard | Key testing content |
|---|---|---|
| Battery system safety |
IEC 62619 (International, including functional safety) UL 1973 (North America, Fixed Energy Storage Battery) |
Thermal runaway propagation: Simulate single cell thermal runaway and verify whether the system can prevent fire and explosion within 5 minutes (corresponding to the mandatory requirements of GB/T 36276 in China). |
| System level fire prevention | UL 9540A (North America, Core Report) | Hierarchical progression testing: Cell level → Module level → Cabinet level → Installation level. Test data determination: 1) Fire separation distance; 2) Do you need a sprinkler system; 3) The maximum capacity allowed for installation within a building. |
| Grid interface protection |
IEEE 1547 (North America) VDE-AR-N 4105 (German low voltage) GB/T 34120 (Domestic) |
Anti islanding protection, voltage frequency response, power quality harmonic limit. |
| Electromagnetic Compatibility | IEC 61000-6-2/-4 (Industrial Environment) | Due to its frequent installation in garages/basements, the radiation immunity requirement is higher than that of portable devices. |
| Functional Safety (Software) |
IEC 60730-1 Annex H ISO 13849 |
Assessment of Battery Management System (BMS) software to prevent crashes, false alarms of SOC, and relay adhesion. |
The focus of the rules is on fire protection linkage and power grid dispatch response.
GB/T 36276 (Lithium ion batteries for electric energy storage): China's mandatory sampling standard. In addition to safety, it is required that the cycle life be ≥ 6000 times (energy efficiency ≥ 83%).
GB/T 34131 (Battery Management System BMS): BMS must pass the surge resistance (5kA 8/20 μ s) and insulation monitoring error ≤ 5% test.
GB 51048 (Design Code for Electrochemical Energy Storage Power Stations): specifies the fire separation distance, accident oil pool, and combustible gas detection linkage.
| rule | Scope of application | specific changes |
|---|---|---|
| EU New Battery Law (EU) 2023/1542 | All energy storage batteries (including portable) exported to Europe | Mandatory implementation of carbon footprint declaration starting from August 18, 2023; Starting from 2027, digital battery passports and disclosure of recycled material content will be mandatory. |
| US Consumer Product Safety Commission (CPSC) voluntary recall order | Portable energy storage sold by Amazon and Temu | Mandatory requirement to provide UL 2743 or UL 9540A test report, otherwise delisted. |
| Expansion of China CCC Certification | Partial energy storage power supply | The power adapter part under GB 4943.1 has been included in 3C. If the energy storage power supply contains an external adapter, it needs to be certified separately. |
