GB/T 34013 Regulatory Compliance Testing of Lithium-Ion Batteries Under Low Temperature
The GB/T 34013 standard is a crucial regulatory compliance test for lithium-ion batteries, ensuring that they perform reliably and safely under low temperature conditions. This standard is particularly important given the growing use of lithium-ion batteries in various sectors such as electric vehicles (EVs), renewable energy storage systems, and portable electronic devices.
The primary aim of this testing is to verify that the battery can operate within specified limits without degrading performance or causing safety issues under cold conditions. The test simulates real-world scenarios where lithium-ion batteries are likely to be exposed to low temperatures, such as in winter climates or during extended periods of storage at lower temperatures.
The GB/T 34013 standard is part of a broader framework designed to ensure the reliability and safety of lithium-ion batteries. It specifies precise test conditions and procedures that must be followed to assess battery performance under low temperature environments. This ensures consistency in testing across different manufacturers, laboratories, and regions.
The test involves exposing the lithium-ion battery to specified temperatures for a defined duration and then evaluating its electrical characteristics such as open-circuit voltage (OCV), internal resistance, capacity retention, and impedance before and after the exposure period. The goal is to determine if the battery can maintain acceptable performance parameters within these conditions.
This testing procedure helps manufacturers ensure that their products meet regulatory requirements and are safe for use in cold environments. It also provides valuable data for quality assurance teams who need to verify that new models comply with relevant standards before release to market.
The GB/T 34013 standard is widely accepted by industry stakeholders, including government agencies responsible for enforcing safety regulations on electrical products and consumers looking for reliable performance from their devices. Compliance with this standard can significantly enhance brand reputation and customer trust.
For those involved in research & development (R&D) or procurement processes related to lithium-ion batteries, understanding the specifics of GB/T 34013 is essential. This knowledge enables them to make informed decisions about product specifications, supplier selection, and quality control measures during manufacturing stages.

| GB/T 34013 | Lithium-ion batteries - Determination of low temperature performance |
The GB/T 34013 standard is applied to ensure that lithium-ion batteries meet specific performance criteria when subjected to cold temperatures. This includes measuring the battery's ability to retain its nominal capacity, maintain safe operating parameters, and recover from suboptimal conditions after exposure.
By adhering to these standards, manufacturers can demonstrate compliance with national regulations while also ensuring product quality meets international expectations. The application of GB/T 34013 helps establish a baseline for acceptable performance levels under low temperature conditions, which is critical for maintaining safety and reliability in various applications.
Scope and Methodology
The scope of GB/T 34013 covers the determination of how lithium-ion batteries perform under low temperature conditions, specifically those that are likely to be encountered in real-world use. The methodology involves several key steps:
- Preparation of the test sample according to specified dimensions and specifications.
- Exposure of the battery to a controlled environment at the required low temperature for a predetermined duration.
- Data collection on various parameters including OCV, internal resistance, capacity retention, and impedance before and after exposure.
- Evaluation of whether the battery meets the performance criteria outlined in GB/T 34013.
The test aims to provide comprehensive insights into how well a lithium-ion battery can operate under cold conditions. By following these procedures accurately, laboratories can generate reliable data that supports regulatory compliance and product development efforts.
For quality managers and R&D engineers involved in the production of lithium-ion batteries, understanding this methodology is crucial for ensuring consistent results across different batches or models. It also allows for early identification of potential issues with design or manufacturing processes that could affect performance under low temperature conditions.
