The secondary use of power batteries is an important way for the battery industry to reduce emissions. This document defines the secondary use of power batteries as the reuse of batteries with high safety and capacity. Retired power batteries with good capacity retention, after dismantling, sorting, testing, and reassembly processes, are used in low-speed electric vehicles (excluding electric bicycles). The power batteries are reused in typical scenarios such as "vehicles), backup power for communication base stations, and small-scale energy storage." This cascade utilization of power batteries extends their lifespan and... Reducing the resource and energy consumption in producing new batteries and avoiding related greenhouse gas emissions are crucial for promoting green development in industries such as new energy vehicles and power batteries. These important measures for low-carbon development will help promote the achievement of my country's carbon peaking and carbon neutrality goals. This document, based on the identification and analysis of greenhouse gas emission sources and types related to baseline and project scenarios, proposes dynamic... The method for quantifying greenhouse gas emission reduction in battery reuse projects aims to guide the scientific, rational, and prudent evaluation of retired power battery reuse projects. Estimate greenhouse gas emission reductions. To facilitate domestic and international exchanges, and in accordance with the relevant requirements of the Intergovernmental Panel on Climate Change (IPCC), this series of documents... The unit of measurement is expressed in the form of "International Unit of Measurement for Substance (Element)" or "Substance (Element) International Unit of Measurement", such as kgC. The terms "kg carbon", "kgCO2e" represent the equivalent of kilograms of carbon dioxide, and "Nm3" represents cubic meters under standard conditions. Project-based assessment of greenhouse gas emission reductions Technical Specifications for the Cascaded Utilization of Power Batteries

1 Scope

GB/T 46565-2025 is the Chinese national standard covering counting the carbon saved by giving a retired EV battery a second life in storage rather than shredding it - the baseline of a new battery built instead, the boundary, the remaining capacity and life assumed, and the monitoring. First edition. Issued on 31 October 2025, it has been in force since 31 October 2025.

This document specifies the content, procedures, project boundary determination, and emission reduction assessment for greenhouse gas emission reduction projects involving the cascade utilization of retired power batteries. Source identification, greenhouse gas types, project and baseline scenarios, emission reduction calculations, monitoring and data quality management, and emission reduction assessment reports. prepared by. This document applies to projects involving the secondary use of retired power batteries. The scenarios for secondary use include low-speed electric vehicles (excluding electric bicycles) and communication... Backup power supplies for base stations, small-scale energy storage systems, etc. This document does not apply to electric bicycles or large-scale energy storage projects.
