IEEE 3365:2025

New IEEE Standard - Active - Draft.
As the sales of EV continue to increase and the 1 ir service life extends, the lithium-ion batteries, the core components of EV, face challenges in terms of performance degradation and safety. Therefore, regular inspection of battery state is crucial. Traditional battery testing methods involve dismantling the battery pack, which is time-consuming, costly, and requires harsh testing conditions. Furthermore, since EV users are unable to obtain battery data and monitor its health status during daily use, this leads to concerns about vehicle safety and range anxiety. This guide specifies a performance index that includes the information that EV users are concerned about, simplified testing procedures and provides objective, third-party evaluation results. It helps users to evaluate the performance of on-board batteries and discover the batteries’ potential safety risks as well.

This guide provides an approach for testing and evaluation of on-board Lithium propulsion batteries in EVs during the routine charging and discharging process. It includes guidance for test conditions, procedures, and evaluation of results.
With increasing EV use, the demand for rapid testing and evaluation of battery status without disassembling the batteries is emerging as an urgent issue. This guide specifies a performance index that includes the information that EV owners are concerned about, simplifies testing procedures and provides objective, third-party evaluation results. It helps users to evaluate the performance of on-board batteries and discover the batteries' potential safety risks as well.
