Scope

Scope: This document specifies the terms and definitions, evaluation index system, evaluation methods, and grade classification for the "Leader" standard evaluation of power batteries used in electric vehicles. This document is applicable to the enterprise standard level evaluation of lithium-ion power battery systems installed in pure electric vehicles, primarily intended for high-energy applications. Relevant institutions can refer to it when formulating "Leader" evaluation schemes for enterprise standards, and enterprises can also use it as a reference when developing their own enterprise standards. Main technical content: 4.2 Classification of evaluation indices 4.2.1 The indices included in the "Leader" standard for power batteries used in electric vehicles are divided into basic indices, core indices, and innovative indices. 4.2.2 Basic indices include overcharge protection of the battery system, external short-circuit protection of the battery system, and external fire protection of the battery system. 4.2.3 Core indices include energy efficiency of the battery system, low-temperature discharge performance of the battery system, capacity loss during storage, peak discharge power at normal temperature of the battery system, peak charging power at normal temperature of the battery system, and heat dissipation of the battery system. Core indices are divided into three grades, including advanced level, equivalent to a 5-star level in the enterprise standard ranking list; average level, equivalent to a 4-star level in the enterprise standard ranking list; and benchmark level, equivalent to a 3-star level in the enterprise standard ranking list. 4.2.4 Innovative indices include dynamic impact resistance performance at the bottom of the battery system, voltage consistency, and waterproof performance of the battery system. Innovative indices are divided into three grades, including advanced level, equivalent to a 5-star level in the enterprise standard ranking list;
