T/GHDQ 119-2023 "Leader standard" evaluation requirements for pure electric passenger cars in high-cold regions

Scope

Scope: This document specifies the terms and definitions, evaluation index system, evaluation methods, and grade division for the "Leader" standard evaluation of pure electric passenger cars in high-cold regions. This document is applicable to the enterprise standard level evaluation of pure electric passenger cars in high-cold regions. Relevant institutions can refer to it when formulating enterprise standard "Leader" evaluation schemes, and enterprises can also use it as a reference when formulating their own enterprise standards. Main technical content: 4.2 Classification of evaluation indices 4.2.1 The evaluation indices for the "Leader" standard of pure electric passenger cars in high-cold regions are divided into: basic indices, core indices, and innovative indices. 4.2.2 Basic indices include: startability, vehicle battery energy balance, vehicle static current, defrosting, rearview mirror heating, and seat heating. 4.2.3 Core indices include: power performance, crawling start, vibration and noise, and heating. 4.2.4 Innovative indices include: driving range, low-temperature power consumption, rapid charging, steering wheel heating performance, and front windshield heating performance. 4.2.5 All basic indices, core indices, and innovative 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; - Benchmark level, equivalent to a 3-star level in the enterprise standard ranking list.
