Scope

Scope: This document specifies the basic requirements, evaluation indicators and requirements, evaluation methods, and grading standards for the product quality and corporate standards of pure electric passenger cars in high-cold regions. This document is applicable to the evaluation of the product quality and corporate standards of pure electric passenger cars in high-cold regions with temperatures ranging from -20℃ to -30℃. Relevant institutions can refer to it when conducting quality grading and corporate standard evaluations, as well as "leader" product evaluations and related certifications. Relevant enterprises can also use this document as a reference when formulating corporate standards. Main technical content: The evaluation indicators for the "leader" standard of pure electric passenger cars in high-cold regions are divided into basic indicators, core indicators, and innovative indicators. Due to the potential danger of high-voltage electricity in electric vehicles; the risk of battery pack damage caused by misuse of the vehicle, resulting in high maintenance costs or battery short-circuiting; the risk of electrical leakage after the vehicle is submerged in water; and the fact that frost on the front windshield may affect driving safety, with defrosting performance being a mandatory national standard requirement, the safety requirements of electric vehicles, bottom collision performance, water immersion performance, and defrosting performance are defined as basic indicators. The vehicle's low-temperature power performance, energy consumption, and comfort, which are highly expected by users, are defined as core indicators. The ultra-low-temperature driving range, power consumption, and low-temperature fast charging performance have always been the primary concerns of pure electric vehicle users, so the -30℃ driving range and power consumption, as well as -30℃ fast charging performance, are defined as innovative indicators.
