Along with the phase-out of the subsidy of governmental fund as well as the continually tightened EV standards & regulations for technical requirements, nevertheless, how to guide enterprises to manufacture much more energy-saving & environmentally-friendly battery electric vehicles, how to popularize 'green' consumption, and how to readily help the consumers in screening out their suitable EVs from a big cluster of vehicle types? Based on sufficient investigation & study and the assimilation of foreign experiences, and in combination with the Chinese development level of auto standards, technologies and economy, China Automotive Technology & Research Center (CATARC) has organized the formulation of EV-TEST (Electric Vehicle Test & Assessment) Specifications, and issued these Management Rules. EV-TEST focuses on various performance aspects attracting the immediate attentions of EV users in the actual service process of vehicles; through multi-dimension objective testing, it performs all-round assessment over the overall performance of EVs, and makes available much more comprehensive EV performance data & star rating which are much closer to the real-world operation status. The EV-TEST conducts performance assessment over complete vehicles of EV from five aspects, i.e., “range, electricity consumption, charge, safety, and power performance”, featuring "strict standard, normalized test, and independency & impartiality”; the final assessment result is presented in the form of directly quantified comprehensive star level rating, in addition to the single-item score of performance. Along with the incessant advances of the EV technologies and the continual improvement of related standards, EV-TEST will get continual improvement and amendment, so as to keep improving the satisfaction of EV product users, guiding the auto chain in realizing the 'green', low-carbon development, popularizing 'green' consumption, motivating NEV manufactures to maintain uplifting the innovative capability & managerial proficiency, cultivating the influential power of product brand, and promoting the healthy, sustainable development of the auto industry. 3 Chapter 1 1. Objectives 1.1 Purposes General EV-TEST aims to, in consideration of the focal points of consumers, establish an independent, impartial, and high-standard test and assessment system for the comprehensive performance of EVs. This system will objectively depict the comprehensive performance information of EVs currently in sales, motivate the highlighting of vehicles with excellent overall performance or salient single-item performance, and provide the consumers with important references; moreover, it will motivate the manufacturers to pay attentions to the improvement of EV technologies and consumers' actual experiencing of car use, thus keeping uplifting the comprehensive performance of vehicles and the satisfaction of users. 1.2 Explanations (1) EV-TEST establishes the system of indices and formulates the testing and scoring methods, specifically in consideration of the actual use conditions of EVs and the focal attentions of the consumers upon purchase of EVs. Up to now, a series of national standards have been formulated specifically for EVs, which, however, fail to completely cover the critical performance indices cared by the consumers; also, whereas EV performance is largely affected by ambient conditions and service status, the existing national standards, merely representing the minimum requirements for vehicle admittance, cannot provide the consumers with much more all-round information. In such context, EV-TEST, focusing on various performance aspects immediately concerned by consumers, establishes a comprehensive test and assessment system, citing the test methods specified in national standards, in addition to the test procedures of some foreign leading standards; specifically, in consideration of the test items not covered by domestic & foreign existing standards, new test methods are formulated through study. (2) Whereas the experiencing of consumers over all-round performance of EVs comes from various aspects, there is no way to establish a test and assessment method covering all the performance indices, at present EV-TEST merely focuses on the critical performance involving consumption experiencing. Affected by different road conditions, ambient conditions and different car-using habits of different population groups, EV performance behaves somewhat differently, while EV-TEST makes great efforts in enabling the consumers to get the assessment results close, as much as possible, to the real-world conditions. (3) Considering the normal offsets of vehicles and tests, vehicle manufacturer is permitted to compare the test results of EV-TEST with the results of the tests possibly conducted by the enterprise itself, and notify any difference found by it; meanwhile, enterprise may furnish its test results for the comparison purpose, and, in consideration of concrete situations, the test will be verified. Upon scoring, however, these data furnished by enterprise would not be taken as reference, but these data will be kept secret. (4) Along with the implementation of EV-TEST, the improvement in EV technology, and the enhancing of related standards and test capabilities, we reserve the rights to improve the test items, test methods as well as scoring procedures and assessment clauses, so as to provide consumers with vehicle performance information as much as possible, enable the assessment of EV-TEST to keep preferably close to the actual car-use experiences of consumers, keep motivating the technical and product advances of EV manufacturers as well as the improvement of innovative development capability & brand influential power, and promote the sustainable development of the auto industry. 2. Management body China Automotive Technology and Research Center (CATARC) is the management body of EV-TEST. The EV-TEST Management Center is specifically estebilshed for taking responsibility 4 for the EV-TEST organization and implementation, concretely concerning: finalization of yearly plan and financial budget, selection of vehicle type for assessment, ascertaining of assessment result, handling of disputes and hard issues, and decision of temporary matters through consultation, etc. Under EV-TEST Management Center, there are General Affairs Department, Test and Assessment Department,, of which the respective duties are as follows: (1) General Affairs Department -- Proposing yearly execution plan and financial budgets; analyzing and proposing vehicle type for assessment; purchasing vehicles; planning tests; exchanging and communicating with enterprises; unfolding international cooperation. Releasing EV-TEST assessment results; managing EV-TEST website and other ; special columns of designated magazines; propaganda on mass media; carrying out business propaganda and enhancing EV-TEST. (2) Test and Assessment Department – Collecting related technological information; making and amending assessment procedure; responding for technology exchange; supervising supervising test execution; conducting assessment based on test results; managing test and assessment data. 3. Notes on vehicle group classification Considering the differences of various EV categories as to the corresponding target consumer populations and use scenarios, EV-TEST, based on grouping of vehicle categories, establishes corresponding testing & assessment methods. In consideration of the current distribution status of vehicle types on the market, EV-TEST divides EVs into two groups for assessment, concretely: a) Micro EV group: Passenger car less than 4 m in length; b) Conventional EV group: Passenger car other than in the micro EV group. Later on, along with the development of EV product and market, the grouping method in the revised version of EV-TEST will be adjusted considering the actualities. 4.
