IEC？TS？62257-8-1:2018（E）提出了简单、廉价的对比试验，以便在汽车用浸没式铅酸蓄电池组中轻松识别光伏单个电气化系统最可接受的模型。对于项目实施者来说，在发展中国家的实验室测试当地制造的汽车或卡车电池用于项目的能力可能特别有用。本文件中提供的测试允许根据项目的一般规范（见IEC？TS 62257-2）在短时间内使用通用技术手段评估电池的性能，以及与电池管理系统（BMS）相关的电池。 它们可以在本地执行，尽可能接近真实现场的操作条件。该文件还规定了应遵守的法规和安装条件，以确保装置的寿命和正常运行，以及装置附近居民的安全。与前一版相比，新版包括以下重大技术变更:提高适用电压水平和取消100千瓦功率限制。

IEC？TS？62257-8-1:2018(E) proposes simple, cheap, comparative tests in order to discriminate easily, in a panel of automotive flooded lead-acid batteries, the most acceptable model for PV individual electrification systems. It could be particularly useful for project implementers to test in laboratories of developing countries, the capability of locally made car or truck batteries to be used for their project. The tests provided in this document allow assessment of the batteries' performances according to the general specification of the project (see IEC？TS 62257-2) and batteries associated with their battery management system (BMS) in a short time and with common technical means. They can be performed locally, as close as possible to the operating conditions of the real site. The document provides also regulations and installation conditions to be complied with in order to ensure the life and proper operation of the installations as well as the safety of people living in proximity to the installation. This new edition includes the following significant technical change with respect to the previous edition: increase of the applicable voltage levels and removal of the 100 kW power limit.
