ISO 7176-4:2008规定了通过测量驾驶时消耗的能量和轮椅电池组的标称能量容量来确定电动轮椅（包括滑板车）理论距离范围的方法。本标准适用于最大标称速度不超过15 km/h的电动轮椅，旨在为一名残疾人提供室内和/或室外移动能力，其质量在ISO 7176-11规定的范围内。ISO 7176-4:2008还包括测试报告和信息披露的要求。

ISO 7176-4:2008 specifies methods for determining theoretical distance range of electrically powered wheelchairs, including scooters, using measurements of energy consumed while driving and the nominal energy capacity of the wheelchair's battery set. It is applicable to electrically powered wheelchairs with a maximum nominal speed no greater than 15 km/h, intended to provide indoor and/or outdoor mobility for one disabled person whose mass is within the range represented by ISO 7176-11. ISO 7176-4:2008 also includes requirements for test reports and information disclosure.
