混合动力道路车辆. 废气排放和燃料消耗测量. 第2部分: 外部可充电车辆

[中文适用范围]： 适用于具有以下特性的车辆： - 混合动力电动汽车(HEV)，配备内燃机(IC)和车载可再充电能量存储系统(RESS)，该系统由外部电源供电。 - 在CD状态（RESS中电能被消耗）之后是CS状态，其中燃油能量被消耗以维持RESS中的电能。 - 假设只有电池作为车辆的RESS。 - 驾驶时不会对RESS进行充电，除非通过再生制动或通过IC驱动。 - 未包含为RESS调理目的的外部充电。 NOTE：无轨电车和太阳能汽车不在范围内。 根据相关区域适用驾驶测试(ADT)标准定义，车辆被归类为乘用车或轻型货车。 对于IC发动机，仅使用液体燃料（例如汽油和柴油）。 [外文原描述]： This document specifies a chassis dynamometer test procedure to determine the end of the charge-depleting state (CD) and consumed electric energy during CD state. The identification of the end of the CD state is an important step for procedures to determine exhaust emissions and fuel consumption. Final determination of exhaust emissions and fuel consumption is not included in this document. This document applies to vehicles with the following characteristics. — The vehicles are hybrid-electric road vehicles (HEV) with an internal combustion engine (ICE) and an on-board rechargeable energy storage system (RESS) for vehicle propulsion which is supplied with electric energy from an external electric power source. — A CD state, in which the electric energy in the RESS from an external electric power source is consumed, is followed by a charge-sustaining (CS) state in which the fuel energy is consumed sustaining the electric energy of the RESS. — Only batteries are assumed as the RESS of a vehicle. — The RESS is not charged while driving unless by regenerative braking and/or by generative operation driven via the ICE. — External charge for the purpose of conditioning of the RESS is not included. NOTE 1 Trolleybuses and solar powered vehicles are not included in the scope. — The vehicle is classified as a passenger car or light duty truck, as defined in the relevant regional applicable driving test (ADT) standard. — For the ICE, only liquid fuels (for example, gasoline and diesel fuel) are used. NOTE 2 In the case of vehicles with ICE using other fuel [for example, compressed natural gas (CNG), hydrogen (H 2 )], this document can apply except the measurement of consumed fuel; otherwise the measurement method for those using the corresponding fuel can apply. — The nominal energy of the RESS is at least 2 % of the total energy of consumed fuel over an ADT
