Foreword
This Standard was drafted according to the requirements of GB/T 1.1-2009. This Standard replaces GB/T 19753-2005 "Test Methods for Energy Consumption of Light-Duty Hybrid Electric Vehicle". Compared with GB/T 19753-2005, in addition to editorial changes, the main technical changes in this Standard are as follows. - the classification method of Chapter 4 in this Standard conflicted with the requirements of GB/T 19596, and therefore, the name of Chapter 4 was changed. - the test vehicle need run-in according to the manufacturer's instructions, and shall travel at least 300km within 7 days before the test. It was revised as "it shall be recommended to travel 300km at least within 7 days before the test?€? (see 6.1, and 6.1 in 2005 edition).
- speed tolerance ??2 km/h was added in "the vehicle speed is stable at 50 km/h until the engine of hybrid electric vehicle starts". The same revision shall be conducted if the same problems occur in the following articles (see 7.1.2.1, 7.1.1.1 in 2005 edition).
- the fuel consumption c1/2 (L) in the former standard was changed to c1/2 (1/ 100 km) (see Articles 7.1.2.3.5, 7.1.3.2.4, 7.1.4.1 and 7.2.3.3.5, as compared to Articles 7.1.1.3.4, 7.1.2.2.4, 7.2.2.3.5.1 and 7.2.3.2.4 in 2005 edition).
- new test methods were added as options for test methods of hybrid electric vehicle of off-vehicle charging. New test methods include operation of N circulations until the energy storage device reaches the lowest status-of-charge. The test methods may preferably reflect energy consumption of some new type hybrid power control strategy [see 7.2.3.3.4a) and 7.2.3.3.4b)].
- to make the energy consumption of hybrid electric vehicle of off-vehicle charging more visual, the energy consumption shall be required to be comprehensively expressed as two parts - fuel consumption and power supply consumption, and shall not be expressed with one part to avoid confusion (see 7.1.4.3 and 7.2.5.3). - the computing standard of other fuel was added to indicate that the calculation of other fuel is consistent with the national standard implemented synchronously (see 7.4).
- the pre-processed cycle was modified as two complete cycles. Simultaneously, fuel and power supply consumption was required to be measured in the
pre-processed cycle, and it was required that within three test cycles, the electric energy variation of vehicle energy storage device shall be less than 5% of fuel consumption. Otherwise, the test was invalid (see 7.3.1.1 and 7.3.1.2 in 2005 edition).
Test methods for energy consumption of light-duty
hybrid electric vehicles
1 Scope
This Standard specifies the test methods for energy consumption of light hybrid electric vehicles that are equipped with spark ignition engine or compression ignition engine.
This Standard is applicable to Category-M1, M2 and N1 hybrid electric vehicles equipped with spark ignition engine or compression ignition engine of which the maximum total mass is not exceeding 3.5t.
2 Normative References
The following referenced documents are indispensable for the application of this document. For dated references, only the editions cited apply. For undated references, the latest editions of the normative documents (including any amendments) apply. GB 18352.3-2005 Limits and Measurement Methods for Emissions from Light-duty Vehicle (Phase III and Phase IV in China)
GB/T 19233-2008 Measurement Methods of Fuel Consumption for Light-duty
Vehicle
GB/T 19596 Terminology of Electric Vehicle
3 Terms and Definitions
For the purpose of this Standard, the terms and definitions established in GB/T 19596 and as follows apply.
4 Hybrid Electric Vehicle Classification according to
Charging Method
The hybrid electric vehicles are classified into four categories in accordance with charging methods as shown in Table 1 according to whether the energy storage device is in need of off-vehicle charging and the vehicle are equipped with manual selection functions for travel mode.
7.1.2.2 Vehicle treatment
7.1.2.2.1 The hybrid electric vehicle equipped with compression ignition engine shall adopt Part 2 cycles specified in Attachment CA in Appendix C of GB 18352.3-2005 and subject to three cycles of continuous operation for pre-treatment.
7.1.2.2.2 The hybrid electric vehicle equipped with spark ignition engine shall adopt one Part 1 cycle and two Part 2 cycles specified in Attachment CA in Appendix C of GB 18352.3-2005 for pre-treatment.
7.1.2.2.3 Before test, the vehicle shall be subject to indoors thermal insulation under 20??C~30??C conditions and complete totally charging to energy storage device according to the requirements of Appendix A during vehicle submerging. Before the test, the vehicle shall be placed indoors under the 20??C~30??C conditions for at least 6h until the difference between the temperature of engine lubricant and coolant and room temperature falls within the range of ??2??C.
7.1.2.3 Test procedure
7.1.2.3.1 Start the vehicle normally, and conduct the test according to the requirements of Appendix C in GB 18352.3-2005.
7.1.2.3.2 The sampling shall be conducted according to the requirements of Appendix C of GB 18352.3-2005.
7.1.2.3.3 The vehicle operates according to the requirements of Appendix C in GB 18352.3-2005; if the manufacturing plant has some special document specification for gears transformation, the requirements of gear shift point of Attachment CA in Appendix C in GB 18352.3-2005 are inapplicable. Operation may be conducted in combination with product using manual and gearbox operation instruction of manufacturing plant according to the requirements of C.2.3 in Appendix C of GB 18352.3-2005.
7.1.2.3.4 The following two test methods are optional, and the manufacturer provides working principle of hybrid motor vehicle to testing organizations and proposes selected test methods and they are implemented after approval by testing organizations.
a) Sampling starts before the start of vehicle or at the same time of start and stops after the last idle speed segment completion of the suburban cycle. b) Sampling starts before the start of vehicle or at the same time of start and repeats a certain quantity of cycles continuously. Sampling stops after the final idle speed of the first suburb cycle finishes when the energy storage equipment reaches the lowest status-of-charge. The lowest status-of-charge is determined by the following procedures.
7.1.3.1.1 Discharging from the energy storage device is conducted according to the requirements of 7.1.2.1. If the manufacturing plant requires, the vehicle may be treated according to 7.1.2.2.1 or 7.1.2.2.2 before discharge.
7.1.3.1.2 Before the test, the vehicle shall be placed indoors under 20??C~30??C conditions for at least 6h until the difference between the temperature of engine lubricant and coolant and room temperature falls within the range of ??2??C. 7.1.3.2 Test procedure
7.1.3.2.1 Start the vehicle normally, and conduct the test according to the requirements of Appendix C in GB 18352.3-2005.
7.1.3.2.2 The sampling shall be conducted according to the requirements of Appendix C of GB 18352.3-2005.
7.1.3.2.3 The vehicle operates according to the requirements of Appendix C in GB 18352.3-2005; if the manufacturing plant has some special document specification for gears transformation, the requirements of gear shift point of Attachment CA in Appendix C in GB 18352.3-2005 are inapplicable.
