Ministry of Communications revised bus and operating bus rating

Ministry of Communications revised bus and operating bus rating

[Abstract]:
TheMinistryofCommunicationsissuedanoticeannouncingtherevisionofthe"ClassificationandRatingofOperatingBusTypes"and"ClassificationandRatingofBusTypes".Thespecificmodificationsareasfollows:JT/T888-2014"C
The Ministry of Communications issued a notice announcing the revision of the "Classification and Rating of Operating Bus Types" and "Classification and Rating of Bus Types". The specific modifications are as follows:
JT/T 888-2014 "Classification and Rating of Bus Types"
No. 1 modification
1. Add 7.2.18 as follows:
Pure electric buses and hybrid buses shall be equipped with automatic fire extinguishing devices for power battery boxes; floor covering materials shall be flame retardant, and their flame retardancy shall comply with Class B1-B of 5.1.2 paving materials in GB8624, s1 -t0 combustion performance requirements, oxygen index should be greater than or equal to 30%.
2. Add 7.2.19 as follows:
Hybrid buses shall have a driving range of not less than 50km for pure electric working conditions tested by the 40km/h constant speed method; pure electric buses shall have a driving range of not less than 200km for pure electric working conditions tested by the 40km/h constant speed method ( Supercapacitors, lithium titanate fast charge pure electric bus except).
Third, increase 7.2.20, as follows:
The ratio of the total quality of the pure electric bus and hybrid bus power battery system to the vehicle's curb weight is not more than 20%.
4. Modify the footnotes a and c of Table 4 bus rating performance indicators as follows:
a Specific power is equal to the ratio of engine rated power to maximum design total mass; the values ​​in parentheses are for 18m ≥ L > 12m articulated buses, and L is the length of the vehicle in meters (m). Pure electric buses and hybrid buses do not require comparison power.
C “After” includes rear and center; pure electric bus team engine position is not required.
For ordinary articulated buses: the engine is not required to be rear or centered;
For medium-sized high-class buses: the front engine compartment is outside the cabin and can be seen as the rear compartment.
JT/T 325-2013 "Classification and Rating of Operating Bus Types"
No. 1 modification
1. Add 8.1.22 as follows:
Pure electric buses and hybrid buses shall be equipped with automatic fire extinguishing devices for power battery boxes. Floor covering materials shall be flame retardant, and their flame retardancy shall comply with the B1—B grade of 5.1.2 paving materials in GB8624, s1-t0. For combustion performance requirements, the oxygen index should be greater than or equal to 30%.
2. Add Article 8.1.2 as follows:
Hybrid electric bus adopts 40km/h constant speed method to test the driving range of pure electric working condition should be no less than 50km; pure electric bus adopts 40km/h constant speed method to test the driving range of pure electric working condition should be no less than 200km (super capacitor Lithium titanate fast charging pure electric bus except).
3. Add 8.1.24 as follows:
The ratio of the total quality of the pure electric bus and the hybrid bus power battery system to the vehicle's curb weight is not more than 20%.
4. The footnotes a, f, and k of the performance indicators of the operating bus rating of Table 4 are modified as follows:
a front-mounted engine compartment is outside the cabin, and can be regarded as middle and rear when the vehicle's outer hatch is covered. Pure electric buses do not require engine position.
The specific power of f is equal to the ratio of the rated power of the engine to the total mass of the design. Pure electric buses and hybrid buses do not require comparison power.
The baggage compartment capacity of k super large double-decker bus is 50% of the single-class passenger car of the same class. The baggage compartment volume of the gas passenger car is 50% of the same class of fuel passenger car. The baggage compartment volume of the pure electric bus is the same class of the fuel car of the same class. %.
