Problems solved by technology

The full-charge mileage marked on the electric two-wheeler manual is very important to consumers, but there is no experimental test instrument and method for calibration. At present, the road test methods used by various companies are not comparable, because Driver's human factors, road conditions, environmental conditions (wind speed, etc.) make the measurement results poor repeatability

Embodiment 1

[0051] A method for detecting rated continuous output power of an electric two-wheeled vehicle, comprising the steps of:

[0052] In the first step, the inspector drives the electric two-wheeled vehicle 1 to be inspected on the mechanical transmission system of the electric two-wheeled vehicle performance testing device, and places the rear tire 3 (drive wheel) between the main rear wheel drum 9 and the rear wheel auxiliary drum 10 Between, the front tire 4 is on the front wheel drum 8; as Figure 1-Figure 3 As shown, the electric two-wheeled vehicle performance testing device includes a mechanical transmission system and a control sampling system; wherein, the mechanical transmission system mainly includes a synchronous toothed belt and a pulley 6, a front wheel pulley 8, a rear wheel main pulley 9 and a rear wheel auxiliary pulley 10. One end of the synchronous toothed belt and the pulley 6 is connected with the front wheel drum 8 through the transmission shaft, and the othe...

Embodiment 2

[0070] A method for testing the braking performance of an electric two-wheeled vehicle, comprising the steps of:

[0071] In the first step, during the inspection, the inspector drives the electric two-wheel vehicle 1 under inspection to the mechanical transmission system of the electric two-wheel vehicle performance detection device, and puts the rear tire 3 of the electric two-wheel vehicle 1 under inspection (Drive wheel) is placed between the rear wheel main drum 9 and the rear wheel auxiliary drum 10, and the front tire 4 is on the front wheel drum 8. Since the rear tire 3 and the front tire 4 of the electric two-wheeled vehicle 1 under inspection are connected through the synchronous toothed belt and the pulley 6, the hub motor 2 drives the rear tire 3 to rotate, and the rear tire 3 drives the rear main drum 9 and the rear auxiliary drum 10 rotate together, and drive the front wheel drum 8 to rotate through the synchronous toothed belt and the pulley 6. According to the ...

Embodiment 3

[0086] A method for testing the energy consumption per 100 kilometers of an electric two-wheeled vehicle, comprising the steps of:

[0087] The first step is to drive the checked electric two-wheeled vehicle 1 on a normal road until the checked electric two-wheeled vehicle 1 cannot run on pure electric power. At this time, the checked electric two-wheeled vehicle 1 charger is inserted into a On the socket, after the charging is completed (stand still for at least 2 hours), measure and record the charging amount G recorded by the electric meter after the two-wheeled electric vehicle is charged, the unit is kw.h (degree).

[0088] In the second step, the inspector pushes the checked electric two-wheeled vehicle 1 manpower onto the mechanical transmission system of the electric two-wheeled vehicle performance testing device energy), the rear tire 3 (drive wheel) of the electric two-wheeled vehicle 1 to be checked is placed between the rear wheel main drum 9 and the rear wheel aux...

Abstract

The invention discloses an electric two-wheeled vehicle performance detection method. The method comprises the steps of: detecting rated continuous output power of an electric two-wheeled vehicle; testing overall braking performance of the electric two-wheeled vehicle; and testing 100-kilometer energy consumption of the electric two-wheeled vehicle, wherein the step of testing the rated continuousoutput power of the electric two-wheeled vehicle is adjusting an electric bicycle by an electric two-wheeled vehicle inspector to ensure that the electric two-wheeled vehicle runs on a detection testbed at a highest speed, transmitting real-time signals of a torque T and a rotation speed n to a programmable controller by a torque sensor of a built-in encoder, carrying out data processing by the programmable controller, and calculating the rated continuous output power P of the electric two-wheeled vehicle according to a formula. The method is capable of simulating riding states in practical roads, avoiding the influences of human factors, road factors and climatic factors during the road test, and providing good overall detection result repeatability and high credibility for two-wheeled carrying tools.

Description

technical field [0001] The invention relates to a performance detection method of an electric two-wheel vehicle. The performance detection includes the detection of the rated continuous output power of the electric two-wheel vehicle, the braking performance of the whole vehicle, the energy consumption and the continuation mileage. Background technique [0002] Electric two-wheeled vehicle has attracted more and more users as a kind of transportation that is not only light but also environment-friendly. The new national standard GB 17761-2018 for electric bicycles requires that the continuous operating power of the motor should not exceed 400W. According to this standard, the motor is fixed on the dynamometer and connected to the regulated power supply, motor and controller, the motor control switch is adjusted to the maximum state, the output of the regulated power supply is adjusted to make the motor run at the rated voltage, and the motor torque is gradually increased to r...
