Electric bicycle chassis dynamometer system

1、 System Overview:

Electric bicycle chassis dynamometer systemMeet the testing requirements of clauses 6.3.3.1 "Rated Continuous Output Power of Electric Motor", 6.3.3.2 "Low speed Operating Torque of Electric Motor", 6.3.3.3 "No load Back electromotive force of Electric Motor", and 6.3.3.4 "Coefficient of Difference in Electric Motor Inductance" in the national standard GB17761-2024 "Safety Technical Specification for Electric Bicycles", and apply them to electric bicycle manufacturers and quality inspection institutes for electric vehicle factory type testing and quality spot checks. It can also be used for analyzing data related to electric vehicle development. The testing project includes all indicators of the electric bicycle and electric motor: front wheel braking force, rear wheel braking force, braking performance, starting performance, vehicle speed performance, maximum speed, climbing performance, undervoltage test, overcurrent test, driving range, hundred mile power consumption, battery capacity, sliding distance, rated continuous output power, low-speed operating torque, and difference coefficient of no-load back electromotive force inductance value. Humanized design and easy operation.

2、 Main technical parameters of the testing system:

Loading torque: (0-100) N.m, accuracy: Class 0.5.

Test speed: (0-30) km/h, accuracy: 0.2 level.

Current: DC (0-50) A, accuracy: Class 0.5.

Voltage: DC (0-100) V, accuracy: Class 0.5.

Electric vehicles have infinitely variable speed.

Braking force: (0-1000) N, accuracy: Level 1.

3、 Introduction to the composition of the testing system:

3.1 The testing system consists of a main control cabinet, precision DC power supply, testing platform, fixture execution mechanism, etc.

3.2 Main control cabinet: The cabinet has a beautiful appearance, easy operation, and is suitable for people of different heights to operate. A DC power voltmeter and an AC voltmeter are installed on the cabinet for measuring and testing. The lily leaves on both sides of the cabinet are used for ventilation and heat dissipation of the high-voltage cabinet. There are two 60mm diameter openings at the bottom of the cabinet for wiring, which are convenient for wiring. Install two vertical partitions in the middle of the cabinet for electrical installation.
