Introduction

According to the document user principle, GB/T 18029 "Wheelchair Vehicles" stipulates that wheelchair users, manufacturers, testing institutions and other relevant parties should pay attention

requirements for the design, performance, testing, infrastructure, and information release of wheelchair vehicles: GB/T 18029 is intended to consist of 22 parts:

--- Part 1: Determination of static stability;

--- Part 2: Determination of dynamic stability of electric wheelchairs;

--- Part 3: Determination of braking performance;

--- Part 4: Determination of theoretical energy consumption of electric wheelchairs and electric scooters;

--- Part 5: Determination of dimensions, mass and operating space;

--- Part 6: Determination of the maximum speed, acceleration and deceleration of electric wheelchairs;

--- Part 7: Measurement of seat and wheel dimensions;

--- Part 8: Requirements and test methods for static strength, impact strength and fatigue strength;

--- Part 9: Electric wheelchair climatic test method;

--- Part 10: Determination of the obstacle-surmounting ability of electric wheelchairs;

--- Part 11: Test dummies;

--- Part 13: Determination of the coefficient of friction of the test surface;

--- Part 14: Requirements and test methods for power and control systems for electric wheelchairs and electric scooters;

--- Part 15: Requirements for information release, document issuance and identification;

--- Part 16: Flame retardancy of postural fixation devices;

--- Part 19: Wheeled mobile devices that can be used as motor vehicle seats;

--- Part 21: Electromagnetic compatibility requirements and test methods for electric wheelchairs, electric scooters and battery chargers;

--- Part 22: Adjustment procedures;

--- Part 25: Batteries and chargers for electric wheelchairs;

--- Part 26: Terminology;

--- Part 28: Requirements and test methods for stair climbing appliances;

--- Part 30: Wheelchair test methods and requirements for changing the occupant's posture:

Among them, Part 26 is the term; Part 11, Part 13 stipulates the infrastructure requirements for wheelchair testing; Part 22 stipulates

Sets test preparation requirements; Part 15 sets out information release requirements; Parts 1, 3, 5, 7, 8

Part, Part 10, Part 16 specifies the general requirements and test methods for all wheelchairs (including manual and electric); Part 2,

Part 4, Part 6, Part 9, Part 14, Part 21, Part 25 set out the requirements and

Test methods; Parts 19, 28, and 30 specify requirements for special functional wheelchairs:

The driving distance of an electric wheelchair is affected by energy consumption and battery status: Energy consumption is affected by many factors, such as ambient temperature, total weight and weight

volume distribution, terrain, road surface and tires: Batteries are affected by certain factors, such as temperature, age, number of charges and discharges: therefore,

The test results made in accordance with the provisions of this document cannot be used as a basis for deriving the exact actual driving distance of a specific wheelchair and user: Of course

However, the results of this test can be used as a basis for comparisons between different wheelchairs under similar test conditions:

The driving style of the wheelchair also affects the driving distance, and the singleness of the theoretical distance cannot fully reflect the performance of the wheelchair: This article

The article provides two methods of electric wheelchair and electric scooter to measure theoretical distance: These values are for ease of use on wheelchairs and known machines

Compare the fuel consumption of motor vehicles:

Determination of theoretical energy consumption of electric scooter

1 Scope

This document describes a method for measuring the theoretical driving distance of electric wheelchairs (including electric mobility scooters), i:e: measuring the energy

consumption and the rated battery capacity of the wheelchair battery:

This method is applicable for indoor and outdoor movement with a maximum speed of 15km/h and a specified occupant mass within the scope of ISO 7176-11:

moving electric wheelchairs: This document requires the inclusion of inspection reports and information releases:

4 Principles

Measure energy consumption for two driving methods: continuous driving and handling: Continuous driving refers to driving the wheelchair in a clockwise direction along the test track:

Drive 10 laps and 10 laps counterclockwise to measure the energy consumption: Manipulation refers to the reciprocating movement of the wheelchair between two marked points 5m apart:

Stop and steer outside the marked points and measure the energy consumption for 10 laps in each direction: The theoretical range value is calculated by energy consumption, rated driving distance
