Full title and description

ISO 16090-1:2022 (adopted as St ISO 16090-1-2022 in 2023) — Wheelchairs — Determination of the performance of electric wheelchairs — Part 1: Energy consumption and range

Abstract

This document specifies laboratory test methods for determining energy consumption and range of electric wheelchairs under defined conditions. It provides standardized procedures for measuring battery energy use, calculating driving range, and reporting results so manufacturers, test laboratories and purchasers can compare products consistently. The methods address steady-state and representative drive cycles, test setup, instrumentation, environmental conditions and data analysis.

Scope

Specifies test procedures to determine the energy consumption and range of electrically powered wheelchairs under controlled laboratory conditions. The standard applies to a variety of electrically powered wheelchair types intended for individual use and covers preparation of the wheelchair and battery, test tracks or dynamometer use, environmental control, definition of drive cycles and calculation methods to report energy consumption and estimated driving range.

Key topics and requirements

• Definition of test conditions and environmental parameters for repeatable measurements.
• Test setup including instrumentation, battery conditioning, payload and wheelchair configuration.
• Representative drive cycles and steady-state tests to measure energy use.
• Methods to calculate energy consumption per unit distance and to estimate maximum driving range.
• Reporting requirements: test results, test conditions, uncertainty and limitations.
• Safety and handling instructions for batteries during testing.

Typical use and users

Used by wheelchair manufacturers, component suppliers, independent test laboratories, regulatory bodies and procurement agencies to characterize and compare the energy performance and expected range of electric wheelchairs. Also useful for research institutions and consumer organizations evaluating battery life and range claims.

Related standards
