Overview

ISO 7176-25:2022 - "Wheelchairs - Part 25: Lead‑acid batteries and chargers for powered wheelchairs - Requirements and test methods" defines performance, safety and testing requirements for lead‑acid batteries and battery chargers used with electrically powered wheelchairs and scooters. The standard applies to chargers with a rated input voltage ≤ 250 V AC and a nominal output voltage ≤ 36 V. This second edition (2022) updates the 2013 version and clarifies requirements for chargers, battery safety, test reports and user documentation.

Key Topics and Requirements

Scope & definitions: Terms such as battery, lead‑acid battery, nominal voltage, rated input/output and cyclic endurance are defined to ensure consistent testing and specification.

Test conditions: Standard test environment is 20 °C ± 5 °C. Measurement equipment requirements include a mean current meter with 2% accuracy and voltage-drop not exceeding 0.2% of nominal battery voltage, plus an r.m.s. current meter with similar accuracy.

Battery chargers:

Electrical safety and performance-related safety requirements (general safety, charging connector design, reverse‑polarity protection, charging of faulty battery sets).
Charging capability: defined tests and preparation procedures to verify charger performance.
EMC (electromagnetic compatibility) requirements and test methods.
Indicators: visual/operational indicators and test methods to confirm proper feedback to users.

Batteries:

Performance requirements including charge retention and cyclic endurance testing.
Safety requirements, marking and documentation.

Documentation & reporting: Clauses define required contents of test reports and user manuals for both chargers and batteries.

Risk & safety note: The standard warns that some test procedures can be hazardous and require appropriate safety measures.

Practical Applications and Users

ISO 7176-25:2022 is used by:

Manufacturers and designers of powered wheelchairs, scooters, lead‑acid batteries and chargers - to design products that meet safety and compatibility expectations.

Test laboratories and conformity assessment bodies - to perform standardized performance and safety testing.

Procurement officers, clinics and rehabilitation services - to specify compliant batteries/chargers for acquisition and maintenance.

Regulatory and certification organizations - to reference accepted test methods and reporting requirements.

Benefits include improved reliability, safer charging systems (on‑board, carry‑on and off‑board chargers), clearer product documentation, and assurance of compatibility between wheelchairs, batteries and chargers.

Related Standards

Key referenced standards include IEC/ISO electrical safety and battery standards such as:

ISO 7176 series (e.g., ISO 7176‑8, ISO 7176‑21, ISO 7176‑26)

IEC 60335‑2‑29 (battery charger safety)

IEC 60254 (lead‑acid traction battery tests)

IEC 60529 (IP Code) These related standards support testing for mechanical strength, EMC and broader battery safety.
