Given a case in the UK in 2024 where
improper use of lithium battery chargers for electric wheelchair products resulted
in a fatal accident,
customers of UK manufacturers involved in electric wheelchairs and mobility scooter-related products have recently received notification emails from the UK MHRA Vigilance Group, in which the MHRA has advised all manufacturers of electric wheelchairs/mobility scooters that use lithium batteries in their devices to implement additional safety features in order to prevent future fatalities or injuries caused by lithium battery fires.
In the letter, the MHRA has recommended
that relevant manufacturers complete the following safety improvements:
1、It is recommended that manufacturers add
additional warning labels to the batteries and chargers, clearly stating the fire hazard or other
warnings regarding the use of unauthorized battery chargers;
2、Manufacturers are advised to reassess the
safety and performance of their lithium battery-powered devices by ensuring
compliance with the latest requirements outlined in the "BS ISO
7176-31:2023" standard for electric wheelchairs and mobility scooters. The
standard, which covers lithium-ion battery systems and chargers, includes
detailed safety requirements and testing methods to ensure reliable device
performance. For further reference, the relevant standards can be found at: https://www.bhta.com/lithium-battery-safety-guidance/
We urge all involved manufacturers to take
this matter seriously and implement the necessary measures to proactively comply
with the UK MHRA’s requirements.
