A Study on the Reliability Test of a Lithium Battery in Medical Electric Wheelchairs for Vulnerable Drivers

Abstract

There are test items for lithium-ion batteries in reliability testing for automobiles and motorcycles, but equivalent test items have not yet been established for mobility scooters (also known as electronic wheelchairs). To evaluate the lithium-ion battery pack or system mounted on a mobility scooter, it is necessary to test vibrations and mechanical shock while driving, independent of tests for the lithium-ion battery cells. In an effort to meet this need, test profiles were established for mobility scooter lithium-ion batteries by performing on-road driving tests and mechanical shock tests. The proposed test profiles were validated using robust statistics and proficiency statistics. The safety of the test profiles was tested in a nationally accredited testing laboratory. As a result, the lithium-ion battery mounted on the mobility scooter was found to have incurred no leakage, short circuit, burst, or explosion. The vibration and mechanical shock test profiles proposed in this study are expected to serve as basis data for establishing standards for mobility scooter safety and reliability.

Smart Wheelchair Controlled Through a Vision-Based Autonomous System

“…Therefore, we have studied different kind of wheelchairs before implementing our project [31]- [33]. A manual wheelchair is a freely moving device in which the patient sits.…”

“…With traditional joystick-controlled wheelchairs, users must have sufficient upper body strength and dexterity to operate the joystick effectively [12]- [15]. However, with a vision-based autonomous wheelchair, users can navigate the environment with minimal physical effort [18], [21], [31]. 4) The system can adapt itself based on the user's preferences and abilities.…”

“…[19], [20], [21] El tema de las baterías eléctricas también está presente en muchos artículos, se observan publicaciones de cómo estas han evolucionado mucho en los últimos años y en cómo se debe disponer de ellas o su reutilización. [22], [23], [24] Otro de los temas encontrados en las publicaciones del área de ingeniería es el balanceo de sistemas de uso compartido, algunos de ellos hablan de Scooters y bicicletas aparte, pero algunos los mezclan según el uso de los mismos en las ciudades y su importancia en el transporte de última milla. [2], [25], [26] Un tema importante en la ingeniería de tránsito es el cambio modal, como pasar de un medio de transporte al otro y se encuentran publicaciones que tratan de determinar este tipo de cambios ya sea pasar del automóvil a la patineta o a la bicicleta eléctrica.…”
