DEV (Difabel Electric Vehicle) for wheelchair user

Mobility for wheelchair users remains constrained by inadequate assistive technologies and infrastructure, limiting independence and quality of life. This study presents the development of a three-wheeled electric vehicle tailored for wheelchair users, featuring an integrated foldable rear ramp (10–15° incline), a secure wheelchair locking system, and ergonomically positioned handrails for balance support. The vehicle uses a 72 V, 3 kW BLDC hub motor powered by a 72 V, 40 Ah lithium-ion battery, supported by dual braking systems and a Battery Management System (BMS). Tests showed safe operation on slopes up to 15°, a top speed of 38–40 km/h, and a range of approximately 90 km per charge and boarding time was under 60 seconds. User feedback reported high satisfaction in comfort, control, and safety. The vehicle demonstrates strong potential as an inclusive mobility solution for urban environments.
