Solar electric ambulance van to assist rural emergencies of Bangladesh- a complete off-grid solution

Abstract

Rickshaws are an essential method of transportation in Bangladesh. When it was altered to electrically assisted rickshaw, it attained popularity but was soon discontinued due to over consumption of power. Therefore, Control and Applications Research Centre (CARC), BRAC University has proposed the concept to give a complete off-grid arrangement by utilizing the PV array, torque sensor pedal, and solar battery charging station and implementing it in a solar electric ambulance van as a significant part of individuals who live in the provincial zones, where the likelihood of reaching the hospital on time is very low due to lack of mode of transportation. The torque sensor pedal lessens the over-utilization of battery-bank. The intelligent control framework reduces the human force and diminishes the over-utilization of engine. PV panel is introduced on top of the van to share a part of the power and a solar battery charging station is installed to make the entire framework totally autonomous of national grid. This paper consists of the design and implementation of the idea proposed by CARC.
