    Rickshaws are a key mode of transportation in Bangladesh. When it was changed to electrically-assisted ones, it achieved prevalence but was soon banned because of overconsumption of power from the national grid. In determination, Control and Applications Research Centre (CARC), BRAC University has proposed the idea to give a complete off grid course of action by using the PV array, torque sensor pedal and solar battery charging station. Since a significant number of people live in the rural areas, the probability of reaching the hospitals in the towns is low because of absence of proper mode of transportation. The torque sensor pedal decreases the over-usage of battery-bank. The control structure lessens the human effort and curtails over-usage of motor. 400W PV panel share power with the battery bank and the solar battery charging station completely detaches itself from the national grid. Previous model called 'The Human Hauler' implemented these techniques but our modifications made the entire system more efficient. We have achieved up to 25% increase in total distance travelled and 37% increase in speed. Further modifications to chassis with five wheels made the vehicle stable. This paper comprises of the configuration and usage of the thought proposed via CARC.

    Real-time monitoring of Solar Battery Charging Station
    (© 2016 IEEE, 8/31/2016) Priyanka, Mirza Karishma; Chowdhury, Abrar Alvi; Mahmud, Bushra; Chowdhury, Sheri Jahan; Azad, Akm M.M.Abdul Malek
    This paper represents a real-time monitoring technique of all the components of a Solar Battery Charging Station (SBCS). Its ability to generate clean energy at free of cost, along with availability almost all year round makes SBCS very popular in tropical countries like Bangladesh. Successful implementation of this technique in any existing SBCS can increase its efficiency and distribute more power to rural areas where National Grid is unavailable. The purpose of our project is to monitor every available aspect in any existing SBCS so that manual labor of any kind would not be required. In order to do so, we have created a new software for Windows operating system to monitor the battery voltages, SOC, approximate time remaining to become fully charged as well as each individual panel status and overall solar voltage and solar current, along with a manual backup system in case of low solar radiation. To take readings, we used a Data Acquisition (DAQ) Card and interfaced it with our software in a computer, so that we can take the most out of our available resources and give reliable readings in real time.
