Automatic battery charging system on android smartphones

A smartphone needs a battery source to work well. During the battery charging process, the state of charge can be increased by up to 100%. One habit of charging batteries is to leave the smartphone connected to the charger all night long. Batteries that are already 100% but still connected to the charger will continue to receive an electric current even though a small value can cause a decrease in battery life and durability. This final project aims to create an automatic battery charging system based on the Android operating system. The result of this system is when the percentage limit that we have set is the same as the percentage of the battery on the smartphone, the system will automatically cut off the incoming current so that the charging process will stop. This system is designed using a microcontroller, Bluetooth module, relay module, Android apps, and smartphone with an Android operating system. The tests are the suitability of the apps with the smartphone, the charging and discharging conditions on the system, and automatic battery charging. From the results of the tests, the system can cut the current to a value of 0 amperes from the charger manually and automatically controlled through the apps, the apps can be used on smartphones that have Android version 2.1 or higher.

Performance of a speed bump piezoelectric energy harvester for an automatic cellphone charging system

We propose a piezoelectric energy harvesting technology installed in a roadway speed bump. We have installed a module that can charge mobile phones utilizing a speed bump piezoelectric harvester (SBPH), which is easy to apply to roads. A highly integrated module with 40 piezo-generators was fixed and installed at the center of the speed bump. When a medium-sized vehicle passed the module at a speed of 30 km/h, an output voltage of 144 Vmax, output current of 45.2 mAmax, and output power of 4086.08 mWmax (6.81 W/m2) were measured at a load resistance of 2 kΩ. When the vehicle passed over the SBPH nine times, it charged a capacitor (10,000 μF) to provide 6 V for about 200 s, and the charged electrical energy was enough to operate a cellphone. The self-controlled battery charging system via electricity generated by the piezoelectric module could be applied to a speed bump installed on an actual road.

Design of a Fuel Free Electric Vehicle Using Fuzzy Logic for Pollution Control

Nowadays the existing vehicles, which run through fuel, are produces excess pollution. To avoid this problem we proposed a new method called Fuzzy based Electric Vehicle (FEV) without using fuel. An advanced battery system and drive is integrated through fuzzy controller. The design of automatic charging system meets different design parameters and automatically starts and stops the charging system, eliminating the need for driver involvement. The proposed system contains two turbines with an alternator, one for charging the auxiliary battery and the other one for two purposes: for charging the HV battery system and drive the motor directly if the speed exceeds forty kilometers. The power generation system is present in the top of the vehicle. Compared with other vehicle technology, the FEV presented in this paper overcome the future fuel crisis. Simulation result shows that the electric vehicles eliminate total diesel exhaust and help for healthy generation.

A non-contact energy transferring system for an electric vehicle-charging system based on recycled products

A non-contact automatic charging system for electric vehicle application is presented. The principle is the same as that of the transformer where the primary and the secondary circuits are separable but coupled with each other without using the hand coupler. In this paper, we present a possibility of removing the core of the secondary coil on the body for reducing the weight of the car. In our experiments, the primary core, which is placed on the earth floor, is made of Mn–Zn ferrite with square shape as 1m×1m×10mm for a large cross-sectional area. The steel floor of the car assists to pass the magnetic flux. An efficiency rate over 90% with the test device of 2kW is obtained without the conventional secondary core. The leakage inductance is well compensated by a resonance capacitor inserted in the secondary coil. In this experiment, the distance between the primary and the secondary coil is 100mm and the switching frequency is 100kHz. In addition, we developed a pavement method for the system. The method utilizes plates made from the waste of expanded polystyrene and rubber mats made from used tire. The plates are set up on the rubber mats and these mats are arranged over the non-contact charging system. The pavements can be replaced easily when the system is exchanged. Therefore, this pavement method is not only practical for the non-contact charging system but is also useful for recycling of resources and reduction of waste matters.

Energy from straw—A comparison of some straw-burning furnaces

Since 1974 research has been carried out in Weihenstephan on the production of energy from cereal straw. First the fuel straw was characterised by determining its calorific value, taking into consideration moisture content, storage conditions, species, varieties, growth conditions and fertilisation. Other characteristics of the straw—such as percentage of volatiles and chemical elements, demand for combustion air and specific fuel gas volume—were determined. Measurements were made with serial-furnaces (mainly the throughburning type). These furnaces were developed in order to increase efficiency and decrease emission. Automatic stoking systems had to be tested. Test runs were also carried out on prototype furnaces with both under-burner systems and hand stoking. A special under-burning furnace with a low capacity automatic charging system (for heating a domestic dwelling) had been developed in Weihenstephan. Different types of air heater, using both high pressure bales and roto bales, were constructed. Economic calculations show that straw is a cheap fuel under certain conditions. An EEC study shows the energy demand and energy production potential of straw and woodwaste in various rural areas.
