Hundreds of millions of these products are sold annually to businesses and consumers, with close to a billion in U.S and Nigeria. While designers of battery chargers often maximize the energy efficiency of their devices to ensure long operation times between charging. ABSTRACT This project presents the design and construction of a battery charger. Our primary objective is to assist and guide final year students with well researched and quality project topics, project works, research guides, and project materials, at a very reduced and affordable price. The organization of the project report is well detailed and vast in its coverage. Rechargeable batteries store electricity from theutilitygrid for later use and can be conveniently recharged when their energy has been drained. This type of device is important because there are many rechargeable devices that use 12 or 24v battery. Such a charger would supply currents in excess of safe values, would not turn off automatically when battery voltage exceeds safe limits, and would continue unchecked until the battery was damaged.In order to achieve ten times extension of the normal life of an everyday alkaline battery, you will have to recharge it frequently, many more times than ten.

This project, 12v battery charge consist of few chapters, deal extensively with the design and construction of a batter charge which is capable of charging a 12v battery. The system testing was first carried out accordingly in a laboratory setting. Christine T. Bryant, (1990) say not all chargers can recharge alkaline batteries. In this project, a sophisticated class of battery charger is designed not just to refill rechargeable batteries but to conserve the battery life because wrong handling and charging of a battery can permanently damage the battery even if is brand new. This also assumes that the battery is 100% efficient at absorbing the charge. Used a s olar panel of 12 volt and an Op-Amp as a shunt re gulator to construct a 12 volt battery solar charger. Experimental results indicate that there is an increase of the overall charging current when fully charging an empty: mobile phone battery and a 6v rechargeable lamp for 4 hours using direct charging between 10.00am to 4.00pm. Batteries that are not recharged before use will not supply the full amount of stored energy. Very rapid charging rates, 1 hour or less, generally require the charger to carefully monitor battery parameters such as terminal voltage and temperature to prevent overcharging and damage to the cells. We understand the Time Factor, & we have simplified the process so that you can get your projects instantly. It is not advisable to use it on rechargeable batteries above 12V. As with any charger it must be housed in a clean environment and operations should be by will trained individual. They often ignore how much energy is consumed in the process of converting ac electricity from the utility grid into dc electricity stored in the battery. Account Type: Savings We could save a lot of electric power using new electronic technology in our charging system and then highlight several design strategies for improving the efficiency of other chargers. It may, however, require an external capacitorto be connected across its output terminals in order to smooth the voltage sufficiently, which may be thought of as a DC voltage plus a ripple voltage added to it. 4.2iv Voltage Control and Monition Unit 9 offers from $37.61.

If you read the warning labels printed on ordinary batteries, you will observe that a NiCad charger shouldneverbe used on alkaline batteries. In this project design, significant energy savings are possible by reducing the conversion losses associated with charging batteries in battery-powered products. The major aim and objective of this project is to design and construct a battery charger that can be use to charge any kind of 12v rechargeable batteries including alkaline, NiCad or lead acid batteries. The introductory chapter goes a long why in defining the battery charger and explanations of the mode of operations will be death with as we proceed. A trickle charger provides a relatively small amount of current, only enough to counteract self-discharge of a battery that is idle for a long time. It acts as a control circuit to monitor and regulate the process of charging several batteries ranging from 4 volts to 12 volts, using a photovoltaic (PV) solar panel as the input source for the battery charging process. Managing their own batteries is fun, and they know it helps the environment by not having to throw batteries away when they can recycle them. We had to destroy many electronic devices for solution. None of the above happens with common alkaline batteries. A battery charger is an indispensible device for battery users because battery is an essential element that powers any electronic products like UPS inverters system,photographic equipments, hand-held lamps (flashlight or torch), computer-memory standby, toys, noveltiesand automobiles, etc. Also there is nointernal resistance connected in the battery charger to limit the short circuit current. This unregulated DC voltage is fed directly to the DC load (in this case, the battery) via a relay. This project (device) offers a better alternative to Public Power Supply, Generators as well as UPS considering it is cost effective, noiseless and easy maintainability.
