DESIGN AND CONSTRUCTION OF A BATTERY CHARGER

CHAPTER ONE INTRODUCTION

1. BATTERY CHARGER

Battery charger is a device that charges or recharges or current back through lead – acid cell, Alkaline cell, carbon zinc cell and nicad batteries, reversing chemical action of discharging of the battery.

 In 1968 Makita Charles invented Battery charger called Makita charger. This specified for cordless tool like above batteries. This charger was designed to provide rapid recovery time, vital for quick recharge. It has frequent starts and stops. He achieved this when he integrated the following electrical and electronics parts together: Transformer, Diodes, Resistors, capacitor, wire and integrated circuit all connected on the veroboard and cased with electric conducting material. Including other peripherals that made the device heavy and costly.

In 1972 Saitek Smart invented Battery charger called Saitek Smart charger. This was regarded as the fastest model on the market, the smart charger is for smart charging. Smart charger is specifically designed to deliver ultra fast charging, conditioning and checking with a large liquid crystal display (LCD) panel that keeps users fully informed of charging status and batter condition. The Smart charger’s logic recognized battery types and monitors the charging process. Bad batteries are automatically rejected. Easy to use. Just insert batteries and close the lid. The above qualities make Saitek smart charger the model battery charger in the market. It costs U.S. $79.95 which rates N7595.25 in Nigeria.
