What is battery charger? Battery charger can be defined as the electronic device that is used to recharge the battery by forcing passage of electrical current into the battery.
Types of Battery Chargers The battery chargers can be divided into many types. These types can be categorized as follows: 1. 2. 3. 4. 5.
Simple Charger Fast Charger Inductive Charger Motion Powered Charger Solar Charger
Simple Charger • This type of charger works by supplying a constant direct current to the battery that is being charged. • This charger does not have the ability to cut out the supply when the charging is complete. • The simple charger is very inexpensive and it really takes a longer time to charge the battery but this delay in time prevents a battery from overcharging. • There is also one disadvantage of charging the battery with a simple charger for too long will weaken the battery. • The simple AC powered battery chargers are said to have high ripple voltage and current. • Life of a AC simple charger is within 3% of the life of a constant DC battery charger.
Fast Charger As the name suggests these charges charge the battery at a faster rate as compared to the simple charger. Most of these chargers have a cooling fan installed on them so that it keeps the temperature of the cell under control. Many of the fast chargers have the ability to act as standard overnight charges when they are used with the standard NiMH cells.
Inductive Charger • This type of charger uses the electromagnetic induction to do the process of charging. • In these charges, there is a charging station that sends the electromagnetic energy with the help of an inductive coupling to the device which in turn stores the energy in the battery. • This whole process is achieved without the testing of metal between the battery and the charger. This charger is commonly used to charge electric toothbrushes.
Motion Powered Charger This type of charger charges the battery by using the human motion. Tremont electric is the company that has made a charger which consist of magnet held between two elastic springs and the charging done at the device is moved up and down like during the process of walk.
Solar Chargers •These are just having the ability to convert the light energy into direct current. • The main advantage of this charger is that they are portable but that can also be fixed. •These fixed chargers are known as solar panels.
