This is done by feeding the higher input voltage into the primary side of the transformer and the lower output voltage is produced on the secondary side of the transformer. The primary of the transformer consists of at least two inputs (or taps) and may contain several more. Each input tap is designed to produce a calculated voltage on the output windings called a secondary. Various switches are employed to change these taps in order to get the desired output levels and timers are often used to govern the length of time on charge. The lower secondary voltage of the transformer is then connected to the rectifier (or diodes) which clip the top half of the AC (alternating current) sine wave resulting in DC (direct current) voltage. This is the voltage used to actually charge the battery.

For beginners, we suggest alkaline batteries, such as the venerable AA or 9V cell, great for making into larger multi-battery packs, easy to find and carry plenty of charge. If you want to go rechargable to save money and avoid waste, NiMH batteries can often replace alkalines. Eventually, however you may want to upgrade to the shiniest new technology - rechargable lithium ion/polymer batteries. © Adafruit Industries https://learn.adafruit.com/li-ion-and-lipoly-batteries Page 3 of 20 Rechargeable Lithium Names There are nearly a dozen different chemistries of rechargable lithium ion batteries but we will be specifically talking about Lithium Ion and Lithium Ion Polymer as a group. On the left you can see two Lithium Ion Polymer cells. On the right, two packs made of cylindrical Lithium Ion batteries Lithium Ion cells tend to be either rectangular or cylindrial. They are hard-shelled with a strong casing. They often weigh a little more and come in larger capacity but they are also more sturdy and are hard to puncture.

In each category, a general description about the principle and direction of development is given. Both the metal hydride (MH) alloy and nickel hydroxide as active materials in negative and positive electrodes, respectively, are reviewed extensively. Both thermal and battery management systems (BMSs) are also discussed. Keywords: metal hydride (MH); nickel/metal hydride (Ni/MH) battery; nickel hydride; electrode fabrication; U.S. patent 1. Introduction The nickel/metal hydride (Ni/MH) battery is an essential electrochemical device for consumer, propulsion, and stationary energy storages. Since its commercial debut in the late 1980s, many researchers have worked diligently in the Ni/MH battery field. Their contributions were publicized through two routes: academic publications and patent applications.
