The advancement in Electric Vehicles, Drone and other mobile electronics like IoT Devices seems to be promising for the future. One common thing among all these is that they are all powered by batteries. Following Moore’s law the electronic devices tend to become smaller and more potable, these portable devices should have their own source of power to operate. The most common battery choice for portable electronics today is Lithium Ion or Lithium Polymer Batteries. While these Batteries have a very good charge density they are chemically unstable under harsh conditions hence care should be taken while charging them and using them.

In electronics, a regulator is a device or mechanism which can regulate the power output constantly. There are different kinds of regulators available in the power supply domain. But mainly, in the case of DC to DC conversion, there are two types of regulators available: Linear or Switching.

What are Cell Balancing Techniques and How to Use Them?
When four cells are connected in series the voltage values of all the four cells should be equal to derive the battery pack with maximum efficiency. The method of maintaining all the cell voltages to be equal is called as cell balancing. In this article we will learn more about cell balancing and also briefly about how to use them on the hardware and software level.

To cope up with the voltage and current demand EV manufacturers have to combine hundreds if not thousands of cells together to form a Battery Pack for a single car. To give an idea the Tesla model S has about 7,104 cells and the Nissan leaf has about 600 cells. This large number along with the unstable nature of Lithium cells makes it difficult to design a Battery Pack for an Electric Car. In this article let us explore how an Electric Vehicle Battery Pack is designed for an EV and what are the vital parameters associated with batteries that has to be taken care of.

A Voltage or Potential Divider Circuit is commonly used circuit in electronics where an input voltage has to be converted to another voltage lower than then the original. This is very useful for all analog circuits where variable voltages are required, hence it is important to understand how this circuit works and how to calculate the values of the resistors required to make a voltage divider circuit to output the desired voltage.
In this project we convert 220V AC supply in to +12V and -12v DC supply, that is why it is named Dual Power Supply as we get positive and negative 12v power supply at the same time.
