EMC stands for Electromagnetic compatibility, which means that a device is compatible with (i.e., no interference is caused by) its electromagnetic (EM) environment. It does not emit levels of EM energy that generate electromagnetic interference (EMI) in other devices in the vicinity. Electromagnetic interference (EMI) is the interference caused by one electrical or electronic device…
What are EMS/EMC immunity lab tests?
EMC test is known as Electromagnetic Compatibility, a certification for electronic devices to maintain their limitation of electromagnetic waves. As discussed in the previous article, there are two types of EMC tests – emission (EMI) and immunity (EMS). EMI (Electromagnetic Interference) tests measure the magnetic waves emitted by the device, and EMS (Electromagnetic Susceptibility) tests…
What are some common EMI/EMC tests?
An EMC test is known as Electromagnetic compatibility, a certification for electronic devices to maintain their limitation of electromagnetic waves. As discussed in the previous article, there are two types of EMC tests: emission (EMI) and immunity (EMS). EMI (Electromagnetic Interference) tests measure the magnetic waves emitted by the device, and EMS (Electromagnetic Susceptibility) tests…
How to perform an EMI/EMC pre-compliance test
EMC testing is essential to get a certification of Electromagnetic Emission and Immunity test before launching the product in the market. However, actual EMC tests are pretty expensive. Before going for the actual EMC test, the product should test in EMC pre-compliance test Lab. Pre-compliance testing will mimic all tests performed at EMI/EMC test labs…
EMS/EMC Pre-Compliance immunity test
In the previous article, we learned about EMI/EMC pre-compliance test. EMS/EMC pre-compliance immunity test is required before the compliance test. EMS/EMC pre-compliance immunity test will give the confidence to pass the compliance test. The pre-compliance immunity test simulates all the tests done at the compliance test lab, but it is unnecessary to apply all the…
Battery configurations (series and parallel) and their protections
A single cell is not sufficient for some devices. To achieve desired voltage, the cells are connected in series to add the voltage of cells. To achieve the desired capacity, the cells are connected in parallel to get high capacity by adding ampere-hour (Ah). This combination of cells is called a battery. Sometimes battery packs…
Introduction to batteries and their types
What is a Battery? A battery is an electrochemical device that can store energy in the form of chemical energy. It translates to electric energy when the battery is connected in a circuit due to the flow of electrons because of the specific placement of chemicals. It was invented by Alessandro Volta, whereas Gaston Plante…
What are the different battery types for specific applications?
In this article, we will learn how to choose a battery according to the specifications and requirements of your application. Some applications need more power and some need to be cheap with less power. There are various factors and parameters that to consider when choosing the best battery for your application. No one battery is…
Understanding battery management systems
A battery-management system (BMS) is an electronic system or circuit that monitors the charging, discharging, temperature, and other factors influencing the state of a battery or battery pack. It’s used to monitor and maintain the health and capacity of a battery. Today’s BMS devices are advanced and will often provide pop-up notifications as you’ve likely…
How rechargeable batteries, charging, and discharging cycles work
The battery stores electrical energy in form of chemical energy and the chemical energy again able to convert into electrical energy. The conversion of chemical energy to electrical energy is called discharging. The chemical reaction during discharge makes electrons flow through the external load connected at the terminals which causes the current flow in the…
