Electromagnetic compatibility in Electric Vehicles

When current passes through a conductor it creates electromagnetic fields and almost all electronic devices like TVs, washing machines, induction stove, traffic lights, mobile phones, ATMs and laptops etc., will emit the electromagnetic fields. Fossil fueled vehicles also suffer from Electromagnetic Interference (EMI) – The ignition system, starter motor and switches cause broadband EMI and electronic devices cause narrowband EMI. But as compare to ICE (Internal Combustion Engine) vehicles, Electric Vehicles are combination of various subsystems and electronic components like battery, BMS, DC-DC converter, inverter, electric motor, high-power cables distributed around the vehicle and chargers, all these are working at high power and frequency levels which causes the emission of  high-level low-frequency EMI.

How Regenerative Braking Works in Electric Vehicles

Engineers came up with the regenerative braking system to recover the kinetic energy dissipated as heat during braking in the traditional braking method. Going by the laws of physics, we cannot recover all of the kinetic energy that is lost but still significant amount of kinetic energy can be converted and stored in battery or Supercapacitor.

Multicell Voltage Monitoring for Lithium Battery Pack in Electric Vehicles

The mileage and performance of an Electric Vehicle depends on the capacity and efficiency of its Battery Pack. To maintain the battery pack in full health is the responsibility of the Battery Management System (BMS). A BMS is a sophisticated unit in an EV which does a lot of activity like monitoring the cells, balancing them and even protecting them from temperature changes.

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.

All you want to know about Electric Vehicle Batteries

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.
