What is inside a battery of an EV?
A cathode, anode, and electrolyte that serves as a catalyst make up an electrochemical battery. A battery pack made up of several cells combines and arranged in a certain way is an EV battery.
How does the battery work?
When charging, a positive charge buildup occurs at the cathode/electrolyte interface. This causes electrons to flow toward the cathode. This results in the formation of a voltage potential between the cathode and the anode. A passing current from the positive cathode to an external load and back to the negative anode causes the release. When charged, current flows in the opposite direction.
What is an EV battery?
An EV battery is a rechargeable battery that powers an electric vehicle. A lithium-ion battery is the most common type of EV battery.
What’s inside an EV battery pack?
A battery pack is a component that stores electrical energy to power an appliance. For example, an energy storage system (ESS) or an electric vehicle (EV). Cells that are all connected to one another, stores energy.
For a battery pack to gain traction with consumers, it must compete with fuel engines. This presents a significant challenge because electric batteries must overcome complex issues that internal combustion engines (ICE) do not have.
- Each cell consists of two electrodes (an anode and a cathode) separated by an electrolyte. On charging, the anode releases lithium ions into the electrolyte. On discharge, the lithium ions travel back to the anode.
- The number of cells and the size of the battery determine the total capacity of the battery. EV batteries generally range from about 15 to 100 kWh of capacity. It can last up to a few hundred thousand miles before needing to be replaced.

Other components in the EV battery:
Inside an EV battery, there are also other components such as a Battery Management System (BMS), a cooling system, and an electrical system.
- The BMS monitors and regulates the battery’s performance, such as voltage, current, and temperature.
- The cooling system helps to keep the battery at the right temperature. The electrical system helps to deliver power to the electric motor.
- Several modules combine to form EV batteries. Each module contains a number of cells. The number of cells in each module can vary depending on the type of vehicle and the manufacturer.
- Each cell has a positive and negative terminal and a separator in between to keep the cells from discharging and overcharging. The cells are usually grouped together into a larger unit. The modules are then connected together and this forms the entire battery.
The components of battery are designed to work together. They provide the necessary power to run an EV. While the technology behind EV batteries is constantly evolving, the basic components remain the same. An EV battery can last for several years with proper maintenance.
