The main components include the cathode, anode, electrolyte, and separator. The cathode and anode are where the lithium ions hang out, the electrolyte is a liquid that helps the ions move, and the separator keeps everything from short-circuiting. The voltage and capacity of the EV battery are what determine how much power the vehicle can deliver and how far it can travel on a single charge. The design and layout can vary, but the main goal is always to safely store and release a lot of energy. This directly impacts the range, performance, and overall driving experience of an electric vehicle. They are a complex system of interconnected components, all working in harmony to provide power to the electric motor. The batteries are designed to handle thousands of charge and discharge cycles, but like all technology, they do degrade over time.

Now, how does this magic actually work? When you plug in your EV, the electricity flows into the battery, and a chemical reaction stores the energy. When you hit the accelerator, the stored energy is released, and the chemical reaction reverses, providing power to the motor. Clever, right? The battery management system, or BMS, is the brains of the operation. It monitors the battery's health, regulates charging and discharging, and protects it from damage. The BMS ensures the battery operates safely and efficiently. The performance characteristics of EV batteries, such as energy density and charging speed, are constantly improving. Over time the EV battery's capacity will decrease, a phenomenon known as degradation.
