What are the classifications of electric vehicle batteries?

[SanThomas]

Electric vehicle batteries are classified into storage batteries and fuel cells. Storage batteries are suitable for pure electric vehicles, including lead-acid batteries, nickel-metal hydride batteries, sodium-sulfur batteries, secondary lithium batteries, air batteries, and ternary lithium batteries. Fuel cells are used for fuel cell electric vehicles, including alkaline fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells, solid oxide fuel cells, proton exchange membrane fuel cells, and direct methanol fuel cells. The performance parameters of electric vehicle batteries are: 1. Electromotive force: Also known as the standard voltage or theoretical voltage of the battery, it is the potential difference between the positive and negative poles when the battery is open-circuited; 2. Rated voltage: Refers to the recognized standard voltage of the electrochemical system when the battery is operating; 3. Open-circuit voltage: The battery voltage under no-load conditions.
