What kind of batteries do electric vehicles use?
1 Answers
Electric vehicles use storage batteries and fuel cells. Introduction to storage batteries: A device that converts chemical energy into electrical energy is called a chemical battery, commonly referred to as a battery. After discharging, it can regenerate the internal active material through charging—storing electrical energy as chemical energy; when discharging is needed, the chemical energy is converted back into electrical energy. Such batteries are called storage batteries (Storage-Battery), also known as secondary batteries or lead-acid batteries. The relationship between the internal resistance of a storage battery and its state of charge (SOC): The state of charge (SOC) of a storage battery refers to the ratio of the capacity that can be discharged to its rated capacity. This data is crucial for power systems in postal and telecommunications as well as for operational power battery packs.
