What are the standard sizes and models of lithium batteries for electric vehicles?

Differentelectric vehicle batterieshave different sizes and designs. The voltage of each unit of a lead-acid battery is 2 V. Each battery is composed of 6 units and the voltage is 12 V. The most commonly used lithium battery combination for electric bicycles is composed of three or four batteries connected in series. Three batteries connected in series are 36 V and four batteries connected in series are 48 V. Nowadays, there are also single 16 V batteries consisting of 8 battery cells.

The capacity of lead acid batteries is specified by the voltage. Taking a 12V lead-acid battery as an example, its minimum operating voltage is 10.5V, its maximum operating voltage is 13.5V, and it is discharged. from the highest operating voltage to the lowest operating voltage. Indicates 100% discharge.At this time, the battery stops working. The power released during this process corresponds to the capacity of the battery.

Common capacities of 36V are: 10Ah, 12Ah; others include 14Ah, 17Ah and 20Ah.

Common capacities of 48V are: 10Ah, 12Ah, 14Ah, 17Ah, 120Ah; others include 15Ah, 16Ah, 18Ah, 22Ah and 24Ah.

Advanced lithium-ion battery technology ion Safety and application in emerging key markets (electric vehicles) have stimulated a global boom in research and development, so lithium-ion batteries are destined to occupy an important place in the fields of electric vehicles and new energies. Currently, the most widely used lithium-ion battery in electric vehicles is lithium iron phosphate battery, which has good thermal stability and safety.ty and is relatively inexpensive.

These factors make lithium iron phosphate batteries the first choice for small electric vehicles and PHEV batteries. However, among lithium ion batteries, lithium phosphate batteries have relatively low specific energy, specific power and operating voltage. Lithium cobalt oxide and lithium manganate batteries have more advantages in the application of large pure electric vehicles.

However, the widespread application of lithium battery electric vehicles also has certain problems, mainly due to the performance limitations of lithium batteries, including safety, service life, cost , operating temperature and lithium material supply. -ion ​​batteries.
