What is the voltage of the battery pack?

It depends on the type of battery it is:

1. The rated voltage of a ternary lithium battery is 3.7V, and the rated voltage of a ternary lithium battery is 3.7V. The charging voltage is 4.2V.

2. The rated voltage of a lithium iron phosphate battery cell is 3.2 V, and the charging voltage is 3.65 V.

3. The nominal voltage of a lead acid battery is 2 V and the charging voltage is 2.4 V.

Electric batteries are the energy sources that power the tools. They primarily refer to the batteries that power electric cars, electric trains, electric bicycles and golf carts.

It is mainly different from the starter battery used to start the car engine. Sealed valve lead acid batteries, open tubular lead acid batteries andlithium iron phosphate batteries are mainly used.

On July 31, 2018, the comprehensive management platform for national monitoring of new energy vehicles and traceability of electric battery recycling was launched in Beijing.

New energy vehicles:

New energy vehicles are promising due to their energy-saving and respect for the environment, but the biggest problem we face is their industrialization. Sales prices remain high. As for foreign hybrid vehicles, the price difference between the same type of hybrid and gasoline Toyota Camry reaches 80,000-100,000 yuan, while the price difference between the domestic BYD pure electric E6 model and the same type of gasoline vehicle is amounting to more than 200,000 yuan. Although the low operating and maintenance costs of vehiclesIf new energy vehicles in the later period can gradually make up the price difference of a single purchase, the high purchase price has undoubtedly become an important obstacle to the industrialization of new energy vehicles.

The upper limit of charging voltage of a single lithium iron phosphate battery on Pacific Automotive Network is 3.65V. Generally, the upper limit voltage of charging of lithium iron phosphate battery is 3.7-4V and the lower discharge limit voltage is 2-2.5V. The voltage of lithium battery is one of the important indicators to measure the performance of lithium battery discharge. Potential difference between the positive and negative electrodes of the lithium battery in a certain state.

Common 18650 battery with lithium iron phosphate battery voltage is divided into lithium ion battery and lithium iron phosphate battery. The rated voltage of lithium ion battery is 3.7V, the charging cutoff voltage is 4.2V, the rated voltage of lithium iron phosphate battery is 3.2V, the cutoff voltage charging is 3.6V, capacity is generally 1200mAh. 3000mAh, common capacity is 2200mAh-2600mAh.

Why is the lithium iron phosphate battery voltage 3.2V?

Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as the positive electrode material. The cathode materials of lithium ion batteries mainly include lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material currently used in most lithium-ion batteries.

The rated voltage of the lithium iron phosphate battery is 3.2Vand the charging ends at a high level.The electric voltage is 3.6V and the low discharge voltage is 2.0V. Due to the different quality and process of positive and negative electrode materials and Electrolytic materials used by different manufacturers, there will be some differences in their performance.

3.2V is a lithium iron phosphate battery, which can discharge to a large capacity. This type of battery is now used in electric vehicles. This type of battery has a long lifespan and is lightweight! 3.6V and 3.7V are the same as lithium polymer batteries. The upper limit of lithium polymer batteries is 4.2 and the lower limit is 2.6. The general standard is 3.7V.

The charging voltage of the lithium iron phosphate battery should be set to 3.65V, and the rated voltage is 3.2V. Generally, the maximum charging voltage can be 20% higher than the voltagenominal ion, but it is too high. Voltage can easily damage the battery. 3.6 V. If the voltage is below this indicator, it is not overloaded. If the battery is set to a minimum of 3.0 V, it should be charged. Then 3.4V is 0.4V higher than the lowest, and 3.6 is 0.6V higher than the lowest. The extra 0.2V can free up half the power. which means that each charge is twice as much as 3.4V. Usage time Since the battery is used a certain number of times, the lifespan is increased by half. Therefore, increasing the charging voltage without damaging the battery will increase its lifespan.

The discharge platform of lithium iron phosphate battery is: 3.2V. The discharge range value is: 2.5-3.65V. This maximum charging value can be changed according to customer needs (protection card parameters). this is the charging voltage maxial set to 3.85V and reaches 3.85V, the protection voltage is reached and the protection board will automatically cut off the charging circuit to protect the battery.

Lithium-ion battery voltage Lithium-ion battery discharge platform refers to the voltage change state of the battery when a fully charged lithium battery is discharged. When a battery is discharged at constant current, the battery voltage goes through three processes, namely falling, stabilizing and falling again. Among these three processes, the stable period is the longest. The longer the stabilization time, the higher the battery discharge platform. The level of the discharge platform is closely related to the battery manufacturing process.
