The Application of 12 volt 100 amp Hour Battery

Lithium-ion batteries are widely used. At present, electric vehicles, electric bicycles and electric tools at home and abroad all use lithium-ion batteries as energy storage power sources. Lithium-ion batteries have the advantages of small size, light weight, and high output power. Various mobile power sources have been widely used. In the future, with the development of new energy vehicles and people’s higher and higher requirements for environmental protection and energy, lithium-ion batteries will also be used more.

12 volt 100 amp Hour Battery

Lithium batteries are widely used all over the world. Lithium batteries have many advantages, but they also have many disadvantages, such as:

  • At present, domestic electric vehicles generally use 12V car batteries, which have a short service life. Generally, the batteries need to be replaced once every 3-4 years.
  • Long charging time: Generally, it takes 5-8 hours for the charger to fully charge the battery. If it needs to be used for a long time (such as: long-distance travel), this will greatly reduce the cruising range.
  • Now the mileage of the car is getting higher and higher. Due to the low charging efficiency of lithium batteries (generally only 70% of a single charge). So the charging time will be relatively longer.
  • Most of the currently used lithium batteries are lithium polymer batteries, which have the characteristics of small size and light weight, but they also have certain requirements for temperature. Lithium batteries are prone to combustion and explosion in an environment where the temperature is too high.
  • If you need to run around with the battery pack frequently (such as: long-distance travel), you need to carry multiple battery packs, and the time and cost will increase a lot.
  • The currently used car batteries are mainly lead-acid batteries, but due to their serious environmental pollution and high prices. Therefore, more and more lithium battery packs are used in electric vehicles, so what are its advantages?

1. Overview

The voltage of the lithium battery pack is 12V, the rated operating voltage is 100V, the operating temperature range is between -20°C and 60°C, and the working environment temperature range is between -40°C and 65°C.

The battery pack is powered by a 12V DC power supply, and is connected into a 12V DC battery pack through a series-parallel circuit. Various protective circuits used in electric vehicles are installed on the battery pack. Its specifications are as follows:

2. Market conditions

Judging from the current market situation, the market situation of 12V 100 Ah lithium battery pack is better than that of lead-acid battery, but the price is also more expensive than lead-acid battery. With the development of electric vehicles in recent years, the demand for lithium battery packs is increasing, and the price will also increase. Therefore, in the next few years, the 12V 100 Ah lithium battery pack will have a relatively large increase.

3. Main application scenarios

  • Electric vehicle motors are powered by lead-acid batteries, with a service life of about 3 years, while lithium batteries can be used for more than 10 years.
  • Electric bicycles: At present, the domestic electric bicycle market has great potential for development, and its demand for lithium batteries is also very large. With the improvement of living standards, people’s requirements for quality of life are also getting higher and higher. The advantages of lithium batteries, such as long cycle life and good safety performance, make them an ideal energy source for electric bicycles.
  • Energy storage system: Lithium battery energy storage system includes: energy storage power station (renewable energy power station), power grid, etc.

4. Precautions for use

  • Avoid putting the battery pack and flammable items in the same room to avoid fire.
  • When charging the battery, ensure that the power used is a 12V DC power supply. If you need to use other power supply, you need to ensure the stability and safety of the power supply.
  • For battery packs that are often used in harsh environments, it is recommended to perform a discharge test after each charge (discharge current is at least 2 times the rated current).
  • The greater the internal resistance of the battery, the smaller its capacity, and its actual capacity will be lower than about 80% of the rated capacity, so it is necessary to ensure that the battery has sufficient capacity.
  • The failed battery should be replaced in time to avoid personal safety accidents and environmental pollution.
  • If the battery explodes, the battery should be cooled immediately and disposed of in time.
