What are the differences between energy storage lithium batteries and power lithium batteries.household energy storage lithium battery Manufacturing

1. Different battery capacity

The general power lithium battery capacity is between the range of 1000-1500mAh and the energy storage lithium battery is above 20000mAh.

2. Different application industry

Energy storage lithium batteries are relatively large, such as hydropower, firepower, wind power, solar power stations, these energy storage power stations, and digital products, power products, medical care, security UPS power supply, etc. Most of the power lithium batteries are used in electric equipment such as electric vehicles, electric tools, electric forks, and karts.

3. Battery management system BMS positions are different

In the energy storage system, the energy storage lithium battery only interacts with the energy storage transformer on the high voltage, and the variables pick up the power grid from the AC power grid to charge the battery pack; The transaction flow of the device is sent to the AC grid; the BMS of the electric vehicle has an energy exchange relationship with the electric motor and the charger in terms of high -voltage; in terms of communication, there is information interaction with the charging machine during the charging process. During all application processes , I have the most detailed information interaction with the vehicle controller.

4. Different types of battery cells adopted

For security and economical considerations, energy storage lithium batteries often use lithium iron phosphate batteries, lead -acid batteries, lead -carbon batteries; while power lithium batteries are mainly lithium iron phosphate batteries and ternary lithium batteries.

5. Different performance and design

The power lithium battery focuses on the power charging power and other aspects. It requires fast charging rate, high output power, and vibration resistance. Especially emphasizes higher safety and high energy density to achieve lasting battery life, as well as lightweight requirements for weight volume ; Energy storage lithium battery emphasizes battery capacity, especially requires stability and service life. Considering the consistency of battery module, battery materials should pay attention to the expansion rate and energy density, and the uniformity of electrode material performance to pursue the overall energy storage storage storage The length and low cost of the equipment.
