The difference between energy storage lithium battery and power lithium battery


1. Different battery capacity

The battery capacity is tested by the discharge instrument, and the capacity of the general power lithium battery is about 1000-1500mAh; the capacity of the energy storage lithium battery is above 2000mAh, and some can reach 3400mAh.


2. Different application industries

Power lithium batteries are used in batteries for electric vehicles, electric bicycles, electric motorcycles, golf carts, electric equipment and tool drive power. Energy storage lithium battery packs are mainly used in energy storage power stations such as water power, thermal power, wind power and solar power stations, communication base stations, photovoltaic charging stations, UPS power supplies, etc.


3. The location of the battery management system BMS is different

In the energy storage system, the energy storage lithium battery only interacts with the energy storage converter at high voltage, and the converter takes power from the AC grid to charge the battery pack; or the battery pack supplies power to the converter, and the electrical energy passes through the converter. The converter is converted into AC and sent to the AC grid. The BMS of an electric vehicle has an energy exchange relationship with the motor and the charger in terms of high voltage. In terms of communication, it has information exchange with the charger during the charging process. In the entire application process, it has detailed information with the vehicle controller. interact.


4. Different types of batteries are used

For the sake of safety and economy, lithium iron phosphate batteries are often used when choosing lithium batteries. At the same time, many energy storage power stations use lead-acid batteries. The current mainstream battery types of power lithium batteries are lithium iron phosphate batteries and ternary lithium batteries.

5. Different performance and design


Power lithium batteries focus more on charging and discharging power, requiring fast charging rate, high output power, and vibration resistance, especially emphasizing high safety and high energy density to achieve long-lasting battery life, as well as weight and volume requirements. Energy storage lithium battery emphasizes battery capacity, especially requires operation stability and service life, and mainly considers the consistency of battery modules. In terms of battery materials, attention should be paid to expansion rate, energy density, and uniformity of electrode material performance, in order to pursue the overall energy storage equipment. long life and low cost.


6. Different in nature


Power lithium battery refers to the battery that provides power for transportation. Lithium battery for energy storage is mainly used for emergency power supply, charging station, communication base station, etc.
