Introduction：
Energy storage lithium batteries mainly refer to lithium battery packs used in energy storage power supplies, solar power generation equipment, wind power generation equipment, and renewable energy energy storage.
A power battery refers to a battery with a large electrical capacity and output power. A power battery is a power source for tools. It mostly refers to lithium batteries that provide power for electric vehicles, electric trains, electric bicycles, electric forklift and golf carts. The power source of new energy vehicles is generally mainly power batteries.
The difference between the tow lithium batteries?
1. Different battery capacities
When all lithium batteries are new, use a discharge meter to test the battery capacity. Generally, the capacity of power lithium batteries is lower, while the capacity of energy storage lithium battery packs is higher. That's because energy storage lithium batteries are usually designed with large capacity, suitable for long-term energy storage and release,
and optimized energy efficiency. Power lithium batteries are designed to provide high power output, can withstand frequent charge and discharge cycles, and focus on response speed and acceleration performance.
2. Different application industries
Power lithium batteries are used as batteries for driving power supplies for electric equipment and tools such as electric vehicles, electric motorcycles, electric forklifts and electric golf carts; used in transmission and substations to provide closing current for power units;
Energy storage lithium battery packs are mainly used in energy storage power stations such as hydropower, thermal power, wind power and solar power stations, peak-shaving and frequency-regulating power auxiliary services, digital products, power products, medical and security, and UPS power supplies.
3. Different types of battery cells used
For safety and economic considerations, energy storage power stations often use lithium iron phosphate batteries and semi-solid batteries when selecting lithium battery packs. Some larger energy storage power stations also use lead-acid batteries and lead-carbon batteries. The current mainstream battery types for power lithium battery electric vehicles are lithium iron phosphate batteries and ternary lithium batteries.
4. The battery management system (BMS) has different locations
In the energy storage system, the energy storage lithium battery only interacts with the energy storage inverter at high voltage. The inverter draws power from the AC power grid to charge the battery pack; or the battery pack supplies power to the inverter, and the electric energy is converted into AC by the inverter and sent to the AC power grid. The BMS of electric vehicles has energy exchange relationships with both the motor and the charger at high voltage; in terms of communication, it has information exchange with the charger during the charging process, and has the most detailed information exchange with the vehicle controller during the entire application process.
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. They especially emphasize high safety and high energy density to achieve long-term endurance, as well as lightweight requirements in terms of weight and volume; The preparation of energy storage lithium batteries emphasizes battery capacity, especially operational stability and service life, and considers battery module consistency. In terms of battery materials, attention should be paid to expansion rate and energy density, and uniformity of electrode material performance, in order to pursue long life and low cost of overall energy storage equipment.
