Energy storage lithium batteries mainly refer to lithium battery packs used in solar power generation equipment, wind power generation equipment, and renewable energy storage energy. Power battery refers to a power source with a large electric energy capacity and output power. The power battery is the power source that provides the power source for the tool. The power source of the new energy vehicle is generally mainly the power battery. The following is the difference between energy storage lithium battery and power lithium battery.
Different battery capacity
In the case of new batteries, use a discharge meter to test the battery capacity. Generally, the capacity of power lithium batteries is about 1000-1500mAh. The capacity of the energy storage lithium battery pack is above 2000mAh, and some can reach 3400mAh.
Different application industries
Power lithium batteries are used as batteries for driving power supplies of electric vehicles, electric bicycles, electric motorcycles, electric equipment, and tools; used in power transmission and substations, and to provide closing current for power units.
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, peak and frequency modulation power auxiliary services, digital products, power products, medical and security, and UPS power supplies.
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. The converter takes electricity from the AC grid to charge the battery pack, or the battery pack supplies power to the converter, and the electric energy is converted through the converter. The converter is converted into AC and sent to the AC grid.
The BMS of the power lithium battery of an electric vehicle has an energy exchange relationship with the electric motor and the charger at high voltage; in terms of communication, there is information interaction with the charger during the charging process, and in the entire application process, it interacts with the vehicle controller There is the most detailed information exchange.
Different types of batteries used
Energy storage lithium battery energy storage power station due to safety and economic considerations, when choosing lithium battery packs, lithium iron phosphate batteries are often used, and more energy storage power stations use lead-acid batteries and lead-carbon batteries. Power lithium batteries The current mainstream battery types for electric vehicles are lithium iron phosphate batteries and ternary lithium batteries.
Performance and design are not the same
Power lithium batteries focus more on charging and discharging power and other aspects, requiring fast charging rate, high output power, and vibration resistance, especially emphasizing higher safety and high energy density to achieve long-lasting battery life and lightweight requirements in terms of weight and volume.
The preparation of energy storage lithium batteries emphasizes battery capacity and especially requires operational stability and service life. Consider the consistency of battery modules. In terms of battery materials, attention should be paid to the expansion rate and energy density, and the uniformity of electrode material performance in order to pursue overall storage. The long life and low cost of energy equipment.
