Description
Photovoltaic energy storage lithium batteries are used as energy sources to obtain currents with stable voltage, stable current, stable power supply, little external influence, simple structure, easy portability, and convenient charging. Do not
Affected by external climate and temperature. Its performance is stable and reliable, and it plays an important role in all aspects of modern social life, and occupies a large proportion in the use of electric energy.
Now more and more lithium batteries are chosen as the power source of photovoltaic energy storage lithium batteries. Its advantages are,
- High-voltage photovoltaic energy storage lithium battery platform: the average voltage of a single battery is 3.7V or 3.2V, which is approximately equal to the series voltage of three nickel-cadmium batteries or nickel-hydrogen batteries, which is conducive to the formation of a battery-powered unit
Yuan.
- Compared with batteries, photovoltaic energy storage lithium batteries have higher energy density. High energy storage density, reaching 460-600Wh/kg, about 6-7 times that of lead-acid batteries; compared with lead-acid batteries,
Lithium batteries are lighter in weight, about 1/5 of the same volume of lead-acid products.
- Photovoltaic energy storage lithium batteries have a relatively long service life. The battery with lithium iron phosphate as the positive electrode can be charged and discharged 1 CDOD, and can be used for 1000 times. The lithium battery has strong adaptability to high and low temperature, and can be
It can be used in the environment of -20C–60C, and can be used in the environment of -45C after processing.
When choosing a photovoltaic energy storage lithium battery, we can determine the battery specification and model based on comprehensive considerations such as the battery’s communication protocol, voltage, weight, operating environment temperature, safety, and cycle life.
- Communication protocolAt present, the main communication protocols of photovoltaic energy storage lithium batteries are: RS485, RS232, CAN. Select the BIMS module of the battery according to the communication protocol.
- VoltageHere, the rated voltage and withstand voltage of the output terminal should be considered to determine the voltage and material of the photovoltaic energy storage lithium battery. The rated voltage of the battery should not be lower than the rated voltage of the motor. However, the battery The full voltage should not be higher than the voltage of the device. Therefore, it is sometimes seen that the voltage of the photovoltaic energy storage lithium battery is 12 strings of ternary lithium batteries, and the full voltage is 50.4V, instead of the commonly used 24V or 48V.
