12V Solar Storage Lithium Battery and Eco-friendly Energy Solution for Solar Power Systems

The 12V solar storage lithium battery, a crucial part of solar power systems, serves as an eco - friendly energy solution, efficiently storing solar energy and providing stable power for various applications, thus promoting sustainable energy utilization.

Performance Characteristics

Long Life: The cycle life of lithium batteries is usually much longer than that of lead-acid batteries. Under normal working conditions, the charge/discharge cycle times are far more than 500 times, and the service life can reach about 5 years or even longer, reducing the frequency and cost of battery replacement.

Low Self-Discharge Rate: Generally, it can be less than 1% per month, less than 1/20 of that of nickel-metal hydride batteries. This enables the battery to maintain a high power reserve even when not in use for a long time, reducing the trouble of frequent charging. The self-discharge rate comparison of common 12V batteries

Structure and Principle

Usually, it is composed of 3 or 4 lithium batteries with a voltage of 3.7V connected in series to reach the rated voltage of 12V. In addition, it also includes components such as a protection board and a sheet metal casing. The protection board can automatically cut off the power supply when the battery encounters situations such as overload, overcurrent, overcharging, and overheating, playing a role in protecting the battery. The sheet metal casing provides mechanical protection for the battery, preventing the internal battery cells from being damaged by collisions, extrusions, etc. The specific parameters of a 12V 200Ah lithium iron phosphate energy storage power battery are as follows in the table:

Application Scenarios

• Automotive Field: It can be used as the auxiliary power supply for hybrid and pure electric vehicles, powering the vehicle's electronic devices such as the audio system and in - vehicle computer. It can also be used as a starting battery. Compared with traditional lead - acid starting batteries, it has the advantages of light weight and long life.
• Emergency Backup Power Supply: In homes, offices, or commercial places, etc., it can be used as the backup battery of a UPS (Uninterruptible Power Supply). When the mains power is interrupted, it provides emergency power support for key devices such as computers, routers, and monitoring equipment, ensuring the normal operation of the devices and avoiding data loss or business interruption.
• Outdoor Camping: It can provide stable power for lighting equipment such as camping lights and flashlights, and also supply power for small electrical appliances such as portable fans, car refrigerators, and outdoor speakers. It can also charge electronic devices such as mobile phones, tablets, and cameras through an inverter, meeting outdoor entertainment and living needs.

Precautions

• Charging: Choose a suitable charger and avoid using an incompatible charger to prevent overcharging or damage to the battery. When charging, place the battery in a well - ventilated and temperature - appropriate environment, and avoid charging in high - temperature, humid, or flammable environments. For example, a certain 12V lithium battery is recommended to use a charger with a charging voltage of 14.6V and a charging current not exceeding 100A.

• Storage Method: When not in use for a long time, keep the battery power at about 50% and store it in a dry and cool place. Charge and discharge the battery once every once in a while to maintain the battery's activity.

• Operating Environment: Avoid using the battery for a long time in an environment with too high or too low temperature. High temperature will accelerate the aging of the battery, reduce the battery life, and may also cause safety problems such as battery swelling. Low temperature will reduce the battery capacity and discharge efficiency. Generally, the suitable operating temperature of 12V sheet metal cased lithium batteries is between - 20℃ and 60℃.

12V sheet metal cased lithium batteries,with their excellent performance and wide applicability,exhibit unique advantages in numerous fields.However,during use,it is essential to follow the correct methods to ensure their performance and safety.
