Solar storage battery life expectancy？The cycle times of 48V lithium battery for energy storage are closely related to the service life of batteries. The battery capacity will be reduced a little after completing one cycle, and the service life of 48v lithium solar battery will also be reduced. How long is the cycle life of lithium battery? One of the reasons why lithium batteries replace lead-acid batteries is that the cycle life of lithium batteries is longer than that of lead-acid batteries, and they do not need maintenance.
Cycle life refers to how many times the battery can withstand charging and discharging before the battery capacity decreases to a specified value under a certain charging and discharging system. The cycle life of a lithium battery represents the number of times that the 48 volt 200ah lithium battery can be recharged and discharged before its capacity drops to a certain level. According to the data, lithium energy storage batteries generally achieve a cycle life of more than 5000 times.
Although the purchase price of lithium iron phosphate battery is two to three times that of lead-acid battery, the long-term economic benefit is still much higher. In other words, if the cycle life of lithium iron phosphate battery is long enough, even though the initial purchase price is a little higher, it is still cost-effective overall. In fact, the quality of the lithium energy storage battery mainly depends on its material. Generally speaking, a high-quality battery has a long life, which can effectively reduce the cost of repair and maintenance, as well as the overall investment in the system.
The national standard stipulates the cycle life test conditions and requirements for lithium ion batteries: charge for 150 minutes under the constant current and constant voltage 1C charging system at 25 ℃ room temperature, and discharge to 2.75V cut-off under the constant current 1C discharge system as a cycle. When one discharge time is less than 36 minutes, the test is completed, and the number of cycles must be greater than 300.
In fact, the number of cycles of lithium ion battery is related to the production technology level and material formula of the manufacturer of lithium ion battery, in addition to the different use modes of users. The service life of lithium battery is often affected with the increase of service time. The service life of lithium battery will be longer if the lifepo4 battery solar lithium is used properly
