Introduction to household lithium battery energy storage systems

The life of a home energy storage lithium battery system depends on several factors, including the following: Cycle life: Cycle life refers to the number of times a battery completes charge and discharge cycles. The cycle life of lithium batteries typically ranges from a few thousand to tens of thousands of cycles, depending on factors such as the battery's chemistry, design, and manufacturing quality. Decay rate: Decay rate refers to the rate at which battery capacity gradually decreases as the number of cycles increases. The decay rate of lithium batteries is usually slow, but as the number of cycles increases, the capacity decay will gradually accelerate. Charge and discharge depth: Charge and discharge depth refers to the proportion of battery capacity used in each charge and discharge. Normally, a shallower charge and discharge depth can extend the life of lithium batteries. Deep discharge will increase the stress and loss of the battery, so it is recommended to avoid completely draining the battery. Environmental factors: Temperature is an important factor affecting the life of lithium batteries. High temperatures will accelerate the rate of battery degradation, so exposure to high temperatures should be avoided as much as possible. In addition, overcharging and over-discharging can also reduce the life of lithium batteries. Generally speaking, under normal circumstances, the life of a household energy storage lithium battery system can reach several thousand charge and discharge cycles, and it is expected to be used for more than 10 years. However, it should be noted that the actual life span will be affected by specific usage conditions and charging and discharging strategies, so proper use and management of the battery system is crucial to extending its life.
