1. How long does the outdoor power
supply last for several years?
Outdoor power supply is an outdoor multi-functional power supply with built-in lithium-ion battery and its own energy storage capacity, also known as For portable AC and DC power supply. The outdoor power supply is equivalent to a small portable charging station, which has the characteristics of light weight, high capacity, high power, long life and strong stability. So how long is the life of the outdoor power supply? How many years can it be used?
The number of cycles is a unit used to express the life of the outdoor power supply, and charging + discharging counts as one cycle. The current life of lithium batteries is that they can still be used after 1500-2000 cycles, and the capacity is still greater than 80 percent of the initial capacity. At the same time, with the continuous development and progress of lithium battery technology, the cycle life of lithium batteries will be longer.
For example, the life of an outdoor power supply is 1000 times, which means that when the power supply is charged from 0 percent to 100 percent, and then discharged to 0 percent, there are about 1000 such cycles. If the outdoor power supply is used once a week, the estimated lifespan is about 19 years. (1000 times ?? 48 times a year = about 20 years). If used according to the working day cycle, the estimated life is about 4 years. (1000 times a year ?? 240 times a year = about 4 years)
Second, how to prolong the life of outdoor power supply
1. Shallow charging and shallow discharging
Shallow charge and shallow discharge means that the charge is not fully charged and the discharge is not completed. It is often used as an outdoor power source for lithium batteries as the inner core of the battery. The purpose of shallow charging and shallow discharging is to make the battery be used in a normal environment as much as possible. To prevent the occurrence of overcharge and overdischarge resulting in some abnormal fluctuations in the single cell, which will cause the final battery pack to fail to work. Therefore, shallow charging and shallow discharging is a theoretically supported method of using lithium-ion batteries. Moreover, from the perspective of the characteristics of lithium batteries, shallow charging and shallow discharging are more in line with the normal use of lithium batteries.
2. Moderate charging and discharging during idle period
Normal energy storage equipment will consume a certain amount of micro-consumption even when it is not in use, so in order to To maintain the vitality of the battery, it is necessary to perform a moderate charge and discharge in about 3 months or 6 months of idle time to stimulate the battery to work normally. The opposite of moderate charge and discharge is overcharge and overdischarge. Overcharge and overdischarge will also lead to losses of the battery, and the working efficiency of the battery will also decrease accordingly.
3. Charging with original chargers
Charging with original chargers is a very important common sense issue. Matching chargers can make charging more efficient higher, and it will not affect the power load of the battery.
4. Do not use it at excessive temperature
The operating temperature of the battery is limited by the operating temperature under normal circumstances. cause the battery to stop working. Conversely, the larger the operating temperature range of the battery, the better the quality of the battery and the more prominent its technical capabilities.
5. Pay attention to waterproof and moisture-proof
Most of the outdoor power supply bodies have cooling vents, so they are not completely waterproof. If water or rain will enter the interior through the heat dissipation port, it will easily cause damage to the battery. Therefore, a good outdoor power supply will be equipped with a good quality waterproof and moisture-proof power supply package, which is convenient for storage and convenient to carry.
