How long will the 48V 200Ah LifePO4 Powerwall Battery for house last? This is what most users are thinking about. The 48V 200Ah LifePO4 Powerwall Battery for house is a lithium-ion battery using lithium iron phosphate as the positive electrode material. We know that the cycle life of lead-acid batteries is about 300 times, and the maximum is 500 times. The lithium iron phosphate power battery has a cycle life of more than 2,000 times, and can be used for 2,000 times with standard charging (5-hour rate).
The lead-acid battery of the same quality will take 1 to 1.5 years at most, while the lithium iron phosphate battery will have a theoretical life of 7 to 8 years when used under the same conditions. Comprehensive consideration, the performance-price ratio is theoretically more than 4 times that of lead-acid batteries.
Since the 48V 200Ah LifePO4 Powerwall Battery for house is more and more widely used in today's life, let's briefly introduce the service life of lithium iron phosphate battery.
1.48V 200Ah LifePO4 Powerwall Battery for house will have different discharge rates in different environments:
Lithium iron carbonate batteries will have different discharge rates in different environments, and the minimum discharge rate can reach 0.5c, and the maximum discharge rate can reach 10c, and no matter what kind of discharge rate this battery is, in The discharge process will be very flat. Generally speaking, the voltage is very stable and will almost remain unchanged. Only when the power generation of the lithium iron carbonate battery is about to end, will it be found that it will have a sharp decline, which can be It is very effective to show that the lithium iron carbonate battery has very good discharge characteristics, which means that its real life is very long.
2.48V 200Ah LifePO4 Powerwall Battery for house display under different temperature conditions:
The lithium iron carbonate battery will also have different discharge phenomena at different adjusted temperatures. We set the temperature to minus 20 degrees to more than 40 degrees. At this time, you will find that the lithium iron carbonate battery generates electricity at 23 degrees Celsius. The capacity of the battery can reach 100%, and the discharge amount at 0 ℃ will be more than 78%, which means that the discharge rate of the tri-iron lithium battery is different under different temperature conditions, so everyone needs to estimate the iron carbonate. When explaining the lithium battery, it must be kept in a specific temperature range, so the estimated result is better, but in terms of its performance under extreme temperature conditions, carbonic acid The real life of iron-lithium batteries is very long, which can reach more than 570 discharge cycles.
3. The experiment of placing the lithium iron carbonate battery at zero voltage:
Put the 48V 200Ah LifePO4 Powerwall Battery for house into the zero voltage experiment, everyone will find that after the battery is fully charged in 3 days, it will continue to discharge in such an environment, and it will be found that its capacity will change very little. , which shows that its capacity recovery is very good.
Finally, the production of lithium iron phosphate is subject to patent disputes abroad, which is one of the reasons why ternary cathode material lithium batteries are widely used in foreign electric vehicles.
The lifespan of 48V 200Ah LifePO4 Powerwall Battery for house may not be 4-5 times longer than that of lead-acid batteries. For lead-acid batteries with relatively high technical content, there is no problem with the lifespan of 5 years. However, due to the problem of structural collapse of the negative electrode material graphite, lithium batteries will be scrapped even if they are not used for five years.
