What is the connection between inverter and lithium batteries?

UPS is an emergency power system. The cells in it can use lithium batteries, nickel-metal hydride batteries, storage batteries, etc. In the past, most inverters used fully sealed, maintenance-free lead-acid batteries as energy storage devices. However, in 2018, Huawei's independently developed lithium battery inverter was launched and received unanimous praise from users.

Three 12V 18650 batteries. Can they be used in powering a UPS? UPS. Lithium battery inverters and rack inverters are different types of UPS power supplies. The main difference between them is the battery technology used.

1. Lithium battery inverter uses lithium-ion batteries as power supply. This battery has the characteristics of high energy density, long life,e low self-discharge, etc., featuring high efficiency, high reliability and long service life. long-term operation for the UPS system.

2. The rack-mounted UPS uses lead-acid batteries as the power source. Lead-acid batteries are a mature technology, inexpensive but with a relatively short lifespan. In a UPS system, a rack UPS typically needs to replace the battery to ensure backup capacity. Therefore, lithium battery UPSs have higher reliability and lifespan, while rack-mounted UPSs are cheaper and easier to maintain.

What is the difference between UPS uninterruptible power supply and lithium battery power supply?

The voltage of three 18650 batteries in series is 11.1V. The UPS charger is usually 13.5 V. 13.5 V is different from 11.1 V. Probably too high. The discharge low voltage shutdown line is generally 10.5V. During discharge, 11.1 V can quickly drop to 10.5 V.

Thus, the charging and discharging parameters of the inverter itself do not change, but the type of battery is modified, which is very bad and does not increase the discharge time, but can pose a danger. (Lithium battery charging parameters are incorrect and easy to explode)

How to convert 3.7 volt DC power of lithium battery to 220 volt AC power

UPS uninterruptible power supply generally uses AC power. When the mains power is cut off, it can quickly switch to the battery power output inside the UPS, so it can continue to be used when the power is turned off and unconnected devices are also turned off.

Lithium battery power is the direct output power of the battery, which is equivalent toswitch to the output power from the battery inside the inverter after the inverter is turned off.

It takes a lot of effort to use cell phone batteries as 220V charging power.

1: For 3.7V batteries, you need about 80 batteries.

p>2: Your battery has a limited capacity, calculated based on a single battery capacity of 1000 mA, it can be discharged instantly based on a discharge rate of 1 Ah after inverting 80,000 mA to 220 V AC, which means it is basically useless
