18650 lithium ion battery 3.7v

release time:2024-03-28 Hits: Popular:AG11 battery

　　What are the technical parameters of 18650 lithium ion battery 3.7v?

　　UPS lead-acid battery technical parameters

　　UPS lead-acid battery is one of the most important equipment in an energy storage power station. The cost accounts for about 80% of the system. The technical parameters of the battery are very important to the system design. The following uses lead-carbon lead-acid battery as an example to explain the key parameters of the battery such as capacity. , discharge depth, number of cycles, etc. When selecting and designing batteries and inverters, pay attention to the maximum charge and discharge current of the battery.

　　1. Battery capacity

　　The capacity of a UPS battery is determined by the amount of active material in the battery, which is usually expressed in Ah or mAh. For example, the nominal capacity of 250Ah (10hr, 1.80V/cell, 25℃) refers to the capacity released by discharging at a current of 25A for 10 hours at 25℃ to reduce the voltage of a single battery to 1.80V.

　　2. Rated voltage

　　The potential difference between the positive and negative terminals of a UPS battery is called the rated voltage of the battery. Common lead-acid batteries have three rated voltages: 2V, 6V, and 12V. A single lead-acid battery is 2V, and a 12V battery is made up of six single batteries connected in series.

　　3. Maximum charge and discharge current

　　18650 lithium ion battery 3.7v are bidirectional and have two states, charging and discharging. This current is limited. Different batteries have different maximum charging and discharging currents. The battery charging current is generally expressed as a multiple of the battery capacity C. For example, if the battery capacity C=100Ah and the charging current is 0.15C, it is 0.15100=15A.
