What is the reason for the UPS reserve power supply without lithium ion batteries?

UPS reserve power supply No source design of lithium-ion batteries High General manufacturer is difficult to change lithium electricity due to lithium ion battery and lead-acid battery characteristics, charging curves and circuits, the charging equipment has different specifications of different label UPS batteries, so When the old UPS uses the client, the lead-acid battery pen is replaced into lithium electricity during each year, almost impossible tasks. The difficulty is, the specifications of the lead-acid battery, the capacitance is from 7ah to 70ah, and the electricity demand from 100ah to 500ah or higher demand. The lead-acid battery is stacked in parallel according to the demand string.

However, the lithium ion battery pack has a protected plate BMS that controls the filled. Therefore, if the lithium ion battery is placed in a lead-acid battery, a unit is saved in a voltage and capacitance (assuming is 48V, 30AH) and then the power demand in each computer room will be stacked in parallel, each battery pack BMS occurs. Because each battery pack has different voltage and power, the protection status occurs when charging or discharging, cannot be used.

If you make a single UPS battery pack according to the actual needs of customers, it will usually have hundreds of AH, and a battery pack will also have more than 100kg, especially related to the mobile phone communication machine room that scattered around the whole station, which is very inconvenient installation. More serious is that each customer needs difference, if it is not standardized by UPS power battery packages, each battery must be customized, relatively cost and price will be high, and it is. This is the top priority of the major brands at home and abroad, without any lithium-ion battery products on the UPS battery.
