How to estimate the remaining UPS battery capacity? For the UPS power supply, the UPS battery is also one of the important components, how to estimate the remaining battery capacity? Dynamic calculation of battery capacity, calculated by battery current to time points, reflects how much the battery is inheined or released, and sometimes it is approximately to the exception of the battery. Users can start capacity expect to predict capacity. The basic method of capacity estimation is to obtain a set of 0.

05C10A discharge voltage curve of a set of standard batteries, and discharge the battery at a current of 0.05 C10A, compare the discharge end voltage and the discharge capacity every time time. For example, a standard battery 0.

05c10a is discharged to 12.5V for 200 minutes, while the battery 0.05c10a is discharged to 12.

5V for only 150 minutes, and the static capacity of the battery is a rated capacity of 150/200 * 100 = 75. Many situations are not waiting for the UPS battery to support how long it can support after the power outage, because the battery capacity is not too late. So I hope to make an estimate of the capacity of the UPS battery.

UPS is turned on or the run time or can be tested on the battery on the line. This test, especially the line test with important load is a suggested battery that supports the risk only a short time, so that the energy loaded by the load is shared by the mains and battery, which prevents the UPS that causes the battery capacity. Output interrupt problem.

However, many UPS capacity estimates are percentage of direct estimation according to the voltage of the battery. Anyway, capacity estimates are only estimated, and 10 precision is quite good.
