Problems solved by technology

[0011] According to conventional calculations, the battery has almost no power to discharge at this time, but the measured battery can still discharge 34% of the power
In this case, even if the current intelligent UPS estimation method is used, because the battery voltage jumps greatly at this time, it is difficult for the UPS battery backup time estimation system to effectively locate the current state of the battery in one step. There is often a big difference in time

Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the principles and applications of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] The relationship between battery discharge rate and capacity

[0045] The inventors found that the discharge time of the battery is related to the discharge current and the discharge cut-off voltage, and the dischargeable capacity of the battery is related to the discharge current. For example, for a BP7-12 type 12V7AH battery (commercially available from Meimei Battery Co., Ltd.), there are two sets of discharge data in Table 1 and Table 2.

[0046] Table 1: BP7-12 constant current discharge characteristic data: A (25°C, 77°F)

[0047]

[0048] Table 2: BP7-12 batter...

Abstract

The invention relates to an estimation method of battery electricity preparation time under the condition of varying loading, a corresponding estimation device, and a power system with the estimation device. The method takes influence of the varying loading into consideration, and estimation of the power preparation time is accurate. The supportive maximum discharging multiplying power and power can be computed before the varying loading, and therefore computer crash can be avoided. Due to the fact that the estimation method adopted for the discharging multiplying power is of certain generality, correct pre-estimation can be carried out while the specific specification of batteries usually does not need to be considered.

Description

technical field [0001] The invention relates to a method for estimating battery back-up time, in particular, to a method for estimating battery back-up time under variable load conditions and a corresponding system. Background technique [0002] Backup time refers to the continuous working time of the battery under a certain load. Backup time prediction is one of the core functions of battery management in the backup power system, which is directly related to the reliability and availability of the system. For more important power systems, the prediction of backup time is particularly important. The traditional backup time prediction method stores the discharge current and time relationship table or the power and time correspondence table in the system, and some advanced methods also add some capacity and time correction coefficients, which can basically predict accurately the condition that the load remains unchanged . However, in the actual application process, because s...
