Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] see figure 1 , is a schematic diagram of a device for quickly testing and evaluating the status of a storage battery according to a preferred embodiment of the present invention. Such as figure 1 As shown, the battery detected by the device for quick test and evaluation of battery quality provided by this embodiment is a 48V battery pack composed of 24 single batteries with a voltage of 2V connected in series.

[0033] The unique feature of the present invention is that the battery pack is further divided into a plurality of battery groups, and each battery group is tested separately to obtain the measured values ​​of the performance parameters of each battery group, and then the measured values ​​of these performance parameters are compare...

Abstract

The invention relates to a device and method for quickly testing and evaluating the quality of a storage battery. The storage battery is a battery pack composed of multiple single cells connected in series. The battery pack is further divided into a plurality of adjacent single cells. A battery group formed in series; the device includes a main control module and a plurality of battery detection modules communicating with it; each battery detection module is connected to a battery group in the battery group to obtain the measured value of the performance parameter of each battery group; The main control module is used to compare the measured value of the performance parameter of each battery group with the normal value of the performance parameter corresponding to the number of single batteries of the battery group, and when the measured value of the ohmic resistance is greater than the normal value, and the When the measured value of the capacitance is less than its normal value, it is determined that there is an abnormal battery in the battery group. The invention has the characteristics of fast detection speed and low cost, and can be applied to battery monitoring in power substations, communication base stations, UPS in machine rooms and the like.

Description

technical field [0001] The invention relates to the field of battery detection, more specifically, to a device and method for quickly testing and evaluating the quality of a storage battery. Background technique [0002] At present, the power system substation operating power supply, communication base station power supply, computer room UPS (uninterruptible power supply), as well as energy storage power stations, photovoltaic power stations, communication base stations, electric vehicles, etc., all use a large number of battery packs composed of dozens of single-cell batteries connected in series. power or backup power. Since battery management personnel generally manage dozens, hundreds or even thousands of batteries at the same time, and the locations are relatively scattered, there is an urgent need for a quick and efficient way to know whether the battery pack is normal and to roughly locate the problem battery. When the battery pack is found to be abnormal, go to the ...
