Example Embodiment
[0026] The preferred specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments. Considering that general communication base stations use lead-acid batteries as backup power sources, in this embodiment, the “batteries” mentioned all refer to lead-acid batteries. However, it should be understood that the technical solutions disclosed in this embodiment are not only Limited to this, it can also be applied to other batteries with similar electrochemical characteristics.
[0027] A method of online estimation of battery capacity, such as figure 1 As shown, it includes the following steps:
[0028] 1) Use the DC loading method to detect the current in the battery twice, and calculate the internal resistance of the battery;
[0029] 2) Use online measurement method to detect battery electromotive force...
