Abstract

The invention discloses a lead-acid battery residual energy on-line measuring system which comprises a data acquisition module, a data processing module and a display module which are connected in sequence, wherein a current sensor is arranged in the data acquisition module, and is used for conducting real-time monitoring on charge-discharge current of a battery; the data processing module is used for conducting time integral of signals collected by the current sensor to acquire the real-time discharge quantity of the battery. The measuring system adopts the depth of charge (DOC) as the parameter for reflecting the charged state of the battery, and the parameter is calculated by adopting the actual capacity of the battery but not the non-nominal capacity, and can better reflect the actual condition of the battery; besides, the measuring system can periodically conduct deep discharge on the battery, the capacity can be restored, the Ct value can be rectified, and the accuracy of the measuring system can be improved.

Description

technical field [0001] The invention relates to an online measurement system for the remaining power of a lead-acid storage battery, belonging to the technical field of measurement. Background technique [0002] A battery, also known as a secondary battery, is a device that can convert the obtained electrical energy into chemical energy for storage and convert chemical energy into electrical energy for output. Lead-acid batteries are widely used in automobiles, ships, petrochemical and other industrial sites, and are one of the traditional and widely used batteries. [0003] At present, the SOC of the battery is usually used to represent the remaining power of the battery, and the traditional SOC measurement method uses the nominal capacity of the battery for calculation. However, with the influence of aging and other factors, the nominal capacity of the battery will change, thus these measurement methods cannot accurately reflect the actual situation of the battery in time...
