Description

technical field [0001] The invention relates to a battery monitoring system, in particular to a battery remote online intelligent monitoring system. Background technique [0002] No matter in power supply systems such as substations, power plants, UPS power systems or communication stations, batteries are used as backup power sources. Normally, the battery pack is in the standby state of floating charging, but in the case of AC power failure or other accidents, the battery is the only energy supplier for the load. Once the battery has a problem, the power supply system will face paralysis, equipment outage and other major operating accidents, so Real-time monitoring of battery performance status is very important. [0003] With the progress of society and the continuous improvement of informatization and automation, people's dependence on the power industry has further deepened, and higher requirements have been put forward for the reliability of the power grid system. No ...

Problems solved by technology

[0005] The traditional test method and defect of the battery: the status of battery maintenance: at present, the battery maintenance is mainly to regularly detect the voltage of each battery and the terminal voltage of the battery pack

Defects in traditional battery inspection and maintenance methods: The three detection methods belong to the traditional battery inspection and maintenance methods, which have many defects, such as: poor manual measurement accuracy, susceptible to human factors, real-time (especially in the discharge process) and poor continuity

[0007] Research and data statistics show that: ① Most of the early damage of the battery is caused by overcharging, which can also be confirmed by understanding the principle of the battery and real-time monitoring records of the charging process, so float charging, supplementary charging and equalizing charging The data has a high reference value for judging the performance of the battery, which is difficult to achieve by relying on traditional inspection and maintenance methods alone; It is difficult to find these hidden dangers during floating charge operation or small current checking discharge test, but these hidden dangers can be found through the instantaneous high current discharge of the DC internal resistance test (similar to the closing process of the electromagnetic closing mechanism)
