Abstract

The invention relates to a battery state monitoring system. A battery is connected with a power utilization device. The battery state monitoring system comprises a sampling resistor, a sampling circuit, an analysis unit and a transmission unit, wherein a first end of the sampling resistor is connected with an electrode of the battery, a second end of the sampling resistor is connected with a charge-discharge interface, the sampling circuit is used for sampling a current passing through the sampling resistor and processing the current to obtain sampling data, the analysis unit is used for comparing the current sampling data with historical sampling data and analyzing a load abruptly-changing state of the current power utilization device, and the transmission unit is used for receiving the current load abruptly-changing state and sending the current load abruptly-changing state to a user terminal through a network. In the battery state monitoring system, the sampling circuit is used for sampling a charge or discharge current of the battery electrode in real time and amplifying and processing the current to obtain the sampling data, the analysis unit is used for comparing the sampling data currently sampled with pre-stored sampling data and sending a comparison result to the user terminal so as to inform a user, the battery state monitoring system is short in sampling time and accurate in sampling result, real-time monitoring and notification can be achieved, and high efficiency is achieved.

Description

technical field [0001] The invention relates to battery monitoring technology, in particular to a battery state monitoring system. Background technique [0002] Conventional batteries or battery packs are widely used in electronic devices and provide power for electronic devices such as notebook computers, mobile phones, and various types of security alarms. At present, batteries are widely used in daily life and national production due to their environmental protection. However, in the application and production process (formation) of the battery, its voltage and current often need to be monitored to achieve the purposes of safe use, optimal control, and performance improvement. [0003] Many domestic institutions have begun to study new methods for automatic monitoring of batteries. In battery monitoring, it is mainly aimed at the detection of battery cell voltage, battery pack voltage, current and temperature. At present, people have done a lot of research on the probl...
