Problems solved by technology

On the one hand, the investment cost is high; on the other hand, the online discharge load fixed in the DC system of the substation is only used once a year in the checking discharge work, not only the utilization rate is low, but also as the substation becomes unattended, Whether the online discharge load can work normally cannot be verified in time
In addition, the existing battery comprehensive monitoring system only relies on voltage test and internal resistance test, and the test parameters are relatively simple, which cannot accurately evaluate the health status of the battery

Abstract

The invention discloses an intelligent storage battery operation and maintenance device based on a plug-and-play type discharge load. The device comprises an internal resistance testing unit, a voltage collecting unit, the plug-and-play type discharge load and a station-end control unit, wherein the internal resistance testing unit, the voltage collecting unit and the plug-and-play type discharge load can be electrically connected with a storage battery, are provided with serial port communication modules and are in communication connection with the station end control unit through the serial port communication modules. The intelligent storage battery operation and maintenance device based on the plug-and-play type discharge load has the advantages as follows: repeated recycling of one discharge load in a plurality of storage battery station operation and maintenance systems is achieved, so that cost and resources are saved; and meanwhile, the device performs instation communication by adopting a safe and stable serial port communication technology and does not require remote communication, thereby solving the problem of channel safety of remote communication.

Description

technical field [0001] The invention relates to an intelligent operation and maintenance device for a battery pack based on a plug-and-play discharge load. Background technique [0002] The existing battery integrated monitoring system can realize the remote discharge of battery packs, but due to the requirements of the power system for the remote control safety level, the requirements for the communication channel are very high. At present, the communication channel problem has become the core problem restricting the implementation of this scheme; and In the existing DC integrated monitoring system, each substation must add a set of online discharge loads while adding the system to each substation. On the one hand, the investment cost is high; on the other hand, the online discharge load fixed in the DC system of the substation is only used once a year in the checking discharge work, not only the utilization rate is low, but also as the substation becomes unattended, Wheth...
