Problems solved by technology

[0004] At the same time, most of the battery management systems on the market do not have a corresponding human-computer interaction interface. In the testing process of secondary batteries such as sodium-sulfur batteries and even the subsequent operation process, the human-computer interaction function is very important for artificially handling some faults and temporarily imposing certain items. Tasks such as instructions are of great importance

Embodiment

[0039] For the convenience of description, the relevant technical terms appearing in the specific implementation are explained first:

[0040] QT is a cross-platform C++ GUI application development framework developed by Qt Company in 1991;

[0041] CAN is the abbreviation of Controller Area Network (CAN). It was developed by German BOSCH company, which is famous for R&D and production of automotive electronic products, and finally became an international standard (ISO11898). It is the most widely used field in the world. one of the buses.

[0042] 485 bus: adopts half-duplex working mode and supports multi-point data communication.

[0043] figure 1 It is a schematic diagram of the QT-based sodium-sulfur battery management system of the present invention.

[0044] In this example, if figure 1 As shown, a QT-based sodium-sulfur battery management system of the present invention includes: a PCB acquisition board module, a PCB main board, a relay protection device, a furnace...

Abstract

The invention discloses a QT-based sodium-sulfur battery management system, which monitors the operating state of the sodium-sulfur battery on the interface of a host computer by collecting information such as the voltage and temperature of a sodium-sulfur battery in real time; specifically, according to the sodium-sulfur battery According to the operation state of the sulfur battery, different operation strategies are implemented. When the battery operation state is abnormal, the relay protection device is activated to protect the operation safety of the system; when the battery operation state is normal, the battery is charged according to the pre-established operation strategy. Discharge and battery temperature rise and fall control, and finally through the real-time monitoring of the working status of the sodium-sulfur battery pack by the host computer, the management and protection of the sodium-sulfur battery operation are realized.

Description

technical field [0001] The invention belongs to the technical field of battery testing and operation monitoring, and more specifically relates to a QT-based sodium-sulfur battery management system. Background technique [0002] The battery management system (Battery Management System, referred to as BMS) is the bridge between the battery and the user. Whether it is in the battery test or operation process, the battery management system plays an irreplaceable and important role. The main target of the battery management system is the secondary battery. The purpose is to improve the utilization rate of the battery and prevent the battery from abnormal charging and discharging during testing and operation. The battery management system has a wide range of applications, mainly in the testing and operation of new batteries, electric vehicles, robots and drones. [0003] Although the current battery management system can meet the needs of some battery operations, the functions ar...
