Problems solved by technology

[0004] However, as the power battery pack becomes longer in use or the internal single battery fails, the input and output current values ​​​​of the power battery pack will not match the corresponding generator and motor speeds. It is easy to overheat the power battery pack and cause a fire or the mine car cannot be used normally due to insufficient power.

Abstract

The present application relates to the field of battery technology, and in particular, to a power battery charge and discharge management method, device, electronic device and medium. The method includes: acquiring abnormal current information, the abnormal current information representing current information of a power battery pack exceeding a preset current range; determining a torque command according to the abnormal current information and feeding it back to a generator or a motor, adjusting the speed of the generator or motor, and the torque command It is a control command to adjust the torque of the motor or engine; obtain the voltage information of each single battery according to the abnormal current information; judge whether the voltage information of each single battery exceeds the preset voltage range, if the voltage information of any single battery exceeds the If the voltage range is preset, the fault information is generated and fed back to the display device. The present application has the effect of improving the stability of the gasoline-electric hybrid unmanned mining vehicle.

Description

technical field [0001] The present application relates to the field of battery technology, and in particular, to a power battery charge and discharge management method, device, electronic device and medium. Background technique [0002] Under the background of today's environmental pollution and energy shortage, my country will develop new energy vehicles as one of the measures to solve environmental pollution and alleviate energy shortage; Electric vehicles, pure electric vehicles, solar vehicles, etc. came into being; among them, gasoline-electric hybrid vehicles, as a kind of new energy vehicles, are recognized by people for their advantages of low exhaust emission, low fuel consumption and strong endurance. At the same time, with the continuous development of technology, driverless technology has become more mature; after the combination of new energy vehicles and driverless technology, it has been more favored by people. For example, gasoline-electric hybrid unmanned min...
