Problems solved by technology
However, the stability of electronic devices may change after a period of operation, and it is prone to failure states, and the failure of electronic devices directly determines the safety of power battery operation
At present, the electric vehicle battery pack system in actual operation has many failures such as the decrease of the detection accuracy of the battery management system, the failure of the protection function, and the malfunction or non-operation of the high-voltage devices in the pack, resulting in the operation of the power battery pack under faulty or non-monitoring conditions. , there is a serious security risk
[0005] Since the output characteristics of the power battery pack are related to the single cells that make up the battery pack, and the characteristics of the single cells are related to the aging state of the battery, the output characteristics of the power battery pack gradually deteriorate as the operating time increases

The invention discloses a feed network type heavy-power battery testing device which comprises a monitoring server, a protocol gateway, a charge and discharge motor, a battery data acquisition module, a battery management system acquisition module and a power battery pack. According to the invention, accurate and reliable basis data can be rapidly and accurately provided for a power battery in the application to an electric vehicle. A background software system with a user programming capacity and a battery evaluating capacity carried in the feed network type heavy-power battery testing device ensures that a user can complete the detection of the function of a power battery pack and the testing of the output performance of the power battery pack according to a set control process, thus the feed network type heavy-power battery testing device has stronger practical value.
Description
technical field [0001] The invention relates to a grid-feeding high-power battery testing device, which belongs to the technical field of batteries. Background technique [0002] At present, with the development of battery technology, power batteries have greatly improved in terms of energy density, power density and cycle life. However, in the course of practice, it is found that after the power batteries are connected in series and parallel, the single cells are inconsistent, which makes the service life and dynamic characteristics of the whole group of batteries far inferior to the single cells, and cannot meet the requirements of applications such as electric vehicles and energy storage systems. . Therefore, with the large-scale development of electric vehicles, how to sort and test power batteries into groups, and comprehensively evaluate the electrical performance of groups of batteries has become a key issue that needs to be solved urgently. The power battery test d...
