Problems solved by technology
Due to the multi-channel test, a large amount of test data will be generated every second. A large amount of test data will cause the CPU, network IO, and hard disk IO occupancy to remain high, causing the upper computer to be stuck; if the test data is transmitted regularly, the CPU, network The occupancy rate of IO and hard disk IO will show peaks and valleys, which will easily lead to abnormalities in the host computer, and even trigger a chain reaction that will lead to the collapse of the entire lithium battery test system, resulting in loss of test data

The invention provides a lithium battery test channel current limiting method and system in the technical field of lithium battery test. The method comprises the following steps: step S10, creating a token generation rate, a thread concurrency number, a token generation rule and a token bucket on an upper computer; step S20, the upper computer periodically generates request tokens based on the token generation rate and the thread concurrent number, and puts all the request tokens into a token bucket; step S30, the upper computer monitors the occupancy rate of the CPU and the memory in real time, and then dynamically adjusts the token generation rate and the thread concurrency number by using the token generation rule; and S40, the upper computer interacts with the middle computer based on the request token in the token bucket. The lithium battery test system has the advantage that the operation stability of the lithium battery test system is greatly improved.
Description
technical field [0001] The invention relates to the technical field of lithium battery testing, in particular to a current limiting method and system for a lithium battery testing channel. Background technique [0002] With the rise and development of new energy sources, lithium batteries, as green and high-energy chemical power sources, have the advantages of high energy, high power, and low cost, and are widely used in the new energy industry. In order to ensure the safety of lithium batteries, a series of tests are required for lithium batteries before leaving the factory. [0003] The lithium battery test system adopts a three-layer structure of the upper computer, the middle computer and the lower computer. In order to improve the efficiency of lithium battery testing, multi-channel testing is used at the same time, that is, one upper computer is connected to several middle computers, and each middle computer is connected. Lithium batteries are tested by a lower comput...
