The complexity and difficulty of laboratory management are increasing day by day
With the increasing number of laboratory test instruments and test samples, superimposing the need for laboratory's own certification and accreditation, The traditional laboratory management model based on manual and paper or the lims system which can only meet the basic process is no longer suitable,Many problems have been exposed: Traditional lims can only meet the basic business process, but it has poor scalability and low performance efficiency. It is difficult to track the whole processing process of the sample, and it is difficult to trace the error when it is found, which wastes manpower and material resources and slows down the progress. Data is easy to lose, difficult to accumulate, difficult to reuse, and manual transmission can not guarantee the authenticity of data, timeliness; The experimental data are scattered in different systems/files, so it is difficult to make use of the data analysis value.

Data processing is time-consuming, laborious and error-prone
The data obtained from the test equipment need to go through manual calculation, display, comparison, screening, fitting and other operations to find the difference, analyze the results to determine whether the chart is meaningful, and distribute and report. Engineers process between 200 and 500GB of data per day from different sources and types,It is not only labor-intensive, the error rate is high, and the data is not deeply mined, and the utilization rate is low.

The format and form of the report are different, and the issuing efficiency is low
Battery testing needs to go through a large number of complex and repetitive verification work, during which the amount of data generated is far beyond our imagination, and engineers often need to collect and calculate a large amount of information and data through excel, and then use word to make various analysis reports, such as physical and chemical test reports, safety test reports, electrical performance test reports, etc. In the face of huge workload, problems such as software stutter, format distortion, data asynchronism, and manual operation are often a headache for engineers. If we continue to use the traditional reporting method, it will not only waste a lot of time and labor costs, but also the generated report data icon is not intuitive enough, and it is difficult to realize data sharing and management.
