The first step in battery monitoring is to gather data from the different meters. This is generally done electronically. Optionally, some of the meters can also be recorded manually. Some measurement data can be read directly from the meter and entered, others must first be calculated. The collected measurement data is plotted in a graph to define a standard trend for energy use. The next step is to monitor the difference between expected and actual energy usage. Once a standard usage pattern has been identified and the causes for energy use variations have been identified, it is time to determine goals (targets or targets) for the future.
Monitoring of results
With this, we complete the cycle and come back to measuring energy consumption. A typical feature of energy monitoring is that it is a continuous process in a feedback loop to achieve continuous improvement in energy performance. After setting targets and implementing the necessary measures, the continuous cycle ensures that managers are aware of the extent to which the measures are successful. Based on this, immediate follow-up actions can be planned and targets further tightened.
Determining target values
This sets the levels of energy consumption desired by the management. These ‘targets’ or targets are based on the data obtained from the data collection on past performance, and thorough knowledge of the business or production process. Objectives are set for work: ambitious but achievable.
In order to achieve continuous control of energy use, achievement of targets and monitoring of effects of savings measures, reporting to the right managers is required. This report enables the managers to make decisions and take action to achieve the intended goals. It is also possible to determine whether goals have been achieved or not.
Implementation of energy monitoring requires some preparation. First of all, the main energy users must be identified. In general, the largest consumption items are distributed over a small number of processes, such as central heating or certain machines. An energy scan of the company (building and (process) equipment), vehicle or ship is necessary to identify energy consumption points and to determine their consumption level.
Furthermore, it is necessary to determine what other measurements will be needed to make a good explanatory analysis of energy use. This data will later be deployed against energy use. These are variables or factors that directly or indirectly affect energy usage, such as production quantities, temperatures, grade days, building occupancy, etc.
Thanks to the information obtained, it is possible to set more realistic goals than before. The goals are now based on the actual energy or battery use of the building, vehicles, ships, the process or the organization.
A good initial goal is the regression line. This line shows what has been the average use in the past. The use of energy in the future at or below this level is, therefore, an achievable goal. The challenge lies in eliminating high peaks in use.
As an ambitious goal, the lowest value of the past can be set aside. The challenge is to take the best performance from the past as the norm.
Do you know that the resolution for standard laser printers can be 600 dots per inch (dpi). Read more about laser printers.
Knowing which cartridges work in your printer is incredibly important. By ordering the wrong product you could end up spending much more than you think or at least having to organize an inconvenient return shipment if the error is caught on time, so before ruining the entire printer!
