Move towards Azure

Previously the website was hosted on a private server using a home office network connection which is not reliable, redundant, properly managed etc. Now the entire site is migrated towards Azure whereas the security features within Azure required also an application update. TLS Version 1.2 and above shall be used to communicate with the new Azure hosted webservices, which means that the application also needed to be updated.

Version older then are deprecated

Version and below are no longer supported and shall no longer be able to receive licenses from the new platform. This means that all users have to update the application to continue using it. Most unfortunate this unforseen problem is in the middle of a new feature (cell slot combining) whereas we can't postpone the migration.

Cutover to Azure shall be completed at the end of July. In the comming days you will have to upgrade to version or above

The new way of charging starts here...

Check out the grid view in the app which provides a near realtime view on all your cell chargers. Select the voltage column of a cell to see its charge curve and compare this with the vendor specifications. Features like you have never encountered in any other product.

  • Single view

    Multiple cell chargers shall be listed in a single view with near realtime data updates. Grid cells flash for elements being updated and the actual status of the cells are shown in the various colums.

  • Database

    All data is stored in a database including but not limited to the settings, charger cycle details, cell serial numbers (generated using the workflow engine) and much more. Open database design allows you to connect to the database and read these values to be integrated with your own software or tools.

  • Repurpose batteries

    With all the features at your disposal you are now able to test your cells much faster, keep a detailed record of each cell and by salvaging each battery you save the planet one step at a time.

  • Visualization

    MegaCellMonitor is not only showing the capacity, cell resistance and temperature like other chargers do, it gives you full visibility of the charge process through a powerfull graphs and graphics.

  • Cell charge graphs

    Graphs are the most powerfull way to assess the batteries health. Vendor provided charge curves can be compared with the actual cell charge curve to asses the degradation of the cell. Abnormal curves also can indicate a potential failure of that cell.

  • Reliability

    Using the visual elements in the MegaCellMonitor allows to build reliable packs that last a long time with a lowered risk of early failures. No other charger and software has these features which are now at your finger tips.

  • Pack building

    After testing enough cells you can now easily select which cells are should be combined to create the most optimal pack.

  • Cell packer

    With the integrated cell packer you select how many cells you want in parallel and in series. The MegaCellMonitor will go through the database and select the most optimal combination per cell pack. All these values can then easily be exported to Excel or any other tool for further processing. When using existing tools, like repackr, then you can export the available cells and paste them straight into repackr.

  • High performance

    Building cell packs that are tuned ensure a consistent charge and discharge cycle of the cell pack. Equal capacity ensures that packs are more balanced and very little energy is wasted during balancing cycles. This saves energy which you can use for powering your equipment longer.
