TPM - Tesla Pack Monitor

Tesla Pack Monitor in Action

Check Tesla battery packs outside of the car - and in

Tesla Pack Monitor connects to a sealed or unsealed classic S/X or modern 3/Y/S/X battery pack and gives you a quick report of battery condition.  If you are fixing a battery pack or at a salvage yard testing a bunch of battery packs or refurbishing a pack at your shop you will want the Tesla Pack Monitor!  


All of the relevant internal data of the pack is available on the display inside the rugged carrying case which also holds all cables and a battery pack.  A detailed report is automatically generated for each pack scanned.  Reports can be viewed and retrieved from the unit with a web browser.


Information in the reports and on screen includes:

  • Serial number, part number (handy for mystery packs with missing labels)
  • Miles on the pack (Classic S/X. Estimated from total discharge for 3/Y/S/X)
  • State of health: reduction in capacity since new
  • DC fast charge (supercharge) vs AC charge data
  • Voltages for all Cells (and modules for Classic S/X) & imbalances - easy to spot bad cells (and modules) and where to repair
  • Scan My Tesla (SMT) and similar apps can be connected to the TPM via WiFi
  • This product under active development and supports updates over WiFi
  • And more..


The unit is currently $500 and includes the cable for Classic S/X.  The cable for 3/Y is an additional $50.  Same for 2021+ S/X.


TPM can also report in-vehicle.  Requires our OBD-2 male cable ($25) and model specific Tesla diagnostic port to OBD-2 female connector (widely available at Amazon etc)


Shipping is an additional $20 in the USA, $30 to Canada and $45 to Europe.
