WatchMon4: battery supervisor

Regular price $0.00 AUD

NOT SOLD SEPARATELY

 

BMS central processor that watches the individual CMU cell monitoring units and provides supervision functions.  The supervisor is able to notify a remote system(s) of the battery state and when required trigger evasive action to prevent damage to battery pack.

How to install the WatchMon Toolkit software

Why do I need a starter kit not just the CellMons or WatchMon

The supervisor is not available individually by default except for those that have have experience in ordering our products. Starter kits ensure that you obtain all the necessary components to suit your application. If you have questions and looking for the appropriate starter kit please contact us, we can then assist you make the right selection.

Refer to the FAQ on how to define your bms requirements.

Processor

  • Data logging of key metrics for 10 years
  • Clock with backup battery
  • optional over the air (OTA) upgrades to firmware
  • upgrades firmware via USB
  • secure web encryption to allow SSL link when connecting to optional cloud portal via MQTT.
  • prevent all outputs from resetting when the processor firmware is updating (no transient on/off/on)
