Introducing the next generation of WatchMon supervisors. This revamps takes the lessons we have learnt from WM4 and builds on this proven platform with a few new features.

WatchMonCORE will be the core building block and additional components will link to this supervisor in the future.

Overview

BMS to suit LiFePO4, Lithium-Ion or custom chemistry
User configurable parameters and control logic
Configurable 30vdc 5A relay (i.e. remote circuit breaker trip, contactor or fan)
Additional inputs/outputs via Expansion Board purchased separately
Compatible with all Expansion Board (series 1, 2, or 3)
Clock with a backup battery
Data logging of key metrics for 10 years
firmware upgrades via USB
4-stage display of State of Charge (SoC%)
External ambient temperature sensor
Easy-to-use pluggable screw-terminal connectors
With distributed cell monitors capable of 28 Ah/day balancing adjustment for each cell
Link to Shuntmon with 500A or 1000A power rating
Compatible with MultiMon MM8

Remote Communication

WiFi connectivity (normal, disabled, or read-only)
CAN bus Opto-Insulated to remote charger/inverter equipment
future feature to connect to the cloud portal via MQTT (secure link).

Power Input

Built-in 8v to 30v DC-DC supply
With WiFi enabled consumes ~1.7W (Typical 48v battery budget 1Ah/day)

When powering the WatchMonCORE (version 4.5) with a supply above 30Vdc (i.e. 48V battery pack voltage), always connect to an isolated DC-DC (ideally 24Vdc) to ensure a robust, long-term, and reliable product.
