Supervisor with on board cell monitoring. Typically used with OEM batteries such as those from Tesla, Chevy Volt etc.
The WatchMonPlus (WM5 & WM7) are phased-out Batrium battery supervisors. The newest supervisor is called the WatchMonCORE.
WatchMonPlus combines the supervisor and cell management into one compact single device. The WM5 and WM7 are generally the same with the core difference being:
We always start by setting up the software and communicating with the device. This occurs with just the WatchMon connected via the provided USB cable.
Multi-string is still possible but we are limited by the number of cell monitors in the onboard system. We do have the ability to run multiple WatchMonPlus in master/slave mode (Multi-Mon).
The next step is to wire up the batteries to our system.
Before wiring up please refer to Design Considerations WatchMonPlus.
Please note that the WatchMonPlus was designed for shared balancing cables such as those you would find in 18650 PCB cell holders and repurposed cells (salvaged EV)
WARNING: Always disconnect the batteries from the WatchMon when re-configuring or working on the batteries and ensure that it is wired up correctly. Test the wiring by using the TestMon before plugging into the WatchMon. Failure to follow this Warning may cause damage to the WatchMon and/or batteries.
Depending on your configuration, add jumpers to the wiring pins as required.
An example of wiring up to 18650 PCB Cell holders is in this video. Many of the steps are similar to repurposed cells (salvaged EV) with the balancing wires hooked up to pluggable connectors according to how many you are using in series.
Now that your batteries are connected to the WatchMonPlus we follow the same steps as we did with WatchMon4 to check for a circuit and ensure setup, created using the wizard, matches what you have wired up.
At this point, or later if you prefer, you can set up WiFi. Just remember that WiFi is 'read only' at present, so you cannot change the configuration if connected this way.
