Multiple Cell Monitors or "multi string" configuration: adding batteries in parallel to the same WatchMon supervisor

The Batrium system is very flexible, the cell monitors network is opto-isolated, that means you can technically start the daisy chain network wherever you would like, there is no correct/wrong order where you should start wiring the pack. The first cell on the daisy chain will be the first blue bar or cell #1 on the screen, the last cell on the network chain will be showing as the last blue bar on the screen. 
​ 
Batteries are normally wired starting from the cell #1 being the most negative cell on the pack and work all the way up to the most positive cell. 

​If you are constantly adding more cell monitors and batteries to an existing system, you don't necessarily have to re-configure the whole battery pack, it is easier to just keep on linking the new cell monitors from the last cell monitor on the daisy chain network. 

ToolKit software configuration

Example: you have 14 packs with one LongMon each and you decide to expand adding more packs in parallel. You will keep the 14s nominal but now you need to tell the system that you have 56 devices (LongMons) on the daisy chain network.


There are two easy step-by-step procedures:

  1. Setting up a new multi cell monitor system
  2. Adding more cell monitors to an existing configured system

Configuration procedure for new systems:

Step 1 - Click on "Menu" then "Tools" 

Step 2 - Click on "Wizard Setup"

Step 3 - add the total of devices (LongMons) you are using, in this example 56.

Step 4 - select "Different" ON, this enables you select the number of "Nominal series" in this example 14. 

Step 5 - The "Nominal Total Capacity" should be updated as you add more cells to your pack. If you have 100Ah cells and you have 4 in parallel, you should write 400Ah. 

Step 6 - Click "Save" 

Step 7 - Go back to the main monitoring screen "Chart", you will see 56 blue bars in this example. 

Adding more Cell Monitors to an existing configured system:

Step 1 - Click on "Menu" then click on "Hardware"

Step 2 - Click on "CellMon" tab and click on "Edit"

 

Step 3 -  add the total of devices (LongMons) you are using, in this example 56. Select "Different" ON, this enables you select the number of "Nominal series" in this example 14. 

Step 4 - Click on the "Shunt" tab and click on "Edit"

Step 5 - The "Nominal Total Capacity" should be updated as you add more cells to your pack. If you have 100Ah cells and you have 4 in parallel, you should write 400Ah. 

Identifying Cell Monitors: regardless of the order you wire the cells monitors on the chain, you can easily identify each CellMon, cell or pack using this procedure How to identify a specific cellmon using the led. Despite being easy to identify the cell monitors using the LEDs, labeling the packs also helps identification.
