BMS Planner for Battery Packs
Pack information
Enter information on your planned pack in order to calculate what specific kind of BMS (battery management system) you're going to need for your planned build.
If you are still in the planning stages, you can use our pack planner tool to plan out your next pack.
If you need some guidance on the battery building process, we wrote a guide on how to build a battery pack that you should read.
This BMS planner tools requires all fields to be filled out. Here is a break down of what the fields mean so you can be sure you are inputting the correct information.
Nominal, minimum and maximum voltage of the cells you are using can be found on their datasheet. This information will allow us to calculate the maximum amperage and min/max voltage that the BMS will need to handle.
Capacity and C-Rate can also be found on the cells datasheet. This information allows us to check that you will not be over taxing your cells.
Series and parallel configuration will be based upon the layout of the pack you come up with. It will allow the BMS planner tool to make sure the BMS its suggesting has the right voltage target. It uses the parallel count to make sure you can hit your amperage target.
Finally max wattage will make sure the BMS can handle the amperage that will be requested of it and also it double checks all of the inputs above to make sure your pack can handle the load. The wattage you input is divided by the minimum pack voltage to determine the absolute maximum amperage possible.
After all fields are filled out the planner will list out options of BMSs that will best fit your battery build. Starting on the left side will be the one with the lowest amperage rating that will exceed your max amperage requirement. Moving to the right the amperage rating of the BMS shown will become higher then what would be needed. If your pack can handle it its nice to get a higher rated one so you can pull more power down later in time.
We wrote an article on series, parallel and the differences between them. You can check out that article here .
After you purchase your BMS, check out this guide we wrote that will help you to hook up your BMS to your battery pack .
