Set-up
Setting up a Lithiumate™ BMS
- Connect a terminal to the serial port on the BMS controller
- Power-up the BMS
- At power-up, the terminal shows the Main Menu
- Navigate the menu tree by pressing the digit corresponding to the menu item
- Return to the previous menu by pressing the ESC key. Pressing the ESC key repeatedly will get you back to the Main menu.
- You can jump back to the Home menu from any screen by pressing the 'H' key (rev 0.97 and above)
- If the CAN bus is used:
- If contactors are controlled by the BMS through the CAN bus, specify the format of the message that does so
- If other devices on the CAN bus measure the battery current and report the value, specify the format of those messages
- If the standard set of messages that the BMS controler places on the CAN bus interfere with some other device's messages, change their starting ID
- If a custom messages is required from the BMS controler, define its format and data
- Program the functions of input and output lines:
- If a normally closed interlock is used, switch the polarity from the default to normally closed
- Specify which inputs are used to measure battery current
- If any output (LLIM, HLIM, FLT) should be normally shorted to ground, switch its polarity from the default to normally closed
- If contactors are controlled by the BMS, select which tests are performed when turning on
- Program the battery pack arrangement:
- The 1st time it is powered-up, the BMS learns automatically how many cells are in the battery pack. To relearn, clear the number of cells in the 0th bank, and cycle the power; you may also enter the number of cells in each bank manually
- If using a number of batteries in parallel (each battery has its set of cell boards), specify that number
- Program the operating parameters:
- If the cells are other than LiFePO4, program the cell voltages
- Program the max charge and discharge currents during normal operation
- If the BMS measures the battery current with current sensors, specify their gain and offset
- Specify the nominal capacity of the battery pack
- Many other parameters may be customized, but usually they are left to their default
- Confirm that the BMS has found all the banks and all the cells
- Confirm that the BMS can control the Source (charge) and the Load (such as a motor controller) to limit the battery current
- Confirm that the BMS is able to read the battery current
