Summary of Contents for Faktor BMS123 Smart

  • Page 1 User Manual BMS123 Smart...
  • Page 2 Introduction After the introduction of affordable LiFePO4 batteries, off-grid solutions became available for wide public. It is vital that such batteries are charged very carefully. In other words, they can easily be over- charged, or over-discharged. Cell-temperature and current are also very important, in order to guarantee a long life.
  • Page 3 Conclusion : the upper limit is safe-guarded by entering V-max / V-bypass, and the lower limit by V-min. Package contains (12 Volt, 4 cells) IN Cell Board OUT Cell Board 2 Cell Boards 2 Current sensors Piece of 0,75 mm² wire for the interconnections Connector unlock tool...

  • Page 4: Specification

    Specification Item Specifications Idle Current of the BMS-IN / OUT Modules < 2 mA inclusive current sensors and standby Bluetooth OUT Module current when Bluetooth <25mA connection is active Idle Current BMS-modules < 100 uA Balancing Current 1 Amp. Number of Cells 2 - 255 Current-sensors 100 Amp.
  • Page 5 Mounting the IN Module Start to mount the IN-Board on the first cell. It is important this is the cell on the minus (-) side of the battery pack. Solder a wire on the solder pad of the IN-Board. (Photo 2) Connect this wire to the minus (-) side of the cell. After the IN-Board is connected the LED will start blinking every second, this shows the IN-Board is trying to send out data messages to the following cell board.
  • Page 6 Mounting the „Between“ cell Modules After the IN-Board was installed, please proceed by the cell boards. Now, prepare the BMS-boards as shown on photo number two. Use thick solid-copper wire for this, for optimum accuracy. (the bypass-current has to flow through these wires) Take your time: the result has to look good! The BMS module always has to be mounted on the 'plus' pole of the cell.
  • Page 7 The picture below shows a basic setup of a 12 Volt battery pack...
  • Page 8 The picture below shows a setup with separated battery banks. When the battery pack has separated battery banks the interconnection has to be changed to prevent interference from other components in the system. The data connection has to be galvanic isolated. This can be done by the following procedure:...
  • Page 9 1- Cut of the PCB track between the two gold dots. ( red circled in the picture above ) Use a twisted pair cable and use both terminals. IN-Board 'option switch' functions Settings The option switches can be changed when the system is active. The table below shows you the functions of the option switches.
  • Page 10 module you will find the option switches. Set option switch number 4 to the ON position. Now the “Auto zero” procedure will be active. The currents on the App screen will show 0 Amps in a couple of seconds. Set the option switch number 4 back to the OFF position again.
  • Page 11 The App First connection Go to the App store for Apple devices and search for “BMS123 Smart”. Install the BMS123 Smart App on your Apple device. For Android devices go to the Play store and search for “BMS123 Smart”. Install the App on your Android device.
  • Page 12 Bluetooth section of the OUT-Board. Now your BMS will be discovered, Tab on the discovered BMS123 Smart device to make a connection. The App will ask for a password, this password is stored in the BMS to prevent everybody with a Bluetooth device can control your BMS. The standard password is “1234”.
  • Page 13 “Discharge restart”. Prevent auto-lock: Enabling this function prevent the device goes into sleep mode. Show simulator: If you don’t have an BMS123 Smart but you like to discover the App, you can run a simulator.
  • Page 14 After the settings has been done, Tap the “< BMS123 Smart” button to show up the overview Dashboard The overview dashboard shows you all information you like to know. The Solar panel shows the status of the incoming energy, next to this graphic presentation you will find details like: Incoming charge current, Incoming power, harvest energy today, total of harvest energy.
  • Page 15 The light bulb shows the status of the outgoing energy, next to this graphic presentation you will find details like: consumed current, consumed power, consumed energy today, total of consumed energy. When you Tap the “ i ” sign off the battery you will enter the battery details section.
  • Page 16 Battery details The battery details shows you detailed info of the battery pack. Voltage and temperature of each cell is displayed. Please be aware the temperature during bypass mode is much higher than the really cell temperature. Green values are in the safe range, yellow values shows balancing cells and red values are out of the safe range cells (above V max or below V min for example) On top of the screen five warning lights will show critical errors.

  • Page 17: Controlling External Components

    Controlling external components On the OUT Module you will find two bi stable signal relays to control external components of your off- grid system. This can be “solar chargers”, “Maximum power point trackers”, “inverters”, etc. An example is the “enable” pin on many Victron inverters. The maximum current through these relays may be 1 ampere.

  • Page 18: Module Details

    Discharging and charging will be stopped when there is a communication error. For example when there is a loose contact in the string of cells. In this case the OUT module has no information of the cells before, and will stop charging and discharging for safety reasons. Discharging and charging will be both stopped when the temperature limits will be exceeded.
