Using a Elektro Automatik charger with an Lithiumate BMS.
Note: Elektro Automatik no longer manufactures these chargers, and the latest version of the Elithion software no longer supports them.
The Lithiumate BMS (rev 1.33 to 2.35) interfaces with a single Elektro Automatik PS 8000 DT/2U/3U power supply series through the CAN bus.
- Check of there is a CAN interface card type IF-C1 inside the charger
- Connect the CANH and CANL lines of the BMS to the CANH and CANL lines of the charger.
- The CAN bus needs two terminations, one at each end of the bus.
- The BMS has an internal termination, which can be removed
- The charger's internal termination may be configured on or off through the set-up menu
Configure the charger to operate with the BMS.
- Turn the Power Switch ON
- Verify that the output is switched off, and also the remote LED must be off.
- Verify that either the BMS is off, or it is not yet programmed to talk to this charger
- Push the current rotary knob and voltage rotary knob at the same time for 5 seconds to open the settings menu.
- Select "Baud" with the voltage rotary knob
- Set with the current rotary knob the baud rate to 500 kBd
- Select "Base ID" with the voltage rotary knob
- Set with the current rotary knob the base ID to 0x614 (when the value is decimal push the current rotary knob)
- Select "Broad ID" with the voltage rotary knob
- Set with the current rotary knob the Broad ID to 0x620 (when the value is decimal push the current rotary knob)
- If the charger should have a CAN termination, set "Bus Term" to "Yes"
- Push the current and voltage rotary knob at the same time for 5 seconds to save the settings
Configure the BMS to operate with the charger.
- Select messages to this charger: Home / Set-up / More / CAN bus / Communication with other devices / Chargers / Elektro Automatik
- Set up receiving the charger current from this charger:
- Specify the nominal current setting of the charger: Home / Set-up / Current sense / Source current / Current sensor / Gain
- Enter the nominal current in [A]; For example, for 70 A, enter 70
- Set up RX messages: Home / Set-up / Current sense / Source current / CAN message / ...
- ... ID: set to 616h
- ... 1st data byte: set to 3
- ... Length: set to 1: 1 byte
- ... Offset: set to 0
- ... Units: set to 1/100th of the nominal current setting of the charger
- The 1/100th is because the charger uses % as units
- For example, for 70 A, enter 700 [mA/count]
- ... Direction: set to Yes: + = into battery
- Reset the BMS controller for changes to the CAN message ID to take effect (Cycle power off and on, or press H / 6/ 7)
- If required, change the CAN speed to match the CAN speed of the charger:
- Home / Set-up / Set-up / More / CAN bus / Can Bus rate
