IMPORTANT: Inverter/charger voltage calibration


Some inverters/chargers have been known to return inaccurate results when measuring voltage.

In such cases, the inverter/charger should be calibrated as follows:


Compare the voltage values displayed by the inverter/charger with that of a calibrated voltmeter.

If the actual voltage differs by more than 100mV from that measured by the inverter/charger, apply this difference to the highlighted values above (i.e. if actual voltage = 56V while inverter voltage = 56.5V,

the voltage difference = 0.5V should be subtracted from each of the set values above).


Note: Some inverters/chargers have pre-programmed lead-acid related algorithms & functionalities such as auto-desulfation and equalisation. These functionalities should be disabled, where possible.


  1. Serial Communication


BlueNova® 52V NG batteries include serial communication functionality via CAN protocol. Serial-connecting a 52V NG battery to a compatible inverter, charger or other third-party hardware device normally negates the necessity of manual voltage-based installation procedures, as described in the section above. 


The installation procedure for serial integration varies and is determined by the serial-compatible peripheral hardware that is being integrated with.

 

  1. Parallel Connection


BlueNova batteries with 123Smart firmware version 5.4 & higher as well as BMMC firmware version 2.5 & higher include MultiCap™ technology. Batteries with MultiCap™ can be connected in parallel to each other to increase overall capacity, regardless of the age difference and/or rated capacity difference between any two of the batteries in the parallel configuration ONLY IF ALL of the requirements below are met:


  1. The nominal voltage of all parallel-connected batteries is the same (i.e. 52V), and
  2. The installed capacity @C10 of the largest battery in the parallel configuration is no larger than 4 x the installed capacity @C10 of the smallest battery in the same configuration, and
  3. The correct firmware versions are installed on all batteries in the configuration & updated accordingly, and
  4. Each battery is operating within its warranty period.


Check the currently configured parallel settings of any 52V NG battery by scrolling with CTRL button to page 6:


Parallel Status

FW:BMMC 2.4

G#:8eb7c95e

PO:N=1 I=1

The 3rd line of the display in this example should be read as follows:

Parallel Operation: Number of batteries = 1. This individual battery communicates 1st on the CAN bus.


The procedure below describes how to correctly configure BlueNova batteries for parallel operation:


  1. Switch off all batteries.


  1. Interconnect (daisy-chain) all batteries with standard RJ45 network cables from any one of the two available RJ45 ports on each battery.


  1. For each battery, keep the CTRL button depressed while switching the battery on at the power button. This will initialise parallel configuration.


  1. Press the CTRL button to set the total number of batteries in the parallel configuration on each battery. Note: The displayed value will increment with each press of the CTRL button up to a maximum value of 10, and then return to 1.


  1. Press & hold the CTRL button for about 3 seconds to save this number on each battery.
  1. Once the last battery has been programmed as described above, the contactor for each battery should close after about 30 seconds or less.


  1. MONITORING



  1. MAINTENANCE


  1. General Guidelines


  1. Do not short circuit the battery terminals.
  2. Do not use the battery without a BlueNova® approved integrated BMS solution.
  3. Do not disassemble, pierce, cut or in any way physically alter any part of the battery.
  4. Do not burn, incinerate or otherwise subject the battery to extreme heat.





  1. Storage Instructions


  1. Ensure that the battery is switched off when stored.
  2. Disconnect the communication cable.
  3. Always store batteries in a cool and well-ventilated area – ideally 25°C ± 3°C.
  4. Store away from moisture and heat.
  5. Do not store batteries upside down for overly long periods.
  6. Check the open circuit voltage of stored batteries at least once per month. Recharge batteries sufficiently and frequently enough to prevent the open circuit voltage falling below 40V.
  7. Ensure that the stored battery’s state of charge is always above 50%. 100% SOC is optimal.


  1. TROUBLESHOOTING


All BlueNova® products contain integrated circuitry as a safety measure against possible damage from electrical malfunction. Under such conditions, one of the following errors will be displayed on the integrated OLED display. Please follow the procedure described in each case:

Fuse Error

  1. Check fuse(s) & terminal connections.
  2. Power cycle the battery (switch off, then on again).


  1. Recovery from over-discharge


BlueNova® batteries will automatically disconnect from the inverter/charger if the battery is over-discharged to the point that the cell voltage over any single cell reaches 2.85V. For BlueNova’s 52V NG range, the integrated electronics that drive the OLED display will remain operational while the total battery voltage remains above 40V (2.5V x 16 cells).


If an over-discharged battery’s total voltage falls below 40V, the battery will automatically enter DDL (Deep Discharge Lockout) mode. Recovery from DDL mode might still be possible, depending on how long the battery has remained in this state. Please contact BlueNova Technical Support in such cases.


If an over-discharged battery’s display is still operational, the battery can be recovered from this state by following the procedure below:


Page 7:

OVERRIDE?


PRESS+HOLD

Navigate to the page on the left by pressing the CTRL button.

Ensure that the battery will be charged upon reconnecting.


Override

Confirmation

Page:

OVERRIDE

*   IS   *

 ACTIVE

Press & hold the CTRL button to initiate the override procedure. The display will jump between the one illustrated on left and the main page (page 1) below.


Page 1:

Vbat:41.14V
Ibat:0.000A
SOC :0.00%

Verify that the battery is being charged by checking that the value for Ibat on the display is positive. Once the battery’s contactor can be heard closing, the CTRL button can be let go.




  1. EMERGENCY & FIRST AID


  1. In case of fire


  1. Evacuate danger zone. Open ventilation in the room if possible.
  2. Extinguish fire with a CO2 fire extinguisher.
  3. After the fire has been extinguished, immerse any remaining smoking cells completely in water.

Wear protective gear during this procedure.


  1. Skin contact


  1. Wash the affected area immediately with soap and water.
  2. If irritation persists, seek medical attention.


  1. Eye contact


  1. Rinse eyes immediately with clean water continuously for at least 15 minutes.
  2. Seek medical attention immediately afterwards.


  1. Ingestion
