Table 11. Optional components that can be used in combination with the Li-ion battery

Installation

General information

Warning! Never install or use a damaged Li-ion battery.
Warning! Always use a proper fuse which fits the system needs.
Warning! Do not reverse-connect the Li-ion battery (polarity).

When connecting several batteries in series or parallel, always use batteries of the same brand, type, age, capacity and state of charge.

Unpacking

Check the Li-ion battery for damage after unpacking. If the Li-ion battery is damaged, contact your reseller or Super B. Do not install or use the Li-ion battery if it is damaged!

Preparing the battery for use

Caution! Do not operate the Li-ion battery beyond published maximum specifications.
Caution! Charging at deep discharge conditions can lead to venting, excessive heat, or thermal runaway of the cells.
Caution! This Li-ion battery stores fault conditions internally, like excessive charge current or deep discharge situations. Super B uses this information in the warranty process.

Warning! Do not overcharge the Li-ion battery.

Placement of the battery

Before it is used, the Li-ion battery must be positioned in such a way that it will not move around in its compartment during use. The Li-on battery may be placed on its long side, but not upside down or on its short side. If necessary, the Li-ion battery may be fixed in place by means of Super B mounting brackets. The brackets can be screwed in place by means of bolts or screws.

Figure 4. Placement of the battery

Connection wires

Use appropriate wire for the connection wires to prevent overheating and unnecessary losses. Use appropriate fuses matching the wires and load. Super B suggests to use 95mm2 connection wires. Connection wires with smaller diameters can cause overheating or unnecessary losses.

Using the BIB (Battery Interface Box)

Warning! Do not connect a load or charger directly on the Li-ion battery, always connect these devices at the load side of the BIB.

Consult with Super B for the BIB installation instructions.

Disconnecting the Li-ion battery

1. Turn off any device or charger the Li-ion battery is connected to.
2. Disconnect the negative wire from the – terminal of the Li-ion battery.
3. Disconnect the positive wire from the + terminal of the Li-ion battery.

Connecting Li-ion batteries in series and parallel

Connecting Li-ion batteries in series.

Caution! When connecting multiple batteries in series or parallel make sure that the SoC of all batteries is 100% to avoid unbalance in the battery bank.
Caution! Before connecting 4 or more batteries in series, always consult Super B
Caution! Depending on the installation a precharge circuit might be needed. For further information consult Super B or your dealer.

Figure 7. Batteries connected in series with external disconnect device and BCI.

Connecting Li-ion batteries in parallel

Caution! Before connecting 2 or more Li-ion batteries in parallel, the Li- ion batteries must be charged to 100% SoC.
Caution! For more than 4 Li-ion batteries in parallel connection consult Super B or your dealer.
Caution! Depending on the installation a precharge circuit might be needed. For further information consult Super B or your dealer.
Caution! Make sure that the disconnect device (relay) used, is suitable for the maximum continous (dis)charge current of the system.
OK: Equally divided battery current. All batteries contribute equally to the current into the load.
NOT OK: Current not equally divided. Batteries closest to load will have the highest contribution to the current into the load, whereas batteries further away from load will have lesser current contribution. Wear and tear will be higher on the Li-ion battery close to the load.

Connecting Li-ion batteries in series and parallel

Caution! Before connecting 4 or more Li-ion batteries in series and parallel, the Li-ion batteries must be charged to 100% SoC. ! Caution! For more than 4 Li-ion batteries in series and parallel connection consult Super B or your dealer.
  Caution! Depending on the installation a precharge circuit might be needed. For further information consult Super B or your dealer.

CANopen interface

The CANopen interface of the Li-ion battery must be used for communication with the BCI/ BIB and can be used for monitoring purposes. The Li-ion battery can be monitored using the Battery Monitor software and the touch screen display. To use the Battery Monitoring Software, the CAN bus of the Li-ion battery needs to be connected by means of CAN-to-USB interface to the computer on which the monitoring software and the USB drivers are installed. More information about the CANopen bus can be found at the CiA website: www.can- cia.org.

CAN Bus network topology

The CAN Bus must be used in a bus network topology. Do not use a ring- or a star topology. The maximum CAN bus length is limited. The Li-ion battery has a fixed bitrate of 250kbps.

In table 11 is an overview of these restrictions.

Bit rate| Bus length (L)| Max. stub length (S)| Accumulated stub length
---|---|---|---
250 kbps| 250 m| 11 m| 55 m

Termination Resistors

The CAN bus requires termination at the two ends of the bus. The USB-to-CAN interface may be connected anywhere to the CAN bus.
Use these resistors at the end nodes to prevent reflections on the line. The value of this resistor should be ±120 ohms.
Please note that the terminator can be connected directly to the second connector on the Li-ion battery by using the available Super B terminators.

CAN bus power

Due to the galvanic isolation between the BMS and the Li-ion battery’s CAN interface an external power supply is needed on the CAN bus.
The CAN bus can be powered through the CAN power cable (see figure 9). This situation may occur when a USB-to CAN interface is directly connected to the Li-ion battery. When using the SB BCI with one Li-ion battery, the CAN power cable is required.
When using the SB BCI with 2 to 16 Li-ion batteries, the CAN power cable isn’t required. The power is provided by the BCI.

Independent temperature sensor (optional)

For certain applications or systems which require our DNV Type Approved model, a 3rd connector is designed, to allow connection to an independent temperature sensor. The connector is only available on the Nomada Li-ion battery with DNV Type Approval, and a standard Li-ion battery does is not equipped with this 3rd connector. This sensor works independently from the BMS and is not electrically connected to the BMS, it is used as a redundant temperature guard.
It measures the battery temperature and switches at a fixed level, to send out a signal informing the user (or Energy Management System), that the battery has reached a temperature level that is too high.
The internal circuit can be powered from the CAN bus power, or by using the input connections within the Con 3 connector. The temperature sensor output is a fused open-drain output, pulling the signal line low when the temperature sensor has been activated. The sensor trip level is ~75°C.

In large installations where more than one independent battery sensor needs to be observed, the signal from all the Li-ion batteries can be connected in parallel, using a special y-split cable (see paragraph 3.6.2). Please contact Super B for more information about this connection, DNV application information, and supplied accessories.

Battery use

General information

Warning! It is required to use a Super B Battery Communication Interface (BCI) in combination with an external disconnect device or a Super B Battery Interface Box (BIB), for safe operation of the Li-ion battery.
Warning! In case of an undervoltage shutdown the charging current must be very low until a safe voltage is achieved.
Warning! Follow the safety guidelines and measures of chapter 1.

Caution! Charge the Li-ion battery before use.
Caution! Do not cover the + and – sign as they contain a integrated pressure relief mechanism.

Charging

Warning! Never charge the Li-ion battery with a charging current larger than the maximum charge current specified in chapter 3.2.3
Warning! Stop charging when the Li-ion battery switches to alarm mode (the external disconnect device will switch off).
Caution! To charge the Li-ion battery, use a charger which follow Super B’s charging profile (see charging manual which can be found on the Super B website).

1. Connect the charger to the Li-ion battery as described in paragraph 4.
2. Charge the Li-ion battery in case of an under-voltage shutdown or if the state of charge drops below 20% to preserve the lifespan of the Li-ion battery.

Battery balancing

During the battery lifespan, the cells within the Li-ion battery may be unbalanced due to high discharge currents and short float charge periods. This may result in a loss of capacity and unbalanced cells. The cells can be manually balanced by applying a constant voltage of 14.4 V and a current between 500mA and 800mA to the Li-ion battery

Reading the battery’s State of Charge (SoC)

The Li-ion battery’s State of Charge can only be read by CAN communication.

Battery Monitoring Software

Super B battery monitoring software offers the possibility to monitor the parameters of the Liion battery, such as cell voltage or temperature. It also enables one to download a complete recording of the Li-ion battery’s properties over time. The battery monitoring software and hardware are not included with the Li-ion battery. An overview of these products is given in paragraph 3.6.2.
