2.4 Overview
The SmartLi system consists of the battery modules, battery control unit (BCU), monitoring interface unit, power distribution unit (PDU), and monitoring display unit (MDU), which are integrated into a standard cabinet.
Battery modules are connected in series to provide energy. The BCU provides centralized battery management. The PDU connects power cables and disconnects the power circuit in case of exceptions. The MDU allows you to set parameters and query status.
When multiple battery cabinets are connected in parallel, the BCU balances the loads between cabinets to improve system reliability. The master battery cabinet provides an LCD that displays battery running information in real time and allows users to set battery parameters. Battery cabinets can connect to the UPS and network management system (NMS) for intelligent management.

3.4 Installing Cables
3.4.1 Cable Connection Reference
Context
WARNING Keep away from cabinets when preparing cables to prevent cable scraps from
entering the cabinets. Cable scraps may cause ignition during power-on and result in personal injury and device damage. After installing cables, clean the cabinet top, bottom, copper bar wiring positions, and other positions. Ensure that there is no dust or scraps inside and around cabinets. Prepare terminals onsite. The length of the copper wire should be the same as that of the part of the terminal that covers the conductor.
Procedure
Step 1 Route a cable into the cabinet and bind it to a nearby beam. Step 2 Pull the cable to the copper bar to which the cable is to be connected, determine
the cable length, and mark the cable at the position where the cable is to be cut. Step 3 Pull the marked cable out of the cabinet, cut the cable from the marked position,
strip the cable, and crimp a terminal.

IP address allocation
If the MDU is directly connected to a computer, the IP address can only be allocated manually. The IP addresses of the MDU and computer must be in the same network segment, and must be different.

Issue 07 (2021-03-22)

SmartLi 2.0 User Manual

4 User Interface

If the MDU is connected to a computer through a LAN switch or router with the DHCP function, the IP address can be allocated manually or automatically. Manual allocation is used by default.
Manual: Check that their IP addresses are two different values on the same network segment. Set the UPS IP address to be in the same subnet as the PC IP address. Perform the bitwise AND operation for the UPS IP address and the PC IP address with the subnet mask respectively. If the operation results are the same, the two IP addresses are in the same subnet.
AND operation rule: 1 AND 1 = 1, 1 AND 0 = 0, 0 AND 1 = 0, 0 AND 0 = 0. That is when the corresponding bits are both 1, the result is 1. In other cases, the result is 0.

long time and batteries cannot be charged in time. 3. After the cabinet is discharged, it cannot enter the charging state due to a
system fault. 4. Other scenarios that may trigger storage with low SOC
Regardless of scenarios involving storage with low SOC, charge battery modules within the maximum interval corresponding to the SOC when the cabinet is completely powered off. If the maximum interval is exceeded, the battery modules may be damaged due to overdischarge.
Maximum recharge interval corresponding to the SOC upon power-off:
SOC 10%: 30 days 8% SOC < 10%: 25 days 6% SOC < 8%: 20 days 4% SOC < 6%: 10 days
If the cabinet cannot be charged for a long time, power off the cabinet completely and recharge the battery modules at the maximum interval corresponding to the SOC. If the SOC is less than or equal to 4%, the battery modules need to be recharged immediately.

B Common Criteria

Safety Precautions
Avoid skin contact with electrolyte overflow. Before installing or maintaining battery modules, wear goggles, rubber gloves, and protective clothing.
Keep the battery module loop disconnected during installation and maintenance.
Secure battery module cables with a torque specified in the battery module documentation. Loose connections will result in excessive voltage drops or cause battery modules to burn out when the current is high.
Protect your skin and eyes from battery module electrolyte leakage. If your body comes in contact with electrolyte leakage, wash with clean water immediately and visit a doctor if the situation is serious.
Avoid ingestion of battery module components or substances.
Protect battery modules from mechanical vibration, collision, punctures, and strong impact. Otherwise, the battery modules may catch fire.
Do not throw battery modules in fire because this may cause the battery modules to ignite.
Do not immerse battery modules in water or expose them to rain.
Replacing a battery module with an incorrect model may cause cross current and bias current, which will trigger lithium battery protection. Long-time operation with an incorrect model will result in cell or board faults, which may cause risks such as fire.
If the battery module loop is short-circuited, lithium battery protection will be triggered and lithium batteries cannot be charged or discharged. Long-time frequent short circuiting can result in cell or board faults, which may cause risks such as fire.
Dispose of waste battery modules in strict accordance with local laws and regulations.
Misoperations
Avoid misuse of battery modules under the following conditions (including but not limited to):

Issue 07 (2021-03-22)

SmartLi 2.0 User Manual

B Common Criteria

Misoperatio n Reverse connection
External short circuit
Parallel connection

Protection Description
If terminals are connected with reverse polarity, the battery module will not start and will stay in sleep mode. If you hold down the MANUAL ON/OFF button to activate the battery module, it will report a protection alarm and the ALM indicator will be lit.
If the battery module loop is short-circuited, lithium battery protection will be triggered and lithium batteries cannot be charged or discharged. Long-time frequent short circuiting can result in cell or board faults, which may cause risks such as fire.
Battery modules cannot be directly connected in parallel. If they are forcibly connected in parallel, an excessive current may cause abnormal arcing and sparking, resulting in safety risks.

Under the preceding conditions, if the system circuit breaker is switched off and the auxiliary power supply is powered off, a battery module can be stored for 10 months with self power consumption of the system. If the battery module is not charged beyond this period, the cells of the entire lithium battery system may overdischarge, resulting in irreversible capacity loss. In this case, the battery module needs to be replaced.
Provide that a battery module is discharged for a long period and not charged. If the charging device is damaged or the battery module cannot be charged or recharged for a long period (30 days) after the system is powered off due to EOD, the cells of the entire lithium battery system may overdischarge due to power consumption of circuits such as the auxiliary power supply of the BCU in the cabinet, resulting in irreversible capacity loss. In this case, the battery module needs to be replaced.
[Scenario to be avoided]: Lithium batteries are started, but the charging device such as the UPS is not powered on, or the loop between the UPS and the lithium battery cabinet is disconnected. As a result, the lithium batteries cannot be recharged in a timely manner to ensure full charge.
Gas Composition
A battery module is an enclosed battery system and will not release any gases under normal operations.
If the battery module is severely misused, for example, being burned or thunderstruck, the battery may be damaged, resulting in electrolyte leakage. Because the electrolyte is of organic carbonate nature, it may produce CO2, CO, and N2 after being burned.
