Issue 07 (2021-03-22) Copyright © Huawei Technologies Co., Ltd. 154 SmartLi 2.0 User Manual B Common Criteria 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) Copyright © Huawei Technologies Co., Ltd. 155 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.

Capacity loss or irreversible damage is caused to battery modules because they are not charged in a timely manner and stored over due to customer reasons. After battery modules are installed at a site and connected to the system, they are damaged due to overdischarge because they are not powered on in a timely manner due to customer reasons. Battery modules are damaged because they are not accepted in a timely manner due to customer reasons. Battery modules are damaged because the operating environment or external power specifications do not meet environmental requirements. For example, the operating temperature is poor, power outages occur frequently, battery modules are frequently overdischarged due to improper maintenance, the capacity of a customer site is expanded, or battery modules are not fully charged for a long period. No air conditioner is available onsite, or the ambient humidity is too high. As a result, the PCB and components are corroded, affecting the product reliability and quality. The product cannot be used properly or is even damaged. The customer changes the application scenarios of battery modules without notifying Huawei. Issue 07 (2021-03-22) Copyright © Huawei Technologies Co., Ltd. 157 SmartLi 2.0 User Manual C Warranty Rules Battery modules are damaged due to the reasons of the customer or a third party, such as reallocating or reinstalling battery modules without following Huawei's requirements. The customer incorrectly sets operating management parameters for battery modules. The parameters include but are not limited to battery module capacity, quantity, equalized charging voltage, float charging voltage, charge current limit, and disconnection voltage. The customer fails to follow the Quick Guide or User Manual in battery module maintenance. For example, the customer does not periodically check whether the terminal screws of battery modules are tightened. The customer connects extra loads to battery modules. The customer uses the battery modules provided by Huawei together with other battery modules, which causes the acceleration of capacity decrease. For example, the customer uses Huawei's battery modules together with battery modules of other brands, with battery modules of different rated capacity, or with old battery modules.
