Battery Safety
Before installing, operating, or maintaining batteries, read the battery manufacturer's instructions. Observe the safety precautions provided in this document which are supplemental to the safety instructions provided by the battery manufacturer.
Do not short-circuit the positive and negative poles of batteries. Battery short circuits can generate high instantaneous current, which may cause battery leakage, overheating, fire, or explosion. To avoid battery short circuit, do not maintain batteries with power on.
Do not expose batteries at high temperatures or around heat-generating sources, such as high-temperature sunlight, fires, transformers, and heaters. Battery overheating caused by external heat sources may cause vent opening, leakage, fire, or explosions.
Protect battery modules from mechanical vibration, collision, punctures, and strong impact. Otherwise, the modules may catch fire.
To avoid leakage, overheating, fire, or explosions, do not disassemble, alter, or damage batteries, for example, insert sundries into batteries, squeeze batteries, or immerse batteries in water or other liquids.
Do not burn batteries. Otherwise, the batteries may catch fire or explode.
There is a risk of explosion if the model of the replaced battery is incorrect. The battery should be replaced with a battery of the model recommended by the manufacturer.
It is recommended that an independent battery room be used. Before installing battery modules, prepare fire extinguishing facilities, such as firefighting sands and liquid carbon dioxide fire extinguishers, according to the construction regulations. Before operation, ensure that the battery room is equipped with a fire extinguishing system that complies with local regulations.
Before unpacking battery modules, ensure that the packing cases are intact and correctly placed according to the labels on the packing cases during their storage and transportation. Do not place a battery module upside down, lay it on one side, or tilt it. Stack the battery modules according to the stacking requirements on the packing cases. Any bumping or falling may damage the battery modules.
After unpacking battery modules, place them in the required direction. Do not place a battery module upside down or vertically, lay it on one side, tilt it, or stack it with other modules. Any bumping or falling may damage the battery modules.
Install the equipment in an area far away from liquids. Do not install it under areas prone to condensation, such as under water pipes and air exhaust vents, or areas prone to water leakage, such as air conditioner vents, ventilation vents, or feeder windows of the equipment room. Ensure that no liquid enters the equipment to prevent faults or short circuits.
- Battery modules should be used soon after being deployed. For battery modules that have been stored for an extended period, recharge them periodically according to the instructions for battery module recharge. Otherwise, the battery modules may be damaged.
- After the battery system is installed, fully charge batteries (the SOC reaches 100%) and then put them into use. Exercise caution to replace a battery module unless it is faulty.
- If the battery system is powered off for installation or commissioning or batteries are not charged in time after discharge, recharge the battery cabinet in time by referring to the instructions for recharging batteries with low SOC. Otherwise, batteries may be damaged due to overdischarge.
General Requirements
- If a battery is accidentally exposed to water, do not install it. Move it to a safe place for isolation and contact technical engineers in a timely manner.
- Keep the battery switch off during installation and maintenance.
- When installing batteries, do not place installation tools on the batteries. After the installation is complete, clean up the objects on the batteries and the surrounding area.
- Use batteries of specified models. Using batteries of other models may damage the batteries.
- Note the polarities when installing batteries. Do not short-circuit the positive and negative poles of the same battery or battery string. Otherwise, the battery may be short-circuited.
- Exercise caution when setting battery parameters. Incorrect settings will affect the power supply and battery lifespan.
- Do not charge a battery when the ambient temperature is below the lower limit of the operating temperature (charging is forbidden at 0°C). Low-temperature charging may cause crystallization, which will result in a short circuit inside the battery.
- Dispose of waste batteries in accordance with local laws and regulations. Do not dispose of batteries as household waste. If a battery is disposed of improperly, it may explode.
To ensure battery safety and battery management accuracy, use batteries provided by the Company. The Company is not responsible for any battery faults caused by batteries not provided by it.
Battery Leakage
- If a battery leaks, wear goggles, rubber gloves, and protective clothing, power off the equipment in a timely manner, remove the leaking battery module from the cabinet, and contact technical support.
- If a battery overflows, protect the skin or eyes from the leaking liquid. If the skin or eyes come in contact with the leaking liquid, wash it immediately with clean water and go to the hospital for medical treatment.
Flammable Gas
- A battery module is an enclosed battery system and will not release any gases under normal operations.
- If a battery module is improperly treated, for example, burnt, needle-pricked, squeezed, overcharged, or subject to other adverse conditions that may cause battery thermal runaway, the battery may be damaged or an abnormal chemical reaction may occur inside the battery, resulting in electrolyte leakage or production of gases such as CO2, CO, N2, and H2. To prevent fire or corrosion, ensure that flammable gas (such as hydrogen) is properly exhausted.
