Safety performance of energy storage equipment and its safeguard measures

The safety performance of energy storage equipment involves many aspects. The first is the stability of the battery. Whether it is a lithium-ion battery or other types of energy storage batteries, they may face the risk of thermal runaway during the charging and discharging process. Thermal runaway refers to the fact that a large amount of heat is generated inside the battery due to various reasons, and it cannot be effectively dissipated, which causes the battery temperature to rise sharply, which may cause the battery to bulge, burn or even explode. For example, when there is an abnormal situation such as a short circuit or electrolyte decomposition inside the battery, it is easy to trigger thermal runaway.

Secondly, the electrical safety of the energy storage system is crucial. In the operating environment of high voltage and high current, electrical faults such as insulation failure, overvoltage, and overcurrent may cause dangerous accidents such as arc discharge and electric shock. If the electrical protection device of the energy storage equipment is not perfect, once voltage fluctuations or current overloads occur, it may cause serious damage to the equipment itself and the power network connected to it.

In response to these safety hazards, a series of safeguards have emerged. At the level of battery design and manufacturing, the use of high-quality materials and advanced processes is the basis. For example, developing more stable electrolytes and improving the heat resistance and puncture resistance of battery separators can effectively reduce the probability of thermal runaway. At the same time, strict quality inspections are carried out on batteries, including accurate measurement of parameters such as battery capacity, internal resistance, and self-discharge rate, to screen out unqualified products and ensure the reliable performance of batteries put into use.

The thermal management system of the energy storage system is a key link in ensuring safety. Through liquid cooling, air cooling or phase change material cooling, the heat generated by the battery is taken away in time to maintain the battery within a suitable operating temperature range. For example, the liquid cooling system uses the circulation of coolant in the pipeline to transfer heat to the radiator for dissipation. The intelligent thermal management system can also automatically adjust the cooling intensity according to the real-time temperature of the battery, improving the heat dissipation efficiency while saving energy.

In terms of electrical safety, it is essential to be equipped with complete electrical protection devices. Overvoltage protection, overcurrent protection, leakage protection and other devices can act quickly at the moment of electrical faults, cut off the circuit, and prevent the accident from further expanding. In addition, the electrical insulation of the energy storage system should be regularly inspected and maintained to ensure good insulation performance and avoid electrical accidents caused by insulation aging or damage.

The installation and operating environment of energy storage equipment should not be ignored. It should be installed in a well-ventilated, dry place away from flammable materials and heat sources. During operation, a strict monitoring and early warning mechanism should be established to monitor the temperature, voltage, current and other parameters of the battery in real time through sensors. Once an abnormality is found, an alarm should be immediately issued and corresponding measures should be taken, such as starting the emergency cooling system or cutting off the power supply.

At the same time, personnel training and the formulation of safety regulations are equally important. Operators must undergo professional training, be familiar with the operating procedures and safety precautions of energy storage equipment, and strictly abide by relevant regulations during equipment maintenance and troubleshooting to avoid safety accidents caused by improper human operation.

The safety performance of energy storage equipment is a comprehensive subject, which requires effective safeguards from multiple aspects such as the battery itself, system design, thermal management, electrical protection, installation and operation environment, and personnel management. Only in this way can we ensure the safe and reliable operation of energy storage equipment, safeguard the efficient storage and utilization of energy, and promote the steady progress of energy storage technology on the path of sustainable energy development.
