In the safety requirements for lithium batteries, safety standards for charging and discharging operations and electricity usage are crucial. These standards aim to ensure the safety and reliability of the operation process and prevent accidents. The following are the main safety standards for lithium battery charging and discharging operations and electricity usage:
Work environment requirements: Lithium battery charging and discharging operations should be carried out in a well ventilated and temperature appropriate environment. This helps to prevent adverse conditions such as overheating and excessive humidity from affecting battery performance and safety. Meanwhile, the charging and discharging areas should be kept away from the core area and independent fire compartments should be set up to reduce potential safety risks.
Charger selection and use: Charging operations must use chargers that comply with relevant standards, specifications, and reliable quality. The charger should have safety requirements such as short circuit protection, automatic power off function, overcurrent protection function, and anti loss of control function. In addition, the battery pack should use a charger with balancing function to ensure that the charging status of each individual battery in the battery pack is balanced.
Battery inspection: Before conducting charging and discharging operations, it is necessary to check whether the battery is qualified. This includes confirming whether the battery has any abnormal conditions such as damage, deformation, leakage, smoking, or leakage. If there are any problems, charging and discharging operations are not allowed, and the battery should be disposed of safely in a timely manner.
Avoid overcharging and over discharging: During lithium-ion battery charging and discharging operations, overcharging and over discharging should be avoided. Overcharging may cause problems such as increased internal pressure and electrolyte leakage in the battery, while over discharging may lead to decreased battery performance and shortened lifespan. Therefore, the voltage and current during the charging and discharging process should be strictly controlled to ensure that the battery operates within a safe range.
Temperature control: Prevent charging and discharging lithium batteries in high or low temperature environments. High temperature may cause thermal runaway of the battery, while low temperature may affect the charging and discharging performance of the battery. In addition, the charging and discharging current of lithium batteries shall not exceed the maximum current indicated in the specifications.
Use power circuits that comply with national standards: When charging and discharging lithium batteries, power circuits that comply with relevant national electrical standards should be used to ensure the stability and safety of the power supply.
Lithium battery electrical equipment should have good insulation performance to prevent leakage and electric shock accidents. At the same time, the equipment should be properly grounded to ensure that current can be directed to the ground in the event of an electrical fault, protecting personnel safety.
Electrical connection and protection: The electrical connection of lithium batteries should be firm and reliable to prevent loosening or detachment. For exposed electrical parts, protective measures should be taken, such as wrapping with insulation materials or installing protective covers, to prevent accidental contact by personnel.
Regular inspection and maintenance: Regularly inspect and maintain lithium battery electrical equipment to ensure it is in good working condition. This includes checking for loose electrical connections, damaged insulation, and abnormal heating of the equipment.
Safety training and operating standards: Provide safety training to personnel operating lithium battery electrical equipment, so that they understand the safety performance, operating methods, and emergency measures of the equipment. At the same time, establish and strictly implement operating standards to ensure that personnel operate in accordance with prescribed procedures and requirements.
