What are the safety requirements for lithium battery charging and discharging operations and electricity consumption?
Lithium battery safety requirements, for charging and discharging operations and electricity safety standards are crucial, these standards are designed to ensure that the operation process is safe and reliable, to prevent accidents. The following are the main safety standards for lithium battery charging and discharging operations and electricity consumption:
First, charge and discharge operation safety standards:
Operating environment requirements: lithium battery charging and discharging operations need to be carried out in a ventilated and suitable temperature environment. This helps prevent adverse conditions such as overheating and excessive humidity from affecting battery performance and safety. At the same time, the charge and discharge area should be far away from the core area, and an independent fire zone should be set up to reduce potential safety risks.
Charger selection and use: The charging operation must choose a charger that meets the relevant standards and specifications and is of reliable quality. The charger should have short circuit protection, automatic power off function, overcurrent protection function, anti-loss function and other safety requirements. In addition, the battery pack should use a charger with a balance function to ensure that the charging state of each single battery in the battery pack is balanced.
Battery check: Before charging and discharging the battery, check whether the battery is qualified. This includes confirming whether the battery has any abnormal conditions such as damage, deformation, leakage, smoke, and leakage. If there is a problem, do not carry out charging and discharging operations, and promptly dispose of the battery safely.
Avoid overcharge and overdischarge: Avoid overcharge and overdischarge when charging and discharging lithium-ion batteries. Overcharge may lead to problems such as increased internal pressure and electrolyte leakage, while overdischarge may lead to reduced battery performance and shortened battery life. Therefore, the voltage and current in the charge and discharge process should be strictly controlled to ensure that the battery works within a safe range.
Temperature control: prevent charging and discharging of lithium batteries in high or low temperature environments. High temperatures may lead to thermal runaway of the battery, while low temperatures may affect the charge and discharge performance of the battery. In addition, the charge and discharge current of the lithium battery shall not exceed the maximum current marked in the specification.
Use power circuits that meet national standards: lithium battery charging and discharging operations should use power circuits that meet relevant national electrical standards to ensure the stability and safety of the power supply.
Second, electricity safety standards:
Equipment insulation and grounding: 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 the current can be imported to the ground in the event of an electrical failure to protect the safety of personnel.
Electrical connection and protection: The electrical connection of the lithium battery should be firm and reliable to prevent loosening or falling off. For exposed electrical parts, protective measures should be taken, such as wrapping with insulation materials or installing protective covers to prevent personnel from touching them by mistake.
Regular inspection and maintenance: Regular inspection and maintenance of lithium battery electrical equipment to ensure that it is in good working condition. This includes checking for loose electrical connections, broken insulation, and abnormal heating of equipment.
Safety training and operation specifications: Conduct safety training for personnel operating lithium battery electrical equipment, so that they can understand the safety performance, operation methods and emergency measures of the equipment. At the same time, develop and strictly implement the operation specifications to ensure that personnel operate in accordance with the specified procedures and requirements.
In summary, the safety standards for charge and discharge operations and electricity consumption in the safety requirements of lithium batteries cover many aspects, from the operating environment, equipment selection, battery inspection to the insulation and grounding of electrical equipment are clearly stipulated. The implementation of these standards helps to ensure that lithium batteries are safe and reliable during use and reduce the risk of accidents.
