Storage and maintenance of lithium battery for electric sweeper

The storage and maintenance of lithium batteries and the safety protection of electric sweepers. Sanitation sweepers have now entered the electric era. There are more and more electric sweepers, and domestic sales are also rising. This article first analyzes the lithium battery storage maintenance and safety protection standards of lithium battery sweepers. 1. Store the lithium battery for a short time and not use it for a short time (such as within 6 months). When the battery is energized, the battery should be stored in a place where there is no corrosive gas at -20C~35C~65±20%, and the temperature and humidity are monotonous. Higher or lower temperature and humidity can rust the metal parts of the battery or leak the battery. Long-term storage 1. Lithium batteries should not be charged 50% to 70% of the power for a long time (such as more than 6 months). From the dull and cool environment of the instrument, recharge the battery every three months to prevent too long storage time. The low power of the battery due to self-discharge constitutes an irreversible capacity and is thrown away. 2. The self-discharge of lithium batteries is affected by ambient temperature and humidity. High temperature and humidity will accelerate the self-discharge of the battery. Charging and charging control 1. Charging method: (1) The original factory-supplied battery uses special battery equipment; it is charged by the customer or installed on the equipment with a storage battery. Filling: Lithium batteries have a relatively complete general maintenance function (board) maintenance and other batteries do not require much maintenance, but in order to prevent the maintenance of the board responsible for the failure of maintaining functional safety issues, charging for a long period of time is not recommended. After the battery is fully charged, It is necessary to use original or other rechargeable battery chargers, according to the operation and use, otherwise the battery may be damaged or even risk; 2. Battery identification and detection method: 50%~70% battery, generally the corresponding voltage range is 3.6v~3.9v (lithium Different battery materials and systems are different); users or operators can use a multimeter to measure the voltage of the two poles, such as the power displayed on the instrument or equipment. Storage warehouse requirements 1. The warehouse can control temperature and humidity, such as air conditioning or dehumidification equipment, which can prevent long-term high humidity environments. 2. The warehouse is equipped with an active rescue system, an emergency sprinkler system, a dry powder rescue device, and fire-fighting sand (sand for construction). 3. Flammable items (such as cartons, cartons, etc.) should not be stored in the same warehouse, and independent warehouses should be used. 4. Secondary fire doors. 5. According to the instructions on the packaging and stacking requirements of lithium batteries, prevent the stacking layer from exceeding the limit.
