How to use the lithium battery of the sweeping robot correctly?

Sweeping robots are designed to be wireless because they are not punctual and do not restrict area operations. This requires a lithium battery to supply it with power to maintain normal operations. The sweeping robot has particularly high requirements for lithium batteries, so the upgraded version of the sweeping robot now basically uses polymer lithium batteries because the polymer lithium battery is relatively safe. , The weight is relatively light, the voltage is high, the energy density of the same volume is much higher than that of nickel-hydrogen batteries and lead-acid batteries, and there is no charge-discharge memory effect. It can be used and charged, and its service life exceeds 700 times. Although the lithium battery of the sweeping robot has high capacity and long cycle life, improper use of the lithium battery will reduce the service life and capacity density of the lithium battery. The following key points should be paid attention to when using the lithium battery of the sweeping robot: Note one: Do not over-discharge the lithium battery. The discharge platform has a certain time. It depends on the power of the robot. If the robot has 20% of the lithium battery power left during operation, it continues to work and runs out of power until the robot is not working. This causes the over-discharge of the lithium battery, which often reduces the service life of the lithium battery. It is still quite expensive to replace a lithium battery on a general robot, so it is still necessary to pay attention to proper maintenance. Note 2: Use the manufacturer's original charger to charge the lithium battery, and a dedicated lithium battery charger should be used. The CC/CV method (constant current + constant voltage) is used for lithium battery charging, which means that it is charged with a constant current first, and when the voltage reaches 4.2V*n, it is converted to constant voltage charging until the current is reduced to 0.01C. When charging stops. Note 3: When not in use for a long time, the lithium battery should be charged to 95% before storage. The storage, transportation and shipment of the lithium battery should not be left empty. The storage, transportation and shipment of the lithium battery are all in a half-charged state, and the voltage is almost 3.83V. Fully charged (4.18-4.19V) is prone to safety accidents, and the polymer lithium battery soft packs may cause swelling. The dead battery condition (below 3.0V) will damage the battery greatly, and the electrode data lattice will collapse seriously. Reading the following set of data is clear: the percentage is the percentage of the saturation condition relative to the initial value. Storage temperature 40% charging condition 100% charging condition 0 degrees 98% (one year in the future) 94% (one year in the future) 25 degrees 96% (one year in the future) 80% (one year in the future) 40 degrees 85% (one year in the future) 65% (one year in the future) 60 degrees 75% (one year in the future) 60% (three months in the future) Obviously, If you want to store the battery for a long time, try to put it in a boring and low temperature environment and keep the remaining battery power at about 40%. Of course, it is best to use the battery once a month to ensure the excellent storage condition of the battery. It will not let the battery be completely lost and damage the battery. Note 4: When storing lithium batteries, pay attention to the dry air. The temperature is theoretically better. However, combined with the current status of civilian batteries, most manufacturers make batteries that are too low temperature will damage the internal structure. Therefore, it is better to stay at room temperature around 20. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
