Lithium ion battery of intelligent sweeper (keyword: sweeper battery, intelligent sweeper)


As the development of economy, people has more and more exquisite requirement on material life and spiritual needs., more and more intelligent devices are applied by civilians. Floor mopping robot is also named sweeper for lazy people, which is an intelligent household appliance that cleans the floor automatically. It can detect on the size of the room, furniture position, cleaning status of the ground, etc. and come out a proper cleaning route by its inside program. It is called robot for its intelligence. Since intelligent sweeper comes into tens of thousands of family, people have more requirements on the battery of the sweeper, such as environmentally friendly, long cycle life, safe and stable, and widely temperature adaptation of different area.
