The solution of intelligent vacuum cleane battery 2016-01-29
With the continuous improvement of living standards, the improvement of the home environment and the changes in consumer attitudes, the demand for vacuum cleaners will inevitably have a new breakthrough. In the next few years, China's vacuum cleaner industry will enter the stage of gold development, and the market prospect of vacuum cleaners is very broad. Market demand for vacuum cleaner batteries is also gradually improved, requiring energy saving, environmental protection, long cycle life, safe and stable, the use of environmental, operating temperature wide.
Design requirements of lithium battery for intelligent vacuum cleaner
According to the specifications that the market and customer requires, there are two types of intelligent vacuum cleaner batteries which are designed and matched with mainframe：
A
A, energy type: small motor vacuum cleaner, which has small instantaneous start and work current, can use energy type electric core (such as Samsung 22F/26F, SANYO, UR18650F, etc.);
B, power type: high power motor vacuum cleaner, which has big working current, adopt power type electric core. (such as Samsung 15Q/22P, Panasonic CH, KA, SONY, V3, etc.);

Combined with the above advantages and disadvantages, for example, a vacuum cleaner that needs a 14.8V/2200mAhbattery, just needs 4 battery cells to 4meet the requirements if using a lithium ion battery. Needs 12 battery cells to meet the requirements if using a Ni MH / Ni Cd battery. In terms of cost performance, lithium ion batteries have more advantages than NI-CD and NI-MH batteries. Because of high cost performance,the demands of longer time products is increasing. Therefore, more accurate solutions are needed in the design of intelligent vacuum cleaner batteries.
