Problems solved by technology
[0002] With the advancement of science and technology and the development of battery technology, electric energy is more and more widely used as power. At this stage, power batteries include lead-acid batteries and lithium-ion batteries. As we all know, each battery has its own charging characteristics, so a large amount of charging A device is a device equipped with a charger. Different devices cannot be charged with the same charger. The reason is that different devices use different charging voltages and charging currents (for example, the charging voltages of different models of mobile phones are 4.4V and 5V respectively), that is The charging curve is inconsistent, if forced to charge, it will damage the device
When electronic equipment is eliminated, charging equipment is also eliminated, resulting in a lot of waste

The invention relates to the lithium battery pack charging technology field and especially relates to an automatic protection lithium battery pack based on radio frequency identification control. The battery pack is characterized in that a shell is arranged; a controller and a charging circuit are arranged in the shell; a radio frequency reader and writer and a radio frequency antenna are arranged; the radio frequency reader and writer and the radio frequency antenna are connected; the radio frequency reader and writer and the controller are connected; a display and an operation keyboard are arranged; the display and the operation keyboard are connected to the controller respectively; and the display and the operation keyboard are arranged outside the shell. Compared to the prior art, by using the battery pack of the invention, a problem that batteries with different specifications have diversities during being charged can be effectively solved; and a radio frequency reading and writing mechanism is used to carry out identification so that a speed is fast and identification is accurate.
Description
Technical field: [0001] The invention relates to the technical field of charging management of lithium battery packs, in particular to an automatic protection lithium battery pack based on radio frequency identification control. Background technique: [0002] With the advancement of science and technology and the development of battery technology, electric energy is more and more widely used as power. At this stage, power batteries include lead-acid batteries and lithium-ion batteries. As we all know, each battery has its own charging characteristics, so a large amount of charging A device is a device equipped with a charger. Different devices cannot be charged with the same charger. The reason is that different devices use different charging voltages and charging currents (for example, the charging voltages of different models of mobile phones are 4.4V and 5V respectively), that is The charging curve is inconsistent, and if you try to charge it forcibly, it will damage the ...
