In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship, unless otherwise specified.
The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
A method for judging the mis-charging of a lithium battery comprises the following main processes.
As shown in fig. 1:
step 1100: and acquiring the current unique identification information.
The unique identification information can be a two-dimensional code, a digital tag or a digital verification code, the unique identification information is preferably an electronic tag, the electronic tag can be arranged on the charger and also on the lithium battery, and the unique identification information can be arranged according to specific use scenes.
Step 1200: and comparing the current unique identification information with preset reference identification information.
After the unique identification information is acquired, reference identification information stored by the control terminal is called, and the unique identification information and the reference identification information are compared with each other; the unique identification information and the reference identification information correspond to the charger and the lithium battery one to one, namely, if the unique identification information corresponds to the lithium battery, the reference identification information corresponds to the charger.
The RFID reader-writer and the RFID tags are respectively arranged on the charger and the lithium battery in a one-to-one correspondence mode, namely if the RFID reader-writer is arranged on the charger, the RFID tags need to be arranged on the lithium battery, the RFID reader-writer is preferably arranged on the charger, the RFID tags are arranged on the lithium battery, and the RFID reader-writer is used for reading the RFID tags to obtain unique identification information of the lithium battery.
The remoteness of radio frequency identification technology is as follows:
radio Frequency Identification (RFID) is an abbreviation of Radio Frequency Identification, and the principle of the RFID is that non-contact data communication is carried out between a reader and a label to achieve the aim of identifying a target; after the tag enters the reader, the tag receives a radio frequency signal sent by the reader, product information stored in the chip is sent out by means of energy obtained by induced current, or a signal with a certain frequency is actively sent out by the tag, and the reader reads and decodes the information and sends the information to a central information system for related data processing.
RFID tags are classified (by communication) into three categories, passive, semi-passive (also called semi-active), active:
passive, passive tags do not have an internal power supply. The internal integrated circuit is driven by the received electromagnetic waves, which are emitted by the RFID reader. When the tag receives a signal of sufficient strength, it can send data to the reader. These data include not only an ID number (globally unique identification ID) but also data pre-existing in the EEPROM within the tag.
Semi-active, generally speaking, passive tag antennas have two tasks, the first: receiving the electromagnetic wave from the reader to drive the tag IC; secondly, the method comprises the following steps: when the tag returns a signal, the impedance of the antenna needs to be switched to generate a change between 0 and 1. The problem is that the antenna impedance must be designed to be "open and short" for best return efficiency, which in turn causes the signal to be totally reflected and not received by the tag IC. Semi-active is similar to passive, but with a small battery, power can just drive the tag IC, leaving the IC in an active state. This has the advantage that the antenna can be used for the purpose of receiving electromagnetic waves, and is sufficient for the purpose of returning signals. Compared with a passive mode, the semi-active mode has higher reaction speed and better efficiency.
The active tag itself has an internal power supply for supplying power required by the internal IC to generate an external signal, unlike the passive tag and the semi-passive tag. Generally, the active tag has a longer reading distance and a larger memory capacity for storing some additional information transmitted from the reader.
