Problems solved by technology

However, this method will be limited in many applications. For example, the cable connected to the main circuit has a large current and a large volume, while the communication cable has a small current and a small volume. Inserting the two cables into the same interface will cause inconvenient operation, difficult interface design, and hardware high cost

Embodiment Construction

[0051] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0052] figure 1 is a schematic flowchart of a method for identifying the validity of a physical connection provided by an embodiment of the present application.

[0053] In this embodiment, the implementation of the charger is taken as an example for description.

[0054] Such as figure 1 As shown, the method of the present embodiment includes:

[0055] S11: The charger establishes a physical connection and a wireless communication connection with the lithium battery.

[0056] For example, the charger and the lithium battery are respectively provided with wireless communication modules, so as to establish a wireless communication connection through the wireless communication modules. The wireless communication module is, for example, a wifi module.

[0057] When the charger needs to charge the lithium battery, a physical connection needs to be es...

Abstract

The present invention relates to a method and device for identifying the validity of a physical connection between a charger and a lithium battery. The method comprises a step of establishing a physical communication connection and a wireless communication connection between the charger and the lithium battery, a step of allowing the charger to obtain a first encoded value and determining a current value according to the first encoded value, a step of transmitting a current to the lithium battery according to the current value by using the physical connection such that the lithium battery determines a second encoded value according to the inputted current, a step of receiving a second encoded value which is sent by the lithium battery through the wireless communication connection, and a step of comparing the first encoded value and the second encoded value and identifying the validity of the physical connection according to a comparison result. According to the method and the device, the adding of a communication cable is not needed when the validity of the physical connection is identified, and the problem caused by the use of the communication cable is avoided.

Description

technical field [0001] The present application relates to the technical field of electronic communication, in particular to a method, device and system for identifying the validity of a physical connection. Background technique [0002] When the charger charges the lithium battery, a physical connection is generally established to charge the lithium battery through the physical connection. The physical connection can be called the main circuit connection, which is usually composed of positive and negative extremely high current cables. In order to ensure that the charger charges the lithium battery normally, it is necessary to confirm whether the physical connection between the charger and the lithium battery is valid. Valid means that the physical connection is successfully established, and invalid means that the physical connection is not successfully established. Especially in the scenario of batch charging, there will be a situation where a large number of chargers and a...
