Specific implementation mode
The present invention is described in detail below with reference to the accompanying drawings and embodiments.
Fig. 1 is the flow diagram of the recognition methods for the physical connection validity that the application one embodiment provides.
The present embodiment is illustrated by taking the execution of charger as an example.
As shown in Figure 1, the method for the present embodiment includes：
S11：Charger establishes physical connection with lithium battery and wireless communication connects.
For example, being respectively arranged with wireless communication module in charger and lithium battery, nothing is established with module by radio communication
Line communicates to connect.Wireless communication module is, for example, wifi module.
When charger needs to charge for lithium battery, need to establish physical connection between charger and lithium battery, although filling
Although establishing physical connection between electric appliance and lithium battery, which can not necessarily be successfully established, need to be by wireless
Communication transfer data information is identified.
S12：Charger obtains the first encoded radio, and current value is determined according to the first encoded radio.
Wherein, the first encoded radio can be default and pre-stored, therefore, can be read from pre-stored data
Get the first above-mentioned encoded radio.First encoded radio can be binary data, for example,：11001.
Furthermore it is also possible to the correspondence between encoded radio and current value be pre-set, to according to above-mentioned corresponding pass
System, current value is determined by the first encoded radio.
Above-mentioned correspondence can be the current value that a binary data corresponds to a cycle, for example, 0 corresponds to one
The 3A in a period, 1 corresponds to the 4A of a cycle.Alternatively, above-mentioned correspondence, can also be that a binary data correspondence is more
The current value in a period.It does not limit, can be set according to actual needs herein specific corresponding to relationship.
By taking the first encoded radio is binary data as an example, then the data of the first encoded radio are 0 or 1, are pre-set above-mentioned
Correspondence, the present embodiment, by taking a binary data corresponds to the current value in multiple periods as an example.Specifically, 0 pair can be arranged
It is larger current value to answer a cycle, and second period is smaller current value, and 1 correspondence a cycle is larger
Current value, second period and third period are smaller current value, for example, t=500ms is a cycle, it is larger
Current value is 4A, and smaller current value is 3A, and transmission 4A electric currents, second 500ms in first 500ms are corresponded to referring to Fig. 2,0
Interior transmission 3A electric currents；1 corresponds to transmission 4A electric currents in first 500ms, and 3A electric currents, third 500ms are transmitted in second 500ms
Interior transmission 3A electric currents, then on the basis of the above, by taking the first encoded radio is 11001 as an example, it is determined that going out current value is
4334334343433。
S13：Charger uses the physical connection, electric current is transmitted to the lithium battery according to the current value, so that institute
It states lithium battery and the second encoded radio is determined according to the electric current of input.

Interior transmission 4A electric currents, second 500ms is interior to transmit 3A electric currents, and 3A electric currents are transmitted in third 500ms, and so on.
After lithium battery is entered electric current, the value of electric current can be read according to the period, and the second coding is determined according to current value
Value.Correspondence similar with charger side implementation principle, can also being pre-configured in lithium battery between current value and encoded radio,
To which lithium battery can determine the second encoded radio according to the correspondence by current value.It is understood that charger and lithium
Correspondence between the current value and encoded radio that are configured in battery is identical, and the period for sending and reading is also identical, for example,

3A electric currents are transmitted in second 500ms, and 3A electric currents are transmitted in third 500ms.Thus, it is supposed that lithium battery was read per 500ms
Current value is 4334334343433, then the second encoded radio that lithium battery is determined is 11001.
S14：Charger receives the second encoded radio that lithium battery is sent by the wireless communication connection.
It can by radio communication be connected after determining the second above-mentioned encoded radio and be sent to charging by lithium battery
Device.
S15：Charger first encoded radio and second encoded radio identify the physics according to comparison result
The validity of connection.
Wherein, the validity of physical connection is identified according to comparison result, including：
If the first encoded radio is identical as the second encoded radio, identify that physical connection is effective；Alternatively, if first
Encoded radio is differed with the second encoded radio, then identifies that physical connection is invalid.

To be charged to lithium battery according to normal flow.
Above-mentioned physical connection is invalid, then shows that corresponding physical connection is not successfully established, later, charger can
To be adjusted to new physical connection, and the validity of new physical connection is identified, will pass through effective physical connection
It charges to lithium battery.
For example, under the scene of electric vehicle charging, it is assumed that charging pile can be that three kinds of specifications are 200V/220V/ respectively
The electric vehicle of 250V charges, after charging interface and the electric vehicle of charging pile, which are established, to be connected, i.e. physical connection
It establishes and completes, but whether physical connection effectively need to further identify.At this moment, charging pile first can pass through charging wire with 200V specifications
Electric current is sent to electric vehicle, and receives whether the data information detection physical connection that electric vehicle is fed back by radio communication builds
Stand successfully, if physical connection is successfully established, you can charge to electric vehicle according to normal flow, if physical connection not at
Work(is established, then charging pile need to readjust specification information and such as be adjusted to 220V, again to electric vehicle transmission electric current and to new
The validity of physical connection is identified.
It is understood that above-mentioned charger can be applied to one-to-one charging scenarios to lithium battery charging, alternatively,
The scene of batch charging can also be applied to.
In the present embodiment, by establishing wireless communication connection, and the second encoded radio of transmission is connected by radio communication, and the
Two encoded radios are that lithium battery parses the charging current transmitted in physical connection, and, compare the first encoded radio
With the second encoded radio, the validity of physical connection is identified, it may not be necessary to be identified using communication cable, to avoid using logical
The problem of communication cable causes.Further, by determining current value according to the first encoded radio, electric current is transmitted further according to current value,
It may be implemented to levy the first encoded radio with ammeter, effectively be transmitted into row information to more convenient.
