Logical operations also sends the signal to the controller of each assembly；Or, this control device can also include nothing
Line communication module, i.e. obtains the identification code of battery bag, this wireless communication module example by wireless communication module
As being support general packet radio service technology (General Packet Radio Service, GPRS)
With the wireless communication module of short message dual-channel transmission data, or can be support multicenter data communication
Wireless communication module.The method of Fig. 7 includes:
710, determine that battery system is in connection status with the battery base of electric automobile, wherein, electronic
Automobile is removably connected with battery system by battery base, and battery system includes at least two battery bag.
720, determine whether at least two battery bag belongs to same battery system.
For example, it is possible to it is the most consistent to detect the model of at least two battery bag, parameter, the date of production etc..
Or, can be that each battery bag arranges an identification code, by detecting the identification of at least two battery bag
Whether code is mutually matched so that it is determined that whether this at least two battery bag belongs to same battery system.
730, in the case of at least two battery bag belongs to same battery system, controlling battery system is
Electric automobile is powered.
In the embodiment of the present invention, when detecting that at least two battery bag belongs to same battery system, use
Cell system power；When detecting that at least two battery bag is not belonging to same battery system, do not use electricity
Cell system is powered, and so ensure that the power supply performance of electric automobile.
Alternatively, as an embodiment, step 720 comprises the steps that the knowledge obtaining at least two battery bag
Other code, wherein, the corresponding identification code of each battery bag；Determine the identification that at least two battery bag is corresponding
Whether code mates；In the case of the identification code coupling that at least two battery bag is corresponding, determine at least two
Battery bag belongs to same battery system；In the unmatched situation of identification code that at least two battery bag is corresponding
Under, determine that at least two battery bag is not belonging to same battery system.
Specifically, each battery bag can have corresponding unique identification code, and this identification code is such as
It can be the identification code of pseudorandom numbers maker stochastic generation.
Should be understood that the mode obtaining identification code corresponding to battery bag can have multiple.In one example,
The identification code of described acquisition at least two battery bag may include that the battery management system with battery
(Battery Management System, BMS) communicates, it is thus achieved that the identification code of battery bag.Certainly,
Can also be obtained the identification code of battery bag by other detection meanss, this is not made specifically by the embodiment of the present invention
Limit.
Should be understood that and determine that the mode whether identification code that at least two battery bag is corresponding mates can have many
Kind, this is not especially limited by the embodiment of the present invention.In one example, described determine at least two electricity
The identification code that pond bag is corresponding whether mate may include that by the identification code of at least two battery bag with deposit in advance
The identification code being mutually matched of storage compares, to determine that the identification code that this at least two battery bag is corresponding is
No coupling.Or, the matching algorithm preset can be used to calculate two knowledges based on the identification code got
Whether other code mates.
Alternatively, as an embodiment, the method for Fig. 7 may also include that and determines the current of battery system
Whether state is suitable for electric automobile is powered；Step 730 comprises the steps that the identification at least two battery bag
Code coupling, and the current state of battery system is suitable in the case of electric automobile powers, and controls battery system
System is powered for electric automobile.
Such as, described electric automobile can be provided with control device, and each battery bag in battery system can
To have corresponding identification code (can be unique identification code), battery bag accesses described electric motor car
Circuit in can be provided with switch (can be such as metal-oxide semiconductor (MOS) (Metal Oxide
Semiconductor, MOS) pipe), battery bag, switch and control device and be serially connected, can be formed
Loop.When two battery bags (the two battery bag is the battery bag being serially connected) are by described plug-in type
When connected mode is concurrently accessed described circuit, first described control device can identify the knowledge of each battery bag
Other code.Such as, controlling device can communicate with the BMS in battery system, obtains each battery bag
Identification code.Then, control device and may determine that two battery bags meet 2 conditions the most simultaneously.Condition
1: whether said two battery bag belongs to same battery system；Condition 2: the state of described battery system is
The no electric automobile that is suitably for powers (or the state of described battery system is if appropriate for electric discharge).If above-mentioned two
